Nginx configuration
location / {
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_script_name;
fastcgi_pass 127.0.0.1:9002;
}

To serve static files add this:
    location /static/ {
root /path/to/www;
if (-f $request_filename) {
rewrite ^/static/(.*)$  /static/$1 break;
}
}

Note: the address and port may be different.
Spawn-fcgi
You can start a process with:
spawn-fcgi -d /path/to/www -f /path/to/www/index.py -a 127.0.0.1 -p 9002

Start and shutdown script
Start:
#!/bin/sh
spawn-fcgi -d /path/to/www -f /path/to/www/index.py -a 127.0.0.1 -p 9002

Shutdown:
#!/bin/sh
kill `pgrep -f "python /path/to/www/index.py"`

Note: You're free to choose which address, port, directory and filename to use, but be sure to adjust the Nginx configuration.
Hello world!
Save the following code in your www directory and call the file index.py (or whatever you like). The following line is required: web.wsgi.runwsgi = lambda func, addr=None: web.wsgi.runfcgi(func, addr).
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import web
urls = ("/.*", "hello")
app = web.application(urls, globals())
class hello:
def GET(self):
return 'Hello, world!'
if __name__ == "__main__":
web.wsgi.runwsgi = lambda func, addr=None: web.wsgi.runfcgi(func, addr)
app.run()

Note: make your file executable by doing chmod +x index.py. You'll get errors if it isn't executable.
Run
   1. Start a process with spawn-fcgi.
   2. Start Nginx.
To check if it runs do ps aux | grep index.py or simply visit the page in your browser.
To reload your configuration:
/path/to/nginx/sbin/nginx -s reload

And to stop:
/path/to/nginx/sbin/nginx -s stop
