Nginx ("engine x") 是一款高性能的，轻量级的HTTP Web 服务器 和 反向代理服务器及电子邮件 IMAP/POP3/SMTP 代理服务器。
Nginx 是由俄罗斯的程序设计师 Igor Sysoev 所开发，为俄罗斯访问量第二的 Rambler.ru 站点开发的，它已经在该站点运行超过四年多时间了，Igor 将源代码以类BSD许可证的形式发布。
自 Nginx 发布四年来，Nginx 已经因它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名了。Nginx 超越Apache的高性能和稳定性，使得国内使用 Nginx 作为 Web 服务器的网站也越来越多。
目前国内各大门户网站已经部署了Nginx，如新浪、网易、腾讯等；新近发现 Nginx 技术在国内日趋火热，越来越多的网站开始应用部署Nginx。
一、首先去官网下载 nginx1.0.11的Windows版本，官网下载：http://nginx.org/download/nginx-1.0.11.zip
下载到软件包后，解压 nginx-nginx1.0.11.zip 包到你喜欢的根目录，并将目录名改为nginx。
然后，执行下列操作：
cd nginx
start nginx
这样，nginx 服务就启动了。打开任务管理器，查看 nginx.exe 进程，有二个进程会显示，占用系统资源，那是相当的少。然后再打开浏览器，输入 http://127.0.0.1/ 就可以看到nginx的欢迎页面了，非常友好
nginx -s stop // 停止nginx
nginx -s reload // 重新加载配置文件
nginx -s quit // 退出nginx
二、接下来就是配置nginx的conf文件了。下面是我的配置：
#user nobody;worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
