How to migrate your Database from MySQL to OpenSource MariaDB

mariadb

MariaDB is a community-developed fork of the MySQL intended to remain free under the GNU GPL. It is led by the original developers of MySQL, who forked it due to concerns over its acquisition by Oracle.

So what is the difference  between MySQl and MariaDB?

Well besides  the fact that it is completely opensourced, It also supports a number of Storage Engines including Percona’s famous Xtradb.

How do I migrate from MySQL to MariaDB?

It is not that difficult to migrate since mariadb uses almost the same source code.

The below steps are for Red Hat, Centos and Fedora for Ubuntu or Debian please use apt-get.

First we need to take a backup of our MySQL Database with the following command

mysqldump -u root -p --all-databases > mysqlbackup.sql

Then backup our my.cnf file

cp -a /etc/my.cnf my.bak

Now stop mysql server and remove mysql install

service mysqld stop

yum remove mysql mysql-server mysql-libs

Now you need atomic repo or mariadb repo 

I prefer atomic so as it has the latest php software as well

wget -q -O - http://www.atomicorp.com/installers/atomic | sh


yum install mariadb-server

This will install the client and libraries with the one command.

Copy the my.bak to mariadb conf file.

cp my.bak /etc/my.cnf

service mysqld start
mysql -u root -p -Be 'show databases'
enter password

Should show you all the databases. I also had my Replication up an running which was great.

Update: Incase you get a mysql-libs error as follows

Error: mariadb-libs conflicts with mysql-libs

Then uninstall mysql-libs with the yum command below and then try installing again.

yum remove mysql-lib

Please ensure you be careful while doing this and this post assumes you know what you are doing and take full responsibility for the same
