How to Set Up a Flask App on cPanel Shared Hosting

To set up a Flask app on cPanel shared hosting using venv and Phusion Passenger, you’ll need to follow these steps. Since you mentioned there’s no direct option for Python in the Application Manager and you only have Python 2.7 available, you’ll need to handle this manually. Here’s a step-by-step guide:

Setting up a Flask app on cPanel shared hosting using venv and Phusion Passenger requires a few manual steps. This guide will walk you through the process. Let’s assume your domain name is flaskapp.rohitchouhan.com.

For this example, we’re using a subdomain. If you’re using a subdomain, ensure it’s created before proceeding with the steps below.

Step 1: Create a Virtual Environment

1. Access Terminal

Navigate to the Terminal in your cPanel home page.

2. Navigate to Your Domain Directory in Terminal

Use the full local URL to navigate to your domain directory. Example:

cd /home1/codebp4r/flaskapp.rohitchouhan.com

3. Install Virtual Environment

Run the following commands:

pip install virtualenv
virtualenv venv

If you encounter any errors, rerun the command.

You will see a folder named venv created in your flaskapp.rohitchouhan.com directory.

Activate the virtual environment by running:

source venv/bin/activate

Finally, install Flask:

pip install flask

Step 2: Set Up Your Flask Application

1. Create Your Flask Application

In your project directory, create a file named app.py with your Flask application code. You can also copy the code from this link: https://gist.github.com/rohit-chouhan/d7297ad0565479293a92d173dbb41e4f

2. Create a `passenger_wsgi.py` File

In the same directory, create a file named passenger_wsgi.py. Copy the code from this link : https://gist.github.com/rohit-chouhan/8e5fb3ab6839bfe66b6595403845742e
