NGINX is a powerful web server that has gained popularity due to its high performance, scalability, and reliability. It’s used by some of the world’s most popular websites, including Netflix, Dropbox, and WordPress.com. In this article, we’ll take you through the process of building NGINX from scratch.

What is NGINX?

NGINX (pronounced “engine-x”) is a free, open-source web server software that can also be used as a reverse proxy, load balancer, and HTTP cache. It was created by Igor Sysoev in 2002 to solve the C10k problem, which refers to the difficulty of handling more than 10,000 concurrent connections.

Why Build NGINX?

Building NGINX from scratch allows you to customize it according to your specific needs. You can choose the features and modules that are relevant to your use case, which results in a smaller binary size and improved performance. Additionally, building NGINX gives you more control over the build process, allowing you to optimize it for your specific hardware.

Use Cases

NGINX is commonly used in the following scenarios:

• Web serving: NGINX can serve static web content, such as images, videos, and HTML files.
• Reverse proxying: NGINX can act as a reverse proxy server, forwarding requests from clients to upstream servers.
• Load balancing: NGINX can distribute incoming traffic across multiple backend servers.
• API gateway: NGINX can serve as an API gateway, handling incoming API requests and routing them to the appropriate services.

Step-by-Step Guide to Building NGINX

Step 1: Install Prerequisites

Before building NGINX, you need to install some prerequisites on your system. These include:

• GCC: The GNU Compiler Collection is required for compiling NGINX.
• PCRE: The Perl Compatible Regular Expressions library is used by NGINX for regular expression matching.
• Zlib: The zlib compression library is used by NGINX for compressing and decompressing data.

To install these prerequisites on Ubuntu or Debian, run the following command:

sudo apt-get update && sudo apt-get install build-essential libpcre3 libpcre3-dev zlib1g-dev

Step 2: Download NGINX Source Code

Next, download the NGINX source code from the official website. You can do this by running the following command:

wget http://nginx.org/download/nginx-1.20.0.tar.gz && tar -xvf nginx-1.20.0.tar.gz

Step 3: Configure NGINX

After extracting the source code, navigate into the extracted directory and run the configure script to configure NGINX:

./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_v2_module --with-http_realip_module

This command configures NGINX with some common modules. You can customize this command by adding or removing modules as per your requirements.

Step 4: Build NGINX

After configuring NGINX, run the following command to build it:

make && sudo make install

This command compiles and installs NGINX on your system.

Conclusion

Building NGINX from scratch allows you to customize it according to your specific needs. By following this step-by-step guide, you can build a highly optimized version of NGINX that meets your performance requirements. Whether you’re using NGINX as a web server, reverse proxy, or load balancer, building it from scratch gives you more control over the configuration and features.
