Unable to kill the port 6379 used by redis-CodePudding

im confuse with redis instalation. I've already tried uninstall redis with any tutorials, also trying uninstall manually. But, redis still used 6379 port.

dna@dna:~$ sudo netstat -tulnp | grep 6379
[sudo] password for dna:

my docker apps used redis already stopped, also the redis image already removed too.

CodePudding user response：

You can find the PID that is listening on port 6379 with the following command: fuser -n tcp 6379

An example:

[root@server ~]# fuser -n tcp 22
22/tcp:               4837 34711
[root@server ~]#

If you cannot stop the service, you can kill it: kill -9 <pid>

CodePudding user response：

What’s the output of ps -auxf | grep -i redis?

Perhaps another redis application is installed, what is the output of apt list installed | grep -i redis?

Also, what is the output of systemctl | grep -i redis

If all that doesn't bring any valueable hints, try to install mlocate w apt install mlocate -y ; updatedb.

Then perform a search for every redis file on disk:

locate -i redis

CodePudding user response：

u can try to login in as root,then unistall redis-server.Because the account dna is not access to read the file /var/lib/dpkg/lock-frontend
