What is Nginx?
Nginx is a high-performance web server, reverse proxy, and load balancer. It is known for its stability, rich feature set, simple configuration, and low resource consumption. Nginx is often used to serve static content, as a reverse proxy for application servers, and to handle TLS termination and load balancing.

Frequently Asked Questions
Where do I put the generated config file?
Save it in /etc/nginx/sites-available/your-domain.conf, then create a symlink: sudo ln -s /etc/nginx/sites-available/your-domain.conf /etc/nginx/sites-enabled/. Run sudo nginx -t to test, then sudo systemctl reload nginx.
Are the configs production-ready?
They provide a solid starting point. For production, review the settings, adjust timeouts and buffer sizes for your workload, and ensure SSL certificates are properly configured.
How do I test my Nginx config?
Run sudo nginx -t to validate the syntax. If it reports "syntax is ok" and "test is successful", reload Nginx with sudo systemctl reload nginx.
What's the difference between a reverse proxy and a regular proxy?
A reverse proxy sits in front of web servers and forwards client requests to the appropriate backend. It hides the backend servers from the client and can provide load balancing, caching, and SSL termination. A forward proxy (regular proxy) sits in front of clients.
