How to deploy a flask application on Apache web server on Mac
By Alaina Ahuja April 27th 2020
This article explains step by step how to deploy a Python Flask application on an Apache webserver on Mac. The diagram below explains how the Apache server will work with our code:
Step #1: Installing Flask
Type this command in your terminal to install flask:
Step #2:
Installing mod_wsgi
Type this command in your terminal to install mod_wsgi :
Step #3:
Creating a flask application
Create a .py file for your flask application. Let's name it "Hello_Flsk.py". We also need to make a folder for this file(I named mine "Alaina_Code"). Now enter the following code into your .py file:
Step #4:
Creating a WSGI file
Make Sure Your .py and .wsgi files are both in the same folder
In order for the Apache server to understand the code in Hello_Flsk.py, we need to make a .wsgi file. Let's name this file Flsk_Config.wsgi. Put this file in the folder we made in the last step and enter in the following code:
Here, instead of '/Alaina_Code/FlaskFirstAPI' you would enter the folder path where you are keeping your .py and .wsgi files.
Step #5:
Editing and working with httpd.conf
We finally need Apache to recognize the WSGI file We wrote. Apache's config file(httpd.conf) should be available at this at this path:'/etc/apache2' open it and enter in the following:
Make sure to double-check if this .so file is on your computer. If it isn't, mod_wsgi wasn't installed correctly.
Now, you should be able to run your program. To test it, type into your browser:
​
http://localhost/flasktest/Hello
​
You should get a message like this:
If you're having trouble getting to httpd.conf, you can right-click on finder, and choose the option "go to folder". There, if you enter the path, you can find any hidden folders that may not be visible otherwise. For a more detailed description, see this article:
