Woo to folks with web sites hosted here,

One of the things that bugged me about the server was that, when it rotated the logs, it basically made the web server unavailable for about half an hour. Now true, this is about 4:30am on a Sunday morning, but hardly optimal, and a bit scary when you see "Server down!" emails for the fist time.

The problem was that this is the default web log rotation as set up when I installed the server:
/virtual/www.acornarcade.com/weblogs/access_log /virtual/www.acornarcade.com/weblogs/error_log {
    missingok
    weekly
    prerotate
      ADVXctl closelogs
    endscript
    postrotate
      ADVXctl closelogs
    endscript
}
...which I just copied for each of the virtual hosts (of which there are now many). ADVXctl seems to be the same as apachectl, and closelogs restarted apache.

I took a look at the man pages, and came up with this:

/virtual/www.*/weblogs/*_log {
    missingok
    weekly
    rotate 5
    copytruncate
    delaycompress
    sharedscripts
    prerotate
      date
    endscript
    postrotate
      apachectl graceful
      date
    endscript
}

...which should do all the websites in one go, and only restart the server once.

The "date" commands were to give me a new timing for how long the process takes. This appears to have reduced it from about half an hour to... 21 seconds. Now true, this week it didn't do any compression (there are now four compressed logs, and one - the latest backup - is uncompressed), but that seems like a scarily large difference.

So, now would be the time to let me know if you see any problems with you stats, or bizarre log problems.
