Installing MariaDB on CentOS

I am trying to install MariaDB on a CentOS system 2.6.32-358.el6.x86-64 which comes with MYsql installed.

As root I have run

yum install MariaDB-server MariaDB-client

After the Resolving Dependencies section it comes up with the error

Error: mysql conflicts with MariaDB-server-5.5.33a-1.x86_64

and exits.

Could you advise how to overcome this problem.

With thanks

Hi,

As far as I can see, CentOS comes with MySQL 5.1, so you would most likely have a similar problem upgrading to MySQL 5.5 as well.

You need to remove older MySQL packages first, e.g. to run 

sudo yum remove mysql-server mysql

(and whichever else mysql* packages cause the conflict), and then install MariaDB server as you already did.

Don't forget to backup your data before the upgrade, it is always the good practice.
