Installing Using Anaconda

This chapter provides step-by-step instructions for installing Fedora using the Anaconda installer. The bulk of this chapter describes installation using the graphical user interface. A text mode is also available for systems with no graphical display, but this mode is limited in certain aspects (for example, custom partitioning is not possible in text mode).

If your system does not have the ability to use the graphical mode, you can:

  • Use Kickstart to automate the installation as described in Automating the Installation with Kickstart

  • Perform the graphical installation remotely by connecting to the installation system from another computer with a graphical display using the VNC (Virtual Network Computing) protocol - see Installing Using VNC

Introduction to Anaconda

The Fedora installer, Anaconda, is different from most other operating system installation programs due to its parallel nature. Most installers follow a fixed path: you must choose your language first, then you configure network, then installation type, then partitioning, etc. There is usually only one way to proceed at any given time.

In Anaconda you are only required to select your language and locale first, and then you are presented with a central screen, where you can configure most aspects of the installation in any order you like. This does not apply to all parts of the installation process, however - for example, when installing from a network location, you must configure the network before you can select which packages to install.

Some screens will be automatically configured depending on your hardware and the type of media you used to start the installation. You can still change the detected settings in any screen. Screens which have not been automatically configured, and therefore require your attention before you begin the installation, are marked by an exclamation mark. You can not start the actual installation process before you finish configuring these settings.

Additional differences appear in certain screens; notably the custom partitioning process is very different from other Linux distributions. These differences are described in each screen’s subsection.

Consoles and Logging During the Installation

The following sections describe how to access logs and an interactive shell during the installation. This is useful when troubleshooting problems, but should not be necessary in most cases.

Accessing Consoles

The Fedora installer uses the tmux terminal multiplexer to display and control several windows you can use in addition to the main interface. Each of these windows serves a different purpose - they display several different logs, which can be used to troubleshoot any issues during the installation, and one of the windows provides an interactive shell prompt with root privileges, unless this prompt was specifically disabled using a boot option or a Kickstart command.

In general, there is no reason to leave the default graphical installation environment unless you need to diagnose an installation problem.

The terminal multiplexer is running in virtual console 1. To switch from the actual installation environment to tmux, press Ctrl+Alt+F1. To go back to the main installation interface which runs in virtual console 6, press Ctrl+Alt+F6.

If you choose text mode installation, you will start in virtual console 1 (tmux), and switching to console 6 will open a shell prompt instead of a graphical interface.

The console running tmux has 5 available windows; their contents are described in the table below, along with keyboard shortcuts used to access them. Note that the keyboard shortcuts are two-part: first press Ctrl+b, then release both keys, and press the number key for the window you want to use.

You can also use Ctrl+b n and Ctrl+b p to switch to the next or previous tmux window, respectively.

Table 1. Available tmux Windows
Shortcut Contents

Ctrl+b 1

Main installation program window. Contains text-based prompts (during text mode installation or if you use VNC direct mode), and also some debugging information.

Ctrl+b 2

Interactive shell prompt with root privileges.

Ctrl+b 3

Installation log; displays messages stored in /tmp/anaconda.log.

Ctrl+b 4

Storage log; displays messages related storage devices from kernel and system services, stored in /tmp/storage.log.

Ctrl+b 5

Program log; displays messages from other system utilities, stored in /tmp/program.log.

In addition to displaying diagnostic information in tmux windows, Anaconda also generates several log files, which can be transferred from the installation system. These log files are described in Log Files Generated During the Installation, and directions for transferring them from the installation system are available in Transferring Log Files from the Installation System.

Saving Screenshots

You can press Shift+Print Screen at any time during the graphical installation to capture the current screen. These screenshots are saved to /tmp/anaconda-screenshots.

Additionally, you can use the autostep --autoscreenshot command in a Kickstart file to capture and save each step of the installation automatically. See autostep (optional) - Go Through Every Screen for details.

Installing in Text Mode

Text mode installation offers an interactive, non-graphical interface for installing Fedora. This may be useful on systems with no graphical capabilities; however, you should always consider the available alternatives before starting a text-based installation. Text mode is limited in the amount of choices you can make during the installation.

There are two alternatives to text mode which can both be used even if the installation system does not have a graphical display. You can either connect to the installation system using VNC and perform an interactive graphical installation remotely (see Installing Using VNC), or you can create a Kickstart file to perform the installation automatically (see Automating the Installation with Kickstart).

The main menu in during a text-based installation.
Figura 1. Text Mode Installation

Installation in text mode follows a pattern similar to the graphical installation: There is no single fixed progression; you can configure many settings in any order you want using the main status screen. Screens which have already been configured, either automatically or by you, are marked as [x], and screens which require your attention before the installation can begin are marked with [!]. Available commands are displayed below the list of available options.

Limits of interactive text mode installation include:

  • The installer will always use the English language and the US English keyboard layout. You can configure your language and keyboard settings, but these settings will only apply to the installed system, not to the installation.

  • You can not configure any advanced storage methods (LVM, software RAID, FCoE, zFCP and iSCSI).

  • It is not possible to configure custom partitioning; you must use one of the automatic partitioning settings. You also cannot configure where the boot loader will be installed.

To start a text mode installation, boot the installation with the inst.text boot option used either at the boot command line in the boot menu, or in your PXE server configuration. See Booting the Installation for information about booting and using boot options.

Installing in the Graphical User Interface

The graphical installation interface is the preferred method of manually installing Fedora. It allows you full control over all available settings, including custom partitioning and advanced storage configuration, and it is also localized to many languages other than English, allowing you to perform the entire installation in a different language. The graphical mode is used by default when you boot the system from local media (a CD, DVD or a USB flash drive).

The sections below discuss each screen available in the installation process. Note that due to the installer’s parallel nature, most of the screens do not have to be completed in the order in which they are described here.

Each screen in the graphical interface contains a Help button. This button opens the Yelp help browser displaying the section of the Fedora Installation Guide relevant to the current screen.

You can also control the graphical installer with your keyboard. Use Tab and Shift+Tab to cycle through active control elements (buttons, check boxes, etc.) on the current screen, Up and Down arrow keys to scroll through lists, and Left and Right to scroll through horizontal toolbars or table entries. Space or Enter can be used to select or remove a highlighted item from selection and to expand and collapse drop-down menus.

Additionally, elements in each screen can be toggled using their respective shortcuts. These shortcuts are highlighted (underlined) when you hold down the Alt key; to toggle that element, press Alt+X, where X is the highlighted letter.

Your current keyboard layout is displayed in the top right hand corner. Only one layout is configured by default; if you configure more than layout in the Keyboard Layout screen (Keyboard Layout), you can switch between them by clicking the layout indicator.

Welcome Screen and Language Selection

The first screen displayed immediately after the graphical installer starts is the Welcome screen.

Screenshot of the Welcome screen showing language selection options.
Figura 2. Welcome Screen

First, select your preferred language in the left hand side column, and then select your locale from the right hand side column. You can use the text input field in the bottom left corner to search for your language instead of looking for it in the full list of more than 70 languages.

The language you select on this screen will be used during the installation, and it will also be used on the installed system by default. You can change the language for the installed system later, but once you click Continue on this screen, you will not be able to go back and change the language used inside the installer itself.

One language is pre-selected by default on top of the list. If network access is configured at this point (for example, if you booted from a network server instead of local media), the pre-selected language will be determined based on automatic location detection using the GeoIP module. Alternatively, if you used the inst.lang= option on the boot command line or in your PXE server configuration, this language will be selected by default, but you will still be able to change it.

After you select your language and locale, click Continue to confirm your selection and proceed to Installation Summary.

If you are installing a pre-release version of Fedora, a message will be shown after you click Continue warning you about the pre-release status of your installation media. Click I accept my fate to continue with the installation, or Get me out of here to quit the installation and reboot your system.

Resumen de la Instalación

La pantalla Resumen de la Instalación es la localización central para configurar una instalación. A la mayoría de las opciones que pueden ser configuradas durante la instalación se accede desde aquí.

Pantalla Resumen de la Instalación
Figura 3. Resumen de la Instalación

Si usted utiliza una opción Kickstart o una opción de arranque para especificar un repositorio de instalación en una red, pero la red no está disponible al inicio de la instalación, el instalador mostrará la pantalla Configuración de Red para que usted configure una conexión de red antes de mostrar la pantalla Resumen de la Instalación.

La pantalla resumen consta de diversos enlaces a otras pantallas, separadas en categorías. Estos enlaces pueden estar en diversos estados, que se indican gráficamente:

  • Un símbolo de advertencia (triángulo amarillo con una marca de exclamación) cerca de un icono significa que una pantalla requiere su atención antes de iniciar la instalación. Esto normalmente sucede con la pantalla Destino de la Instalación, porque aunque hay una variante de partición automática predeterminada, siempre tiene que, al menos, confirmar esta selección, aunque no desee hacer ningún cambio.

  • Si un enlace está en gris, significa que el instalador está configurando esta sección en este momento y debe esperar a que la configuración termine antes de acceder a esta pantalla. Esto normalmente sucede cuando usted cambia la fuente de instalación en la pantalla Fuente de la Instalación y el instalador está probando la nueva localización de la fuente y obteniendo una lista de los paquetes disponibles.

  • Las pantallas con el texto en negro y sin símbolo de advertencia indican que esa pantalla no requiere su atención. Usted puede cambiar los ajustes de esas pantallas, pero no es necesario que lo haga para completar la instalación. Esto normalmente sucede con los ajustes de ubicación, ya que o bien se ha detectado automáticamente o se ha configurado en la pantalla anterior cuando usted selecciono el idioma y el lugar.

Se muestra un mensaje de advertencia en la parte inferior de la pantalla resumen y el botón Empezar la Instalación está en gris, siempre que al menos un elemento no se haya configurado todavía.

A screenshot of several icons in the Installation Summary screen
Figura 4. Icon States in Installation Summary

Each screen also has an explanatory text below its title, showing settings currently configured in that screen. This text may be concatenated; in that case, move your mouse cursor over it and wait until a tooltip with the full text appears.

An entry in the Installation Summary shows a truncated description and a tooltip with full text.
Figura 5. Tooltip in the Installation Summary

Once you configure everything required for the installation, you can press the Begin Installation button to start installing Fedora. This will take you to Configuration and Installation Progress. Note that as the text below this button says, nothing will be written to your hard drive before you press this button. You can press Quit at any point; this will discard all changes you made in the installer so far and reboot the system.

