When you create a Database in your CP, you will see what your details are.

In example, if you create a database named "social", the actual database name will be: "cp_username_social".
If you create a user for the database, named "matt", the actual name of the user will be "cp_username_matt"

The password instead, will remain as you create it.

The host is "localhost"

After that, make sure that you ADD this user to the specific Database.

Take all these details and replace them in your script.
