Super basic uwsgi configuration

Question

I've tried some uwsgi tutorials but can't get a simple python script to run in my browser. Ive read through this (http://uwsgi-docs.readthedocs.org/en/latest/WSGIquickstart.html) and this (https://www.digitalocean.com/community/articles/how-to-deploy-python-wsgi-applications-using-uwsgi-web-server-with-nginx) and others, but for some reason can't get a simple uwsgi app running. I am currently not going through a web server, just uwsgi by itself.

I have the following wsgi.py:

def application(env, start_response):
    start_response('200 OK', [('Content-Type', 'text/html')])
return ["Hello!"]

and I run:

uwsgi --socket 127.0.0.1:8080 --chdir /my/program/path --pp .. -w wsgi

which produces the following output (looks promising):

*** Starting uWSGI 2.0.3 (64bit) on [Mon Apr 14 12:51:32 2014] ***

but when I go to port 8080 from my browser I get a "could not connect" error. Port 8080 is open and has been tested.

I've also tried the following wsgi.py:

import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

exactly the same results

If you want to run uWSGI without a web server in front of it, use http option instead of socket. See Native HTTP support.

Also, use 0.0.0.0:80 as an address if you are accessing from a remote machine.
