**nginx是一款轻量级WEB服务器，也是一款反向代理服务器**

### 1.nginx能干什么 ###

*      1.可以支持Rails和PHP程序 
 *      2.可以作为HTTP反向代理服务器 
 *      3.作为负载均衡服务器
 *      4.作为邮件代理服务器
 *      5.帮助实现前端动静分离  (目前实现的动静分离 )

### 2.nginx特点 ###

**高稳定；高性能；资源占用少；功能丰富；模块化结构；支持热部署**

# 二.Nginx能做什么有什么优势 #

**客户端假设通过HTTP协议访问A网站中的应用服务器，那么网站管理者可在服务器加一个Nginx(也就是所谓的反向代理)，让客户端线先请求Nginx，随后Nginx去请求应用服务器，然后将结果返回给客户端。那么可能会有小伙伴疑惑既然可以直接访问HTTP，那为何要多此一举，去先访问代理呢，这么做就什么好处呢，优势如下。**

**优势1-支持负载均衡**

**当一个网站访问量特别大的时候，网站的各种速度都会越来越慢，一台服务器肯定是不够用了。这个时候就需要将应用部署在多台服务器上，将请求平摊给多台服务器来处理。这样的好处是，万一某一台服务器GG了，但只要还有其他的服务器正常运行，就不会影响使用。这个时候就可以通过Nginx反向代理来实现负载均衡。**
