mesosphere-high-availability cluster未能选举领导人，但日志显示没有错误，似乎无法强制选举领导人

我有一个6机集群。这些机器是：

HOST        MEM (GB) CPU
mesos-primary-1     8       2
mesos-primary-2     8       2
mesos-primary-3     8       2
mesos-worker-1      1       1
mesos-worker-2      1       1
mesos-worker-3      1       1

我的仲裁大小设置为2。
主机的id分别为：1、2和3。在webui中，我访问了 mesos-primary-1 , mesos-primary-2 以及 mesos-primary-3 在端口5050上，我没有收到来自任何一个ip的重定向。
缺乏重定向使我相信，似乎每台机器都认为自己拥有自己的法定人数或其他东西，这就是为什么他们未能看到对方并选出领导人。
访问港口 8080 在任何一台机器上都会出现一个错误，因为没有选出的领导人，但它确实解决了问题。 $ cat /etc/mesos-master/quorum 在每台主机上输出2。
我也停止/重新启动了一切。在主节点上：

$ sudo service mesos-master stop\
sudo service marathon stop\
sudo service zookeeper stop\
sudo service mesos-master start\
sudo service marathon start\
sudo service zookeeper start

在每台从机上

$ sudo service mesos-slave stop\
sudo service mesos-slave start

仍然没有一个奴隶被发现，也没有一个领导人被选举出来。
我的日志在所有3个IP上都是干净的（我得到了每个IP，因为没有重定向），您可以在这里查看每个IP：

在我看来，要么你的机器无法互相访问，要么你的一些或所有机器的端口被阻塞在正确的端口上。确保：
答。2181（zookeeper）、2888和3888（分别为从属连接和主选择）以及5050（mesos）/8080（如果您使用的是marathon）上的端口被解锁，用于桌面/笔记本电脑的ui。奴隶只需要2888我相信可以从主人那里得到。
b。您可以先ping一台机器上的所有其他主机，即使用主机1和ping主机2和3。
c。在担心从机之前，先尝试正确调试组成集群的主机。
您在这里似乎有一组很好的配置和正确的仲裁设置，一旦确定计算机可以相互连接，就可以调查其他潜在问题。告诉我们进展如何！
