我正在使用2個vagrant Centos7實例安裝keepalived進行虛擬IP故障轉移，但有問題（我在生產中遇到同樣的問題）。當主控主機重新啓動時，Keepalived虛擬IP將不會被傳回
基本上，我有兩個運行keepalived的實例。下面是這些2個服務器的配置keepalived.conf：
服務器1的配置：
global_defs {
notification_email {
[email protected]
}
notification_email_from server1.dev.vagrant.net
smtp_server localhost
smtp_connect_timeout 30
}
vrrp_instance VI_enp0s8 {
state MASTER
interface enp0s8
virtual_router_id 51
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.65.110
192.168.65.111
}
}
Server2的配置：
global_defs {
notification_email {
[email protected]
}
notification_email_from server2.dev.vagrant.net
smtp_server localhost
smtp_connect_timeout 30
}
vrrp_instance VI_enp0s8 {
state BACKUP
interface enp0s8
virtual_router_id 51
priority 99
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.65.110
192.168.65.111
}
}
基本上，如果我停止KEEPALIVED使用：sudo的服務KEEPALIVED停在Server1 ;那麼虛擬ipaddresses被成功傳送到server2。當我開始使用「sudo service keepalived start」重新啓動服務器1時，IP地址被轉回。當我在server1上執行「sudo reboot」時，所有內容也都正常工作。但是，如果我使用以下命令關閉然後重新啓動server1：sudo shutdown -h now（或vagrant halt server1）然後流浪server1，則虛擬IP將不會被分配給任一服務器。 （ip addr show enp0s8）。
以下是/ var/log/messages的日誌。在我看來，出於某種原因，虛擬IP已被添加，但隨後被刪除。

如果我登錄到server1，然後手動重新啓動keepalived，那麼事情開始正常工作。
任何人請讓我知道，如果我的配置有什麼問題嗎？
此外，有幾次我無法正常使用sudo服務keepalived stop停止服務;發生這種情況時，虛擬IP不會分配給任何服務器。
感謝。