Date & Time

The Date & Time screen allows you to configure time and date-related settings for your system. This screen is automatically configured based on the settings you selected in Welcome Screen and Language Selection, but you can change your date, time and location settings before you begin the installation.

Screenshot of the Date & Time screen
Figura 6. Date & Time

First, select your Region using the drop-down menu in the top left corner of the screen. Then, select your City, or the city closest to your location in the same time zone. Selecting a specific location helps Fedora ensure that your time is always set correctly including automatic time changes for daylight savings time if applicable.

You can also select a time zone relative to Greenwich Mean Time (GMT) without setting your location to a specific region. To do so, select Etc as your region.

The list of cities and regions comes from the Time Zone Database (tzdata) public domain, which is maintained by the Internet Assigned Numbers Authority (IANA). The Fedora Project can not add cities or regions into this database. You can find more information at the IANA official website.

The switch labeled Network Time in the top right corner of the screen can be used to enable or disable network time synchronization using the Network Time Protocol (NTP). Enabling this option will keep your system time correct as long as the system can access the internet. By default, four NTP pools are configured; you can add others and disable or remove the default ones by clicking the gear wheel button next to the switch.

A dialog window allowing you to add or remove NTP pools from your system configuration
Figura 7. The Add and mark for usage NTP servers dialog

If you disable network time synchronization, the controls at the bottom of the screen will become active, and you will be able to set the current time and date manually.

After configuring your time and date settings, press the Done button in the top left corner to return to Installation Summary.

Keyboard Layout

The Keyboard Layout screen allows you to set up one or more keyboard layouts for your system and a way to switch between them. One keyboard layout is configured automatically based on your selection in Welcome Screen and Language Selection, but you can change this layout and add additional ones before you begin the installation.

Keyboard layouts are a separate setting from system languages, and these two settings can be mixed as you see fit.

All settings configured in this screen will be available on the installed system, and they will also become immediately available inside the installer. You can use the keyboard icon in the top right corner of any screen, or the keyboard switch you configured in this screen, to cycle between your configured layouts.

The keyboard layout configuration screen
Figura 8. Keyboard Layout

The left half of the screen contains a window listing all currently configured layouts. The order in which the layouts are displayed is important - the same order will be used when switching between layouts, and the first listed layout will be the default on your system.

The text field on the right side of the screen can be used to test the currently selected layout.

You can click a layout in the list to highlight it. At the bottom of the list, there is a set of buttons:

  • El botón + añade una nueva distribución. Cuando pulsa este botón se abre una nueva ventana con una lista de las distribuciones disponibles agrupadas por idioma. Puede encontrar una distribución navegando por la lista o puede usar la barra de búsqueda en la parte inferior de esta ventana. Cuando encuentre la distribución que quiere añadir marque y pulse Añadir.

  • El botón - borra el esquema resaltado.

  • Los botones arriba y abajo se pueden usar para mover el esquema resaltado arriba o abajo de la lista.

  • El botón teclado abre una nueva ventana que ofrece una representación visual del esquema resaltado.

Si usa un esquema que no acepta caracteres Latinos, como Rusa, se recomienda agregar también el esquema Inglés (Estados Unidos) y configurar una combinación de tecla para conmutar entre los dos esquemas. Si solo selecciona un esquema sin caracteres Latinos es posible que no puede introducir una contraseña de root y las credenciales de usuario más tarde en el proceso de instalación. Esto puede impedirle completar la instalación.

You can also optionally configure a keyboard switch which can be used to cycle between available layouts. To do so, click the Options button on the right side of the screen. The Layout Switching Options dialog will open, allowing you to configure one or more keys or key combinations for switching. Select one or more key combinations using the check boxes next to them, and click OK to confirm your selection.

Después de terminar de configurar las disposiciones de teclado y cambios, pulse Done en la esquina superior izquierda para volver a Resumen de la Instalación.

Language Support

The Language Support screen allows you to configure language settings for your system. The default language is determined by your selection in Welcome Screen and Language Selection and support for this language can not be removed. You can only add additional languages, which will be available on the installed system - not during the installation.

If you want to change the default language, or the language used during the installation, you must reboot your system, start the installer again, and select a different language in Welcome Screen and Language Selection.

Adding support for another language does not automatically configure the corresponding keyboard layout. Layouts are a separate setting configured in Keyboard Layout.

The language configuration screen. The left side shows that at least one variant of English and French have been selected; the right column shows that French (France) and French (Canada) are selected in the currently highlighted French group.
Figura 9. Language Support

The left panel contains a list of available language groups such as English or Bulgarian. If at least one language from a group is selected, a check mark will be displayed next to the group, and the list entry will be highlighted. This allows you to easily see which languages you have configured support for.

To add support for one or more additional languages, click a group in the left panel, and then select one or more regional variations in the right panel using check boxes next to list entries. Repeat this process for all languages you want to install support for.

Enabling support for some languages (typically languages which use non-Latin script) will install additional packages - for example, enabling support for one or more languages from the Arabic group will also install the arabic-support package group. For more information about packages, see Software Selection.

Once you have made your selections, click Done in the top left corner to return to Installation Summary.

Installation Source

The Installation Source screen allows you to specify a location (local or on the network) from which packages will be downloaded and installed on your system. This screen will be configured automatically in most cases, but you can change your settings or add additional sources.

Normally, when you first enter the Installation Summary screen, the installer will attempt to configure an installation source based on the type of media you used to boot. The full Fedora Server DVD will configure the source as local media, the netinst ISO image will configure the closest network mirror, etc. This process takes some time, especially if the default source is a network mirror. If you plan to use a custom installation source, use the inst.askmethod boot option to skip the initial configuration; this will allow you to enter this screen immediately. See Specifying the Installation Source for information about boot options.

The Installation Source screen
Figura 10. Installation Source

The following options are available. Note that not all of them may be displayed.

Auto-detected installation media

This is the option selected by default if you started the installer from media containing an installation source, such as a live DVD. No additional configuration is necessary. You can click the Verify button check the media integrity.

ISO file

This option will appear if the installation program detected a partitioned hard drive with mountable file systems during boot. Select this option, click the Choose an ISO button, and browse to the installation ISO file’s location on your system. You can click the Verify button to check the file’s integrity.

On the network

Use this option to download packages to be installed from a network location instead of local media. This is the default selection on network installation media.

In most cases, the Closest mirror option available from the protocol selection drop-down menu is preferable. If this option is selected, packages for your system will be downloaded from the most suitable location (mirror).

To manually configure a network-based installation source, use the drop-down menu to specify the protocol to be used when downloading packages. This setting depends on the server you want to use. Then, type the server address (without the protocol) into the address field. If you choose NFS, a second input field will appear where you can specify custom NFS mount options.

When selecting an NFS installation source, you must specify the address with a colon (:) character separating the host name from the path. For example:

server.example.com:/path/to/directory

To configure a proxy for an HTTP or HTTPS source, click the Proxy setup button. Check Enable HTTP proxy and type the URL into the Proxy URL box. If the proxy server requires authentication, check Use Authentication and enter your user name and password. Click OK to finish the configuration.

If your HTTP or HTTPS URL refers to a repository mirror list, mark the check box under the address field.

You can also specify additional repositories in the Additional repositories section to gain access to more installation environments and software add-ons. All environments and add-ons will be available for selection in Software Selection once you finish configuring the sources.

To add a repository, click the + button. To delete a repository, select one in the list and click the - button. Click the arrow icon to revert to the previous list of repositories, i.e. to replace current entries with those that were present at the time you entered the Installation Source screen. To activate or deactivate a repository, click the check box in the Enabled column at each entry in the list.

You can name your additional repository and configure it the same way as the primary repository on the network using the input fields on the right side of the section.

Once you have selected your installation source, click Done in the top left corner to return to Installation Summary.

Selección de Software

La pantalla Selección de Software le permite elegir un Entorno Base y Complementos. Estas opciones controlan qué paquetes software serán instalados en su sistema durante el proceso de instalación.

Esta pantalla está sólo disponible si Fuente de la Instalación está configurada apropiadamente y sólo después de que el instalador haya descargado los metadatos de los paquetes de la fuente.

No es posible seleccionar paquetes específicos durante una instalación manual. Solo puede seleccionar entornos predefinidos y complementos. Si necesita controlar exactamente que paquetes son instalados, debe usar un archivo Kickstart y definir los paquetes en la sección %packages. Vea en Automatizando la Instalación con Kickstart información sobre las instalaciones Kickstart.

La disponibilidad de entornos y complementos depende de su fuente de instalación. De forma predeterminada, la selección depende del medio de instalación que haya usado para el inicio de la instalación; la imagen de instalación Fedora Server tendrá disponibles distintos entornos y complementos para seleccionar que, por ejemplo, la imagen Fedora Cloud. Puede cambiar esto configurando una fuente de instalación diferente que tenga entornos distintos.

La pantalla Selección de Software. En el lado izquierdo
Figura 11. Selección de Software

Para configurar su selección de software, elija primero un entorno en el lado izquierdo de la pantalla. Sólo se puede elegir un entorno, aunque haya más disponibles. Después, en el lado derecho de la pantalla, seleccione uno o más complementos que desee instalar marcando la caja de verificación próxima a cada complemento.

La lista de complementos se divide en dos partes por una línea horizontal. Los complementos por encima de esta línea están definidos como parte del entorno que haya elegido; si selecciona un entorno diferente, los complementos disponibles aquí cambiarán. Los complementos por debajo de la separación no son específicos del entorno que haya elegido.

Los entornos y complementos son definidos usando un archivo comps.xml en su fuente de instalación (por ejemplo, en el directorio repodata/ del DVD de instalación completo Fedora Server). Revise este archivo para ver exactamente que paquetes serán instalados como parte de cierto entorno o complemento. Para más información sobre el archivo comps.xml, vea %packages (requerido) - Selección de paquetes.

Una vez que haya hecho sus selecció de software, pulse Hecho en la esquina superior izquierda para volver a Resumen de la Instalación.

Installation Destination

The Installation Destination screen allows you to configure storage options - namely, which disks will be used as the installation target for your Fedora installation. At least one disk must always be selected for the installation to proceed.

For information about the theory and concepts behind disk partitioning in Linux, see Recommended Partitioning Scheme.

If you plan to use a disk which already contains some data - for example, if you want to shrink an existing Microsoft Windows partition and install Fedora as a second system or if you are upgrading a previous release of Fedora, make sure to back up any important data first. Manipulating partitions always carries a risk - if the process is interrupted or fails for any reason (installer error, hardware failure, power outage, etc.), any data already on the disk may become impossible to recover.

