Nginx refuses to bind to 8080

Question

I have setup Varnish to run on port 80 which seems to work fine.

COMMAND   PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
varnishd 8005 nobody    7u  IPv4  14055      0t0  TCP *:http (LISTEN)
varnishd 8005 nobody    8u  IPv6  14056      0t0  TCP *:http (LISTEN)

Under available sites in /etc/nginx I have the file default with:

server {
  listen 8080;

....

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

Why is it still looking for port 80?

Answer 1

You should add

listen 8080 default;

And make sure that in other configuration files or virtualhosts there is no other default port 80.

Answer 2

You have a directive somewhere that is telling nginx to bind to port 80 find it and make the necessary change

cd /etc/nginx
grep -rw 80 *

Should get you looking in the right place.
