Introduction
Welcome to our guide on how to install Python on an Apache server. Python is an open-source programming language that has become increasingly popular within the developer community. It is used for a variety of purposes such as web development, data analysis, and artificial intelligence. Apache is one of the most popular web servers in use today, known for its versatility and security.
This guide will take you through the process of installing Python on your Apache server, why it is important to do so, and the advantages and disadvantages of using Python with Apache. Within this guide, we aim to provide an in-depth understanding of Python within the context of Apache, allowing you to make informed decisions when developing your next project.
Before we get started, it is essential to understand that this guide assumes that you are familiar with using an Apache server. We will not be covering the basics of setting up an Apache server in this guide.
Why Install Python on Apache Server?
Python and Apache are both open-source software and a popular choice among developers. Installing Python on an Apache server allows you to run Python scripts from within the Apache environment. This integration enables Apache to handle Python web applications without deploying a separate Python web server. This integration provides a seamless user experience while optimizing performance.
The Apache server is widely used in the industry, and integrating Python with Apache can bring additional benefits such as load balancing and scalability. It provides a flexible environment to host Python applications, making it an excellent choice for web developers.
How to Install Python on Apache Server
Before installing Python on an Apache Server, ensure that you have administrative access to the server. If you do not have administrative access, please contact your system administrator to install Python on your behalf.

Step 1: Update the Server
Before starting, ensure that your server software is up to date. This will minimize the chances of encountering compatibility issues when installing Python and Apache. To update your server, follow the steps below:
Step 1.1: Open a terminal window and enter the command below to update the package list:
sudo apt-get update
Step 1.2: Enter the command below to install the updates:
sudo apt-get upgrade
Step 2: Install Python
Python is typically not installed by default on a server, so you will need to install it manually. Experienced users can use their preferred method, but we will use the apt package manager in this guide. To install Python, execute the following commands in the terminal:
Step 2.1: Enter the command below to install Python:
sudo apt-get install python3
Step 3: Install Apache
Apache is a popular web server used worldwide. Apache2 package can be installed with the following command:
Step 3.1: Enter the command below to install Apache:
sudo apt-get install apache2
Step 4: Install mod_wsgi
mod_wsgi is Apache’s module that provides support for running Python web applications. You can install mod_wsgi using apt-get:
Step 4.1: Enter the command below to install mod_wsgi:
sudo apt-get install libapache2-mod-wsgi-py3
Step 5: Configure Apache to Run Python Scripts
To configure Apache to run Python scripts, you need to create a new virtual host configuration file. The virtual host file is responsible for directing requests to your Python application. Follow the steps below to create a virtual host:
Step 5.1: Create a new configuration file for your virtual host by entering the following command:
sudo nano /etc/apache2/sites-available/your-domain.com.conf
In the above command, replace “your-domain.com” with your actual domain name.
Step 5.2: Paste the following configuration into the file. Replace ‘/var/www/your-app’ with the actual path to your Python application’s root directory:
<VirtualHost *:80>ServerName your-domain.comServerAlias www.your-domain.comWSGIDaemonProcess your-app python-home=/var/www/your-app/venv python-path=/var/www/your-appWSGIProcessGroup your-appWSGIScriptAlias / /var/www/your-app/app.wsgi<Directory /var/www/your-app>Require all granted</Directory>ErrorLog ${APACHE_LOG_DIR}/error.logCustomLog ${APACHE_LOG_DIR}/access.log combined</VirtualHost>
Step 5.3: Save the file and exit the editor.
Step 5.4: Enable the virtual host by entering the command below:
sudo a2ensite your-domain.com.conf
Step 5.5: Reload Apache for the changes to take effect:
sudo service apache2 reload
Step 6: Test the Installation
You can now test the installation by creating a new Python script in your application directory. Open your preferred text editor and create a new file with a .py extension. Copy the sample code below into the file:
def application(environ, start_response):"""Sample application"""response_body = 'The request method was %s' % environ['REQUEST_METHOD']status = '200 OK'response_header = [('Content-Type', 'text/plain'),('Content-Length', str(len(response_body)))]start_response(status, response_header)return [response_body.encode('utf-8')]
Save the file as ‘hello.py’ and place it in the root directory of your application. Next, create a new file named ‘app.wsgi’ in the same directory with the following code:
#!/usr/bin/pythonimport syssys.path.insert(0, '/var/www/your-app')from hello import application as app
Save the file and use the following command to start the server:
sudo service apache2 start
