How to replace MySQL with MariaDB in cpanel

September 30th, 2014 Leave a comment Go to comments

Backup existing MySQL data

Make sure to save all existing data just in case there are any issues.

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

Disable the targets so cPanel no longer handles MySQL updates

The following will mark the versions of MySQL we distribute as uninstalled so they are no longer maintained by cPanel/WHM

/scripts/update_local_rpm_versions –edit target_settings.MySQL50 uninstalled
/scripts/update_local_rpm_versions –edit target_settings.MySQL51 uninstalled
/scripts/update_local_rpm_versions –edit target_settings.MySQL55 uninstalled

Remove existing MySQL RPM’s so theres a clean slate for MariaDB

The below command will uninstall the MySQL RPM’s!

/scripts/check_cpanel_rpms –fix –targets=MySQL50,MySQL51,MySQL55

Create a yum repository for MariaDB

vi /etc/yum.repos.d/MariaDB.repo

place the following inside of it depending on the DISTRO (https://downloads.mariadb.org/mariadb/repositories/):

[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/5.5.29/centos6-amd64/
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

Remove php from the /etc/yum.conf file then run the following commands

yum install MariaDB-server MariaDB-client MariaDB-devel
/etc/init.d/mysql start
mysql_upgrade
/etc/init.d/mysql restart

Add php back to the /etc/yum.conf file to ensure future php updates don’t get clobbered

Rebuild easyapache/php to ensure modules are intact/working

/scripts/easyapache –build
