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 release 6.8 (Final)

ip：

web01:10.0.0.8 nginx 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

web02:10.0.0.200 nginx 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

lb01:10.0.0.201 nginx 负载均衡lb01 主负载均衡

lb02:10.0.0.31 nginx 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
