修改以下红色字体：
! Configuration File for keepalived

}
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 90
