It looks to me like your passwords may have gotten out of sync during the installs. Try this:

>su zimbra
>/opt/zimbra/bin/mysql.server start

See if it starts. If it starts, or says that a PID exists, then try:
>mysql msyql

If it lets you in, then your passwords are fine, and you can ignore this. If it says Access Denied, then search the forums on how to reset your logger and mysql passwords using the --skip-grant-tables option.

Let us know.
