I have a server that runs nginx with varnish. I cannot run nginx and varnish at the same time as the they are both trying to listen on port 80.
nginx is configured to listen on port 8080
upstream www {
server 127.0.0.1:9001;
}
server {
listen 8080 default_server;
server_name server.com;
root /var/www/html/;
location /docs/index.php {
fastcgi_pass www;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param HTTPS off;
fastcgi_param SERVER_PORT 8888;
}
}
Varnish then listens on port 80

-u varnish -g varnish \
-S ${VARNISH_SECRET_FILE} \
-s ${VARNISH_STORAGE}"
When I try and restart nginx now I get an error
service nginx restart
Stopping nginx: [FAILED]

If I stop varnish and run netstat I can see that nginx runs on port 8080 and 80
netstat -tulpn | grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 95831/nginx
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 95831/nginx
Checking the nginx config directory, I cannot see anywhere that port is defined
grep -rnw '/etc/nginx/' -e '80'
grep -rnw '/etc/nginx/' -e 'server'
