4.3. Removing Software with yum

To remove software, yum examines your system for both the specified software, and any software which claims it as a dependency. The transaction to remove the software deletes both the software and the dependencies.
To remove the tsclient package from your system, use the command:
su -c 'yum remove tsclient'
Enter the password for the root account when prompted.
To remove all of the packages in the package group MySQL Database, enter the command:
su -c 'yum groupremove "MySQL Database"'
Enter the password for the root account when prompted.

Data and Configuration File Retention

The removal process leaves user data in place but may remove configuration files in some cases. If a package removal does not include the configuration file, and you reinstall the package later, it may reuse the old configuration file.
