While trying to finally deploy my NEW rover web app a problem occured. I already configured Gunicorn and bind it to 0.0.0.0:80 (with wsgi). Website loads, but without any images, css, javascript files (even "admin" site is without any style). Postgres is installed and running fine. I already did

python manage.py collectstatic

python manage.py migrate

I watched tons of tutorials how to do it. But still after I try to run:

systemctl status nginx.service

i get an error:

Job for nginx.service failed because the control process exited with error code. 

See "systemctl status nginx.service" and "journalctl -xe" for details.

nginx is telling you, it cannot bind to port 80 as some other process is already listening on this port. You can see this in your log output here:

nginx[5957]: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

To check which process is listening on this port you could use netstat or better ss:

~# ss -naptu state listening | grep :80

tcp   0      128       0.0.0.0:80                    0.0.0.0:*                   users:(("nginx",pid=6824,fd=4),("nginx",pid=6823,fd=4))

 ~# netstat -tulpen | grep :80

tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      0          136280382  6823/nginx: master 

The last column will show the process name and the pid of the process listening on the port.