The Installation Destination screen. There are two local standard disks available
Figura 12. Installation Destination

In the top part of the screen, all locally available storage devices (SATA, IDE and SCSI hard drives, USB flash drives, etc.) are displayed in the Local Standard Disks section. Local disks are detected when the installer starts - any storage devices connected after the installation has started will not be shown.

If you need to configure additional local storage devices, select I will configure partitioning and press Done to move to Manual Partitioning. Then, connect any new hard drives you want to make available during the installation, and press the button marked by a circular arrow in the set of controls below the list of mount points on the left side of the screen. In the dialog window that opens, press Rescan Disks and wait until the scanning process completes. Then, press OK to return to Installation Destination; all detected disks including any new ones will be displayed in the Local Standard Disks section.

The Specialized & Network Disks section below shows advanced network storage (such as iSCSI and FCoE disks) currently configured. When you first open this screen, no such devices will be displayed because they can not be automatically detected; to search for network storage devices, press Add a disk button and proceed with Installation Destination - Specialized & Network Disks. Any network storage you configure will then show up in the Specialized & Network Disks the same way local disks are shown above.

All storage devices which will be used to install Fedora have a black circle icon with a white check mark on them. Disks not marked by this icon will not be used during the installation - they will be ignored if you choose automatic partitioning, and they will not be available in manual partitioning.

USB storage devices such as flash drives and external disks will be shown in the Local Standard Disks as well, and they will be available for selection the same way internal hard drives are. Make sure to not select any removable storage as installation targets unless you really want to do so. If you accidentally use a removable drive to install Fedora and then unplug it, your system will likely become unusable.

Disk selection in the Installation Destination screen. Two disks are displayed; only the one on the right side will be used
Figura 13. Unselected and Selected Disk

After you select all disks you want to install Fedora, select one of the two options in the Other Storage Options section:

  • Automatically configure partitioning - If this option is selected, then after you press Done in the top left corner of the screen, the installer will determine the total amount of space on all selected disks, and it will create a Logical Volume Management (LVM) layout suitable for your system. The specifics of this layout depend on whether your system uses BIOS or UEFI firmware, the total amount of free space on your disks, and the amount of RAM on your system (which determines the size of your swap space).

    Con el particionado automático también puede seleccionar la opción de abajo Me gustaría hacer espacio adicional disponible. Use esta opción si desea reclamar espacio de un diseño de particionado existente - por ejemplo, si un disco que desea usar ya contiene un sistema operativo diferente y usted desea hacer estas particiones del sistema más pequeñas para permitir más sitio para Fedora. Se abre el diálogo Reclamar espacio que se describe más adelante en esta sección.

  • I will configure partitioning - Select this option and press Done in the top left corner of the screen to configure your system’s partitioning layout manually. This requires some knowledge of the theory behind disk partitions and related concepts, but gives you full control over the way the system will be installed. For instructions for manual partitioning, see Manual Partitioning.

Additionally, you can select Encrypt my data; this will encrypt all partitions except the ones needed to boot the system (such as /boot) using Linux Unified Key Setup (LUKS). Encrypting your hard drive is recommended. For detailed information about LUKS encryption, see the Fedora Security Guide, available at http://docs.fedoraproject.org/.

Si usted pierde la frase de contraseña LUKS, cualquiera de las particiones encriptadas y los datos en ella llegarán a estar completamente inaccesibles. No hay una forma de recuperar la frase contraseña. Sin embargo, si usted lleva a cabo una instalación Kickstart, usted puede guardar las frases de contraseña cifradas y crear copia de seguridad de las frases de contraseña encriptadas durante la instalación. Vean en Instalacioners Automatizadas con Kickstart información sobre las instalaciones Kickstart.

Para controlar cual de los dispositivos de almacenamiento seleccionados contendrá el gestor de arranque, pulse el enlace Resumen total del disco y gestor de arranque en la esquina inferior izquierda de la pantalla y siga las instrucciones de Instalación del Gestor de Arranque. Tenga en cuenta que mientras en la mayoría de los casos es suficiente con dejar el gestor de arranque en la ubicación predeterminada, algunas configuraciones (por ejemplo, sistemas que requieren una carga de cadena desde otro gestor de arranque) requerirán que el dispositivo de arranque sea especificado manualmente.

Después de que seleccione los dispositivos de almacenamiento, elija entre particionado automático o manual, configure el cifrado y la ubicación del gesrtor de arranque, pulse Hecho en la esquina superior izquierda de la pantalla. Después, dependiendo de sus ajustes, sucederá lo siguiente:

  • Si elije cifrar su disco duro, aparecerá el diálogo Frase de Contraseña de Cifrado del Disco. Introduzca la frase de contraseña elegida en los campos Frase de Contraseña y Confirmar. Cuando lo haya hecho. la frase de contraseña será evaluada y se mostrará su fortaleza junto con sugerencias sobre como hacerla más fuerte si el instalador ha determinado que es débil. Para información sobre contraseñas fuertes vea Fedora Guía de Seguridad.

  • Si ha seleccionado particionado automático y Me gustaría hacer disponible espacio adicional o si no hay suficiente espacio libre en los discos duros seleccionados para instalar Fedora, aparecerá el diálogo Reclamar Espacio. Este diálogo lista todos los dispositivos de disco que ha seleccionado y todas las particiones en esos dispositivos. La esquina inferior derecha del diálogo muestra información sobre cuanto especio necesita el sistema para, al menos, una instalación mínima y cuánto espacio ha reclamado.

    Si usa el diálogo Reclamar Espacio para borrar una partición, se perderán todos los datos de esa partición. Si desea preservar sus datos, use la opción Encojer, no la opción Borrar.

    First, review the displayed list of available storage devices. The Reclaimable Space column shows how much space can be reclaimed from each entry. To reclaim space, select a disk or partition, and press either the Delete button to delete that partition (or all partitions on a selected disk), or Shrink to use free space on a partition while preserving existing data. Alternatively, you can press Delete all in the bottom right corner; this will delete all existing partitions on all disks and make this space available to Fedora, but all existing data on all disks will be lost.

    After you free enough space for your Fedora installation, press Reclaim space to finish.

    No changes to any disks will be made until you press Begin Installation in Installation Summary. The Reclaim Space dialog only marks partitions for resizing or deletion, but no such action is performed immediately.

  • If you selected the I will configure partitioning option, pressing Done will open the Manual Partitioning screen. See Manual Partitioning for further instructions.

Boot Loader Installation

Fedora uses GRUB2 (GRand Unified Bootloader version 2) as its boot loader. The boot loader is the first program that runs when the computer starts and is responsible for loading and transferring control to an operating system. GRUB2 can boot any compatible operating system (including Microsoft Windows) and can also use chain loading to transfer control to other boot loaders for unsupported operating systems.

Installing GRUB2 may overwrite your existing boot loader.

If you have other operating systems already installed, the Fedora installer will attempt to automatically detect and configure the boot loader to start them. You can manually configure any additional operating systems after you finish the installation, if they are not detected properly. For instructions on editing GRUB2 configuration, see the Fedora System Administrator’s Guide, available at http://docs.fedoraproject.org/

If you are installing Fedora system with more than one disk, you may want to manually specify where the bootloader should be installed. Click the Full disk summary and bootloader link at the bottom of the Installation Destination screen. The Selected Disks dialog will appear. The bootloader will be installed on the device of your choice, or on a UEFI system, the EFI system partition will be created on that device during guided partitioning.

The Selected Disks dialog
Figura 14. Boot Device Selection

In the Boot column, a "tick" icon marks one of the devices as the intended boot device. To change the boot device, select a device from the list and click the Set as Boot Device button to install the boot loader there instead. Only one device can be set as the boot device.

To decline installation of a new boot loader, select the device currently marked for boot and click the Do not install bootloader button. This will remove the tick and ensure GRUB2 is not installed on any device.

If you choose not to install a boot loader for any reason, you will not be able to boot the system directly, and you must use another boot method, such as a stand-alone commercial boot loader application. Use this option only if you are sure you have another way to boot your system.

The boot loader may also require a special partition to be created, depending on whether your system uses BIOS or UEFI firmware and also depending on whether the boot drive has a GUID Partition Table (GPT) or a Master Boot Record (MBR, also known as msdos) label. If you use automatic partitioning, the installer will create this partition if needed. For details, see Recommended Partitioning Scheme.

Installation Destination - Specialized & Network Disks

This part of the Installation Destination screen allows you to configure non-local storage devices, namely iSCSI and FCoE storage. This section will mostly be useful to advanced users who have a need for networked disks. For instructions on setting up local hard drives, see Installation Destination.

This section only explains how to make existing network disks available inside the installer. It does not explain how to set up your network or a storage server, only how to connect to them.

A list of currently configured network storage devices
Figura 15. Installation Destination - Network Storage Filters

The screen contains a list of all currently available (discovered) network storage devices. When the screen is opened for the first time, the list will be empty in most cases because no network storage has been discovered - the installer makes no attempt at discovering this unless you configure network disks using a Kickstart file.

To add one or more storage devices to the screen so you can search them and use them in the installation, click Add iSCSI Target or Add FCoE SAN in the bottom right corner of the screen, and follow the instructions in Add iSCSI Target or Add FCoE SAN, depending on which type of network storage you want to add.

Network storage devices successfully discovered and configured by the installer will then be displayed in the main list, along with identifying information such as Name, WWID, Model and Target. To sort the list by a specific column (for example WWID), click the column’s heading.

On lower display resolutions, the list may be too wide to fit on the screen, and some of the columns or buttons may be hidden initially. Use the horizontal scroll bar at the bottom of the list to move your view and see all available table columns and controls.

There are three tabs on the top of the list, which display different information:

Search

Displays all available devices, regardless of their type, and allows you to filter them either by their World Wide Identifier (WWID) or by the port, target, or logical unit number (LUN) at which they are accessed.

Multipath Devices

Storage devices accessible through more than one path, such as through multiple SCSI controllers or Fiber Channel ports on the same system.

The installation program only detects multipath storage devices with serial numbers that are 16 or 32 characters long.

Other SAN Devices

Devices available on a Storage Area Network (SAN).

