1. check that you can connect with to mysql with password you provided at installation time.
2. check the passwords in /opt/zenoss/etc/global.conf (look for zep-user and zep-password) and try to connect with these credentials to mysql

In case credentials doesn't work just change password in mysql for user specifeid in zep-user (seems to be zenoss) to the corresponding password in zep-password

It all else fails, it wouldn't hurt to do a re-install to make sure
everything got in there!
