How can I stop redis-server?

Question

I apparently have a redis-server instance running because when I try to start a new server by entering redis-server, I'm greeted with the following:

Opening port: bind: Address already in use

I can't figure out how to stop this server and start a new one.

Is there any command I can append to redis-server when I'm typing in the CLI?

My OS is Ubuntu 10.04.

Answer 1

systemd, ubuntu 16.04:

$ sudo systemctl is-active redis-server
active

$ sudo systemctl is-enabled redis-server
enabled

$ sudo systemctl disable redis-server
Synchronizing state of redis-server.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install disable redis-server
Removed /etc/systemd/system/redis.service.

$ sudo systemctl stop redis-server

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.

For osx I created the following aliases for starting and stopping redis (redis installed with homebrew):

alias redstart='redis-server /usr/local/etc/redis/6379.conf'

alias redstop='redis-cli -h 127.0.0.1 -p 6379 shutdown'

This has worked great for me for local development.
