1) 五台主机,时间同步,关闭防火墙和selinux
2) 各主机角色
1] 客户端:
192.168.110.27 仅主机(vmnet1) 网关:192.168.110.34
2] ROUTE服务器:
192.168.110.34 仅主机(vmnet1) 网关:无
192.168.136.34 仅主机(vmnet6) 网关:无
3] RS服务器:
192.168.136.36 仅主机(vmnet6) 网关:192.168.136.34
192.168.136.37 仅主机(vmnet6) 网关:192.168.136.34
4] VS服务器:
192.168.136.35 仅主机(vmnet6) 网关:192.168.136.34
3) VIP地址:10.0.0.100
4) 清空ipvsadm规则和相应的IP地址。

1]开启路由功能
echo 1 >/proc/sys/net/ipv4/ip_forward
2]绑定与VIP相同网段的IP:10.0.0.200
ifconfig eth1:1 10.0.0.200/24
?
运行:sh lvs_dr_vs.sh start
脚本如下:
#!/bin/bash

rpm -q ipvsadm &> /dev/null || yum -y install ipvsadm &> /dev/null
