Mastering NGINX - Second Edition

By: Dimitri Aivaliotis

Overview of this book

NGINX is a high-performance HTTP server and mail proxy designed to use very few system resources. But despite its power it is often a challenge to properly configure NGINX to meet your expectations. Mastering Nginx is the solution – an insider’s guide that will clarify the murky waters of NGINX’s configuration. Tune NGINX for various situations, improve your NGINX experience with some of the more obscure configuration directives, and discover how to design and personalize a configuration to match your needs. To begin with, quickly brush up on installing and setting up the NGINX server on the OS and its integration with third-party modules. From here, move on to explain NGINX's mail proxy module and its authentication, and reverse proxy to solve scaling issues. Then see how to integrate NGINX with your applications to perform tasks. The latter part of the book focuses on working through techniques to solve common web issues and the know-hows using NGINX modules. Finally, we will also explore different configurations that will help you troubleshoot NGINX server and assist with performance tuning.

In this chapter, we saw how a NGINX configuration file is built. Its modular nature is a reflection, in part, of the modularity of NGINX itself. A global configuration block is responsible for all aspects that affect the running of NGINX as a whole. There is a separate configuration section for each protocol that NGINX is responsible for handling. We may further define how each request is to be handled by specifying servers within those protocol configuration contexts (either http or mail) so that requests are routed to a specific IP address/port. Within the http context, locations are then used to match the URI of the request. These locations may be nested, or otherwise ordered to ensure that requests get routed to the right areas of the filesystem or application server.

What we did not cover in this chapter are the configuration options provided by the various modules that may be compiled into your nginx binary. These additional directives will be touched upon throughout the book...
