我有一个6机器群。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
我的法定人数大小设为2。
主机的id分别为：1,2和3。
在网络用户界面中，我访问了端口5050上的mesos-primary-1，mesos-primary-2和mesos-primary-3的每个IP，并且我没有收到任何来自任何一个IP的另一个IP的重定向它们。
缺乏重定向导致我相信每台机器都认为它拥有自己的法定人数或其他东西，这就是为什么他们没有看到对方并选出领导者。
任何计算机上的访问端口8080都会出现错误，因为没有当选的领导者，但它确实解决了。
$ cat /etc/mesos-master/quorum
在每台主机上输出2。
我也停止/重启了一切。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
在每台奴隶机上
$ sudo service mesos-slave stop\
sudo service mesos-slave start
仍然没有一个奴隶被发现，也没有领导人当选。
我的日志在所有3个IP上都是干净的（由于没有重定向，我得到了每个IP），你可以在这里查看每个IP：

答案 0 :(得分：1)
对我而言，您的计算机相互之间无法访问，或者在正确端口上的部分或全部计算机上端口被阻止。确保：
A。在2181（zookeeper），2888和3888（分别是奴隶加入和大师选举）和5050（mesos）/ 8080（如果您正在使用马拉松）中取消阻止端口您的桌面/笔记本电脑的用户界面。奴隶只需2888我相信可以从大师那里获得。
B。您可以先从一台机器ping所有其他主机，即使用主机1和ping主机2和3.
C。在担心奴隶之前，首先尝试正确调试形成群集的主人。
您似乎在这里有一套好的配置和正确的仲裁设置，一旦您确定机器可以相互连接，您就可以调查其他潜在问题。让我们知道它是怎么回事！
