I am on a PC running Windows 10. I am in the early stages of learning
python and flask for web development purposes and I want to set up a local
development environment. I have been using wamp for php development and
have a successful installation of wampserver 3.0.6 64bit which runs Apache
2.4.23. I now want to use that for python/flask and the way to do that
appears to be via mod_wsgi. Thanks to an exchange with Graham Dumpleton in
Stackoverflow I am aware of the documentation for mod_wsgi and have read
that but clearly I have not fully understood it or complied with it
correctly and the system isn't working.
Incidentally I have managed to get a VirtualEnvironment working which I
think uses an inbuilt python server but I don't think that solves the
problem of connecting to a database.
Anyway this is what I have done so far:
1. Successfully installed Python 3.6
2. Successfully installed flask (evidence for which is that the
VirtualEnvironment works)
3. Successfully (I think) installed mod_wsgi via 'pip install mod_wsgi'
4. Run command 'mod_wsgi-express module-config' and copied the output to my
apache httpd.conf file.
5. Changed the httpd.conf LogLevel to 'info'
6. Commented out the line 'AddHandler cgi-script .cgi .py'
7. Created simple wsgi application (copy/paste from documentation), called
'test.wsgi' in a folder C:\wamp\www\wsgi_script
8. Set up a virtual host in the httpd-vhosts.conf file using the following
code:
<VirtualHost *:80>
ServerName localhost
WSGIScriptAlias /test C:/wamp/www/wsgi_script/test.wsgi
<Directory C:/wamp/www/wsgi_script>
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
which I expect may be wrong but I don't understand it enough to know
what.
9. Run a check on the server via 'C:\wamp\bin\apache\apache2.4.23\bin>httpd
-V'
which seemed to give a satisfactory response showing the version as 2.4.23
and the MPM as WinNT.
10. In the browser (Firefox) entered following in url bar
'http://localhost/wsgi_script/test.wsgi'. The output is merely the raw code
of the file.
There are things I expected to happen that didn't eg
After installing mod_wsgi, I expected a module 'mod_wsgi.so' to appear in
the apache modules folder but it did not.
I expected to have to load that module via a LoadModule line in httpd.conf
but didn't see any advice to that effect.
When I look at the containing fiolder in the browser ie
'http://localhost/wsgi_script/' I see the 'index of' page at the bottom of
which is
Apache/2.4.23 (Win64) PHP/5.6.25 mod_wsgi/4.5.17 Python/3.6 Server at
localhost Port 80
which seems to indicate that apache is recognising mod_wsgi
Having tried to access the wsgi file, the apache error log read:

I hope this is enough information to pick up my errors and suggest
corrections or further tests.
