Stop redis server. Neither shutdown nor stop works - redis

Question

I want to stop the redis server and it just keeps going and going. I am using redis-2.6.7
Check that it is running:
redis-server
It says "...bind: Address already in use" so it is already running.
I have tried
redis-cli
redis 127.0.0.1:6379> shutdown
It just hangs and nothing happens. I break out and check, yes, it is still running.
I have tried
redis-server stop
I get "can't open config file 'stop'"
I tried:
killall redis-server
Still running.
The reason that I want to stop it is that it is just hanging when I try to set or get a value via Python. So I thought that I would restart it.
EDIT:
No commands seem to work from redis-cli. I also tried INFO and it just hangs.

Answer 1

I finally got it down.
Get the PID of the process (this worked in Webfaction):
ps -u my_account -o pid,rss,command | grep redis
Then
> kill -9 the_pid
I was able to REPRODUCE this issue:
Start redis-server
Then break it using Pause/Break key
Now it hangs and it won't shutdown normally. Also the Python program trying to set/get a key hangs. To avoid this: Just close the window after starting redis-server. It's now running normally.

Answer 2

I can't reproduce the problem anymore, but shutdown NOSAVE helped me, when I was playing with redis and couldn't get it to shut down:
redis-cli
127.0.0.1:6379> shutdown
(error) ERR Errors trying to SHUTDOWN. Check logs.
127.0.0.1:6379> shutdown NOSAVE
not connected>

Answer 3

Shutdown Redis Server $ redis-cli -a password -p 6379 shutdown
Start Redis Server $ sudo service redis_6379 start
It works on Ubuntu Server 14.04 x86 Redis v2.8.15.

Answer 4

Depending on your setup, either of the following solutions might fail, with redis-server just restarting with a new PID:
1.
redis-cli -a password shutdown
or, 2.
ps aux|grep redis
kill -9 <redis pid>
But the below command works.
/etc/init.d/redis-server stop
My server is Ubuntu 18.04.2 and Redis version is v4.0.9

Answer 5

The normal way of doing this is to connect to a client like redis-cli and execute "shutdown" command. I've found some issues trying to shutdown because redis-server doesn't have right permissions to edit db dump file (RDB) prior to quit. Then redis remains started and you have to kill the process with kill -9 pid. But this is not a redis problem as you may know.
Example of this problem:
# User requested shutdown...
[16560] 10 Sep 11:21:17.672 * Saving the final RDB snapshot before exiting.
[16560] 10 Sep 11:21:17.672 # Failed opening .rdb for saving: Permission denied
[16560] 10 Sep 11:21:17.672 # Error trying to save the DB, can't exit.

Answer 6

If You use Ubuntu or other linux distros try stop redis server:
sudo service redis-server stop

Answer 7

i think shutdown command can shutdown the redis server.
Maybe strange,after typed shutdown command,the redis-cli does not exit.Meanwhile ,the server has shutdowned.

Answer 8

This is possibly an really important note for some people reading this. If your redis doesn't seem to be responding to a shutdown. CHECK THE LOGS.
They may say something like this:
Apr 24 00:48:54 redis[828]: Received SIGTERM, scheduling shutdown...
Apr 24 00:48:54 redis[828]: User requested shutdown, saving DB...
Apr 24 00:55:37 redis[828]: DB saved on disk
Maybe your DB is multiple GB, or tens of GBs in which case it will take time to shutdown. If instead you want to clean out all keys, there is a better way to do that than shutdown. FLUSHALL

Answer 9

On windows this worked:
Open terminal(PowerShell/CMD), type:
wsl --shutdown
It will end your virtual machine.

Answer 10

net stop redis
should do the trick
to start :
net start redis
see this https://stackoverflow.com/a/20153062

Answer 11

When setting up the server to require auth...
The redis start and shutdown script utilizes redis-cli, which means that shutdown will not happen without auth and the server will hang in a loop waiting for redis to shutdown, which won't ever happen without auth.
So in the shutdown script you have to change
$CLIEXEC -p $REDISPORT shutdown
to
$CLIEXEC -a 'authpassword' -p $REDISPORT shutdown
in order to allow your redis service to shutdown without hassle.

Answer 12

Best way check pid of redis opened port :
lsof -i:<redis-port>
for default redis port
lsof -i:6379
kill -9 <pid>

Answer 13

I had a Could not connect to Redis at 127.0.0.1:6379: Connection refused error and nothing worked for me from the suggested solutions.
My solution: run sudo redis-server /etc/redis.conf command in the terminal.
After running the command I was able to use Redis again without that error.
Note: I do not know if it is OS-dependent, but I use Manjaro Linux. I am not sure if it will work the same on a different OS.

Answer 14

You use the following command to kill the running redis-server process.
ps aux |grep redis
This will list all the running processes for redis-server.
Then you can use the following command to kill the redis processes
sudo kill <pid for redis>
sudo kill 7229 //for the above sample.

Answer 15

start redis: $REDIS_HOME/src/redis-server
stop redis: $REDIS_HOME/src/redis-cli shutdown
$REDIS_HOME where you have installed/extracted redis.

Answer 16

on redis-cli command "shutdown SAVE" or "shutdown NOSAVE" will work.
