I have redis v2.8.19-2 installed on my CentOS 6.5 server.

# rpm -qa | grep redis
redis-2.8.19-2.el6.art.x86_64

I have just commented out below line from stop () function and assigned retval=1

stop() {
    echo -n $"Stopping $name: "
    #[ -x $shut ] && $shut
    retval=1
    if [ -f $pidfile ]
    then
        # shutdown haven't work, try old way
        killproc -p $pidfile $name
        retval=$?
    else
        success "$name shutdown"
    fi
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
}

Now, it does not throws error in stop, start, status, or restart.

Hope this helps someone.

This script is not working for me. Anyone know what is going on?

Starting redis-server: chown: invalid user: redis:redis' /usr/bin/dirname: extra operand.pid'
Try `/usr/bin/dirname --help' for more information.
runuser: user redis does not exist

@tpaveyjr I used the https://gist.github.com/tahajahangir/155176867afed0ff80ad fork and had the same problem (on CentOS 6.6). Solved by adding --pidfile "/var/run/redis.pid" to the daemon call

This didn't quite work for me, so I tweaked it to use more generic/plain constructs: https://gist.github.com/ac-astuartkregor/5d11fe0e9f028087b66ac90423293263
This assumes you've told redis to run with daemonize yes in the config.
