NGINX Fundamentals

Build fast, reliable, and secure web servers with NGINX-even if you are starting from scratch.

NGINX is trusted worldwide for serving websites, routing application traffic, improving performance, and handling large numbers of simultaneous connections. However, its configuration system can feel confusing when you are new to web server administration.

NGINX Fundamentals: Building High-Performance Web Servers from Scratch provides a practical, step-by-step path from your first installation to a production-ready server. Instead of presenting isolated commands and unexplained configuration snippets, this book teaches you how NGINX works, why each setting matters, and how to make changes safely.

You will begin with the foundations of web servers and NGINX's high-performance architecture. From there, you will prepare a Linux environment, install NGINX on popular distributions, manage its services, and understand its processes, directories, contexts, directives, and configuration files.

Through clear explanations and hands-on examples, you will learn how to:

• Install NGINX on Ubuntu, Debian, CentOS, RHEL, Rocky Linux, and other distributions
• Compile NGINX from source when greater control is required
• Start, stop, restart, and reload NGINX safely with systemd
• Understand nginx.conf, configuration contexts, directives, inheritance, and include files
• Create server blocks and host static websites
• Configure document roots, index files, domain names, and custom error pages
• Understand server selection and location-matching rules
• Create redirects and rewrite URLs correctly
• Configure NGINX as a reverse proxy for application servers
• Forward headers and preserve the real client IP address
• Work with TCP ports, Unix sockets, timeouts, and proxy buffers
• Tune worker processes, connections, file handling, compression, caching, and keepalive
• Install SSL certificates and enable HTTPS
• Strengthen TLS security and redirect HTTP traffic to HTTPS
• Protect resources with authentication, IP restrictions, and request limits
• Host multiple websites on one server
• Read access and error logs, monitor performance, and diagnose common problems
• Prepare an NGINX configuration for production deployment

The book also includes useful appendices covering essential Linux commands, frequently used NGINX directives, and solutions to common error messages-giving you practical references you can return to whenever you manage a server.

This guide is written for beginners, developers, aspiring system administrators, website owners, DevOps learners, and anyone who wants to understand NGINX without being overwhelmed by unnecessary complexity. Basic command-line familiarity is helpful, but no previous NGINX experience is required.

By the end of the book, you will be able to install, configure, secure, optimize, deploy, and troubleshoot an NGINX web server with confidence.
