动静分离
动静分离，就是将JSP、Servlet等动态资源交由Tomcat或其他Web服务器处理，将CSS、js、image等静态资源交由Nginx或其他Http服务器处理，充分发挥各自的优势，减轻其他服务器的压力，搭建更为高效的系统架构。
Nginx动静分析的实现¶
下面要搭建Nginx，环境中有三台Nginx主机；一台用于完成负载均衡，两台Nginx用于存放前面项目中的静态资源。另外，还包含前面的两台Tomcat主机。
复制并配置一台Nginx服务器¶
将原来安装有Nginx的主机作为母机，克隆一台Nginx主机，用于存放静态资源：css、js、image。
存放静态资源¶
复制并配置一台Nginx服务器¶
重复上面，复制的那台Nginx操作！！
修改原始那台nginx配置文件(负载均衡，重要！！！)¶
设置静态资源的负载均衡代理，两台nginx的ip分别为：192.168.31.212、192.168.31.213
