One thing to check if the redis commands are not working for you is if your redis-server.pid is actually being created. You specify the location of where this file is in

/etc/systemd/system/redis.service 

and it should have a section that looks something like this:

[Service]
Type=forking
User=redis
Group=redis
ExecStart=/usr/bin/redis-server /etc/redis/redis.conf
PIDFile=/run/redis/redis-server.pid
TimeoutStopSec=0
Restart=always

Check the location and permissions of the PIDFile directory (in my case, '/run/redis'). I was trying to restart the service logged in as deploy but the directory permissions were listed as

drwxrwsr-x  2 redis    redis      40 Jul 20 17:37 redis

If you need a refresher on linux permissions, check this out. But the problem was I was executing the restart as my deploy user which the permissions above are r-x, not allowing my user to write to the PIDFile directory.

Once I realized that, I logged in using root, reran the restart command on the redis (service redis restart) and everything worked. That was a headache but hopefully this saves someone a little time.
