[Mediawiki-l] Database config

[Steve VanSlyck]

I find the new wiki install config screen englessly confusing. Here are 
some of my questions:

1. For the "Database Config" section, am I providing a NEW username and 
password, or suppling a pre-existing one?

2. Does the "Database Config"  username and password have to be the same 
as the "Site Config" username and password? Why are "wikidb" and 
"wiiuser" prefilled? I ask because using these has never worked for 
installs to my local box.

3. When installing to a webserver, not on my local box, how do I know 
what to enter in the "Database Host" field?

4. What is the superuser account? How do I know if I need to create one? 
Am I providing a NEW username and password for a superuser, or suppling 
pre-existing information for a currently existing superuser? Why is 
"root" prefilled? I ask because using root has never worked for installs 
to my local box.

These instructions just don't help me - I don't know why some things 
work and others don't - possibly because I don't know what I'm doing at 
all and can't find a tutorial on this information anywhere.
