Shutting down Redis

Question

I started up Redis for the first time on my local machine today and then later closed all terminal windows after I shutdown my Rails app. An hour later, I started up the Rails app again and did the following to start the redis server

redis-server /usr/local/etc/redis.conf

However, it told me

# Opening port 6379: bind: Address already in use

I therefore assumed it was still running its earlier instance even though I closed the terminal windows on my Mac.

Looking at this page http://redis.io/commands/shutdown, I tried to run

SHUTDOWN

in the terminal window but I get this response

SHUTDOWN: NOT super-user

I therefore tried (Even though I didn't use sudo to start it)

sudo SHUTDOWN

and after it asked me for my password, it output this

usage: shutdown [-] [-h [-u] [-n] | -r [-n] | -s | -k] time [warning-message ...]

but when I randomly ran shutdown -s it said

 SHUTDOWN: NOT super-user

What's the proper way to shutdown Redis when I close up my app?

Hey, I accidentally downvoted your question 15 minutes ago. I've just realized that but I can't undo it. If you edit it I think I can undo it. I'm really, really sorry. — Leandro Fournier, Aug 24 '15 at 18:01

Use the built-in redis client: redis-cli shutdown

Should be the top answer. – sanny Jul 30 '15 at 13:14

This is meant to be sent as a command to redis, not to be executed on your terminal.

In this case you can actually just kill redis from the terminal, since upon receiving a SIGTERM signal it will schedule a SHUTDOWN instead of simply exiting.

For reference see the signal handling doc page.

actually, running 'kill' gives me this kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec] – BrainLikeADullPencil Apr 22 '13 at 03:37
You need to provide the Process ID to kill, so it knows where to send the SIGTERM signal. Take a look at this: http://unixhelp.ed.ac.uk/CGI/man-cgi?kill – Nathan Apr 22 '13 at 03:39

ok, for anyone looking at this answer, I got the process id by doing 'redis-cli info | grep process_id' and then ran 'kill 2694' – BrainLikeADullPencil Apr 22 '13 at 03:42

"ps aux | grep redis" is the normal way, fyi :) – Kevin Sep 27 '13 at 22:45
how to tell ps to include column headers ? – BaltoStar Oct 29 '14 at 00:41

Find out the process id of the Redis instance running on your machine...

> ps aux | grep redis

impadmin 23277  0.0  0.0  35044  1976 pts/2    Sl+  14:19   0:00 src/redis-server

... and then run:

> kill 23277

I tried this approach, but kept noticing that my `redis-server` process kept changing its PID for some reason... So each time I ran `ps aux | grep redis` the displayed PID would be different from the previous run of `ps aux | grep redis`. Ultimately `redis-cli shutdown` was what I wanted. – mecampbellsoup Feb 12 '16 at 18:54
