A step-by-step guide to configuring Passenger WSGI and running Python applications on Web Savanna server environments.

Web Savanna provides built-in Python support through cPanel’s Setup Python App tool powered by CloudLinux LVE / Phusion Passenger.

Step 1: Create the Python Environment

1. Log into cPanel.

2. Under the Software section, click Setup Python App.

3. Click Create Application.

4. Configure your application settings:

   • Python Version: Select Python 3.10 or 3.11 (recommended).

   • Application Root: Enter your application directory (e.g., myapp).

   • Application URL: Select your domain/subdomain path.

   • Application Startup File: Set to passenger_wsgi.py.

   • Application Entry Point: Set to application.

5. Click Create.

Step 2: Install Virtual Environment Dependencies

1. Copy the virtual environment activation command shown at the top of your Python App page (e.g., source /home/username/virtualenv/myapp/3.11/bin/activate).

2. Log into your account via SSH or open cPanel Terminal.

3. Paste the activation command and press Enter.

4. Install your project requirements:

   Bash

    

   pip install -r requirements.txt
   

Step 3: Restart the Application

Whenever you modify your Python scripts or update packages, return to Setup Python App in cPanel and click Restart Application to apply changes.
