How to Deploy Python App on Shared Hosting

You can run a small Flask or Django app on Domain India shared hosting: the cPanel and DirectAdmin servers have a Python application tool that creates a virtual environment for your app and serves it on your domain. This guide shows how to set it up, what to watch for, and when the App Platform or a VPS is the better choice.

1. What we measured on our servers

We checked the shared servers on 23 September 2026:

Choose the newest version your app supports. Python 2.7, 3.8 and 3.9 no longer receive security fixes, so do not start a new project on them. Your app runs behind the Apache web server through Phusion Passenger, which loads it as a WSGI application.

2. Is shared hosting right for your app?

If your app hits the account's limits, visitors see errors such as 503 or 508. See Understanding hosting resource limits.

3. Create the app in cPanel

Environment variables such as SECRET_KEY or DJANGO_SETTINGS_MODULE go in the Environment variables section of the same page. Save, then restart.

4. The passenger_wsgi.py file

Passenger looks for a variable called application in your startup file.

Flask, with your app object in app.py:

import os
import sys

sys.path.insert(0, os.path.dirname(__file__))

from app import app as application

Django, with your project package called mysite:

import os
import sys

sys.path.insert(0, os.path.dirname(__file__))
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

For Django, also set ALLOWED_HOSTS to your domain, set DEBUG = False, and run collectstatic so that your static files are served from a folder inside your website's document root.

5. Databases

Your hosting account includes MySQL-compatible databases that you create in the control panel. Connect to them from your app on localhost; install a driver such as PyMySQL or mysqlclient in the app's environment. Port 3306 is closed from outside, so use an SSH tunnel if you need to reach the database from your own computer. See How to connect to the MySQL database.

6. DirectAdmin

DirectAdmin has the same CloudLinux Python selector, installed as a plugin, with the same fields: version, application root, URL, startup file and entry point. Menu names can differ between DirectAdmin skins; if you cannot find the Python option, ask support.

7. Using SSH (optional)

Jailed SSH access is available on every shared hosting plan (cPanel, DirectAdmin, Webuzo). It is off by default; ask support to enable it for your account. See Enabling and accessing jailed SSH.

With SSH on, the app page shows the command that enters your app's virtual environment, for example:

source /home/USERNAME/virtualenv/myapp/3.12/bin/activate && cd /home/USERNAME/myapp
pip install -r requirements.txt
python manage.py migrate

Tools available inside the jailed shell vary by server, so check with support before you rely on one. Restart the app from the panel after each change.

8. Troubleshooting

• The page shows an error or "Web application could not be started": check passenger_wsgi.py for typos and confirm the entry point is application. Restart after every fix.
• ModuleNotFoundError: the package was installed outside the app's environment. Run Run Pip Install again, or activate the environment first when using SSH.
• A package fails to build: some packages need system libraries that shared hosting does not provide. Choose a version with a prebuilt wheel, or use the App Platform or a VPS.
• Changes do not show: restart the app. cPanel can serve a cached copy of a page for up to 120 minutes, so add ?t=1 to the URL to check.
• Background tasks (Celery, schedulers) stop: shared hosting runs your app to answer web requests. Use a VPS for workers.

9. Where Python apps run best at Domain India

For a production Python app, the App Platform is the dependable route. You run Python there from your own Dockerfile, deploy from GitHub or with a deploy token, and get a PostgreSQL database and SSL with each plan. It has no SSH or root access. See Getting started with the App Platform.

For root access, Celery workers, Uvicorn or any system package, choose a VPS.
