vrrp下的lvs
网络拓扑结构https://s1.运维网.com/wyfs02/M01/95/BF/wKiom1kZWa3BHbECAAHqvO4pHQE741.png-wh_500x0-wm_3-wmp_4-s_1494057270.png
操作系统为centos7.3
1.所有主机RS1、RS2、DS1、DS2都开apache服务器，RS1、 RS2都用来测试web服务器的，DS1 、DS2是用来做sorry 服务器的。
2.所有服务器都时间同步
3.在DS上开vrrp

DS1上配置
! Configuration File for keepalived
global_defs {
notification_email {

}
notification_email_fromAlexandre.Cassen@firewall.loc
smtp_server 127.0.0.1
smtp_connect_timeout 30

}
vrrp_instance jin-vrrp {

auth_pass 1111
}
virtual_ipaddress {

DS2上配置

做这个实验的时候要小心花括号。
4.在二个RS服务上写脚本用来做lvs-dr里的VIP

在lo上生成vip地址及路由条目。

5.由于二个DS配完keepalived的vrrp后。只要yum ipvsadm就可以了，至于ipvsadm策略会通过keepalived会自动生成

6.测试结果
