[Mediawiki-l] Setting for MySQL Server?

[Brian Finifter]

I'm attempting to install MediaWiki on a sub domain of my website, as in:

http://wikifilm.riddleplayersproductions.com

On the installation screen, I've got everything else down properly, at
least nothing is giving me an error message still, except for the
MySQL server. I thought it was simply just typing the server that the
database was on, as in riddleplayersproductions.com or
wikifilm.riddleplayersproductions.com, but apparently this is not so.
It's giving me the error message of,"Couldn't connect to database
(2005)"

What am I suppose to enter for this field?

Many thanks,
Brian
