Provide the information needed to connect to the database instance.

  • Database Host Address: If you are using a local database, leave the field blank (the default value is localhost). Otherwise, enter the IP address of your remote database.

  • Root user/password: this is the account that will be used to install the databases.

    • if this is the default account (root), the root password of the database is the password you have defined when executing mysql_secure_installation (whether you have installed Centreon from packages or from sources).
    • if you have defined a custom user with root privileges on all databases (e.g. during the process of installing a remote database), use this one. This user can be deleted once the web installation process is finished.

  • Database user name/password: the credentials of the account that will be used to interact with the Centreon databases. The account will be created when the database is installed.
