Question

我正在使用2个流浪汉Centos7实例安装keepalived for virtual IP failover但有问题（我在生产时遇到同样的问题）。

基本上，我有两个运行keepalived的实例。以下是这两台服务器的配置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，如果我停止使用keepalived：sudo service keepalived stop on server1;然后将虚拟ipaddresses成功传输到server2。当我使用“sudo service keepalived start”开始使用“sudo service keepalived start”重新启动keepalived时，会将ip地址转回。当我在server1上执行“sudo reboot”时，一切都正常工作。

但是，如果我关闭然后使用以下命令重新启动server1：sudo shutdown -h now（或vagrant halt server1）然后将server1弄乱，则虚拟IP将不会分配给任一服务器。（ip addr show 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然后手动重启keepalived，那么事情就会开始正常工作。

任何人都可以告诉我配置是否有问题？

另外，有几次我无法使用sudo service keepalived stop正常停止服务;发生这种情况时，虚拟IP不会分配给任何一台服务器。

感谢。

根据日志，keepalived已在网络接口enp0s8启动并准备就绪之前启动。如果您希望keepalived跟踪接口，则应在vrrp_instance

中添加类似的内容

track_interface {
    enp0s8
}

当主机主机再次启动时，不会传回Keepalived虚拟IP
