Error with gunicorn server start

On an external server, I tried to run the command:

gunicorn --bind 0.0.0.0:8000 jeremiesblog.wsgi:application

I got this error: 

[2017-01-29 15:08:02 +0000] [19640] [INFO] Starting gunicorn 19.4.5

What can I do to fix this issue?

Solution

  • The error message:

    Connection in use: ('0.0.0.0', 8000)

    Indicates the port is in use. You need to find whoever is currently using the port and turn them off. If you can sudo, you can use netstat to find who is already using the port:

    $ sudo netstat -nlp | grep :80
tcp  0  0  0.0.0.0:80  0.0.0.0:*  LISTEN  125004/gunicorn

    In the example above it is guincorn with a pid of 125004.
