An open-source database management system, MariaDB is commonly installed as part of the popular LEMP (Linux, Nginx, MySQL/MariaDB, PHP/Python/Perl) stack. The data is managed by MariaDB by using a relational database and SQL (Structured Query Language). It acts as a fork of MySQL that is managed by the original MySQL developers. Since it’s designed as a replacement for MySQL, it uses commands that reference mysql and is the default package on CentOS 7.
This tutorial explains the installation of the latest version of MariaDB on a CentOS 7 server.
