Uninstall Percona Server for MySQL

To completely uninstall Percona Server for MySQL, remove all the installed packages and data files.

  1. Stop the Percona Server for MySQL service:

    $ sudo systemctl stop mysql
  2. As a superuser, either root or using sudo, use yum and the remove option. You can use the remove option to remove a specific package or a group of packages. In the example, the command removes all packages starting with percona-server.

    $ sudo yum remove percona-server*
  3. The first command removes the /var/lib/mysql directory and everything within it. The second command removes the /etc/my.cnf file, the main configuration file for Percona Server for MySQL.


    This step removes all the packages and deletes all the data files (databases, tables, logs, and other files). Take a backup before doing this in case you need the data.

    $ rm -rf /var/lib/mysql
    $ rm -f /etc/my.cnf
