The proper upgrade path from MySQL 5.1 to MariaDB 10.0 is as follows:
1. MySQL 5.1
2. MariaDB 5.5
3. MariaDB 10.0
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
Then disable the MariaDB 5.5 repo:
mv /etc/yum.repos.d/MariaDB55.repo /etc/yum.repos.d/MariaDB55.repo.disabled
Now find which repo you should use with the MariaDB repository generator. We’re going to add the CentOS 6 (64 bit) MariaDB 10.0 repository.
# MariaDB 10.0 CentOS repository list – created 2014-10-10 17:33 UTC
name = MariaDB
baseurl = http://yum.mariadb.org/10.0/centos6-amd64
Then exit and save the file with the command :wq .
Step #3: Add the EPEL Repository
MariaDB may have dependencies such as socat that are apart of Extra Packages for Enterprise Linux (EPEL), which is a community repository of non-standard packages for the RHEL distribution. To install the EPEL repository:
rpm -iUvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
service mysql stop
Remove the existing MariaDB packages:
yum -y remove mysql-server mysql-client
Clean-up the repository cache information with the following command:
yum clean all
Step #5: 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:
service mysql start
Be sure that MariaDB is set to start at boot:
chkconfig mysql on
Verify MySQL is now MariaDB by using the command client:
