How To Install MariaDB 10.x on Debian 11

MariaDB is a fork of MySQL database and is developed as an open-source solution, primarily under the GPL license. It is a binary drop-in replacement of MySQL because it shares the same code base with MySQL 5.5 and later versions.

The MariaDB database is a free alternative to MySQL, and most of the enhancements are specifically aimed at high availability, scalability, and performance in data-intensive, business-critical applications. It can run on GNU/Linux, FreeBSD, Solaris, Mac OS X, Windows, and many other operating systems.
