Flask

1. SSH to Your Server

ssh root@<server-ip>

2. Find Login Credentials

• Default user: flask
• Password stored in: /root/.cloudzy-creds

(Optional) Change the default password: passwd flask

3. Switch to the App User

su - flask

4. Deploy Your App

A sample Flask app is already running and accessible at: http://<server-ip

To deploy your own app:

1. Navigate to your application directory (or clone a new project): cd ~/flask_app
2. (Optional) Replace default app: git clone <your_repo_url> .
3. Activate the virtual environment: source venv/bin/activate
4. Install required packages: pip install -r requirements.txt
5. Make sure your WSGI entry point is named wsgi.py and contains: from your_module import app as application
6. Restart Gunicorn to apply changes: sudo systemctl restart gunicorn

5. Access Your App

Your Flask app is available at: http://<server-ip

Nginx is reverse-proxying requests to Gunicorn via Unix socket.

6. Change Port or Domain?

To adjust domain, port, or add SSL:

1. Edit Nginx site config: sudo nano /etc/nginx/sites-available/gunicorn
2. Test configuration: sudo nginx -t
3. Reload Nginx: sudo systemctl restart nginx
