How To Install And Secure MariaDB on CentOS 7

If we are loyal XAMPP users, since October 2015 there have been major changes that have taken place. Where the default database in the XAMPP bundle has changed from MySQL to MariaDB. Actually it’s not only XAMPP that has changed, but there are many client tools that come to use MariaDB as the default database. MariaDB replaced MySQL as the default database system in the CentOS 7 repositories. At this time, we will discuss how to install and secure MariaDB on CentOS 7.

MariaDB was created by one of MySQL’s original developers in 2009 after MySQL was acquired by Oracle during the Sun Microsystems merger. Today MariaDB is maintained and developed by the MariaDB Foundation and community contributors with the intention of it remaining GNU GPL software From the prerqusite, install and securing MariaDB.

The article will be divided up to 3 sections:

As usual, when we install new software, we must first update our Centos system.

[ramans@localhost ~]$ sudo yum update
 [sudo] password for ramans: 
 Loaded plugins: fastestmirror, langpacks

The result is as described below :

The next step is to nable the MariaDB repository. We have to create a repository file named MariaDB.repo and add the following content inside it :

[ramans@localhost ~]$ sudo vi /etc/yum.repos.d/MariaDB.repo
name = MariaDB 
baseurl = http://yum.mariadb.org/10.1/centos7-amd64 
MariaDB package enabled on CentOS7
