VHosts Nginx Config for Playframework Websockets

Question

The config below seemed to have worked but now its failing. I followed this article to download and install the tcp_proxy_module.

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


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

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    #server {

    #}


    # another virtual host using mix of IP-, name-, and port-based configuration

    server {
        listen       80;
       #listen       locahost:8080;
        server_name  localhost.in;

        location / {
            proxy_pass http://127.0.0.1:9000;
        proxy_set_header        Host            $host;
         }
    }

}

Update:

Updated 2:

With this config I get a bind exception when I start nginx. If I remove the tcp settings, nginx comes up alright. I need port 80 to redirect to 9000 for both regular http requests as well as WebSocket requests

    }
    }

}

It looks like it's just the websockets that are not working. Please read the article you linked again. You did not modify your nginx configuration.

According to that article, a sample configuration for you might look like this (I have not tested it yet, though):

tcp {
    upstream websockets {
        ## Play! location
        server 127.0.0.1:9000;
    }   

    server {
        listen 80;
        server_name localhost.in;

        tcp_nodelay on;
        proxy_pass websockets;
    }
}
