Most of the time when I reboot my Ubunutu server, I get "Waiting for Redis to shutdown…" over and over and it never stops until I force reboot. What could cause this?

I have http://godrb.com/ monitoring that resque stays running, so it could be related to that.

  • Is redis actually running as the PID that it has in the pidfile? Ubuntu will try to shut it down by killing it using something like kill $(cat /var/run/redis.pid) or something along those lines. If the pid file is incorrect, it will fail at killing redis.

    Actually, if you're using god, you should probably, uh, kill god before anything else.

  • Ok, thanks. So I need to manually kill god before each reboot?

  • Try this: make sure god is stopped before the reboot, and see if the problem happens.

  • The pid files (there are 2 resque processes running) are correct. I can kill the processes in the way you suggested. Now what can I do to not have to manually stop them before every reboot?

Do you have Redis listening on an interface other than localhost or 127.0.0.1? If so, the stop command is never being sent to the right interface, as the official Redis init template fails to include the host address.

In the /etc/init.d/redis files I’ve worked with, I had to define REDISHOST=10.150.0.18 and then on line 30 (look for “shutdown”) add that host argument:

$CLIEXEC -h $REDISHOST -p $REDISPORT shutdown

If you were like me, you required a password (requirepass) in your redis.conf. the redis-cli command won't respond without the password now.

In the first few lines of your /etc/init.d/redis file look for CLIEXEC and change the default

CLIEXEC=/usr/local/bin/redis-cli

to 

CLIEXEC="/usr/local/bin/redis-cli -a <password>"

Please take note of the quotes.

When I did this I didn't have to include the -h $REDISHOST parameters.

    That fixed the issue for me; however if you copy/paste this to replace the entire line please note that CLIEEXEC is misspelled. I don't have the reputation score to edit it myself.

The conversation in this list can solve your problem:

Modify your init script to use '-a' (auth) in the redis-cli call.

CLIEXEC="/usr/local/bin/redis-cli -a password"

In other words, the problem is the fact that you have to enter the Redis password to stop the service. Modifying the /etc/init.d/redis_port script (or any other init script you might have) with -a password will solve it.

you can kill the redis process:

$ ps -ef|grep "redis"

# kill $(cat /var/run/redis.pid)
