In Detail
Nginx is an open source and cross-platform reverse proxy server designed for low memory usage and high performance and concurrency.
This book provides both basic and in-depth knowledge to help you effectively solve challenges with Nginx, or comfortably go through a transition period when switching to Nginx.
Starting with the basics, you will learn by example how to set up, configure, and operate an Nginx installation and use features of Nginx to elegantly solve challenges you experience every day when running your website. You will learn to use the rewrite engine to solve day-to-day tasks and be able to configure access restrictions in Nginx. You will also be able to manage inbound traffic using a number of Nginx features and use Nginx for load balancing and fault-tolerance features. Finally, you will learn how to solve common performance problems and apply a number of performance-tuning strategies.
Through easy exploration of the most intricate topics, this book aims to bring you to the next level in your Nginx experience.
attacker. Nginx has an elegant solution for this problem in the form of the try_files directive. The try_files directive takes a list of files and a location as the last argument. Nginx tries specified files in consecutive order and if none of them exists, it makes an internal redirect to the specified location. Consider the following example: location / { try_files $uri $uri/ @proxy; } location @proxy { proxy_pass http://backend; } The preceding configuration first looks up a file
until either the cache item is populated or the lock timeout expires. The lock timeout can be specified using the proxy_cache_lock_directive directive. If higher availability of the cache is required, you can configure Nginx to reply with stale data when a request refers to a cached item. This is very useful when Nginx acts as an edge server in a distribution network. The users and search engine crawlers will see your web site available, even though the main site experiences connectivity

use, be prepared to sort out challenges such as dependency maintenance, distribution, and application of security patches. In this section, we will be referring to the configuration script. Configuration script is a shell script similar to one generated by autoconf, which is required to properly configure the Nginx source code before it can be compiled. This configuration script has nothing to do with the Nginx configuration file that we will be discussing later. Downloading the Nginx source
