Run multiple Redis servers on Ubuntu

This is a way to run multiple redis server on one ubuntu server.

These steps you have to do only once:

• Adjust init script

Change some Variables.
From this:

DAEMON_ARGS=/etc/redis/redis.conf
NAME=redis-server
DESC=redis-server
PIDFILE=/var/run/redis.pid

to this:

NAME=`basename ${0}`
DAEMON_ARGS=/etc/redis/${NAME}.conf
DESC=${NAME}
PIDFILE=/var/run/${NAME}.pid

• Move redis configuration
  ^
  mv /etc/redis/redis.conf /etc/redis/redis-server.conf

These steps you have to do for every new redis server:

• Copy configuration:
  ^
  cp /etc/redis/redis-server.conf /etc/redis/redis-server2.conf

• In the /etc/redis/redis-server2.conf you have to change at least this options:
  ^
  pidfile /var/run/redis-server.pid
  port 6379
  logfile /var/log/redis/redis-server.log
  dir /var/lib/redis

to this for example:

pidfile /var/run/redis-server2.pid
port 6380
logfile /var/log/redis/redis-server2.log
dir /var/lib/redis2

• Symlink the init script:
  ^
  ln -s /etc/init.d/redis-server /etc/init.d/redis-server2

• Create working directory:
  ^
  mkdir /var/lib/redis2; chown redis.redis /var/lib/redis2;

• Start server and add init script to system startup
  ^
  /etc/init.d/redis-server2 start
  update-rc.d redis-server2 defaults
