Nginx 初探：Nginx+IIS

Nginx 是一个高性能的 Web 和反向代理服务器, 它具有有很多非常优越的特性:

作为 Web 服务器：相比 Apache，Nginx 使用更少的资源，支持更多的并发连接，体现更高的效率，这点使 Nginx 尤其受到虚拟主机提供商的欢迎。能够支持高达 50,000 个并发连接数的响应，感谢 Nginx 为我们选择了 epoll and kqueue 作为开发模型.

作为负载均衡服务器：Nginx 既可以在内部直接支持 Rails 和 PHP，也可以支持作为 HTTP代理服务器 对外进行服务。Nginx 用 C 编写, 不论是系统资源开销还是 CPU 使用效率都比 Perlbal 要好的多。

作为邮件代理服务器: Nginx 同时也是一个非常优秀的邮件代理服务器（最早开发这个产品的目的之一也是作为邮件代理服务器），Last.fm 描述了成功并且美妙的使用经验。

以上内容来自Nginx 中文文档，废话少说，直接上code：

安装Nginx 之后，主要是配置nginx.conf ，参考http://nginx.org/en/docs/ 有完整的module 介绍

配置：
两台webserver 搭载IIS 2013：
本机作为Nginx 做负载均衡服务器

备注：

1.upstream 与proxy_pass 对应虚拟负载均衡主机集群名称一致pisa.com
2.负载均衡可以通过配置权重或者ip_hash 的方式进行,需要注意共享session 的问题参考

最终结果，如果web 网站设置成windows 集成认证，Nginx 官方文档介绍支持NTLM ，但是研究发现免费版不支持, 这一点需要注意，免费版支持form 认证或者匿名认证

附上nginx 命令

打开cmd到nginx 安装目录
1.启动 start nginx
2.修改配置文件后重启 nginx -s reload
3.退出 nginx -s quit 或者 nginx -s stop
4.打开日志 nginx -s reopen
5.查看版本 nginx -v
