 Replication settings. Set `mysql_server_id` and `mysql_replication_role` by server (e.g. the master would be ID `1`, with the `mysql_replication_role` of `master`, and the slave would be ID `2`, with the `mysql_replication_role` of `slave`). The `mysql_replication_user` uses the same keys as `mysql_users`, and is created on master servers, and used to replicate on all the slaves.
 
+### MariaDB usage
+
+This role works with either MySQL or a compatible version of MariaDB. On RHEL/CentOS 7+, the mariadb database engine was substituted as the default MySQL replacement package, so you should override the `mysql_packages` variable with the below configuration to make sure MariaDB is installed correctly.

+#### RHEL/CentOS 7 MariaDB configuration

+Set the following variables (at a minimum):
+
+    mysql_packages:
