Installation of mod_wsgi on Windows.

Install

Windows

Download apache_2.0.61-win32-x86-no_ssl.msi from http://httpd.apache.org/download.cgi.

Note: We use Apache 2.0 for Trac because the python bindings have “not seen much testing”: Windows Apache 2.2.x
Install Apache. I installed to:
```
c:\tools\
```
Note: This install Apache to C:\tools\Apache2\.
Test by browsing to http://localhost/

mod_wsgi (Linux)

sudo apt-get install libapache2-mod-wsgi

mod_wsgi (Windows)

Download mod_wsgi.so from http://adal.chiriliuc.com/mod_wsgi/.

I downloaded from this folder, http://adal.chiriliuc.com/mod_wsgi/revision_726_2.0c4/mod_wsgi_py25_apache20/ (The latest revision for python 2.5 and Apache 2.0).

Copy mod_wsgi.so to the Apache modules folder.

On my workstation:

copy \download\apache\mod_wsgi.so \tools\Apache2\modules\

Load the wsgi module.

Edit the Apache configuration file, conf/httpd.conf and add:
```
LoadModule wsgi_module modules/mod_wsgi.so
```
If you want to, change the logging level:
```
LogLevel info
```
Restart Apache.

Check the logs/error.log file. It should contain some references to python and WSGI…

Test

Create a folder to contain your WSGI applications. I created:
```
C:\repository\apache\python\wsgi\
```

Create the python script my-wsgi-app.wsgi in this folder. Here is the script:

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]

Edit conf/httpd.conf and add one of the following:

For a single application:

WSGIScriptAlias /myapp "C:/repository/apache/python/wsgi/my-wsgi-app.wsgi"
<Directory "C:/repository/apache/python/wsgi">
  Order allow,deny
  Allow from all
</Directory>

The following URL should run the application: http://localhost/myapp

To run multiple applications from a folder:
WSGIScriptAlias /wsgi/ "C:/repository/apache/python/wsgi/" <Directory "C:/repository/apache/python/wsgi"> Order allow,deny Allow from all </Directory>
Allows access to multiple application in a folder. In this example, the url http://localhost/wsgi/my-wsgi-app.wsgi will run our test application.
