MySQL access issue

[Phil Perrin]

Hello everyone,
 
Kind of an oddball question but I'll try to make it as clear as
possible. 
We have a Solaris server, that we have root access to. It houses mysql
db's and information.
I was not the admin for the db's and frankly I'm not an MySQL buff to be
honest.
 
Our DB Admin is gone now, I need access to mysql db's, but I don't know
what the username/password was for them. What are my options here to be
able to not lose this info and get root access into the db's in
mysql?????
 
Thank you,
 
~Phil
