In this tutorial we will learn, how to install MySQL Server 5.6 on CentOS 7 / RHEL 7 . In our previous post, we have installed MySQL Server 5.6 on CentOS 6.x/RHEL 7.x.
In CentOS 7/ RHEL 7 , now MariaDB is introduced as a defualt database. Still many Organisations/Company would like to continue with MySQL. Whereas System Admin who earlier worked on MySQL can easily work on MariaDB. MariaDB is a community-developed fork of the MySQL relational database management system.
MariaDB’s lead developer is Michael “Monty” Widenius, the founder of MySQL and Monty Program AB. He had previously sold his company, MySQL AB, to Sun Microsystems for US$1 billion. MariaDB is named after Monty’s younger daughter, Maria. (Reference taken from Wikipedia)

easy to to follow instructions, thanks, they helped me a lot
thanks a lot, i now installed mysql 5.6.
Amazing work dear Sharad. I am so grateful for your perfect instructions that are fool proof. In fact I had to clean mariadb 5.5 from centos 7 and also a 56 version i had first. If anyone tries when earlier versions are there they may have errors like many comments here.
Each previous install of mysql should be uninstalled and then reinstall. My suggestion is that you could add in your article if someone has another ver of mysql they may like to uninstall first after saving their current databases if any, I did on a new setup so it did work without any error. Thanks and appreciations for your good work. Thanks.
Thank you very much, it helps me a lot.
This is a great tutorial. However, I have a server with Plesk 12.5 and Centos 7 that installed the default MariaDB. I need to use the native Mysql 5.6. So my question is how do I replace mariadb with mysql 5.6 or if I follow the steps above, how does plesk see the mysql database server as localhost/default.
I do not want to do a complete reinstall of Plesk and the server.
Thanks
John
