Howdy, I'm still fiddling with the install of my two-server cluster. There's supposed to be one mail and one web server, the former has the ISPConfig control panel installed and is working fine as far as I can see. However, in trying to debug why the other one won't join properly, I found the mail server's /var/log/ispconfig/ispconfig.log is filling up with "03.07.2012-17:40 - ERROR - MySQL is down! Rescue will not help!" messages. from the cron job The web interface works and I can log on to MySQL using the mysql client and the credentials from /usr/local/ispconfig/interface/lib/config.inc.php, so I'm at a loss why any part of ISPConfig would not be able to connect. It would be interesting to get a backtrace for this, so unless someone can can tell me already what I'm doing wrong, maybe PHP can be coaxed to produce an execution log or something?
