DC / OS安装挂起在飞行前的50％

我想testing一下DC / OS的社区编辑，我不能让它在飞行前的50％上进展：在这里输入图像说明

我遵循这里列出的gui指令，并开始以详细模式进行安装。这是最后一个非“GET预检”输出：

我也下载了包含以下内容的gui日志：

引导机器是我的电脑，主机/代理是在我的电脑上运行的CentOS 7 KVM机器。我也确保SSH密钥可以在没有密码的情况下工作。我需要做什么才能使安装进度？

最好使用高级安装程序，它不依赖引导节点上的SSH密钥，这可能会导致此类问题。

安装程序挂在install prereqs阶段。这个阶段可能需要很长时间，取决于从正在运行的机器到更大的互联网的networking连接以及主机性能。

此阶段安装必备软件包（在CentOS上使用yum），安装和configurationDocker，以及确保主机处于DC / OS最低可安装状态。

你退出之前跑了多久？

顺便说一句，当安装阶段开始时，进度条计为该主机的50％，当主机完成安装时达到100％。由于安装程序运行并行SSH会话（30是默认设置，但可以在configurationyaml中使用parallelism参数进行设置），它将同时执行两个主机，而且两者都不完整，所以显示已完成50％。
