keepalived1端操作：

在单主模型配置基础上添加一个新的虚拟路由配置：

vim /etc/keepalived/keepalived.conf

重启keepalived服务

systemctl restart keepalived

开启httpd服务

echo keepalived1 > /var/www/html/index.html

systemctl restart httpd

keepalived2端操作：

在单主模型配置基础上也添加一个对应的新虚拟路由配置：

vim /etc/keepalived/keepalived.conf

重启keepalived服务

systemctl restart keepalived

开启httpd服务

echo keepalived2 > /var/www/html/index.html

systemctl restart httpd

此时keepalived1与keepalived2分别拥有一个虚拟IP地址：

keepalived1：

keepalived2：

客户端测试：

模拟keepalived2下线

systemctl stop keepalived

此时查看keepalived1的IP地址：发现两个虚拟IP都来到keepalived1端

客户端再次发起测试：
