Question

I have a static website served up by nginx right now, and I want to develop an app with Tornado on the same server.

The Tornado documentation mentions that wsgi doesn’t support non-blocking requests.

Is there a way for me to get them to work together (on the same server)?

Answer 1

Sure you can. Take a look at the nginx.conf example on tornado’s homepage.

The relevant bits in your case would be:

http {
    # Enumerate all the Tornado servers here
    upstream frontends {
        server 127.0.0.1:8000;
        server 127.0.0.1:8001;
        server 127.0.0.1:8002;
        server 127.0.0.1:8003;
    }
    ...
    server {
        ...
        # for your "static" website
        location ^~ /static/ {
            root /var/www;
            if ($query_string) {
                expires max;
            }
        }
        # for your tornado's app
        location / {
            proxy_pass_header Server;
            proxy_set_header Host $http_host;
            proxy_redirect false;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Scheme $scheme;
            proxy_pass http://frontends;
        }
        ...
    }
    ...
}
