I'm experimenting to publish my django project with Apache mod_wsgi. I created a simple django3 project named sampleapp in virtualenv. Then, I configured my /etc/apache2/sites-enabled/000-default.conf file as follows
<VirtualHost *:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www/html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
WSGIDaemonProcess sampleapp python-home=/var/www/html/sampleapp/env python-path=/var/www/html/sampleapp:/var/www/html/sampleapp/env/lib/python3.7/site-packages
WSGIProcessGroup sampleapp
WSGIScriptAlias /sampleapp /var/www/html/sampleapp/sampleapp/wsgi.py process-group=sampleapp
</VirtualHost>
Although my virtualenv's python version is 3.7, mod_wsgi is used system's python version(3.5), so it doesn't see my virtualenv and doesn't use its python version. My apache error log as follows:

How do I configure mod_wsgi to use the python version of my venv? Or where is my fault? Thanks for the answers.
So the mod_wsgi is compiled to a specific version of Python for Apache. You cannot make it run a different version of python. You can either rebuild that mod_wsgi to the correct version, or change the virtual environment. This deletes virtualenv wrapper but keeps project files.
I think that "changing the virtualenv" would be easier.
rmvirtualenv env-name
mkvirtualenv -p python3.5 env-name
setvirtualenvproject env-name
When you use 'mkvirtualenv' use the -r tag for a requirements.txt
Or rebuild the mod_wsgi:

I deploy flask with apache on CentOS7
And I want Oracle database to insert or select when user access.
So I install cx_Oracle
pip install cx_Oracle
And run flask on virtual env.
flask run
It work with no error.
But I access to localhost:80 using apache, It occur Internal Server Error 500.

I followed this article for deploy flask with apache.
https://dev.to/sm0ke/flask-deploy-with-apache-on-centos-minimal-setup-2kb7
and install cx_Oracle and I copied it where I thought I needed it.
Here my tree
/etc/httpd/modules/
|-cx_Oracle.cpython-36m-x86_64-linux-gnu.so
|-cx_Oracle-8.0.1.dist-info
/var/www/hitme/lib/python3.6/site-packages
|-cx_Oracle.cpython-36m-x86_64-linux-gnu.so
|-cx_Oracle-8.0.1.dist-info
/usr/local/lib/python3.6/site-packages
|-cx_Oracle.cpython-36m-x86_64-linux-gnu.so
|-cx_Oracle-8.0.1.dist-info
But it still gives the error.
Is there any other way?
Ensure that the required Oracle Instant Client is installed to the Apache user by downloading
https://download.oracle.com/otn_software/linux/instantclient/199000/instantclient-basic-linux.x64-19.9.0.0.0dbru.zip
and unzip ut to a folder Apache user owns or is accessible for read and execute - lets say
/apache/oracle
After that, ensure PATH, ORACLE_HOME and LD_LIBRARY_PATH ist set properly as Apache User - i.e.
export ORACLE_HOME=/apache/oracle
export PATH=$PATH:$ORACLE_HOME
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME
If you start Apache as service then you may need to set the variables to root or user who starts apache.

I have installed flask on the virtual environment and trying to activate from the WSGI file execution. However, this is not working for me.
FYI : The commented lines on virtual host is already I have tried.
This question has been asked before here but the solution does not work for me. My python venv configuration is not playing well with the apache2 mod_wsgi and I cannot root-cause the issue. At present, I cannot comment on this question so I'm posting another one
Here are the apache2 error logs when trying to log into the site.

I referenced these instructions from DigitalOcean trying to install pgAdmin4 on Ubuntu 16.04.
Edit: I used a python3 venv instead of anaconda virtual env and everything worked fine. So the root cause is the anaconda system. There's a discussion on the mod_wsgi mailing list about this

#mod-wsgi : test
WSGIScriptAlias /test /home/service/was/test/test_app.wsgi
WSGIDaemonProcess test_app processes=4 threads=4 display-name=%{GROUP}
<Directory /home/service/was/test/ >
WSGIProcessGroup test_app
Require all granted
</Directory>
</VirtualHost>
And my wsgi script, test_App.wsgi and test_app.py:
#test_app.wsgi
import os, sys
os.environ['PYTHON_EGG_CACHE'] = '/tmp'
sys.path.insert(0, '/home/service/was/test/')
print os
print sys
from test_app import app as application
In this setting, I run test_app.py in my dev-server.
Why generate 'Target WSGI script '/home/service/was/test/test_app.wsgi' cannot be loaded as Python module.' message?
Why do not import python module installed by pip?
I am trying to run a Linux server configuration for a catalog project. I am using: Apache2, Flask, and SQLAlchemy and I had to install and configure PostgreSQL. The site I am trying to run is the Public IP Address: http://52.27.140.219/. I am happy to provide greater detail. I am new with Linux and many things discussed here, but I believe my work is strong, except for the end problem below.
Important steps in Terminal:

Don't use a relative path name to the file. Instead construct an absolute path name. This is needed because the current working directory of the process will not be where your code is located. Read:
https://code.google.com/p/modwsgi/wiki/ApplicationIssues#Application_Working_Directory
So as Graham said, eventually, you end up with something like:
APP_PATH = '/var/www/catalog/
CLIENT_ID = json.loads(open(APP_PATH + 'client_secrets.json', 'r').read())['web']['client_id']