Depending on the tab you are currently in, you can filter the discovered devices by using the Filter By field. Some of the filtering options are automatically populated based on discovered devices (for example, if you select Filter By: Vendor, another drop-down menu will appear showing all vendors of all discovered devices). Other filters require your input (for example when filtering by WWID), and present you with a text input field instead of a drop-down menu.

In the list (regardless of how it is filtered), each device is presented on a separate row, with a check box to its left. Mark the check box to make the device available during the installation process; this will cause this device (node) to be shown in the Specialized & Network Disks section in Installation Destination. There, you can select the disk as an installation target and proceed with either manual or automatic partitioning.

Devices that you select here are not automatically wiped by the installation process. Selecting a device on this screen does not, in itself, place data stored on the device at risk. Also note that any devices that you do not select here to form part of the installed system can be added to the system after installation by modifying the /etc/fstab file.

When you have selected the storage devices to make available during installation, click Done to return to Installation Destination.

Añadir Objetivo iSCSI

Para usar dispositivos de almacenamiento iSCSI, el instalador debe ser capaz de descubrirlos como objetivos iSCSI y ser capaz de crear una sesión iSCSI para acceder a ellos. Ambos pasos pueden requerir un nombre de usuario y contraseña para autenticación Challenge Handshake Authentication Protocol (CHAP).

También puede configurar un objetivo iSCSI para autenticar el iniciador iSCSI sobre el sistema al que está enganchado el objetivo (CHAP reverso), tanto para el descubrimiento como para la sesión. Usados juntos, CHAP y CHAP reverso se denominan CHAP mutuo o CHAP de dos caminos. CHAP mutuo suministra el mayor nivel de seguridad para conexiones iSCSI, particularmente si el nombre de usuario y la contraseña son diferentes para la autenticación CHAP y para la autenticación CHAP reversa.

Siga el procedimiento de abajo para añadir un objetivo de almacenamiento iSCSI a su sistema.

Añadir Objetivo iSCSI
  1. Pulse el botón Añadir Objetivo iSCSI en la esquina inferior derecha de la pantalla Destino de la Instalación - Discos Especializados y en Red. Se abrirá una nueva ventana de diálogo titulada Añadir Objetivo de Almacenamiento iSCSI.

  2. Introduzca la dirección IP del objetivo iSCSI en el campo Dirección IP Objetivo.

  3. Provide a name in the iSCSI Initiator Name field for the iSCSI initiator in iSCSI Qualified Name (IQN) format. A valid IQN entry contains:

    • The string iqn. (including the period).

    • A date code specifying the year and month in which your organization’s Internet domain or subdomain name was registered, represented as four digits for the year, a dash, and two digits for the month, followed by a period. For example, represent September 2010 as 2010-09.

    • Your organization’s Internet domain or subdomain name, presented in reverse order (with the top-level domain first). For example, represent the subdomain storage.example.com as com.example.storage.

    • A colon (:) followed by a string which uniquely identifies this particular iSCSI initiator within your domain or subdomain. For example, :diskarrays-sn-a8675309

      A complete IQN will therefore look as follows:

      iqn.2010-09.com.example.storage:diskarrays-sn-a8675309

      An example using the correct format is also displayed below the input field for reference.

      For more information about IQNs, see 3.2.6. iSCSI Names in RFC 3720 - Internet Small Computer Systems Interface (iSCSI), available from http://tools.ietf.org/html/rfc3720#section-3.2.6 and 1. iSCSI Names and Addresses in RFC 3721 - Internet Small Computer Systems Interface (iSCSI) Naming and Discovery, available from http://tools.ietf.org/html/rfc3721#section-1.

  4. Specify the type of authentication to use for iSCSI discovery using the Discovery Authentication Type drop-down menu. Depending on which type of authentication you selected, additional input fields (such as CHAP Username and CHAP Password may then become visible. Fill in your authentication credentials; these should be provided by your organization.

  5. Click the Start Discovery button. The installer will now attempt to discover an iSCSI target based on the information you provided, and if the target requires CHAP or reverse CHAP authentication, it will attempt to use the credentials you provided. This process may take some time (generally less than 30 seconds), depending on your network.

    If the discovery was not successful, an error message will be displayed in the dialog window. This message will vary based on which part of the discovery failed. If the installer did not find the target you specified at all, you should check the IP address; if the problem is an authentication error, make sure you entered all CHAP and reverse CHAP credentials correctly and that you have access to the iSCSI target.

    The No nodes discovered error message may also mean that all nodes on the address you specified are already configured. During discovery, Anaconda ignores nodes which have already been added.

    If the discovery was successful, you will see a list of all discovered nodes.

  6. Select one or more nodes you want to log in to by marking or unmarking the check box next to each node discovered on the target. Below the list, select again the type of authentication you want to use; you can also select the Use the credentials from discovery option if the CHAP/reverse CHAP user name and password you used to discover the target are also valid for logging in to it.

    After selecting all nodes you want to use, click Log In to initiate an iSCSI session. Anaconda will attempt to log in to all selected nodes. If the login process is succesful, the Add iSCSI Storage Target dialog will close, and all nodes you have configured will now be shown in the list of network disks in Installation Destination - Specialized & Network Disks.

You can repeat this procedure to discover additional iSCSI targets, or to add more nodes from a previously configured target. However, note that once you click the Start Discovery button for the first time, you will not be able to change the iSCSI Initiator Name. If you made an error when configuring the initiator name, you must restart the installation.

Add FCoE SAN

The following procedure explains how to add Fibre Channel over Ethernet (FCoE) storage devices and make them available during the installation:

Add FCoE Target
  1. Click the Add FCoE SAN button in the bottom right corner of Installation Destination - Specialized & Network Disks. A new dialog window will open.

  2. Select the network interface (NIC) which is connected to your FCoE switch from the drop-down menu. Note that this network interface must be configured and connected - see Network & Hostname.

  3. Below the NIC drop-down menu are two choices:

    Use DCB

    Data Center Bridging (DCB) is a set of enhancements to the Ethernet protocols designed to increase the efficiency of Ethernet connections in storage networks and clusters. This option should only be enabled for network interfaces that require a host-based DCBX client. Configurations on interfaces that implement a hardware DCBX client should leave this check box empty.

    Use auto vlan

    This option indicates whether VLAN discovery should be performed. If this box is checked, then the FCoE Initiation Protocol (FIP) VLAN discovery protocol will run on the Ethernet interface once the link configuration has been validated. If they are not already configured, network interfaces for any discovered FCoE VLANs will be automatically created and FCoE instances will be created on the VLAN interfaces. This option is enabled by default.

  4. After you select which interface and options to use, click Add FCoE Disk(s). Discovered FCoE storage devices will be displayed under the Other SAN Devices tab in Installation Destination - Specialized & Network Disks.

Manual Partitioning

The Manual Partitioning screen allows you to create a storage configuration for your Fedora system manually, giving you a greater control over your system’s storage.

In most other installers for both Linux and other operating systems, disk partitioning usually takes a "bottom-up" approach. In these installers, you first create underlying devices such as LVM physical volumes, then you create a layout such as LVM on top of them, then you create file systems on top of logical volumes, and the last step is usually assigning a mount point to each volume as needed.

Anaconda uses an opposite approach. First, you create all separate mount points you need, and everything needed to create them (creating a volume group, logical volumes inside it, and physical volumes where the volume group will reside) is performed automatically. You can then adjust the automatic settings as you require.

No permanent changes will be made to your disks during the actual partitioning process. The configuration you have selected will only be written to your system after you press the Begin installation button in Installation Summary.

The Manual Partitioning screen. At this point
Figura 16. Manual Partitioning

When you first open the Manual Partitioning screen, the column on the left side will display all previously existing partitions on all drives which you selected as installation targers in Installation Destination. If none of the selected drives contain any existing partitions, then a message informing you that no mount points currently exist will appear.

Here, you can choose a partitioning scheme such as LVM or BTRFS and click the Click here to create them automatically to prompt the installer to create a basic partitioning layout; this layout follows the guidelines described in Recommended Partitioning Scheme. The created layout is a basic layout where partition/volume sizes are determined automatically based on the total amount of available space.

Click the + button to add a mount point. In the dialog window that opens, choose a mount point such as / or /home, and the desired capacity for the mount point (such as 10GB or 500MB). Note that specifying the mount point is mandatory, but you do not have to specify the capacity at this point; this is useful when adding a mount point which you want to make larger than the current available space permits. Then, click Add mount point to add it to the list using the default settings, which means it will be created as a logical volume, and a new volume group will be created for it unless one already exists.

Then, select the newly created mount point in the list on the left side. A set of controls will display on the right side of the screen, allowing you to change its mount point, the device on which it will physically reside, its capacity, file system, etc. When you change any settings, press Update Settings on the bottom right. This will save the adjusted configuration; you can now create another mount point, or select a different existing one and adjust its settings as well.

For a description of available device and file system types, see Device, File System and RAID Types.

To remove a mount point, select it in the list and press the - button below.

The exact steps for configuring your storage depend on your specific needs and your system configuration. Procedures for creating specific layouts are described further in this chapter. Before you start, you should also review Recommended Partitioning Scheme and Advice on Partitions for a list of requirements and tips for partitioning your disks for Fedora.

Below the list of existing mount points are two fields, showing you how much free space is left on your storage devices and how much total space they have.

Click the X storage devices selected to view a summary of currently selected storage devices; this may help you with orientation in more complicated storage schemas. Devices displayed here are the ones you have selected in Installation Destination. If you want to add or remove any storage devices from your configuration, return to that screen and change your selection.

You can press the Reset All button in the bottom right corner at any time to reset the storage configuration to the state it was in when you last opened the Manual Partitioning screen. This means that if you modify the storage configuration, leave the screen, and then come back, the Reset button will reset the configuration back to the already modified state, discarding only the changes you have made recently, not all changes to the storage configuration since you booted the installer.

To discard all changes, and to also detect any new drives which have not been detected when the installer started (usually when you attached a new drive after you started), press the button marked by a circular arrow in the set of controls below the list of mount points on the left side of the screen. In the dialog window that opens, press Rescan Disks and wait until the scanning process completes. Then, press OK to return to Installation Destination; all detected disks including any new ones will be displayed in the Local Standard Disks section.

The Rescan Disks dialog
Figura 17. Rescan Disks

After you finish configuring your system storage, press Done in the top left corner to save the configuration and return to the Installation Summary screen. At this point, the installer will check if your storage configuration is valid. If an error was detected, a message will be displayed at the bottom of the screen. Click the message to open a dialog window explaining what kind of error has been detected (for example, you put /boot on a Btrfs subvolume, or you did not create a BIOS Boot partition when your system requires one).

