Provide the information needed to connect to the database instance.

By default, the instance address is set to localhost, the instance root user is set to root and the root password is empty. Since MariaDB 10.5, it has been mandatory to add a password for the root user. The Root password of the database is the password you have defined when executing mysql_secure_installation (whether you have installed Centreon from the ISO, from packages or from sources).

If you use a remote database server, or use a specific root user, change these entries

Then define the databases' names and credentials that will be created. We recommend to use default values.

Centreon database's user password and the root password should be the only parameters customized here.
