Hi

I have been playing with wsgi on my apache 2.4 server and have noticed that the environment variables I am seeing in apache do not seem to be inherited from the shell in which I start apache - which is what I expected.
I initially put this query out on linux questions - see https://www.linuxquestions.org/questions/linux-software-2/how-can-i-debug-resolve-inconsistencies-in-wsgi-python-environment-4175721339/, but thus far have not been pointed to an explanation, so was wondering if anyone on this forum knew anything about how the environment variables are determined at runtime.

I run apache from the command line like this:

Code:

$ apachectl start

And the httpd processes are run as apache user, which is a nologin user.

Does anyone know how the environment variables are determined when I do this (I have specifically been looking at PATH and PYTHONPATH) ?

As noted in the above link I can explicitly set these in /etc/sysconfig/httpd, but I would like to understand where the defaults are coming from.
