[Mediawiki-l] maintenance of database

[Russell, Elizabeth]

I inherited a wiki on a Linux system that was installed using xampp, put
out by apachefriends.org.   It's worked great.  It was preconfigured for
PHP, apache, mySQL, Perl, etc.  
 
Now the database admins want to get involved, but it looks like mySQL
was installed using the root userid and password.  They say this is a
problem, and are suggesting it would be best to reinstall mySQL to set
up a DBA userid and password.
 
Has anyone else gone through this?  and if I do need to reinstall mySQL
what else do I need to reinstall?  
 
Thanks,  Beth
