Redis is an open-source, networked, in-memory, key-value data store with optional durability. It is written in ANSI C. It’s a “NoSQL” key-value data store. More precisely, it is a data structure server. 
To install Redis as daemon on a CentOS/RHEL/cPanel server, do the following steps
<pre>cd /usr/local/
wget http://download.redis.io/releases/redis-2.8.12.tar.gz
tar -xvzf redis-2.8.12.tar.gz
cd redis-2.8.12
make
cp src/redis-server /usr/local/bin
cp src/redis-cli /usr/local/bin
mkdir -p /etc/redis
mkdir -p /var/redis
cp redis.conf /etc/redis/redis.conf
</pre>
Open /etc/redis/redis.conf using vi edirot and set the values as follows.
<pre>daemonize yes
port 6379
bind 127.0.0.1
dir /var/redis/
logfile /var/log/redis.log
pidfile /var/run/redis.pid
</pre>
Now create the startup script. Create a new file as /etc/init.d/redis and add the following contents to it ( Reference https://gist.github.com/paulrosania/257849 ). And make it executable ( chmod 755 /etc/init.d/redis ). 
<pre>#!/bin/sh
#
# redis - this script starts and stops the redis-server daemon
#
# chkconfig: - 85 15
# description: Redis is a persistent key-value database
# processname: redis-server
# config: /etc/redis/redis.conf
# config: /etc/sysconfig/redis
# pidfile: /var/run/redis.pid

# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0

redis="/usr/local/bin/redis-server"
prog=$(basename $redis)

REDIS_CONF_FILE="/etc/redis/redis.conf"

[ -f /etc/sysconfig/redis ] && . /etc/sysconfig/redis

lockfile=/var/lock/subsys/redis

start() {
[ -x $redis ] || exit 5
[ -f $REDIS_CONF_FILE ] || exit 6
echo -n $"Starting $prog: "
daemon $redis $REDIS_CONF_FILE
retval=$?
echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}

stop() {
echo -n $"Stopping $prog: "
killproc $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}

restart() {
stop
start
}

reload() {
echo -n $"Reloading $prog: "
killproc $redis -HUP
RETVAL=$?
echo
}

force_reload() {
restart
}

rh_status() {
status $prog
}

rh_status_q() {
rh_status >/dev/null 2>&1
}

case "$1" in
start)
rh_status_q && exit 0
$1
;;
stop)
rh_status_q || exit 0
$1
;;
restart|configtest)
$1
;;
reload)
rh_status_q || exit 7
$1
;;
force-reload)
force_reload
;;
status)
rh_status
;;
condrestart|try-restart)
rh_status_q || exit 0
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload}"
exit 2
esac
</pre>
Now make sure the daemon will start after server reboot.
<pre>chkconfig --add redis
chkconfig redis on
</pre>
Now we can start redis using command /etc/init.d/redis start
To make sure redis is working, run command “redis-cli ping” from commandline. If you get result “PONG”, that shows redis is working.
Now install redis PHP extension, using following command.
<pre>pecl install redis
</pre>
Now open php.ini ( /usr/local/lib/php.ini on cPanel servers ) file and add the following line to it
<pre>extension=redis.so
</pre>
Now restart Apache to apply the changes to php.ini file. 

Redis as a PHP Session Handler

<pre>session.save_handler = redis
session.save_path = tcp://127.0.0.1:6379</pre>

or directly in your page:

<pre>ini_set('session.save_handler', 'redis');
ini_set('session.save_path', 'tcp://127.0.0.1:6379');
</pre>
