LVS/NAT 配置
三台服务器一台作为director, 两台作为real server
Director 有一个外网ip(192.168.31.166) 和一个内网ip(192.168.21.166)
两个real server上只有内网ip(192.168.21.100)和(192.168.21.101) 并且需要把两个real server的内网网关设置为director的内网ip(192.168.21.166)
两个real server 上都安装httpd: yum install -y nginx
Director上安装ipvsadm yum install -y ipvsadm
Direcotr 上 vim/usr/local/sbin/lvs_nat.sh
