Upstart script to manage a multi instance load balanced installation
After some work i've created an Upstart script which can manage a load balanced galaxy configuration as described in the wiki. I thought that I would put it on this list for other people to use. The script parses universe_wsgi.ini just like run.sh and spawns all of the servers it finds. It comes in two pieces galaxy.conf and galaxy-worker.conf. Once you place them both in /etc/init and make the proper edits for the environment a server can be started with "sudo start galaxy". The configuration starts the server at boot time and puts all of the instances under the management of upstart which deals with pids, logging to syslog and respawning if an instance crashes. I have just gotten this working reasonably well but have done basically no testing so there are bugs to be found. Any comments are welcome if anyone knows a better way to do something here. - Seth *galaxy.conf* ---------------------------- author "Seth Sims <seth.sims@gmail.com>" version "0.0.1 test" description "galaxy master process.

Hi Seth, Thanks for submitting these. I was about to commit them to the contrib/ directory along with the rest of the start scripts, but I was wondering if you could avoid running the check/fetch scripts as root by just using `su -c`? --nate

Dear Nate, Adding "su - galaxy" as the first line of the pre-start script seems to work reasonably well. Also it looks like the line that sets the egg cache is not working properly. My egg cache ends up being "/tmp/${SERVER_NAME}_egg/" but things still seem to be working so I've changed that part to use one directory in /tmp/ for all instances.

Dear Nate, Actually... no, galaxy's home was set to a non-existent directory so the working directory was being changed to the root of the file system. However the script still seemed to work. I changed the script to use "su - galaxy -c" like you show anyway. There seem to be no significant change to the log files with the change. But i'm going to use "su -c" it as you show anyway.
