Install Apache mod_wsgi Module on Ubuntu 18.04

Ubuntu

The mod_wsgi Apache module is used for serving Python scripts over HTTP via Apache web server. This tutorial helps you to how to install Apache mod_wsgi module on Ubuntu 18.04 (Bionic Beaver).

Step 1 – Prerequisites

Login to Ubuntu 18.04 server console via SSH and install some prerequisites packages on the system.

sudo apt-get update
sudo apt-get install python libexpat1

Step 2 – Install mod_wsgi Module

Before starting, you will need to install some prerequisite Apache components in order to work with mod_wsgi. You can install all required components by simply running the following command:

sudo apt-get update
sudo apt-get install apache2 apache2-utils ssl-cert

Now, install mod_wsgi Apache module by running the following command:

sudo apt-get install libapache2-mod-wsgi

Restart Apache service to get mod_wsgi to work.

sudo systemctl restart apache2

Step 3 – Configure Apache for WSGI

Next, create a python script to serve via mod_wsgi Apache module.

sudo vi /var/www/html/wsgi_test_script.py

Add the following content:

def application(environ,start_response):

status = '200 OK'

html = '<html>n'

'<body>n'

' Hooray, mod_wsgi is workingn'

'</body>n'

'</html>n'

response_header = [('Content-type','text/html')]

start_response(status,response_header)

return [html]

 

After that, you need to configure Apache server to serve this file over HTTP protocol. Let’s create a configuration file to serve wsgi_test_script.py script over a sub URL.

sudo nano /etc/apache2/conf-available/mod-wsgi.conf

Add the following content:

WSGIScriptAlias /test_wsgi /var/www/html/wsgi_test_script.py

After completing the above steps enable mod-wsgi configuration and restart Apache service.

sudo a2enconf mod-wsgi
sudo systemctl restart apache2

Step 4 – Testing

The setup is ready now. You can test the script by accessing http://SERVER_IP//test_wsgi URL in a web browser. See below screenshot:
