我正在使用 2 个 vagrant Centos7 实例为虚拟 IP 故障转移安装 keepalived，但遇到了问题（我在生产中遇到了同样的问题）。

基本上，我有 2 个运行 keepalived 的实例。以下是这 2 台服务器的配置 keepalived.conf：

Server1的配置：

global_defs {
   notification_email {
      ABC@gmail.com
   }
   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 {
      ABC@gmail.com
   }
   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 service keepalived stop on server1; 然后虚拟IP地址成功传输到server2。当我使用“sudo service keepalived start”在 server1 上启动 keepalived 时，IP 地址将被传回。当我在 server1 上执行“sudo reboot”时，一切都正常工作。

但是，如果我关闭然后重新启动 server1 使用：sudo shutdown -h now（或 vagrant halt server1）然后 vagrant up server1，那么虚拟 IP 将不会分配给任一服务器。（ip 地址显示 enp0s8）。

下面是 /var/log/messages 的日志。在我看来，由于某种原因，虚拟 IP 已被添加，但随后被删除。

如果我登录到 server1，然后手动重新启动 keepalived，那么事情就会开始正常工作。

如果我的配置有什么问题，有人可以告诉我吗？

此外，有几次我无法使用 sudo service keepalived stop 正确停止服务；发生这种情况时，虚拟 IP 不会分配给任一服务器。

谢谢。

根据日志，在网络接口 enp0s8 启动并准备好之前，keepalived 已经启动。如果你想让keepalived跟踪接口，你应该在vrrp_instance中添加这样的东西

track_interface {
    enp0s8
}
