Flood: Nginx reverse proxy not working

[veganexe]

My nginx root is /usr/share/nginx/html/ and flood is at /root/flood/. But the reverse proxy searches for flood at nginx root.

I followed the wiki for the location block. And changed the base uri in flood's config.

But I get a blank page, but the title bar says "Flood"

Here is the nginx error log

[liquidox]

Working fine with Nginx reverse proxy here.

Flood
baseURI: '/',

Nginx

  location  / {
    proxy_pass  http://hodor:3000/;
  }

Very standard settings worked fine basically.

[veganexe]

Well, your conf is just proxying from http://hodor:3000/ to http://hodor/ if I'm not wrong. What I want is it to proxy to http://hodor/flood/ where the flood folder is outside the nginx root.

[liquidox]

Ah right, my proxy is actually running in a separate LXC. Not sure what's up then...

[veganexe]

UPDATE

Used the following config to atleast stop showing a blank page :

        location /flood/ {
            rewrite ^/flood/(.*) /$1 break;
            proxy_pass http://139.59.81.38:3000/;
            sub_filter 'action="/'  'action="/flood/';
            sub_filter 'href="/'  'href="/flood/';
            sub_filter 'src="/'  'src="/flood/';
            sub_filter_once off;
        }

Note that it shows the login page right away. Even though I did not create an account in Flood yet.

Here is the nginx error log after the edit.

[veganexe]

Someone please post a working .conf for proxying to http://IP/flood where the flood folder sits at /root/ i.e /root/flood. Using subdomain proxying or moving the flood folder into the nginx root is unfortunately not an option for me.

[jfurrow]

Please read the nginx docs, or ask for help in an nginx-related forum.

[veganexe]

Can you tell me where the flood/ folder has to sit for the nginx location block you have put up in the wiki?

[NoeelMoeskops]

same problem. Other proxy's work fine tho.
@veganexe Did you find a solution?

[dcousens]

@veganexe

        upstream flood { server 127.0.0.1:3000; }

        # snip

        server {
                listen 80;
                server_name _

                location / {
                        return 200 "<h1>Foobar</h1>";
                        add_header Content-Type text/html;
                }

                }
        }

With baseURI set to /flood.

[NoeelMoeskops]

@dcousens Thanks for the response.
I did what what you suggested, but I still only have a blank page...
Tried it with floodServerHost: '0.0.0.0' and '127.0.0.1. Not sure if it would make any difference.

I also tried a other method suggested by @jfurrow rewrite ^/flood/(.*) /$1 break; in location /flood/ but no luck.
