How To Install MySQL Database Server on CentOS

Install MySQL Database Server on CentOS

In this tutorial, we will show you how to install MySQL Database Server on CentOS. For those of you who didn’t know, MySQL is a relational database management system (RDBMS) that runs as a server providing multi-user access to a number of databases. The MySQL source code is freely available because it was originally developed as freeware. MySQL is written in C and C++ and is compatible with all major operating systems. MySQL can be used for a variety of applications but is most commonly found on Web servers.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MySQL Database Server on a CentOS server.

Prerequisites

  • A server running one of the following operating systems: CentOS Linux.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install MySQL Database Server on CentOS

First, you must add the Remi yum repository information corresponding to your CentOS/RHEL version to yum:

For CentOS 6.x use:

#rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
#rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

 For CentOS 5.x use:

#rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
#rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-5.rpm

After installing the Remi repository on your system, then look for MySQL’s latest version using –enablerepo=remi switch option.

#yum --enablerepo=remi list mysql mysql-server

Sample output:
