    Running redis using upstart on Ubuntu

I've been trying to understand how to setup systems from
the ground up on Ubuntu. I just installed redis onto
the box and here's how I did it and some things to look
out for.
To install:
sudo apt-get install redis-server

That will create a redis user and install the init.d
script for it. Since upstart is now the replacement for
using init.d, I figure I should convert it to run using
upstart.
To disable the default init.d script for redis:
sudo update-rc.d redis-server disable

Then create /etc/init/redis-server.conf with the following
description "Redis Server"
author "Thomas Woolford <thomas@urpages.com.au>"

# run when the local FS becomes available
start on local-filesystems
stop on shutdown

# The default redis conf has `daemonize = yes` and will naiively fork itself.
expect fork

# Respawn unless redis dies 10 times in 5 seconds
respawn
respawn limit 10 5

# start a default instance
instance $NAME
env NAME=redis

# run redis as the correct user
setuid redis
setgid redis

# run redis with the correct config file for this instance
exec /usr/bin/redis-server /etc/redis/${NAME}.conf

What this is is the script for upstart to know what command to run
to start the process.
Now you can use the folowing commands to control your redis-server:
sudo start   redis-server [ name=redis ]
sudo restart redis-server [ name=redis ]
sudo status  redis-server [ name=redis ]
sudo stop    redis-server [ name=redis ]

Hope this was helpful!