If such a message is displayed, go back and fix any issues found by the installer; otherwise you will not be able to proceed with the installation. You can also press Done again to return to the Installation Summary anyway, but a storage configuration error will prevent you from starting the actual installation process.

If no error message is displayed and if you made any changes since the last time you have visited this screen, a summary dialog will appear, displaying a detailed list of the changes you made. Review the list and click Accept Changes to proceed with Installation Summary, or click Cancel & Return to Custom Partitioning if you want to make any more changes.

Creating Standard Partitions

Standard partitions are the most common type of partition, with the widest support across operating systems. For example, Microsoft Windows uses exclusively physical partitions and can not natively work with LVM or Btrfs. Most Fedora partitioning setups will also require at least one standard partition for the /boot directory, and possibly also another standard partition with the BIOS Boot or EFI System file system to store the boot loader.

See An Introduction to Disk Partitions for additional information about the concepts behind physical partitions.

The Manual Partitioning screen
Figura 18. Create Standard Partition

Follow the procedure below to create mount points on standard physical partitions:

Creating Standard Partitions
  1. Click the + button at the bottom of the list showing existing mount points. A new dialog window will open.

  2. In the new dialog window, specify a mount point for which you want to create a separate mount point - for example, /. Optionally, specify a size for the partition using standard units such as MB or GB (for example, 50GB). Then, click Add mount point to add the mount point and return to the main partitioning screen.

    When creating a swap partition, specify the mount point as swap. For a BIOS Boot partition, use biosboot. For an EFI System Partition, use /boot/efi.

    For information about these partition types, see Recommended Partitioning Scheme.

  3. The mount point has now been created using the default settings, which means it has been created as an LVM logical volume. Select the newly created mount point in the left pane to configure it further, and convert it to a physical partition by changing the Device Type option to Standard Partition. Then, click Update Settings in the bottom right corner of the screen.

  4. In the Device(s) section on the right side of the screen, you can see that the partition has been assigned to one or more hard drives. Click the Modify button to configure on which drive this partition will be created.

  5. In the Configure Mount Point dialog, you can specify which physical devices (disks) this volume may reside on. You can select one or more disks which will be used to hold this volume by holding down Ctrl and clicking each disk in the list. If you select multiple disks here, Anaconda will determine where exactly the partition should be created based on how you configured the rest of the installation. If you want to make sure that this partition is placed on a specific hard drive, select only that drive and unselect all others.

    After you finish configuring the partition’s location, click Save to return to the main Manual Partitioning screen.

  6. Configure other settings specific to the partition - its Mount Point, Desired Capacity, and File System. Press Update Settings to apply any changes to the configuration.

Repeat this procedure for any additional standard partitions you want to create.

Creating Software RAID

Redundant arrays of independent disks (RAIDs) are constructed from multiple storage devices that are arranged to provide increased performance and, in some configurations, greater fault tolerance. See Device, File System and RAID Types a description of different kinds of RAIDs.

A RAID device is created in one step, and disks are added or removed as necessary. One RAID partition per physical disk is allowed for each device, so the number of disks available to the installation program determines which levels of RAID device are available to you. For example, if your system has two hard drives, the installation program will not allow you to create a RAID10 device, which requires 4 separate partitions.

This section only explains how to create software RAID with standard (physical) partitions. However, you can also configure LVM volume groups and Btrfs volumes to use RAID and place their logical volumes or Btrfs subvolumes on top of this RAID array. See Creating a Logical Volume Managament (LVM) Layout and Creating a Btrfs Layout for instructions on creating RAID in LVM and Btrfs.

The Manual Partitioning screen
Figura 19. Create Software RAID

RAID configuration options are only visible if you have selected two or more disks for installation. At least two disks are required to create a RAID device, and some RAID layouts will require more. Requirements for different types of RAID are described in Device, File System and RAID Types.

Follow the procedure below to create software RAID:

Creating Software RAID
  1. Click the + button at the bottom of the list showing existing mount points. A new dialog window will open.

  2. In the new dialog window, specify a mount point for which you want to create a separate software RAID partition - for example, /. Optionally, specify a size for the new partition using standard units such as MB or GB (for example, 50GB). Then, click Add mount point to add the mount point and return to the main partitioning screen.

    When creating a mount point for swap on software RAID, specify the mount point as swap.

  3. The mount point has now been created using the default settings, which means it has been created as an LVM logical volume. Select the newly created mount point in the left pane to configure it further, and convert it to a software RAID partition by changing the Device Type option to RAID.

  4. Choose a RAID type from the RAID Level drop-down menu. Available RAID types and their requirements are described in Device, File System and RAID Types.

  5. In the Device(s) section on the right side of the screen, you can see that the partition has been assigned to several physical disks. Click the Modify button to configure on which drives this partition will be created.

  6. In the Configure Mount Point dialog, you can specify which physical devices (disks) this partition may reside on. You can select one or more disks which will be used to hold this partition by holding down Ctrl and clicking each disk in the list. If you want to make sure that this partition is placed on a specific set of hard drives, select only those drives and unselect all others.

    After you finish configuring the partition’s location, click Save to return to the main Manual Partitioning screen.

  7. Configure other settings specific to the partition - its Mount Point, Desired Capacity, and File System. Press Update Settings to apply any changes to the configuration.

Repeat this procedure for any additional standard partitions with software RAID you want to create.

Creating a Logical Volume Managament (LVM) Layout

Logical Volume Management (LVM) presents a simple logical view of underlying physical storage space, such as hard drives or LUNs. Partitions on physical storage are represented as physical volumes that can be grouped together into volume groups. Each volume group can be divided into multiple logical volumes, each of which is analogous to a standard disk partition. Therefore, LVM logical volumes function as partitions which can span multiple physical disks.

See Understanding LVM for additional information about the concepts behind Logical Volume Management.

Some partition types - notably the /boot directory and the BIOS Boot and EFI partitions - can not be placed on logical volumes. Use standard physical volumes for them. See Recommended Partitioning Scheme for more information.

The Manual Partitioning screen
Figura 20. Create LVM Logical Volume

Follow the procedure below to create LVM logical volumes and volume groups.

Creating LVM Logical Volumes and Groups
  1. Click the + button at the bottom of the list showing existing mount points. A new dialog window will open.

  2. In the new dialog window, specify a mount point for which you want to create a separate logical volume - for example, /. Optionally, specify a size for the volume using standard units such as MB or GB (for example, 50GB). Then, click Add mount point to add the volume and return to the main partitioning screen.

    When creating a mount point for swap on LVM, specify the mount point as swap.

  3. The mount point has now been created using the default settings, which means it has been created as an LVM logical volume, and a volume group has been created to contain it. Select the newly created mount point in the left pane to configure it further. If you want to use thin provisioning for this volume, change the Device Type option to LVM Thin Provisioning.

  4. In the Volume Group menu, you can see that the volume has been assigned to an automatically created volume group, which is named after the Fedora variant you are installing (for example, fedora-server. Click the Modify button under the drop-down menu to access the volume group settings.

  5. In the Configure Volume Group dialog, you can change the volume group’s name, its RAID level (see Device, File System and RAID Types for information about available RAID types), and you can also specify which physical devices (disks) this volume group should reside on. You can select one or more disks which will be used to hold this volume group by holding down Ctrl and clicking each disk in the list.

    If you select a redundant RAID type (such as RAID1 (Redundancy)), the volume group will take up twice its actual size on your disks. A 5 GB volume group with RAID1 will take up 10 GB of space.

    You can also make sure that the volume group is encrypted by selecting the Encrypt option; this will enable LUKS encryption for the entire volume group. See the Fedora Security Guide, available at http://docs.fedoraproject.org/, for information about LUKS disk encryption.

    Additionally, you can set a fixed size for the volume group by selecting the Fixed option from the Size policy menu and entering a size for the volume group.

    After you finish configuring the volume group settings, click Save to return to the main Manual Partitioning screen.

    The configuration dialog does not allow you to specify the size of the volume group’s physical extents. The size will always be set to the default value of 4 MiB. If you want to create a volume group with different physical extents, create it manually by switching to an interactive shell and using the vgcreate command, or use a Kickstart file with the volgroup --pesize=size command.

  6. If you need to create more than one volume group, open the Volume Group drop-down menu and select the Create a new volume group option. A new dialog window will open, identical to the one described in the previous step. Again, select a name, storage devices, encryption settings, RAID level and size policy for the new group, and click Save. The new volume group will then become available in the Volume Group drop-down menu; you can then go through your existing mount points and change this setting to assign them to a different volume group.

  7. Configure other settings specific to the logical volume - its Mount Point, Desired Capacity, File System, and Name. Press Update Settings to apply any changes to the configuration.

Repeat this procedure for any additional logical volumes you want to create. Note that when creating additional LVM logical volumes, a new volume group is not automatically created each time; instead, any additional volumes are assigned to an existing group.

For each mount point you create, review its settings and make sure that it is assigned to the correct group, that it has sufficient capacity, and that it has a descriptive name so you can identify the volume later if you need to.

Creating a Btrfs Layout

Btrfs is a type of file system, but it has several features characteristic of a storage device. It is designed to make the file system tolerant of errors, and to facilitate the detection and repair of errors when they occur. It uses checksums to ensure the validity of data and metadata, and maintains snapshots of the file system that can be used for backup or repair.

Creating a Btrfs layout is somewhat similar to LVM (described in Creating a Logical Volume Managament (LVM) Layout) with slightly different terminology. A Btrfs volume is the equivalent of an LVM volume group, and a Btrfs subvolume is similar to a LVM logical volume. An important difference to note is how Anaconda reports sizes for separate mount points: For LVM, the exact size of each logical volume is shown next to each mount point in the left pane, while with Btrfs, the total size of the entire volume is shown next to each subvolume.

Some partition types - notably the /boot and /usr directories and the BIOS Boot and EFI partitions - can not be placed on Btrfs subvolumes. Use standard physical volumes for them (or an LVM logical volume for /usr). See Recommended Partitioning Scheme for more information.

The Manual Partitioning screen
Figura 21. Create Btrfs Subvolume

Follow the procedure below to create Btrfs volumes and subvolumes:

Creating Btrfs Subvolumes and Volumes
  1. Click the + button at the bottom of the list showing existing mount points. A new dialog window will open.

