mod_wsgi: Problem to "deploy" using mod_wsgi on windows server 2019 local network.

I’ve been trying to put my django application in production for weeks and I got this situation:

Apache Lounge Version 2.4
Python 3.11
Error log:

I don’t know where else to go, I’m using ApacheLounge after reading your recommendation in another post.

Those last of logs with the exception traceback do not show any output that I can see corresponding to the lines:

import sys
print(sys.path)

which I told you to add. Were they added?

To make it more obvious, change it to:

import sys
print("PATH:", sys.path)

Ensure these two lines are the very first lines in the wsgi.py file.

Using your web browser go to the same URL you have been using to try and access the application. The output of any print() statements in the wsgi.py should be displayed in the Apache error log if things are set correctly in the Apache config.

So did you try and access your web site or not?

Also ensure that LogLevel is set to info and not err or warn so can see when mod_wsgi loads the wsgi.py. That will confirm you actually made a request and it was received properly.

You need to make a request to the WSGI application else you will not see the message as the wsgi.py file will only be loaded when first request arrives. You may need to restart the Apache service as well if how things are setup means the wsgi.py has been cached in memory.

At the very start of the wsgi.py file, before any imports, add:

import sys
print(sys.path)

What is the value for sys.path that is printed out into the logs?

My mistake, I just copied what you had, which was in part wrong to start with ignoring the path issue.

Use:

WSGIPythonPath "C:/Apache24/htdocs/Cadastro/projeto_cad_usuarios"

It should only be given one argument.

At a guess you should have:

WSGIPythonPath / "C:/Apache24/htdocs/Cadastro/projeto_cad_usuarios"

You had it pointing at the wrong directory.

It should point to the parent directory of where your project is, not the project directory itself.
