Hello,
I've spent a fair bit of time diagnosing this particular issue with
Apache/mod_wsgi and could use some pointers. Any help is extremely
appreciated.
*Versions*
- Ubuntu 14.04.6 LTS
- Python 2.7.8
- Python 3.6.8
- mod-wsgi 4.3.2 (installed via pip)
*Virtualenvs*
- /home/release/envs/stage-python2.7
- /home/release/envs/stage-python3.6
Depending on which version of python I want this instance to use, a symlink
is created at /home/release/envs/stage that maps to either of the
virtualenvs above. In this example, I am simply trying to get it working
with python 2.7.

In this case, /home/release/envs/stage is a symlink to a python2.7
virtualenv:

bin/python --version
Python 2.7.8
ryanwest@el8-stage-experimental-webapp1:/home/release/envs$ stage-python3.6/
bin/python --version
Python 3.6.8
I realize that pointing python-home to the bin directory is strange. When I
point it to simply /home/release/envs/stage, the apache error logs default
to saying python home is /usr/bin/python. As a side note, my Apache logs
don't seem to be providing me with many pertinent details. I have tried
increasing the verbosity using LogLevel debug with no success.
What am I doing wrong? Thank you!
Ryan