  2. In the new dialog window, specify a mount point for which you want to create a separate logical volume - for example, /. Optionally, specify a size for the volume using standard units such as MB or GB (for example, 50GB). Then, click Add mount point to add the volume and return to the main partitioning screen.

    When creating a mount point for swap on Btrfs, specify the mount point as swap.

  3. The mount point has now been created using the default settings, which means it has been created as an LVM logical volume. Select the newly created mount point in the left pane to configure it further, and convert it to a Btrfs subvolume by changing the Device Type option to Btrfs. Then, click Update Settings in the bottom right corner of the screen.

  4. In the Volume menu, you can see that the subvolume has been assigned to an automatically created volume, which is named after the Fedora variant you are installing (for example, fedora-server00. Click the Modify button under the drop-down menu to access the volume settings.

  5. In the Configure Volume dialog, you can change the volume’s name, its RAID level (see Device, File System and RAID Types for information about available RAID types), and you can also specify which physical devices (disks) this volume should reside on. You can select one or more disks which will be used to hold this volume by holding down Ctrl and clicking each disk in the list.

    If you select a redundant RAID type (such as RAID1 (Redundancy)), the volume will take up twice its actual size on your disks. A 5 GB volume with RAID1 will take up 10 GB of space.

    You can also make sure that the volume is encrypted by selecting the Encrypt option; this will enable LUKS encryption for the entire volume. See the Fedora Security Guide, available at http://docs.fedoraproject.org/, for information about LUKS disk encryption.

    Additionally, you can set a fixed size for the volume by selecting the Fixed option from the Size policy menu and entering a size for the volume group.

    After you finish configuring the Btrfs volume settings, click Save to return to the main Manual Partitioning screen.

  6. If you need to create more than one Btrfs volume, open the Volume drop-down menu and select the Create a new volume group option. A new dialog window will open, identical to the one described in the previous step. Again, select a name, storage devices, encryption settings, RAID level and size policy for the new volume, and click Save. The new volume will then become available in the Volume Group drop-down menu; you can then go through your existing mount points and change this setting to assign them to a different volume.

  7. Configure other settings specific to the subvolume - its Mount Point, Desired Capacity, File System, and Name. Press Update Settings to apply any changes to the configuration.

Repeat this procedure for any additional Btrfs subvolumes you want to create. Note that when creating additional subvolumes, a new volume is not automatically created each time; instead, any additional subvolumes are assigned to an existing volume.

For each mount point you create, review its settings and make sure that it is assigned to the correct volume, that it has sufficient capacity, and that it has a descriptive name so you can identify the subvolume later if you need to.

Device, File System and RAID Types

Fedora supports multiple types of devices and file systems. The lists below offer a short description of each available device, file system and RAID type and notes on their usage.

To select a device type or a file system of a partition or a logical volume, select it in the list in Manual Partitioning and select a Device Type and a File System from their respective drop-down menus on the right side of the screen. Then, click Update Settings and repeat this process for all mount points you want to modify.

To configure software RAID, make sure that you have enough physical hard drives selected as installation targets (the number of separate drives required for each type of RAID is noted in its description). Then, choose a RAID level when creating or modifying a Btrfs volume or LVM volume group, or select Software RAID as the device type to create software RAID with standard partitions. For detailed instructions, see Creating a Btrfs Layout, Creating a Logical Volume Managament (LVM) Layout, and Creating Software RAID as needed.

Device Types
  • Standard Partition - A standard partition can contain a file system or swap space. Standard partitions are most commonly used for /boot and the BIOS Boot and EFI System partitions. LVM logical volumes or Btrfs subvolumes are recommended for most other uses. See An Introduction to Disk Partitions for additional information about the concepts behind physical partitions.

  • LVM - Choosing LVM as the Device Type creates an LVM logical volume and a volume group to contain it (unless one already exists, in which case the new volume is assigned to the existing group). LVM can improve performance when using physical disks and allows you to use multiple disks for a single mount point. For information on how to create a logical volume, see Creating a Logical Volume Managament (LVM) Layout. Also see Understanding LVM for some additional information about LVM in general.

  • LVM Thin Provisioning - Using thin provisioning, you can manage a storage pool of free space, known as a thin pool, which can be allocated to an arbitrary number of devices when needed by applications. The thin pool can be expanded dynamically when needed for cost-effective allocation of storage space.

  • RAID - Creating two or more software RAID partitions allows you to create a software RAID device. One RAID partition is assigned to each disk on the system. See Creating Software RAID for instructions on creating software RAID.

  • BTRFS - Btrfs is a file system with several device-like features. It is capable of addressing and managing more files, larger files, and larger volumes than the ext2, ext3, and ext4 file systems. See Creating a Btrfs Layout for more information about creating Btrfs volumes.

File Systems
  • ext4 - The ext4 file system is based on the ext3 file system and features a number of improvements. These include support for larger file systems and larger files, faster and more efficient allocation of disk space, no limit on the number of subdirectories within a directory, faster file system checking, and more robust journaling. Ext4 is the default and recommended file system used by Fedora Workstation and Cloud. The maximum supported size of a single ext4 file system is 50 TB.

  • ext3 - The ext3 file system is based on the ext2 file system and has one main advantage - journaling. Using a journaling file system reduces time spent recovering a file system after a crash, as there is no need to check the file system for metadata consistency by running the fsck utility every time a crash occurs.

  • ext2 - An ext2 file system supports standard Unix file types, including regular files, directories, or symbolic links. It provides the ability to assign long file names, up to 255 characters.

  • swap - Swap partitions are used to support virtual memory. In other words, data is written to a swap partition when there is not enough RAM to store the data your system is processing. A swap partition should always be created; see Recommended Partitioning Scheme for details such as the recommended size.

  • xfs - XFS is a highly scalable, high-performance file system that supports file systems up to 16 exabytes (approximately 16 million terabytes), files up to 8 exabytes (approximately 8 million terabytes), and directory structures containing tens of millions of entries. XFS also supports metadata journaling, which facilitates quicker crash recovery. The maximum supported size of a single XFS file system is 500 TB. Starting with Fedora 22, XFS is the default and recommended file system on Fedora Server.

    Note that the size of an XFS file system can not currently be reduced without destroying and recreating the file system. If you expect that you will need to adjust the sizes of your file systems often, using XFS is not recommended, as it makes administration substantially more time-consuming.

  • vfat - The VFAT file system is a Linux file system that is compatible with Microsoft Windows long file names on the FAT file system.

  • BIOS Boot - A very small partition required for booting from a device with a GUID partition table (GPT) on BIOS systems and UEFI systems in BIOS compatibility mode. See Recommended Partitioning Scheme for details.

  • EFI System Partition - A small partition required for booting a device with a GUID partition table (GPT) on a UEFI system. See Recommended Partitioning Scheme for details.

Software RAID Types
  • RAID0 (Performance) - Distributes data across multiple disks. Level 0 RAID offers increased performance over standard partitions and can be used to pool the storage of multiple disks into one large virtual device. Note that Level 0 RAIDs offer no redundancy and that the failure of one device in the array destroys data in the entire array. RAID 0 requires at least two disks.

  • RAID1 (Redundancy) - Mirrors all data from one partition onto one or more other disks. Additional devices in the array provide increasing levels of redundancy. RAID 1 requires at least two disks.

  • RAID4 (Error Checking) - Distributes data across multiple disks and uses one disk in the array to store parity information which safeguards the array in case any disk within the array fails. Because all parity information is stored on one disk, access to this disk creates a "bottleneck" in the array’s performance. Level 4 RAID requires at least three disks.

  • RAID5 (Distributed Error Checking) - Distributes data and parity information across multiple disks. Level 5 RAIDs therefore offer the performance advantages of distributing data across multiple disks, but do not share the performance bottleneck of level 4 RAIDs because the parity information is also distributed through the array. RAID 5 requires at least three disks.

  • RAID6 (Redundant Error Checking) - Level 6 RAIDs are similar to level 5 RAIDs, but instead of storing only one set of parity data, they store two sets. RAID 6 requires at least four disks.

  • RAID10 (Performance, Redundancy) - Level 10 RAIDs are nested RAIDs or hybrid RAIDs. They are constructed by distributing data over mirrored sets of disks. For example, a level 10 RAID array constructed from four RAID partitions consists of two mirrored pairs of striped partitions. RAID 10 requires at least four disks.

In most cases, at least the following mount points should always be created:

/boot - 500 MB

This partition contains the operating system kernel, which allows Fedora to boot. It also contains other files used during the bootstrap process. Due to the limitations of most firmware, creating a separate, small standard partition for this directory is recommended. In most scenarios, a 500 MB /boot partition is adequate.

If your system has a hardware RAID controller, be aware that some BIOS types do not support booting from it. In that case, the /boot partition must be created on a partition outside of the RAID array, such as on a separate hard drive.

Also note that the /boot directory can not be placed on a LVM logical volume or a Btrfs subvolume. Use a standard partition.

/ (root) - 10 GB

This is where the root directory is located. The root directory is the top level of the directory structure. By default, all files are written to this partition unless a different partition is mounted in the path being written to (for example, /boot or /home). If you follow the recommended scheme described in this section, this will be the partition where most software packages will be installed.

For a minimal installation, a 5 GB root partition will be sufficient. However, for most common installations which include extra packages and a graphical user interface, the root partition should be at least 10 GB; with 20 GB being sufficient for most common use cases.

The / mount point is the top of the Linux Filesystem Hierarchy, and is referred to as the root file system, or root. The /root directory, sometimes pronounced "slash-root", is the home directory for the root user.

/home - at least 10 GB

To store user data separately from system data, create a dedicated mount point for the /home directory. This partition should be sized based on the amount of data that will be stored locally, number of users, and so on. This will allow you to upgrade or reinstall Fedora without erasing user data files. During the installation, a separate /home partition will be created if there are 50 GB or more free space for your Fedora installation.

When using Fedora as a workstation for normal use with a graphical environment, this mount point should have the most disk space assigned to it, as it will likely hold the most data (user settings, images, videos, etc).

swap - based on your system parameters

Swap partitions support virtual memory; data is written to them when there is not enough RAM to store the data your system is processing. This partition’s size is a function of system memory workload, not total system memory, and therefore is not equal to the total system memory size. Therefore, it is important to analyze what applications a system will be running and the load those applications will serve in order to determine the system memory workload. Application providers and developers should be able to provide some guidance.

