Flask app on Fedora with Apache

I have a DO droplet running Fedora with Apache currently configured as a webserver. I need to deploy my simple python app with Flask and Apache. So far I have tried using mod_wsig, and deployment is (predictably) far from simple.

I have got Apache on my server, and it is using https with LetsEncrypt.

I have made a hello-world Flask app that runs on a development server.

I followed the instructions at https://pypi.org/project/mod-wsgi/ and installed mod-wsgi into a python virtual environment. I found the directives needed to configure Apache by running mod_wsgi-express module-config and put then into the .conf file that modifies the httpd.conf file. (I have created a ‘sites-enabled’ folder that links with a ‘sites-available’ folder)

After that, I was at a loss at what to do, so I have followed https://medium.com/@cdanielmedinas/deploying-your-first-flask-application-on-apache-wsgi-linux-server-fb54537aef41. I have run into problems on issues the tutorial did not cover.

Some I have fixed. Like understanding permissions. Which I think I have fixed by adding the user that is running Apache (as specified in the httpd.conf file) to have execute permissions on the files and folders on the flask app. Also, I am not sure why the tutorial seemed to not mount the project folder using Alias /project/ /srv/http/your_project . When I did this, it seemed to fix the “AH01630: client denied by server configuration” problem I had.

Of course there is some more troubleshooting to be done. There seems to be a problem with the .wsgi file as it was suggested to be written in that tutorial I had been following.

Activating the virtual environment by running some activate_this.py file like that tutorial suggests does not seem to work. Now here is the question: Should I remove that section because the virtual environment should be activated in the .conf file that modifies the httpd.conf file by writing WSGIDaemonProcess application_name python-home=/path/to/app/venv within my .conf file? (https://stackoverflow.com/questions/42661771/how-to-get-mod-wsgi-to-pick-up-my-virtualenv) (Note that I cannot install libapache2-mod-wsgi-py3 like the solution to the stackoverflow question suggests because I am deploying this app on Fedora.) What should the .wsgi file contain if not that?

I guess the problem is that I haven’t been able to come across a comprehensive guide to deploying a flask app with Fedora+Apache+mod_wsgi that I could make work.

What my question comes down to is this:

1. What do we put in the .wsgi file in the Flask+Apache+mod_wsgi (when mod_wsgi is installed in the .venv using pip) scenario?
2. Has anyone written a guide to this particular deployment setup where the Apache configuration process is explained and follows recommendations from the docs?
