如何從源碼編譯帶自定義模塊的Nginx？首先準備好所需的依賴和工具，其次在配置階段通過--add-module參數(shù)添加模塊路徑，最后進行編譯安裝。具體步驟如下：1. 安裝GCC、PCRE、zlib、OpenSSL及make等必要依賴；2. 下載并解壓Nginx源碼；3. 執(zhí)行./configure命令時使用--add-module參數(shù)指定模塊路徑，并根據(jù)需要啟用其他模塊或選項；4. 運行make與sudo make install完成編譯安裝；5. 使用nginx -V命令驗證模塊是否成功添加；6. 修改nginx.conf以啟用新模塊功能；7. 每次升級Nginx或修改模塊時需重新編譯構建。整個過程需要注意模塊路徑的正確性以及保存配置命令以便后續(xù)參考。

Compiling Nginx from source with a custom module gives you more control over its functionality, especially when you want to add features not included in the default build. It’s not overly complicated, but it does require attention to detail and a few specific steps.

Prepare Your Environment

Before diving into compilation, make sure your system has all the necessary tools and libraries installed. Most Linux distributions come with these by default, but it's good to double-check.

Here’s what you’ll typically need:

• GCC compiler
• PCRE library (for rewrite support)
• zlib library (for gzip compression)
• OpenSSL library (if you need HTTPS support)
• Make utility

For Debian/Ubuntu-based systems, run:

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

Once dependencies are installed, download the Nginx source code from the official site:

wget http://nginx.org/download/nginx-1.xx.x.tar.gz
tar -zxvf nginx-1.xx.x.tar.gz
cd nginx-1.xx.x

Add the Custom Module During Configuration

The key step is including your custom module when running the ./configure script. You do this using the --add-module flag followed by the path to your module’s source directory.

Let’s say your module is located in /home/user/nginx-module-example. Then your configure command might look like this:

./configure --add-module=/home/user/nginx-module-example --with-http_ssl_module --with-http_gzip_static_module

You can include other standard modules or options as needed—just make sure the custom module path is correct. If the module requires additional libraries, don’t forget to install them and possibly pass extra flags (like --with-xxx).

Note: Some third-party modules may require you to specify --add-module=../module-name if they're placed outside the Nginx source tree.

Compile and Install

Once configuration completes without errors, run:

make
sudo make install

This compiles Nginx and installs it to /usr/local/nginx by default. If you prefer a different installation path, use the --prefix option during configuration.

To verify that your module was included, run:

/usr/local/nginx/sbin/nginx -V 2>&1 | grep "add-module"

If everything went smoothly, you should see the module path listed in the output.

One thing to watch out for: if you're upgrading Nginx later, you'll need to recompile with the same module options again. So it's helpful to save your full ./configure command somewhere for future reference.

That’s basically it. Once installed, you can start configuring your new module via the Nginx config file (/usr/local/nginx/conf/nginx.conf) and test how it behaves under real conditions. Just remember, every time you change the module or Nginx version, you’ll need to rebuild from scratch.
