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
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/centos7-amd64
Then exit and save the file with the command :wq .
Step #2: Remove the Existing MariaDB Installation
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
Verify MySQL is now MariaDB by using the command client:
Welcome to the MariaDB monitor. Commands end with ; or \g.
