配置 wsgi python

Question

im configuring my EC2 instance (amazon web services) on an ubuntu server, to test django(python)

I have python installed, and the apache server,

I have the It works! [apache] page on my url address, index.html

now im configuring the wsgi and mod_wsgi [for python and django],

im following this info to configure wsgi:

deploy python wsgi app tutorial

but when I try the Basic Hello World WSGI Configuration

import os 
import sys 

sys.path.append('/srv/www/cucus/application') 

os.environ['PYTHON_EGG_CACHE'] = '/srv/www/cucus/.python-egg' 

def application(environ, start_response):
    status = '200 OK'
    output = 'Hello World!'
    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]
    start_response(status, response_headers)

    return [output]

and go to mysite/application/application.wsgi

http://ec2-107-20-20-19.compute-1.amazonaws.com/cucus/application/application.wsgi

in my browser, i see the code for the page, but not the rendered "hello world"

what im i missing?

do I need to configure the virtual hosts for ubuntu?, even im using just one site?

thanks!

Answer 1

You need your output to be binary.

Change

output = 'Hello World!'

to

output = b'Hello World!'

Here's some simple WSGI boilerplate code I created - show's you how to manage a GET and POST request.

Answer 2

Have you read any of the actual mod_wsgi documentation or watch the presentation about it:

http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide http://code.google.com/p/modwsgi/wiki/WhereToGetHelp?tm=6#Conference_Presentations

You either never set up WSGIScriptAlias or didn't enable the site for Apache properly to read it or didn't restart Apache.

Answer 3

Try restarting Apache if that does not work then double your apache config you are enabling mod_wsgi with this line of code LoadModule wsgi_module modules/mod_wsgi.so as well as WSGIScriptAlias / /path/to/mysite/apache/django.wsgi
