Description: There is a Python WSGI web application file at /home/admin/wsgi.py , the purpose of which is to serve the string “Hello, world!”. This file is served by a Gunicorn server which is fronted by an nginx server (both servers managed by systemd).
So the flow of an HTTP request is: Web Client (curl) – Nginx – Gunicorn – wsgi.py . The objective is to be able to curl the localhost (on default port :80) and get back “Hello, world!”, using the current setup.