When the system runs out of swap space, the kernel terminates processes as the system RAM memory is exhausted. Configuring too much swap space results in storage devices being allocated but idle and is a poor use of resources. Too much swap space can also hide memory leaks. The maximum size for a swap partition and other additional information can be found in the mkswap(8) man page.

The table below provides the recommended size of a swap partition depending on the amount of RAM in your system and whether you want sufficient memory for your system to hibernate. If you let the installation program partition your system automatically, the swap partition size will be established using these guidelines. Automatic partitioning setup assumes hibernation is not in use, and the maximum size of the swap partition is limited to 10% of the total size of the hard drive. If you want to set up enough swap space to allow for hibernation, or if you want to set the swap partition size to more than 10% of the system’s storage space, you must edit the partitioning layout manually.

Table 2. Recommended System Swap Space
Amount of RAM in the system Recommended swap space Recommended swap space if allowing for hibernation

2 times the amount of RAM

8 GB - 64 GB

0.5 times the amount of RAM

hibernation not recommended

At the border between each range listed above (for example, a system with 2 GB, 8 GB, or 64 GB of system RAM), discretion can be exercised with regard to chosen swap space and hibernation support. If your system resources allow for it, increasing the swap space may lead to better performance.

Distributing swap space over multiple storage devices - particularly on systems with fast drives, controllers and interfaces - also improves swap space performance.

BIOS Boot (1 MB) or EFI System Partition (200 MB)

The GRUB2 boot loader can be installed either in the Master Boot Record (MBR) or the GUID Partition Table (GPT) of the boot device. In order to determine which of these methods to use, the installation program considers the following variations:

Systems with BIOS firmware and UEFI systems in BIOS compatibility mode

If the disk is already formatted, the partitioning scheme is retained. If the disk is not formatted, or you have erased all existing partitions from the disk, the installer will choose the following:

  • MBR if the size of the disk is less than 2 TB (terabytes)

  • GPT if the size of the disk is more than 2 TB

    You can force the installer to use GPT on disks smaller than 2 TB by using the inst.gpt boot option as described in Boot Options. However, the opposite is not possible - you can not use MBR on disks larger than 2 TB.

    You need to create a BIOS Boot partition with a size of 1 MB to install on a system with BIOS firmware if the disk containing the boot loader uses GPT. If the disk uses a MBR, no special partition is necessary on a BIOS system.

Systems with UEFI firmware

Only GPT is allowed on UEFI systems. In order to install on a formatted disk with a MBR, it must be reformated and relabeled. All data currently on the disk will be lost.

UEFI-based systems require an EFI System Partition at least 50 MB in size (recommended size is 200 MB), regardless of the partitioning scheme.

If your system requires either a BIOS Boot partition or an EFI System Partition based on the requirements detailed above, this partition must be created as a standard physical partition. It can not reside on an LVM volume or a Btrfs subvolume.

Also note that if your system does not require any of these partitions, they will not be shown in the File System menu in mount point options.

Many systems have more partitions than the minimum listed above. Choose partitions based on your particular needs. See Advice on Partitions for additional information and advice.

Only assign storage capacity to those partitions you require immediately. You may allocate free space at any time, to meet needs as they occur.

If you are not sure how best to configure the partitions for your computer, accept the automatic default partition layout provided by the installation program as described in Installation Destination.

Advice on Partitions

There is no best way to partition every system; the optimal setup depends on how you plan to use the system being installed. However, the following tips may help you find the optimal layout for your needs:

  • Consider encrypting any partitions and volumes which might contain sensitive data. Encryption prevents unauthorized people from accessing the data on the partitions, even if they have access to the physical storage device. In most cases, you should at least encrypt the /home partition, which contains user data.

  • In some cases, creating separate mount points for directories other than /, /boot and /home may be useful; for example, on a server running a MySQL database, having a separate mount point for /var/lib/mysql will allow you to preserve the database during a reinstallation without having to restore it from backup afterwards. However, having unnecessary separate mount points will make storage administration more difficult.

  • Some special restrictions apply to certain directories with regards on which partitioning layouts can they be placed. Notably, the /boot directory must always be on a physical partition (not on an LVM volume or a Btrfs subvolume), and /usr can not be on a Btrfs subvolume.

  • If you are new to Linux, consider reviewing the Linux Filesystem Hierarchy Standard at http://refspecs.linuxfoundation.org/FHS_2.3/fhs-2.3.html for information about various system directories and their contents.

  • Each kernel installed on your system requires approximately 20 MB on the /boot partition. The default partition size of 500 MB for /boot should suffice for most common uses; increase the size of this partition if you plan to keep many kernels installed at the same time.

  • The /var directory holds content for a number of applications, including the Apache web server, and is used by the DNF package manager to temporarily store downloaded package updates. Make sure that the partition or volume containing /var has at least 3 GB.

  • The contents of the /var directory usually change very often. This may cause problems with older solid state drives (SSDs), as they can handle a lower number of read/write cycles before becoming unusable. If your system root is on an SSD, consider creating a separate mount point for /var on a classic (platter) HDD.

  • The /usr directory holds the majority of software on a typical Fedora installation. The partition or volume containing this directory should therefore be at least 5 GB for minimal installations, and at least 10 GB for installations with a graphical environment.

  • If /usr or /var is partitioned separately from the rest of the root volume, the boot process becomes much more complex because these directories contain boot-critical components. In some situations, such as when these directories are placed on an iSCSI drive or an FCoE location, the system may either be unable to boot, or it may hang with a Device is busy error when powering off or rebooting.

    This limitation only applies to /usr or /var, not to directories below them. For example, a separate partition for /var/www will work without issues.

  • Consider leaving a portion of the space in an LVM volume group unallocated. This unallocated space gives you flexibility if your space requirements change but you do not wish to remove data from other volumes. You can also select the Thin provisioning device type for the partition to have the unused space handled automatically by the volume.

  • The size of an XFS file system can not be reduced - if you need to make a partition or volume with this file system smaller, you must back up your data, destroy the file system, and create a new, smaller one in its place. Therefore, if you expect needing to manipulate your partitioning layout later, you should use the ext4 file system instead.

  • Use Logical Volume Management (LVM) if you anticipate expanding your storage by adding more hard drives after the installation. With LVM, you can create physical volumes on the new drives, and then assign them to any volume group and logical volume as you see fit - for example, you can easily expand your system’s /home (or any other directory residing on a logical volume).

  • Creating a BIOS Boot partition or an EFI System Partition may be necessary, depending on your system’s firmware, boot drive size, and boot drive disk label. See Recommended Partitioning Scheme for information about these partitions. Note that the graphical installer will not let you create a BIOS Boot or EFI System Partition if your system does not require one - in that case, they will be hidden from the menu.

  • If you need to make any changes to your storage configuration after the installation, Fedora repositories offer several different tools which can help you do this. If you prefer a command line tool, try system-storage-manager.

Kdump

This screen is disabled by default. To enable it during the installation, you must use the inst.kdump_addon=on option at the boot menu. See Advanced Installation Options for details, and The Boot Menu for instructions on using custom boot options.

Use this screen to select whether or not Kdump will be activated on the installed system, and how much memory will be reserved for it if enabled.

The Kdump configuration screen
Figura 22. Kdump

Kdump is a kernel crash dumping mechanism which, in the event of a system crash, captures the contents of the system memory at the moment of failure. This captured memory can then be analyzed to find the cause of the crash. If Kdump is enabled, it must have a small portion of the system’s memory (RAM) reserved to itself. This reserved memory will not be accessible to the main kernel.

To enable Kdump on the installed system, check Enabled. Then, select either Automatic or Manual memory reservation settings, and if you selected Manual, enter the amount of memory to be reserved in megabytes into the Memory to be reserved field.

The amount of memory which you should reserve is determined based on your system’s architecture (AMD64 and Intel 64 will have different requirements than IBM Power, for example) as well as the total amount of system memory. In most cases, automatic reservation will be satisfactory. If you insist on manual settings, see the Red Hat Enterprise Linux 7 Kernel Crash Dump Guide for guidelines. This document also contains more in-depth information about how Kdump works, how to configure additional settings, and how to analyze a saved crash dump.

The Usable System Memory readout below the reservation input field shows how much memory will be accessible to your main system once your selected amount of RAM is reserved.

Additional settings, such as the location where kernel crash dumps will be saved, can only be configured after the installation using either the system-config-kdump graphical interface, or manually in the /etc/kdump.conf configuration file.

Después de configurar los ajustes de Kdump settings, pulse Hecho en la esquina superior izquierda para volver a Resumen de la Instalación.

Red y Nombre de Equipo

The Network & Hostname screen is used to configure network interfaces. Options selected here will be available both during the installation (if needed for tasks such as downloading packages from a remote location) and on the installed system.

Network configuration is an expansive topic and many of the options available during the installation are beyond the scope of this document. For detailed information about networking, including both theoretical topics and specific instructions and examples, see the Fedora Networking Guide, available at http://docs.fedoraproject.org/.

The Network & Hostname screen. In the left pane
Figura 23. Red y Nombre de Equipo

Locally accessible interfaces are automatically detected by the installation program and cannot be manually added or deleted. All detected interfaces are listed on the left side of the screen. Click an interface in the list to display its current configuration (such as IP and DNS address); the details are displayed on the right side of the screen.

Below the list of interfaces are two buttons. Use the + button to add a virtual network interface (Team, Bond or VLAN) as described in Adding a Virtual Network Interface. To remove a previously created virtual interface, select it in the list and click the - button.

To change settings such as IP addresses, DNS servers, or routing configuration for an existing interface (both virtual and physical), select the interface in the left pane and click Configure in the bottom right corner of the screen. Available settings are described in Editing Network Interface Configuration.

Use the ON/OFF switch in the top right corner to enable or disable the currently selected interface.

Below the list of connections, enter a host name for this computer in the Hostname input field. The host name can be either a fully-qualified domain name (FQDN) in the format hostname.domainname, or a short host name with no domain name. Many networks have a Dynamic Host Configuration Protocol (DHCP) service that automatically supplies connected systems with a domain name; to allow the DHCP service to assign the domain name to this machine, only specify the short host name.

Adding a Virtual Network Interface

Para añadir una interfaz de red virtual, pulse el botón + en la parte inferior de la lista de interfaces. Se abrirá una nueva ventana, solicitando que seleccione uno de los tres tipos disponibles de interfaces virtuales:

  • Vínculo - Vinculando NIC (Controlador de Interfaz de Red), un método para unir múltiples interfaces de red físicos junto en un único canal vinculado.

