I need someone to help me out with a script that I have installed. I need someone to create the MYSQL username and database on a script to get it running.
Have you tried doing it on your own yet? Check out http://wiki.dreamhost.com/MySQL#Creating_a_MySQL_Database_with_DreamHost.
Creating a DB and user is one of the things that DH makes pretty simple. You will have to do that from your DH control panel. Some guys think they are smart enough to write a script to do it but they seldom work. Now adding their information to your configure file is most likely where you are getting into trouble as I seem to recall that they don't use localhost as the host theirs is in the severname.something category. Don't post any personal info in this thread but if you want to post a copy of your empty config file use the php tags. If the program uses an installer program post what it is asking for.
