成功连接后无法连接到Mesos浏览器消息

Question

如您所见，我可以通过浏览器连接到地址为http://ec2-35-180-230-169.eu-west-3.compute.amazonaws.com:5050/#/的Mesos

但是2秒钟后，该屏幕弹出，显示“无法连接到ec2-35-180-230-169.eu-west-3.compute.amazonaws.com:5050！”

Safari和Firefox上存在相同的问题。

以下是状态信息：

Answer 1

Mesos UI使用leader_info端点中的state.json来查询领导者。第一个请求转到用户提供的URL，但随后尝试直接命中领导者。在您的示例中，领导者信息是：

"leader_info":{
  "id":"c54f9020-25c2-4890-8072-37e591a2f1d6",
  "pid":"master@172.31.47.43:5050",
  "port":5050,
  "hostname":"paris2x"
},

并且UI尝试连接'//' + leader_info.hostname + ':' + leader_info.port ，因此您的情况将是//paris2x:5050。

要解决此错误，您需要将主机的主机名更改为可访问的主机名或在其前面放置外观。
