nginx always serves welcome page

Question

I'm trying to make nginx proxy requests to a Django server, but it keeps showing the nginx welcome page.

Here's /etc/nginx/nginx.conf:

worker_processes  4;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile       off;

    tcp_nopush     on;

    keepalive_timeout  65;

    gzip  on;
    gzip_disable "msie6";

    include /etc/nginx/sites-enabled/*;

    server {
        listen 8000 default_server;
        listen [::]:8000 default_server ipv6only=on;
    }
}

and here's /etc/nginx/sites-enabled/dotmanca (the only file in the site-enabled directory):

server {
    server_name _;

    access_log off;

    location /media/ {
        alias /vagrant/media/;
    }

    location /static/ {
        alias /vagrant/static/;
    }

    location / {
        proxy_pass http://127.0.0.1:8001;
        proxy_set_header X-Forwarded-Host $server_name;
        proxy_set_header X-Real-IP $remote_addr;
        add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"';
    }
}

So with no server running on port 8001, I expect a bad gateway error to show up. Instead I see the default "Welcome to nginx!"

Running sudo nginx -t gives the following:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Also, sudo service nginx restart appears to do nothing.

My nginx version is 1.4.6, and it's running on Ubuntu Trusty.

Answer 1

So removing the server section from /etc/nginx/nginx.conf and adding the two listen directives to the server section in /etc/nginx/sites-enabled/dotmanca appears to work.

Or at least, it allows sudo nginx -s reload to fix the issue.
