====== Redis ======

Redis is an in-memory data structure store, it listens on port 6379.

I just wanted to see if redis was in use on a server so this was just enough to establish there were no keys in use and no other processes using it so I could stop it and remove it.

===== Basic Primer =====

Access from a console is best from the ''redis-cli'' command.

<code redis>
-bash-4.1$ redis-cli 
127.0.0.1:6379>
127.0.0.1:6379>
127.0.0.1:6379> info
# Server
redis_version:4.0.9
redis_git_sha1:00000000
redis_git_dirty:0
redis_build_id:c527bae5cf6a6c5e
redis_mode:standalone
os:Linux 2.6.32-696.23.1.el6.x86_64 x86_64
