mongrel unicorn - Dec 2009 - FreeBSD rc script

Hey Eric,

would you be interested in including a FreeBSD rc.d script ? Here is what my
current one looks like:

in /usr/local/etc/rc.d/unicorn 

#!/bin/sh
#
# PROVIDE: unicorn

. /etc/rc.subr

name=unicorn
rcvar=`set_rcvar`

command=/usr/local/bin/unicorn_rails
command_args="-c /usr/local/etc/unicorn.rb -E production -D"

load_rc_config ${name}

: ${unicorn_dir:=/usr/local/www/}

procname=ruby18

unicorn_chdir=${unicorn_dir}
required_dirs=${unicorn_dir}

extra_commands=reload
sig_reload=USR2

run_rc_command $1


and in /etc/rc.conf

unicorn_enable="YES"
unicorn_dir="/usr/local/www/myprojectroot"


This loads unicorn at startup, gives the usual start stop and restart commands
and has a reload command which sends USR2 to the master process.

Kind regards, John

Hi Paul,

Sure, a few comments below.

Since it''s using a Unicorn config file with USR2, wouldn''t it
have to
use QUIT to complete the actual upgrade?

Not too knowledgeable with FreeBSD init scripts on my end here,
but I''m guessing at how it''d work:

	extra_commands="reexec graceful reload"
	sig_reexec=USR2
	sig_graceful=QUIT
	sig_reload=HUP
