Apache zookeeper 梅索斯大师未当选为领袖

我正在一台物理机器的集群上部署Mesos/Marathon/zookeeper：这是一种可行的配置吗？
（我有两台机器，但从第一台开始）

当启动Mesos时，我在页面上得到以下结果：“目前没有主控器处于领先地位，此主控器不是领导者…”

我把法定人数设为1，这是一个可能的值吗？我尝试了0，但mesos甚至没有启动

仲裁应至少大于或等于您拥有的zookeeper服务器的一半OK，因此我有1台zookeeper服务器，仲裁应大于等于0.5因为仲裁不能浮动，我将其设置为1。您可以检查mesos serever日志，查看它是否正在运行并连接到zookeeper。如果您遵循以下配置，请在后检查中显示所有配置：
