After spending too many hours trying to get tracd running as a daemon on Ubuntu 10.04 I might as well share my experiences. At first I begun with some init.d scripts I found googling for tracd init.d. The problem with them was that they were made to run tracd as root which frankly didn’t feel that great. I tried to modify them to use the –user/–chuid options to no avail. In the end I understood that the problem was not those options but that the pid file I was trying to use with the tracd command for some reason couldn’t be written.
These mishaps wasn’t only bad as I therefor started fiddling with upstart. upstart is a much more pleasant experience than classical init scripts. All I had to do was to create the file
description "tracd server" author "KO" start on startup stop on shutdown expect daemon script exec sudo -u www-data /usr/bin/tracd --daemonize --port=8000 \ --hostname=127.0.0.1 -s /path/to/trac/project end script
The key here was the expect daemon stanza which saved my day. After that you can use start|stop|status processname like:
sudo start tracd
Now you might wonder why I wanted to run tracd as a daemon. I was about to switch to nginx on the server running trac and the daemon way seemed the easiest.
