MariaDB is a drop-in replacement for MySQL installed by default on CentOS 7, and offers many speed and performance improvements. MariaDB offers more storage engines than MySQL, including Cassandra (NoSQL), XtraDB (drop-in replacement for InnoDB), and OQGRAPH.
- These instructions are intended for upgrading from MariaDB 5.5 to MariaDB 10.0 on Fedora 20.
- I’ll be working from a Liquid Web Self Managed Fedora 20 server, and I’ll be logged in as root.
Step #1: Add the MariaDB Repository
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 7 (64 bit) MariaDB 10.0 repository.

# MariaDB 10.0 CentOS repository list – created 2014-10-13 13:04 UTC # http://mariadb.org/mariadb/repositories/ [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.0/fedora20-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
Then exit and save the file with the command :wq.
Step #2: Remove the Existing MariaDB Installation
Be sure to backup MariaDB before proceeding with the following instructions!
systemctl stop mariadb
Remove the existing MariaDB packages.
yum -y remove mariadb-server mariadb mariadb-libs
Step #3: Install MariaDB 10.0
At this point, installing MariaDB 10.0 is as simple as running just one command.
yum -y install MariaDB-server MariaDB-client
And then start MariaDB again.
systemctl start mysql
Be sure that MariaDB is set to start at boot.
systemctl enable mysql
Verify MySQL is now MariaDB by using the command client.
