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.
Pre-Flight Check
  • 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. For a refresher on editing files with vim see: New User Tutorial: Overview of the Vim Text Editor vim /etc/yum.repos.d/MariaDB10.repo # 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!
Stop MariaDB: systemctl stop mariadb Remove the existing MariaDB packages: yum -y remove mariadb-server mariadb mariadb-libs Clean-up the repository cache information with the following command: yum clean all
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 Run mysql_upgrade: mysql_upgrade Verify MySQL is now MariaDB by using the command client:
mysql
