Mongrel users - Sep 2006 - Running Shell Scripts/Commands at Startup?

Someone on the Rails list mentioned that they thought it was possible to get
Mongrel to launch other processes at start time.

I have an app that relies on backgroundrb and also an external listening
program and I''d love it if I could set it up so that when Mongrel
starts,
these start as well.

Is it true that this can be done?

Where would I look for documentation on this?

I thought perhaps the -S option might help but it looks like that''s for
something else.

Thanks,
H

I think that "someone" was me. According to Zed :

You could put it in a mongrel.conf and just have Mongrel run it
on

I am not entirely sure, what Zed meant by inside Configurator, but you can
always write a ruby program, which will fork the process and detach itself
from the current process using Process.detach.

So, technically this script should work:

exec("rake backgroundrb:start") if fork.nil?
Process.detach

Of course...i haven''t tested it and you need to set some environment
stuff...before you can have access to proper rake command.

between Ezra has already cranked out that script...so wait for his next
shiny release of backgroundrb plugin.
