mod_wsgi is a useful Apache module that allows you to host Python applications in Apache web server. It supports Python WSGI interface making it suitable for running high-performance production sites in Apache. Here’s how to install mod_wsgi on Ubuntu.


How to Install mod_wsgi on Ubuntu

Here are the steps to install mod_wsgi on Ubuntu.


1. Install prerequisites & update packages

Log into your Ubuntu server via SSH or open a terminal window and paste the following commands to update system packages, and install python

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


2. Install mod_wsgi module

You need to install some dependencies before you can install mod_wsgi. Here are the commands to install them

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

If they are already installed on your system, Ubuntu will simply skip their installation.

Install mod_wsgi

$ sudo apt-get install libapache2-mod-wsgi


3.  Restart Apache Server

Restart Apache server to apply changes

$ sudo systemctl restart apache2


4. Configure mod_wsgi for Apache

Let’s create a sample python script to run within Apache via mod_wsgi. Create a blank new python file

$ sudo vi /var/www/html/


Paste the following lines. Please ensure they are properly indented as shown. Otherwise, python will give en error.

def application(environ,start_response):
 status = '200 OK'
 html = '<html>\n' \
  '<body>\n' \
  ' Hooray, mod_wsgi is working\n' \
  '</body>\n' \
 response_header = [('Content-type','text/html')]
 return [html]


Save and close the file


Next, we need to create a config file to serve this python script over mod_wsgi. Open mod_wsgi’s config file in a text editor.

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


Add the following line:

WSGIScriptAlias /test_wsgi /var/www/html/

Save and close the config file


Run the following commands to enable mod_wsgi

$ sudo a2enconf mod-wsgi
$ sudo systemctl restart apache2



5. Test mod_wsgi

Open your web browser and go to http://your_server_ip/test_wsgi. Replace your_server_ip with your server’s ip or domain name

install mod_wsgi on ubuntu


That’s it! You have installed mod_wsgi on Ubuntu.
