MariaDB is “An enhanced, drop-in replacement for MySQL”. Below you will find some steps on how to affectively stop cPanel/WHM from maintaining MySQL and begin utilizing MariaDB for any and all database activity on your server but please note that, cPanel/WHM no longer maintains MySQL on your system it is on the Systems Administrator to manage and maintain any updates and maintenance on the database software. We recommend only experienced systems administrators perform the above and we are not responsible for any possible data loss.
Step 1: 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
## Also please take sql file of the existing databases, so that we can avoid the data lose
Step 2: Disable the targets so cPanel no longer handles MySQL updates #ONLY FOR cPanel 11.36+
The following will mark the versions of MySQL we distribute as uninstalled so they are no longer maintained by cPanel/WHM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
Step 3: Remove existing MySQL RPM’s so theres a clean slate for MariaDB
/scripts/check_cpanel_rpms --fix --targets=MySQL50,MySQL51,MySQL55
[20130623.211100]
[20130623.211100] The following RPMs are unneeded on your system and should be uninstalled:
[20130623.211100] MySQL55-client.5.5.31-1.cp1136
[20130623.211100] MySQL55-devel.5.5.31-1.cp1136
[20130623.211100] MySQL55-server.5.5.31-1.cp1136
[20130623.211100] MySQL55-shared.5.5.31-1.cp1136
[20130623.211100] MySQL55-test.5.5.31-1.cp1136
0
[20130623.211100] Removing 0 broken rpms:
[20130623.211100] rpm: no packages given for erase
[20130623.211100] No new RPMS needed for install
[20130623.211100] Uninstalling unneeded rpms: MySQL55-test MySQL55-server MySQL55-client MySQL55-shared MySQL55-devel
Step 4: Create a yum repository for MariaDB
access https://downloads.mariadb.org/mariadb/repositories and select the DISTRO and place the repo content to /etc/yum.repos.d/MariaDB.repo EX (In my cause): #vi /etc/yum.repos.d/MariaDB.repo # MariaDB 5.5 CentOS repository list - created 2013-06-23 21:13 UTC # http://mariadb.org/mariadb/repositories/ [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/5.5/centos6-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=
Step 5: install MariaDB using the following command
yum install MariaDB-server MariaDB-client MariaDB-devel ##If you are having any dependency problem, please remove php from the /etc/yum.conf file and then run yum command again. Please add it back to yum conf once the package is installed. /etc/init.d/mysql start mysql_upgrade /etc/init.d/mysql restart
Final Step: Rebuild easyapache/php to ensure modules are intact/working
/scripts/easyapache --build
