This article covers how to install and Secure MariaDB on a CentOS 7 server. MariaDB is a fork of MySQL managed by the original MySQL developers. It's designed as a replacement for MySQL, uses some commands that reference mysql, and is the default package on CentOS 7.


To Install MariaDB 5.5 on CentOS 7:

1. Install the MariaDB package using the yum package manager: 

$ sudo yum install mariadb-server

2. Once the installation is complete, start the MariaDB service and enable it to start on boot using the following commands: 

$ sudo systemctl start mariadb 
$ sudo systemctl enable mariadb


To install MariaDB on CentOS 8:

1. Open the terminal application. Another option is to log in using the ssh command:

 ssh user@centos-8-server-ip

2. Install the MariaDB on CentOS 8 by running the command:

$ sudo yum install mariadb-server

3. Secure the MariaDB server in CentOS 8 by running the command:

$ sudo mysql_secure_installation

4. Finally test MariaDB installation by running the command:

$ mysql -u root -p


MariaDB vs MySQL:

Even though MariaDB is a fork of MySQL, these two database management systems are still quite different: 

MariaDB is fully GPL licensed while MySQL takes a dual-license approach.

MariaDB supports a lot of different storage engines. 

In many scenarios, MariaDB offers improved performance.
