How To Upgrade The Mysql To Percona on WHM/cPanel Server.!

Imp: Please take backup of database and mysql config file my.cnf

cp -Rf /var/lib/mysql /var/lib/mysql-old
mv /etc/my.cnf /etc/my.cnf-old

Check the Mysql version:

mysql -V
mysql Ver 14.12 Distrib 5.0.77, for redhat-linux-gnu (x86_64)

We need to Disable the Mysql in cPanel:

/scripts/update_local_rpm_versions --edit target_settings.MySQL51 uninstalled

The following script will remove the mysql from your server.

/scripts/check_cpanel_rpms --fix --targets=MySQL51
