NGINX is a versatile, high-performance web server, often used for reverse proxying, load balancing, and other web-related tasks. One of its strengths is the extensibility provided through modules. While there are many built-in modules, you can also compile your own dynamic modules to extend its functionality.
In this tutorial, we will guide you through the steps needed to compile a dynamic NGINX module. For demonstration purposes, we will use a hypothetical module named
- NGINX source code that matches the version you’re running.
- A C compiler such as gcc.
- Development libraries for NGINX.
- A code editor such as Vim, Emacs, or VSCode.
Step 1: Download NGINX Source Code
First, download the NGINX source code that matches the version you are running. You can find this on the NGINX website.
wget http://nginx.org/download/nginx-1.20.0.tar.gz tar -xzvf nginx-1.20.0.tar.gz cd nginx-1.20.0/
Step 2: Install Dependencies
Next, install the required dependencies:
sudo apt-get update sudo apt-get install build-essential libpcre3 libpcre3-dev zlib1g zlib1g-dev openssl libssl-dev
Step 3: Prepare Your Module Code
Prepare your module’s
.c source file. For this example, the file would be named
ngx_http_my_module.c. Place this file in a separate directory.
Step 4: Configure and Compile NGINX
From within the NGINX source directory, configure NGINX with your module:
./configure --add-dynamic-module=/path/to/your/module make make install
If everything went well, you should see a
ngx_http_my_module.so file in the
Step 5: Load the Dynamic Module
Finally, to use your module, you’ll need to load it within your NGINX configuration file. Add the following line in your
sudo nginx -s reload
Congratulations! You have successfully compiled a dynamic NGINX module. This basic tutorial should give you a starting point from which you can build more complex modules to enhance your NGINX setup. Keep coding!
