How to Shut Down Your Local Redis Process

You try to start a local redis process with redis-server then see:

...
...
... *:6379: bind: Address already in use

How to shut it down?

$ redis-cli
127.0.0.1:6379> SHUTDOWN

Running redis-cli logs you into the running redis process and allows you to do things like flush the cache (FLUSHALL), and shut down the running process itself (SHUTDOWN).
