环境标准：一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一一
内核：2.6.32-642.el6.x86_64
系统：CentOS> ip：
web01:10.0.0.8nginx解析手机端均做了nginx的负载均衡但是只均衡一台机器可以后续往里填
web02:10.0.0.200nginx解析电脑端均做了nginx的负载均衡但是只均衡一台机器可以后续往里填
lb01:10.0.0.201nginx负载均衡lb01主负载均衡
lb02:10.0.0.31nginx负载均衡lb02备的负载均衡
vip:10.0.0.5(虚拟)keepalive虚拟路由冗余保证负载均衡存在解决单点问题
