Never used it but your values would be the following. These values would go into the configuration file for the application (they should provide a sample that you can edit). You would first have to create the database, user and add the user to the database through cPanel.
- MySQL host - localhost
- User - cpanel-name_user-you-created
- Password - just-the-password-you-created for above user
- Database name - cpanel-name_database-name-you-created
