5.1. Preparing for a Network Installation

Note

Make sure no installation DVD (or any other type of DVD or CD) is in your system's CD or DVD drive if you are performing a network-based installation. Having a DVD or CD in the drive might cause unexpected errors.
CD、DVD、又はフラッシュドライブのような USB ストレージデバイス上に ブートメディアを持っていることを確認します。
The Fedora installation medium must be available for either a network installation (via NFS, FTP, or HTTP) or installation via local storage. Use the following steps if you are performing an NFS, FTP, or HTTP installation.
The NFS, FTP, or HTTP server to be used for installation over the network must be a separate, network-accessible server. It must provide the complete contents of the installation DVD-ROM.

Note

The Fedora installation program has the ability to test the integrity of the installation media. It works with the CD, DVD, hard drive ISO, and NFS ISO installation methods. We recommend that you test all installation media before starting the installation process, and before reporting any installation-related bugs (many of the bugs reported are actually due to improperly-burned discs). To use this test, type the following command at the boot: prompt:
linux mediacheck

Note

The public directory used to access the installation files over FTP, NFS, or HTTP is mapped to local storage on the network server. For example, the local directory /var/www/inst/Fedora16 on the network server can be accessed as http://network.server.com/inst/Fedora16.
In the following examples, the directory on the installation staging server that will contain the installation files will be specified as /location/of/disk/space. The directory that will be made publicly available via FTP, NFS, or HTTP will be specified as /publicly_available_directory. For example, /location/of/disk/space may be a directory you create called /var/isos. /publicly_available_directory might be /var/www/html/Fedora16, for an HTTP install.
以下では ISO イメージ が必要になります。ISO イメージとは、 DVD の内容の完全なコピーを収納しているファイルです。DVD から ISO イメージを 作成するには以下のコマンドを使用します:
dd if=/dev/dvd of=/path_to_image/name_of_image.iso
where dvd is your DVD drive device, name_of_image is the name you give to the give to the resulting ISO image file, and path_to_image is the path to the location on your system where the resulting ISO image will be stored.
インストール DVD からファイルを、インストールステージングサーバーとして動作する Linux インスタンスにコピーするには、「Preparing for FTP and HTTP installation」 か、又は 「NFS インストールの準備」 で継続します。

5.1.1. Preparing for FTP and HTTP installation

Extract the files from the ISO image of the installation DVD and place them in a directory that is shared over FTP or HTTP.
次に、ディレクトリが FTP か HTTP 経由で共有されていることを確認して、クライアントアクセスを確認します。このディレクトリがサーバー自身からアクセス可能であり、そしてインストール先の同じサブネット上の別のマシンからアクセス可能であることもチェックします。

5.1.2. NFS インストールの準備

For NFS installation it is not necessary to extract all the files from the ISO image. It is sufficient to make the ISO image available on the network server via NFS.
  1. ISO イメージを NFS のエキスポートディレクトリに転送します。Linux システムでは以下を実行します:
    mv /path_to_image/name_of_image.iso /publicly_available_directory/
    where path_to_image is the path to the ISO image file, name_of_image is the name of the ISO image file, and publicly_available_directory is a directory that is available over NFS or that you intend to make available over NFS.
  2. SHA256 checksum プログラムを使用して、コピーした ISO イメージが完全かどうか確認します。 多くの SHA256 checksum プログラムが各種オペレーティングシステム用に入手できます。 Linux システムでは以下を実行します:
    $ sha256sum name_of_image.iso
    where name_of_image is the name of the ISO image file. The SHA256 checksum program displays a string of 64 characters called a hash. Compare this hash to the hash displayed for this particular image on the GPG Keys page on the Fedora Project site at http://fedoraproject.org/en/keys. The two hashes should be identical.
  3. Ensure that an entry for the publicly available directory exists in the /etc/exports file on the network server so that the directory is available via NFS.
    ディレクトリを読み込み専用で特定のシステムにエキスポートするには:
    /publicly_available_directory client.ip.address (ro)
    ディレクトリを読み込み専用で全てのシステムにエキスポートするには:
    /publicly_available_directory * (ro)
  4. On the network server, start the NFS daemon (on a Fedora system, use /sbin/service nfs start). If NFS is already running, reload the configuration file (on a Fedora system use /sbin/service nfs reload).
  5. Be sure to test the NFS share following the directions in the Fedora Deployment Guide. Refer to your NFS documentation for details on starting and stopping the NFS server.

Note

The Fedora installation program has the ability to test the integrity of the installation media. It works with the CD, DVD, hard drive ISO, and NFS ISO installation methods. We recommend that you test all installation media before starting the installation process, and before reporting any installation-related bugs (many of the bugs reported are actually due to improperly-burned discs). To use this test, type the following command at the boot: prompt:
