外网ip:192.168.1.203(网络模式桥接)
vip:192.168.1.250/32(网络模式eht0)
# echo 1 > /proc/sys/net/ipv4/ip_forward
2、realserver1服务器
主机名:rs1
系统环境:CentOS release 6.5 (Final)
外网ip:192.168.1.201(网络模式桥接)
安装nginx:默认页面访问是web1
3、realserver2服务器和keepalived备用服务器在同一台机器
主机名:rs2
系统环境:CentOS release 6.5 (Final)
外网ip:192.168.1.202(网络模式桥接)
安装nginx:默认页面访问是web2
