Uninstalling MariaDB is as easy as installing MariaDB. If you ever want to uninstall and roll back to stock MySQL, continue reading for a step-by-step guide to uninstall MariaDB.

Here are the steps to Uninstall MariaDB and return to stock MySQL.

 

Find and Uninstall MariaDB

cp -Rf /var/lib/mysql /var/lib/mysql-old
mv /etc/my.cnf /etc/my.cnf-old
rpm -qa |grep -i mariadb

The above command will list the MariaDB installations and you can use either rpm -e command or yum to uninstall those RPMs

Enable cPanel native MySQL support

/usr/local/cpanel/scripts/update_local_rpm_versions --edit target_settings.MySQL50 uninstalled

/usr/local/cpanel/scripts/update_local_rpm_versions –edit target_settings.MySQL51 uninstalled /usr/local/cpanel/scripts/update_local_rpm_versions –edit target_settings.MySQL55 installed

Install MySQL 5.5

/usr/local/cpanel/scripts/check_cpanel_rpms --fix --targets=MySQL50,MySQL51,MySQL55

This should install MySQL 5.5 on your server. You may want to run a check and repair database if any is reporting an issue in your log file.

After that, you will need to rebuild PHP so that it will use the new libmysqlclient.
