Assembla Development

1.  Compile NGINX

Create a dir to hold the sources while compiling.

Download NGINX from http://nginx.org/download/nginx-0.7.65.tar.gz

Dowload NGINX Push module from http://pushmodule.slact.net/ in this example we will be using v0.692

Extract both archives side by side and 

cd nginx-0.765/
./configure --add-module=../nginx_http_push_module-0.692/

Check the output for errors, if everything looks ok do:

sudo make && make install

2. Configure NGINX

Locate nginx.conf, check /usr/local/nginx/conf/

Now update your nginx.conf and add:

 location ~* /chat/(.*)/publish_chat_messages$ {
    set $push_channel_id $1;
    push_publisher;

    push_authorized_channels_only on;
    push_store_messages on; # enable message queueing
    push_message_timeout 1m; 
    push_min_message_buffer_length 0;
    push_max_message_buffer_length 10;
  }
  # public long-polling endpoint
  location ~* /chat/(.*)/activity$ {
  set $push_channel_id $1;
  push_subscriber;

  push_subscriber_concurrency broadcast;
  default_type text/plain;
  }
 # end Push Configurations

At this point your nginx.conf could look like this:

http {
   ...
  upstream localhost {
    server 127.0.0.1:8080; #where 8080 is the port of your rails server
   }
  server {
  ...
    proxy_buffering off;
    location / {
      proxy_pass http://localhost/;
    }
    Chat specific from above.
  }
}    
  

restart nginx.
