socket.error: [Errno 98] Address already in use

[Pingpan Cheng]

Hi all,

I reinstalled the frappe-bench and then encountered some problems. When I tried to start the erpnext, it shows me the error as the title.

The detailed logs:

socket.error: [Errno 98] Address already in use

I tried to kill all the processes using port 8000 but it doesn't work. I tried to restart and then ran it again, the same error showed again. So I thought the problem doesn't lie in the port number? How to fix this? 

I noticed that there are similar posts, but there are no detailed solutions.

Thanks very much!

Are you running something else on port 8000?

Did you also follow the production deployment steps? Because if you
did, this explains. gunicorn (production webserver) runs on port 8000.
If you kill it, supervisor will start it again (that's it's job).

Hi Pratik,

I think gunicorn is the cause.

$ lsof -i :8000

COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

gunicorn 3472 life    5u  IPv4  16913      0t0  TCP localhost:8000 (LISTEN)

gunicorn 3477 life    5u  IPv4  16913      0t0  TCP localhost:8000 (LISTEN)

gunicorn 3478 life    5u  IPv4  16913      0t0  TCP localhost:8000 (LISTEN)

But how can I kill the gunicorn completely? Since supervisor will start it again once I killed it.

Thanks,

Pingpan

Like Frank Underwood, stop supervisor

`sudo supervisorctl stop`

But if you don't want to develop and just use ERPNext, it should be
accessible on port 80 (assuming nginx is also on).
