Question

我尝试使用OpsCenter 5.2.4创建新群集但我收到此错误：

Error: Fingerprint Detection failed: sequence item 0: expected string, NoneType found

在OpsCenter /var/log/opscenter/opscenterd.log的日志中我收到此错误：

有什么想法吗？

OpsCenter配置开发人员。这告诉你失败的操作：

2016-10-09 10:02:06+0000 [] ERROR: /usr/bin/ssh-keyscan had some issues:
    stdout=
    stderr=        getaddrinfo None: Name or service not known

这可能与网络有关。你可以对有问题的主机运行ssh-keyscan吗？或者你能不能对它进行ssh-keys扫描？我猜不到，你需要搞乱网络防火墙，iptables和/或你的路由，直到你能够从OpsCenter服务器ssh到目标主机。

另请注意，OpsCenter 6.0.x中的配置功能比5.2.x中的配置功能提前了几年。我强烈建议你升级。
