Mongrel / Nginx on Ubuntu: Can't see it in a browser

I have an existing rails app I’m developing on for a client and need to
run in a local environment on my home box.

I’m running Ubuntu/Feisty and I followed this tutorial:
http://www.urbanpuddle.com/articles/2007/05/09/install-ruby-on-rails-on-ubuntu-feisty-fawn

It is mistake-laden but I managed to get things working for the most
part. The only problem is… I’m not sure how to hit the application
itself in the browser. The way he has nginx set up, it has both
phpmyadmin, and the rails app listening on port 80. It DOES serve
phpmyadmin, but I have no idea how to make it bring up my own app (at
/var/www/projectpoll/).

I tried specifying the port, but I can tell I’m just not getting
SOMETHING.

Here’s what my nginx.config looks like:

user www-data www-data;
worker_processes 3;

error_log /var/log/nginx/error.log;

pid /var/run/nginx.pid;

events {
worker_connections 1024;
}

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

log_format  main  '$remote_addr - $remote_user [$time_local] $status


'“$request” $body_bytes_sent “$http_referer” ’
‘“$http_user_agent” “http_x_forwarded_for”’;

#access_log  logs/access.log  main;

sendfile        on;
tcp_nopush     on;
tcp_nodelay    on;

    gzip  on;
upstream mongrel {
 server 127.0.0.1:8000;
 server 127.0.0.1:8001;
 server 127.0.0.1:8002;
}

server {
    listen       80;
    #listen      192.168.1.1;
    #listen      192.168.1.1:8080;

    server_name  php.mydomain.com;

    #access_log  logs/host.access.log  main;

    location / {
        root   /var/www/phpmyadmin;
        index  index.html index.htm index.php;
    }


    # pass the PHP scripts to FastCGI server listening on

127.0.0.1:9000
#
location ~ .php$ {
fastcgi_pass 127.0.0.1:8888;
fastcgi_index index.php;

                    fastcgi_param  SCRIPT_FILENAME

/var/www/phpmyadmin$fastcgi_script_name;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;

    }

}

     }
     if (!-f $request_filename) {

        break;
     }
