How do I configure another instance of redis on ubuntu?

Question

I basically want to have 2 instances of redis on Ubuntu. I looked at /etc/init.d/redis-server script and tried to create a new one (redis-server-dev) pointing to another config file (new port etc) but it didn't seem to work.

What is the correct procedure?

Thanks

1. Create a new config file in /etc/redis/redis-new.conf (copied from redis.conf). Change the pidfile, port, logfile, dir (for the default db)

2. Create a new file /etc/init.d/redis-server-new (copied from the file redis-server). Change the name, pidfile (same as in the config file in 1), deamon_args (the path to the config file in step 1).

3. Make the new file executable: chmod +x /etc/init.d/redis-server-new

4. Register the new deamon: update-rc.d redis-server-new defaults
