==Add a second instance of Redis==

Redis is single-threaded so it’s performance peaks when it uses one full CPU core. On a multi-core machine (every machine these days) your peak performance with Redis will be higher if you can use multiple cores. Also, there will be no waiting between different processes. E.g. while one process may be fetching the config, another would be waiting to load a session and another would be waiting to load a FPC record. By having each on a separate core you have much higher peak performance and less contention.

cp /etc/redis.conf /etc/redis2.conf && cp /etc/init.d/redis /etc/init.d/redis2

'''Change'''
vim /etc/init.d/redis2
pidfile="/var/run/redis/redis.pid" to pidfile="/var/run/redis/redis2.pid"
REDIS_CONFIG="/etc/redis.conf" to REDIS_CONFIG="/etc/redis2.conf"

'''Change'''
vim /etc/redis2.conf
port 6379 to port 6380
unixsocket /tmp/redis.sock to unixsocket /tmp/redis2.sock

service redis2 start

'''Let also make this instance start up on boot'''

chkconfig redis2 on

'''Now verify its set to start at boot'''

chkconfig --list redis2
