Please enter the database information you're told to use by your host.

For most cases, the MySQL server should be "localhost", and the username should be your username (for CPanel, etc.).  Same with your password.  Database name is probably going to be your username again, or perhaps username_somethingyoumadeincpanel.  Prefix can be anything, even blank.