  • Equipo - Equipando NIC, una nueva implementación para agregar enlaces, diseñado para suministrar un pequeño kernel controlador para implementar un manejo más rápido de los flujos de paquetes y diversas aplicaciones para hacer todo lo demás en el espacio de usuario.

  • Vlan (Virtual LAN) - Un método para crear múltiples dominios de difusión distintos que están mutuamente aislados.

Select the interface type you want to add, and click Add. Another dialog window will open, allowing you to edit any available settings for your chosen interface type. For information about available settings, see the respective sections of the Fedora Networking Guide, available at https://docs.fedoraproject.org/. Basic documentation is also available in Editing Network Interface Configuration.

To access the settings dialog again after you closed it, select the same interface in the list of configured interfaces and click Configure in the bottom right corner of the screen. To remove a virtual interface, select it in the list and click the - button below.

Editing Network Interface Configuration

This section only details the most important settings for a typical wired connection used during installation. Many of the available options do not have to be changed in most installation scenarios and are not carried over to the installed system. Configuration of other types of networks is broadly similar, although the specific configuration parameters may be different. To learn more about network configuration after installation, see the Fedora Networking Guide, available at http://docs.fedoraproject.org/.

To configure a network connection manually, select that connection in the list on the left side of the screen, and click the Configure button. A dialog will appear that allows you to configure the selected connection. The configuration options presented depends on the connection type - the available options will be slightly different depending on whether it is a physical interface (wired or wireless network interface controller) or a virtual interface (Bond, Team or Vlan) which you previously configured in Adding a Virtual Network Interface.. A full description of all configuration settings for all connection types is beyond the scope of this document; see the Networking Guide for details.

The most common and useful options in the configuration dialog are:

Enable or disable the connection by default

In the General tab of the configuration dialog, you can select or unselect the Automatically connect to this network when it is available check box to allow or disallow this connection to connect by default. When enabled on a wired connection, this means the system will typically connect during startup (unless you unplug the network cable); on a wireless connection, it means that the interface will attempt to connect to any known wireless networks in range.

Additionally, you can allow or disallow all users on the system from connecting to this network using the All users may connect to this network option. If you disable this option, only root will be able to connect to this network.

It is not possible to only allow a specific user other than root to use this interface, because no other users are created at this point during the installation. If you need a connection for a different user, you must configure it after the installation.

Set up static IPv4 or IPv6 settings

By default, both IPv4 and IPv6 are set to automatic configuration depending on current network settings. This means that addresses such as the local IP address, DNS address, and other settings will be detected automatically each time the interface connects to a network. In many cases, this is sufficient, but you can also provide static configuration in the IPv4 Settings and IPv6 Settings, respectively.

To set static network configuration, navigate to one of the settings tabs and select a method other than Automatic (for example, Manual) from the Method drop-down menu. This will enable the Addresses field below.

In the IPv6 Settings tab, you can also set the method to Ignore to disable IPv6 on this interface.

Then, click Add on the right side and add a set of settings: Address, Netmask (for IPv4), Prefix (for IPv6), and Gateway.

The DNS servers field accepts one or more IP addresses of DNS servers - for example, 10.0.0.1,10.0.0.8.

The final option in both tabs is Require IPvX addressing for this connection to complete. Select this option in the IPv4 tab to only allow this connection if IPv4 was successful; the same principle applies to this setting in the IPv6 tab. If this option remains disabled for both IPv4 and IPv6, the interface will be able to connect if configuration succeeds on either IP protocol.

Configure routes

In the IPv4 Settings and IPv4 Settings tabs, click the Routes button in the bottom right corner to configure routing settings for a specific IP protocol on an interface. A new dialog will open, allowing you to Add a specific route.

If you confire at least one static route, you can disallow all routes not specifically configured here by enabling the Ignore automatically obtained routes.

Select Use this connection only for resources on its network to prevent this connection from becoming the default route. This option can be selected even if you did not configure any static routes. Enabling this option means that this route will only be used when necessary to access certain resources, such as intranet pages which require a local or VPN connection. Another (default) route will be used for publicly available resources if possible. Note that unlike the additional routes configured in this dialog, this setting will be transferred to the installed system. Also note that this option is only useful when more than one interface is configured.

When you finish configuring the interface’s routing settings, click OK to return to the configuration dialog.

Once you finish configuring the interface, click Save in the configuration window’s bottom right corner to save your settings and return to Network & Hostname.

Configuration and Installation Progress

The Configuration screen is displayed after you finish configuring all required items in Installation Summary and press the Begin installation button. After this point, the installation process actually starts and changes are being made to your selected disks. It is not possible to go back to the Installation Summary and change any settings configured there; if you need to do so, you must wait for the installation process to finish, reboot your system, log in and change your settings on the installed system.

The Configuration screen. Two more screens at the top require configuration. Installation progress is displayed at the bottom.
Figura 24. Configuration and Installation Progress

In the top part of the screen, two additional options are available, allowing you to configure authentication settings - the root password and an additional user account. Configuring the root password is required to finish the installation; creating a user account can be skipped. If you do so, you will be prompted to create a non-root user account after the installation finishes and your system reboots.

The bottom of the screen shows a progress bar and a message informing you of the current progress of the installation. When the installation finishes and the root password has been set, you can press the Finish configuration button to reboot your computer and log in to your newly installed Fedora system.

Before you finish the installation and reboot, either remove the media (CD, DVD or a USB drive) which you used to start the installation, or make sure that your system tries to boot from the hard drive before trying removable media. Otherwise, your computer will start the installer again instead of the installed system.

Contraseña del usuario root

La pantalla Contraseña de Root se usa para configurar la contraseña de root para su sistema. Esta contraseña será usada para acceder como cuenta de administrador (también conocido como superusuario), que se usa para tareas de administración del sistema como la instalación y actualización de paquetes de software y los cambios de configuración en todo el sistema como los ajustes de red y cortafuegos, las opciones de almacenamiento y la adicción o modificación usuarios, grupos y permisos de archivos.

Durante la instalación siempre se creará la cuenta root. Sin embargo, siempre se debería crear también una cuenta de usuario normal en Crear Usuario y usar esta cuenta para acceder al sistema. Utilice solo la cuenta de administrador cuando necesite llevar a cabo tareas que requieran acceso de administrador.

La cuenta root tiene control completo sobre el sistema. Si un usuario no autorizado obtiene acceso a esta cuenta, puede acceder o borrar todos los archivos personales de los usuarios o de lo contrario explotar la máquina para sus propios nefastos propósitos. Vea la Fedora Guía de Seguridad, disponible en https://docs.fedoraproject.org/, para documentación detallada sobre la seguridad de la cuenta y directrices para elegir una contraseña fuerte.

Pantalla Contraseña de Root. Use los campos de entrada texto para suministrar su contraseña de root.
Figura 25. Contraseña del usuario root

Una vez que haya elegido una contraseña fuerte, introduzcala en el campo Contraseña de Root. Los caracteres que escriba se mostrarán como puntos por seguridad. Después, teclee la misma contraseña en el campo Confirmar para asegurar que la ha introducido correctamente. Ambas contraseñas tecleadas debe ser la misma.

Según introduzca la contraseña será evaluada y el instalador determinará su fortaleza. Si el instalador considera que la contraseña es débil aparecerá un mensaje en la parte inferior de la pantalla, explicando que aspecto de la contraseña que ha elegido es considerado insuficiente. Por ejemplo:

The password you have provided is weak: The password is shorter than 5 characters.

If a message similar to the above appears, it is highly recommended to choose a different, stronger password.

Once you configure the superuser password, click Done in the top left corner to return to Configuration and Installation Progress. If you selected a weak password, you must press the button twice.

Create User

The Create User screen can be used to create and configure one normal (non-root) user account during the installation. Only one user account can be configured here; if you require more accounts, wait until the installation completes, reboot your system and then create other accounts using either the useradd command in a terminal, or a graphical utility for managing user accounts (for example, the Users screen in the Settings menu in GNOME).

Creating a normal user account is not required to finish the installation; however, it is highly recommended. If you do not create one, you will have to log in to the system as root directly, which is not recommended.

The Create screen. Use the text input fields to create a user account and configure its settings.
Figura 26. Create User

To configure a user account, fill out the Full name (for example, John Smith) and Username (for example, jsmith). The username will used to log in from a command line; if you install a graphical environment, then your graphical login manager will use Full name.

Make sure that the Require a password to use this account check box is enabled, enter a password you want to use for this account into the Password field. The characters you write will be displayed as dots for security. Then, repeat the same password in the Confirm password field below to ensure you entered it properly. Both entered passwords must be the same.

Según introduzca la contraseña será evaluada y el instalador determinará su fortaleza. Si el instalador considera que la contraseña es débil aparecerá un mensaje en la parte inferior de la pantalla, explicando que aspecto de la contraseña que ha elegido es considerado insuficiente. Por ejemplo:

The password you have provided is weak: The password is shorter than 5 characters.

If a message similar to the above appears, it is highly recommended to choose a different, stronger password.

The Make this user administrator check box gives the user you are creatng administrative rights (by adding this user into the wheel group), allowing this user to use the sudo command to perform tasks normally only available to root using only the user password, instead of the root password. This may be more convenient, but can also pose a security risk.

If you give administrator privileges to an user, make sure that the account is protected by a strong password. Never give an user administrator privileges without requiring any password for the account.

See the Fedora Security Guide, available at the http://docs.fedoraproject.org/, for detailed information about password security including guidelines for selecting strong passwords.

To additional settings, click the Advanced button below the password input fields. A new dialog window titled Advanced User Configuration will open. This dialog is described in the following section.

Advanced User Configuration

The Advanced User Configuration dialog allows you to change the following settings for the new user account.

Advanced settings for the new user account.
Figura 27. Advanced User Configuration
  • The user’s Home directory (/home/username by default).

  • The user’s ID (UID). The default value is 1000. UIDs 0-999 are reserved by the system so they can not be assigned to an user.

  • The the group ID (GID) of the user’s default group. The default group name will be the same as the user name, and its default GID is 1000. GIDs 0-999 are reserved by the system so they can not be assigned to an user’s group.

  • The user’s group membership. The user account you are creating will always have one default group membership (the user’s default group with an ID set in the Specify a group ID manually field). In the Group Membership field, you can specify additional groups as a comma-separated list. Groups which do not already exist will be created; you can specify custom GIDs for them in parentheses. If you do not specify a custom GID for a new group, it will be assigned automatically.
