= Init script for Debian =

This is an init script for Debian. Save as {{{/etc/init.d/django}}} and run the following command:
{{{
update-rc.d django defaults
}}}

By default the script expects Django sites in {{{/var/lib/django/<project>}}}. It will store PID files in {{{/var/run/django}}}. These directories must already exist.

The settings may be overridden in a settings file located at {{{/etc/defaults/django}}}. You must at least set the {{{DJANGO_SITES}}} variable. An example is included below.

### BEGIN INIT INFO
# Provides:          FastCGI servers for Django
# Required-Start:    networking
# Required-Stop:     networking
# Default-Start:     2 3 4 5
# Default-Stop:      S 0 1 6
# Short-Description: Start FastCGI servers with Django.
# Description:       Django, in order to operate with FastCGI, must be started
#                    in a very specific way with manage.py. This must be done
#                    for each Django web server that has to run.
