这个模块不包含在 Nginx 源码中，安装方法：

1. 首先下载模块源码：https://github.com/agentzh/echo-nginx-module/tags
2. 解压到某个路径，假设为 /path/to/echo-nginx-module
3. 使用下面命令编译并安装 Nginx

$ wget 'http://sysoev.ru/nginx/nginx-1.0.11.tar.gz' $ tar -xzvf nginx-1.0.11. tar .gz $ cd nginx-1.0.11/   # Here we assume you would install you nginx under /opt/nginx/. $ . /configure --prefix= /opt/nginx \ --add-module= /path/to/echo-nginx-module   $ make -j2 $ make install

试试看吧，该模块是国人 @章亦春 开发的。
