# Practical development ginx Module **[简体中文](http://git.oschina.net/wujunze/nginx_module_echo/blob/master/README_zh.md)** ## nginx_module_echo echo string ## Nginx Version Nginx1.0.10 https://github.com/nginx/nginx/releases/tag/release-1.0.10  ## The development environment configuration ```shell OS : CentOS Linux release 7.2.1511 (Core) ```   ## Install a clean compile Nginx 1. Download a Nginx10.10 and unpack it  2. Install the GCC and the lib Nginx need   3. ./configure --prefix=/usr/local/nginx && make && make install    4. Nginx run   ## Definition module configuration structure ```C typedef struct { ngx_str_t ed; //该结构体定义在这里 https://github.com/nginx/nginx/blob/master/src/core/ngx_string.h } ngx_http_echo_loc_conf_t; ```  ## Define Nginx instruction and parameter conversion function  ## definition module Context 1. Define the type of ngx_http_module_t structure variables  2. Initialize a configuration structure  3. Will the father block configuration information incorporated into this structure Implement the configuration of inheritance  ## Write the Handler really work part of the module  ## Combination Nginx module  ## Finishing module code According to the Nginx official specification  ## Write the config file ```shell ngx_addon_name=ngx_http_echo_module HTTP_MODULES="$HTTP_MODULES ngx_http_echo_module" NGX_ADDON_SRCS="$NGX_ADDON_SRCS $ngx_addon_dir/src/ngx_http_echo_module.c" ``` ## make && make install ```shell ./configure --prefix=/usr/local/nginx/ --add-module=/root/ngx_dev && make && make install ``` ## Successful installation  ## Modify the Nginx configuration file test Module  ## Nginx echo Module The successful running  # If the repo help you welcome star fork Thanks! > ## reference > 1. http://wiki.nginx.org/Configuration > 2. http://tengine.taobao.org/book/ > 3. **http://blog.codinglabs.org/articles/intro-of-nginx-module-development.html** > 4. https://www.nginx.com/resources/wiki/modules/
