Nginx+Tomcat负载均衡群集

    nginx处理静态    tomcat处理动态    合并为动静分离（前后端分离）

Tomcat重要目录

    bin：存放启动和关闭Tomcat脚本    conf：存放Tomcat不同的配置文件    doc：存放Tomcat文档    lib/japser/common：存放Tomcat运行需要的库文件    logs：存放Tomcat执行时的LOG文件    src：存放Tomcat的源代码    webapps：Tomcat的主要Web发布目录

实验前置知识点:

Nginx静态处理优势

    1.Nginx处理静态页面的效率远高于Tomcat的处理能力    2.如果Tomcat的请求量为1000次，则Nginx的请求量为6000次    3.Tomcat每秒的吞吐量为0 6M，Nginx的每秒吞吐量为3.6M    4.Nginx处理静态资源的能力是Tomcat处理的6倍，优势可见一斑

动静分离原理：服务端接收来自客户端的请求中，既有静态资源也有动态资源

环境准备：

    nginx：192.168.18.147----CentOS 7-1    Tomcat 1：192.168.18.128----CentOS 7-2    Tomcat 2：129.168.18.148----CentOS 7-3    客户端：192.168.18.129----Win 7
