Flask App Deployment on Alma Linux 9 With nginx

 

1. Use Gunicorn + Nginx for Each Flask App

• Gunicorn is a WSGI server that efficiently runs Flask applications.
• Nginx acts as a reverse proxy to route traffic to the correct Flask application.

2. Use Separate Virtual Environments

• Keep each Flask app isolated using venv.

3. Configure Systemd for Process Management

• Run each Flask app as a systemd service.

4. Use Nginx to Host Multiple Domains

• Set up separate server blocks (virtual hosts) in Nginx.
