Install MariaDB 10 on CentOS 6


At the time of writing, MariaDB 10.1 is the development version of MariaDB. It is based on MariaDB 5.5, and includes back-ported features from MySQL 5.6. There are also new features that are exclusive to MariaDB.

For CentOS, RedHat, and Fedora, it is highly recommended to install from a repository using yum. This guide will walk you through the installation steps for CentOS 6.

Add the MariaDB repository

First, ensure the list of available packages is up-to-date before installing. Open your SSH terminal and input the following commands.

yum -y update

Add the MariaDB repository.

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

For 32-bit users, paste the following text:

[mariadb]name = MariaDBbaseurl = http://yum.mariadb.org/10.1/centos6-x86gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDBgpgcheck=1

For 64-bit users, paste the following text:

[mariadb]name = MariaDBbaseurl = http://yum.mariadb.org/10.1/centos6-amd64gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDBgpgcheck=1

Save the MariaDB.repo file.

Install software

At this point, installing MariaDB is as simple as running just one command.

yum install MariaDB-server MariaDB-client -y

Once the installation completes, start MariaDB.

service mysql start

Next, set MariaDB to start on every boot.

chkconfig mysql on
