Overview of this book

<p>Nginx is a lightweight HTTP server designed for high-traffic websites, with network scalability as the primary objective. With the advent of high speed Internet access, short loading times and fast transfer rates have become a necessity. This free, open source solution will either come as a full replacement of other software such as Apache, or stand in front of your existing infrastructure to improve its overall speed.</p> <p>"Nginx HTTP Server - Second Edition" provides a detailed guide to setting up Nginx in different ways that correspond to actual production situations: as a standalone server, as a reverse proxy, interacting with applications via FastCGI and more. In addition, the complete directive reference will be your best friend at all stages of the configuration and maintenance processes.</p> <p>This book is the perfect companion for both Nginx beginners and experienced administrators. For beginners, it will take you through the complete process of setting up this lightweight HTTP server on your system and configuring its various modules to get it to do exactly what you need, in a fast and secure way. For more experienced administrators, this book provides different angles of approach that can help you make the most of your current infrastructure. Nginx can be employed in many situations, whether you are looking to construct an entirely new web-serving architecture or simply want to integrate an efficient tool to optimize your site loading speeds.</p> <p>This book takes you through the setup and configuration of Nginx by detailing every step of the way, from downloading to configuring your server in a selection of common architectures.</p>

  • Basic address and port information on the backend server

  • Caching, buffering, and temporary file options

  • Limits, timeout, and error behavior

  • Other miscellaneous options

All these options are available via directives which we will learn to configure throughout this section.

Main directives

The first set of directives will allow you to establish basic configuration such as the location of the backend server, information to be passed, and how it should be passed.
