MariaDB is a popular relational SQL database that was forked from MySQL server. Ansible roles debops.mariadb and debops.mariadb_server allow you to manage a MariaDB server and / or access it remotely from other hosts.

debops.mariadb_server role is the "server" part - it installs mariadb-server Debian package, and configures access to the database from local root account. After that, you can use debops.mariadb role to manage databases and user accounts on the server.
