How To Install MariaDB 5.5 on CentOS 6
MariaDB is a drop-in replacement for MySQL. It is easy to install, offers many speed and performance improvements, easy to integrate into most MySQL deployments. Answers for compatibility questions can be found at: MariaDB versus MySQL – Compatibility. MariaDB offers more storage than MySQL, including Cassandra (NoSQL), XtraDB (drop-in replacement for InnoDB), and OQGRAPH.
- These instructions are intended for installing MariaDB on a single CentOS 6 node.
- I’ll be working from a Liquid Web Core Managed CentOS 6.5 server, and I’ll be logged in as root.
First, you’ll follow a simple best practice: ensuring the list of available packages is up to date before installing anything new:
yum -y update
Now find which repo you should use with the MariaDB repository generator. We’re going to add the CentOS 6 (64 bit) MariaDB 5.5 repository.

name = MariaDB
baseurl = http://yum.mariadb.org/5.5/centos6-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
Then exit and save the file with the command :wq .
Stop MySQL:
service mysqld stop
Remove the existing MySQL packages:
yum -y remove mysql-server mysql
At this point, installing MariaDB is as simple as running just one command:
yum -y install mysql-server mysql
And then start MySQL, now MariaDB, again:
service mysql start
Run mysql_upgrade:
mysql_upgrade
Verify MySQL is now MariaDB by using the command client:
mysql
