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>

Install issues


There are typically four sources of errors when attempting to install Nginx or to run it for the first time:

  • Some of the prerequisites are missing or an invalid path to the source was specified. More details about prerequisites can be found in Chapter 1, Downloading and Installing Nginx.

  • After having installed Nginx correctly, you cannot use the SSL-related directives to host a secure website. Have you made sure to include the SSL module correctly during the configure step? More details in Chapter 1, Downloading and Installing Nginx.

  • Nginx refuses to start and outputs a message similar to [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use). This error signifies that another application is utilizing the network port 80. This could either mean that another web server such as Apache is already running on the machine, or that you don't have the proper permissions to open a server socket on this port. This can happen if you are running Nginx from an underprivileged system account.

  • Nginx refuses to start and outputs a message similar to [emerg] 3629#0: open() "/path/to/logs/access.log" failed (2: No such file or directory). In this case, one of the files that Nginx tries to open, such as logfiles, cannot be accessed. This could be caused by invalid access permissions or by an invalid directory path (for example, when specifying log files to be stored in a directory that does not exist on the system).
