Chapter 1: What is Nginx?
Before we dive into the details of Nginx, let’s first understand what it is and how it works.
Nginx is a lightweight, open-source web server software that was first released in 2004 by Igor Sysoev. It’s designed to handle high traffic websites efficiently and is known for its speed, reliability, and security. Nginx is widely used by some of the world’s largest websites, including Netflix, Airbnb, and Dropbox, to name a few.
Unlike traditional web servers, Nginx operates in an event-driven, asynchronous architecture, which means it can handle multiple requests simultaneously without the need for separate threads or processes. This makes it highly efficient and capable of serving a large number of requests quickly and reliably.
If you’re looking for a web server that can handle high traffic loads and deliver unparalleled performance, Nginx is an excellent choice.
Chapter 2: Setting Up Nginx
Now that you have a basic understanding of Nginx let’s move on to setting it up. We’ll cover the different installation methods and settings required to get you up and running with Nginx.
The installation process of Nginx is simple and straightforward. You can install it using the package manager, compile it from source code, or use pre-built binaries available on the official website. Depending on your operating system, there might be some variations in the installation process, but the fundamental steps remain the same.
Once you install Nginx, the next step is to configure it to suit your needs. Nginx configuration files are written in plain text and are located in the /etc/nginx directory. You can edit these files using a text editor like Vi or Nano.
There are various Nginx configuration settings that you can tweak to optimize your website’s performance, such as caching, gzip compression, SSL certificate installation, and more. We’ll cover each of these settings in detail in the following chapters.
