Daemonizing

Asked by Adam Nelson

Does anybody have best practices for daemonizing Gunicorn, specifically gunicorn_django? Ideally I could run this through 'service' and run something like:

sudo update-rc.d gunicorn defaults

It doesn't look like that's available yet though.

To run gunicorn as a daemon, pass the -D option. See http://manpages.ubuntu.com/manpages/maverick/man1/gunicorn.1.html.

Or are you asking about how to make it start up at boot-time?

I'm sorry, I should have been more clear. I'm looking to handle
starting up at boot time and controlling the process without knowing
the PID (i.e. an upstart or init or supervisord or runit script).

To make gunicorn run via upstart at boot-time (which is probably what you want), add a .conf file in the directory /etc/init for it (you might call it gunicorn.conf), and write the conf file to perform the desired actions. Remember use the command "gunicorn -D" (or, equivalently, "gunicorn --daemon") rather than simply "gunicorn". See http://upstart.ubuntu.com/getting-started.html for information on how to write .conf files for upstart (skip down to "Writing Jobs").

A Google search for "gunicorn upstart" (without the quotes) yielded, among other things, https://gist.github.com/500414/ebf54c086c9a38840655454337a4d83fac89c46f, which might be a source for ideas (if you have to do more than just start gunicorn and let it run, which can do with a single "exec gunicorn -D" stanza).

Thanks for the help. We ended up using supervisord because it was easier to set up for our situation (we need 8 different workers with different settings files). One thing to note when using supervisord is to not use the -D flag (supervisord wants a non-daemonized process).
