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.

Configuring advanced logging

Under normal circumstances, we want logging to be as minimal as possible. Usually, what's important is which URIs were called by which clients and when, and if there was an error, to show the resulting error message. If we want to see more information, this leads into a debug logging configuration.

Debug logging

To activate debug logging, the nginx binary needs to have been compiled with the --with-debug configure flag. As this flag is not recommended for high performance production systems, we may want to provide two separate nginx binaries for our needs: the one that we use in production, and the one that has all the same compile-time flags (options given to the configure script), with the addition of --with-debug so that we may simply swap out the binary at runtime in order to be able to debug.

Switching binaries at runtime

NGINX provides the capability to switch out binaries at runtime. After having replaced the nginx binary with a different one, either because...
