我正在AWS上设置DSE 5。我有一个单独的OpsCenter 6.0.0节点。我有三个群集节点，a，b和c。
每个服务器，OpsCenter加3个节点，都是安装了Oracle JDK1.8.0_92的Ubuntu 14.04服务器。
在OpsCenter节点上，我安装并启动了OpsCenter Ok。
我创建了一个集群Ok，但是当我回到OpsCenter来管理该集群时，代理没有进行通信。我试图自动安装代理，但失败了。
我进入/ usr / share / opscenter，运行bin / setup.py，并将/ usr / share / opccenter / ssl文件夹和文件复制到/ var / lib / datastax-agent / ssl /中的节点/ p>
在我的群集节点上，在agent.log中，我得到以下内容：

显然，setup.py没有正确构建/ var / lib / datastax-agent / ssl / agentKeyStore。
我撤回了所有这些步骤并且没有错误。
有什么想法吗？
