поставил python-flup nginx рабочий

сделал скрипт в дирректории
#!/usr/bin/env python
def myapp(environ, start_response):
start_response('200 OK', [('Content-Type', 'text/plain')])
return ['Hello World!\n']

if __name__ == '__main__':
from flup.server.fcgi import WSGIServer
WSGIServer(myapp).run()
в nginx

server {
listen 80;
server_name pytest;
access_log /home/www/python/adserver-access.log combined;
charset utf-8;

location / {
root /home/www/python;
fastcgi_pass unix:/home/www/python/fcgi_wsgi.socket;
fastcgi_intercept_errors off;
fastcgi_index test.py;
fastcgi_param SCRIPT_FILENAME /home/www/python$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT /home/www/python;
fastcgi_param PHP_SELF $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SERVER_NAME pytest;
fastcgi_param HTTP_HOST pytest;
fastcgi_param SERVER_PORT 80;
fastcgi_param REMOTE_ADDR $remote_addr;
}
}
но сервер отдает
502 Bad Gateway
