NGINX Crash Course 2026 | Web Server & Reverse Proxy with Projects | Hindi
In this hands-on guide, we take our NGINX knowledge further by learning how to serve multiple production applications simultaneously using NGINX as a powerful Reverse Proxy. Whether you are running AI apps, Node.js services, or Python backends on different ports, this is the real-world workflow every DevOps Engineer must master.

This video is part of the DevOps Molvi Hindi NGINX Crash Course, designed to give you practical, production-grade experience managing multiple live applications behind a single NGINX server.
🚀 In this Hands-on Lab, we cover:
🔥 Multiple Apps on One Server: How to serve different production applications running on ports like 3000, 4000, or 8000, all through a single NGINX server.
🔥 Separate Config Files: Creating and organizing individual NGINX configuration files inside /etc/nginx/sites-enabled for a clean, production-ready setup.
🔥 Reverse Proxy Deep Dive: How NGINX intercepts incoming traffic and forwards it to the correct backend application using proxy_pass.
🔥 NGINX Headers Explained: Understanding different types of headers in NGINX config files — proxy headers, custom headers, and security headers.
🔥 Serving Multiple AI Apps: A real-world demo of multiple AI applications running on different ports, each served cleanly through NGINX.
🔥 SSL, Let's Encrypt & Certbot: What SSL certificates are, how Let's Encrypt works as a free certificate authority, and the final certbot command to install free HTTPS on any domain.
Whether you are hosting multiple microservices, managing AI applications, or building a multi-tenant platform, mastering NGINX reverse proxy configuration is a non-negotiable DevOps skill.
🛠️ Key Technical Terms Covered:
Reverse Proxy
proxy_pass
/etc/nginx/sites-enabled
NGINX Server Blocks
Proxy Headers / Custom Headers
Let's Encrypt
SSL / TLS Certificate
Certbot
💡 Practice Tip: After following along, try adding a third application on port 5000 and create its own separate config file in /etc/nginx/sites-enabled. Then run certbot to secure it with a free SSL certificate — that is the complete production workflow!
