Overview of this book

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 book is a detailed guide to setting up Nginx in ways that correspond to actual production situations: as a standalone server, as a reverse proxy, interacting with applications via FastCGI, and more. In addition, this complete direct reference will be indispensable at all stages of the configuration and maintenance processes. This book mainly targets the most recent version of Nginx (1.13.2) and focuses on all the new additions and improvements, such as support for HTTP/2, improved dynamic modules, security enhancements, and support for multiple SSL certificates. 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 so that it does exactly what you need quickly and securely. For more experienced administrators, this book provides different approaches 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.

Installing via package managers

The quickest, and easiest, way to install Nginx is to simply use your OS-provided version. Most of the time, these are kept fairly updated; however, for some Linux distributions focusing on stability, you may only have older versions of Nginx available. Sometimes, your Linux distribution may provide multiple versions of Nginx with different compile flags.

In general, before embarking on a more complex journey, we should check if we can use the easy solution. For a Debian-based operating system, we first find the Nginx compiles available then get the info for the one we want:

apt-cache search nginx
apt-cache show PACKAGE_NAME
apt-get install PACKAGE_NAME

For Red Hat Linux-based operating systems, we need to enable the EPEL repo first and then do the same:

yum install epel-release
yum search nginx

yum install PACKAGE_NAME

If the version provided is current enough, then you're ready to configure Nginx in the next chapter.

If the version provided by your distribution is too old, then Nginx provides packages for RHEL/CentOS distributions as well as Debian/Ubuntu distributions.

Nginx provided packages

To set up a yum repository for RHEL/CentOS, create a file named /etc/yum.repos.d/nginx.repo with the following contents:

name=nginx repo

Replace OS with rhel or centos, depending on the distribution used, and OSRELEASE with 6 or 7, for versions 6.x or 7.x, respectively. Afterwards, Nginx can now be installed with yum:

yum install nginx

For Debian-based distributions, we need to first use their signing key to authenticate the package signatures. Download the following file first from

Then run the following command:

sudo apt-key add nginx_signing.key

With the key added, we can now add the Nginx repository to our sources.list found in /etc/apt/sources.list. For Debian, we add the following lines:

deb codename nginx
deb-src codename nginx

Where codename is either jessie or stretch depending on your version of Debian. For Ubuntu, we use the following dependencies:

deb codename nginx
deb-src codename nginx

Where codename is one of trusty, xenial, or zesty depending on your version of Ubuntu. Finally, we can install Nginx with the apt-get command option:

apt-get update
apt-get install nginx
