Enable MySql to run. Create a database called "test" (if you don't already have one) and make sure that "root" or whatever username you're using is able to access the "test" database with your MySql password. Login as "root" during the installation. Be sure to edit below "testuser" and "testpassword" otherwise your installation will not be successful.
