pls see below:
Though this may be relevant.
mysql.server is not running.
[zimbra@zimbra conf]$ mysql.server status
mysql is running with pid 28362
I've just installed zimbra for testing, thing seem to be good so far.
I wanted to allow mysql to listen on tcp/ip so I changed /opt/zimbra/conf/my.cnf by comment out the "#bind-address localhost".
I though this caused the mysql.server not running error, so I changed it back.
