# mongrel_railsd Startup script for the Mongrel On Rails Proxy Server
#
# chkconfig: - 85 15
# description: Mongrel is a proxy server for Rails. It is simple to
# use and stable enough for production. Lhttpd is faster but more
# complexe to setup.
# This start script is the product of Philippe Laliberte ©2008 and is public
# domaine and without any warrenty of any sort.
#
# processname: mongreil_rails
#
# domainlist: Serves to start multiple proxy server for multiple
# domaines Needs one at least
#
# vhosts_f: rails applications container (at least one application
# folder per domain)
#
# <env>Ext: I like to have a current copy of the production (ProdExt)
# site when I do evolutions and I always run my tests and do
# my user acceptance tests in a blank site (TestExt) so I
# have normalised forder names for each application
# accordingly. _NOT_IN_USES serves to keep this script for
# trying to do anything on the so marked level of
# application. Do not create a folder with that extention in
# the vhosts container, this would try to start it.
#
# <env>Path: the script will look for applications build with the
# concatenation of $vhosts_f/<domain name><env>Ext to start
# all the instances
# ex. for the domaine r24.ca user acceptance test
# environment it would be /var/www/vhosts/r24.ca if the
# TestExt="" or /var/www/vhosts/r24.ca_dev in development
# if the DevExt=_dev .
#
# If the script does not find the folder it does not try to
# start a proxy for that combinasion of domain and
# level. So do not worry if you have an test site for
# domain A but not for B. This will handle it nicely.
#
# configuration files are expected in:
#
# $vhosts_f/<domain name><env>Ext/config/mongrel.cfg
#
# It is where you tell mongrel_rails where the pid, lock
# and log files are to be found. It is also where you
# define all other instance related details (port number,
# etc.). If it is not found the script will refuse to start
# the proxy.
#
# To be noted that you must put into a configuation file for apache
# Virtualhost where to find the proxy.
# <VirtualHost *:81>
