在LVS服务器中修改配置文件

vi /etc/keepalived/keepalived.conf

修改以下红色字体：

! Configuration File for keepalived

global_defs {

lvs_id 5

}

vrrp_sync_group VGM_2 {

group {

VI_2

}

notify_master /root/startdr.sh

notify_backup /root/stopdr.sh

}

vrrp_instance VI_2 {

state MASTER    #备份服务器上将MASTER改为BACKUP

interface eth2

lvs_sync_daemon_inteface eth2

virtual_router_id 55

priority 100   #备份服务器上priority

advert_int 5

authentication {

auth_type PASS

auth_pass 1111

}

virtual_ipaddress {

}

}
