I'm not sure where you want your error log to appear but it works pretty slick if you use the daemontools multilog program to handle it. It rolls at a specified size and you specify how many historical files you want to keep. In this way, you are *guaranteed* that you can control the maximum storage space used. You will *never* have an exhausted filesystem if you set it up this way. Of course, since it's a DJB tool, it's a bit cryptic. But you can work through that if you download and install the separately published man pages for daemontools.
If you have a directory (or symlink to a directory) named 'log' in your service directory (the same location you placed your daemontools 'run' file), and if that log directory contains a file named 'run' that invokes multilog, then 'supervise' (the daemontools daemon that runs and watches *your* daemon) will automatically control the log file process. I previously published an article in these forums that describes a setup using 'multilog'. You can search for that or look at my postings.
A possible setup may look like this:
- /service/service0 is a symlink to your openacs root (say /home/servers/service0)
- your openacs root contains a 'run' script [1]
- your openacs root contains a symlink named 'log' that points to your log directory (say /var/log/aolserver/service0)
- your log directory contains a 'run' script [2]
Once you're up and running, you can control log rolling manually if you wish by:
svc -a /service/service0/log
If for some reason your log isn't showing any content, you may have the file descriptors honked, possibly by moving or removing a log directory while there is an active 'supervise' process directing the flow. In that case, you can straighten things out by:
- remove your service's symlink from /service
- svc -xd /home/servers/service0/log
- svc -xd /home/servers/service0
- recreate your service's symlink in /service
- 'svscan' should now automagically restart everything
[1] your service 'run' script
#!/bin/sh
export AOLSERVER_HOME=/home/aolserver
exec 2>&1
exec $AOLSERVER_HOME/bin/nsd -fzt \
/home/servers/service0/openacs4.tcl \
-u nsadmin -g web
[2] your log 'run' script
#!/bin/sh
exec setuidgid nsadmin multilog s3999999 +* ./error
Good luck.
