在控制台中输入命令：1）开启防火墙：【service iptables start】，【chkconfig iptables on】2）清空路由规则：【iptables -F】3）在控制台中输入命令：【iptables -A OUTPUT -d {VIP} -p tcp -m tcp --dport {VPORT} -j DNAT --to-destination {RIP:RPORT}】，其中{VIP}、{VPORT}为虚拟IP和端口， {RIP:RPORT}为真实服务的IP和端口4）保存路由配置：【service iptables save】1）从“控制面板”中选择“添加硬件”，选中“是，硬件已连接好”，如果是Window7或Window2008则需要打开设备管理器，然后“添加过时硬件”。2）下一步，选中“添加新的硬件设备”3）下一步，选中“安装我手动从列表选择的硬件”4）下一步，选中“网络适配器”5）下一步，从microsoft中选择loopback适配器6）下一步，直至完成最后在网络邻居的网络连接中对刚建立的loopback适配器进行配置7）在real server上为虚拟网卡设置IP为LVS的VIP，子网掩码为：255.255.255.0（或255.255.255.255）。其他不需要设置。8）禁用网卡后重新启用即可。
把下面命令保存到一个BAT脚本中，按右键以管理员权限执行。其中“本地连接 3”是物理网卡的名称，“loopback”是虚拟网卡的名称。【netsh interface ipv4 set interface "loopback" weakhostreceive=enablednetsh interface ipv4 set interface "loopback" weakhostsend=enablednetsh interface ipv4 set interface "本地连接 3" weakhostreceive=enabledpause】
