..权限被拒绝

我正在尝试通过添加我的本地主机Cassandra节点（用于testing）来设置OpsCenter。我用于SSH的login凭证具有sudo / root权限，但我得到的错误：

scp：/ tmp / tmpXInRfq：权限被拒绝

我可以理解，SCP协议（这在OpsCenter中显然使用）不能像执行“su”命令那样做。但是我错了什么？

在这里输入图像说明

我错了什么？

提前致谢！

亲切的问候，

OpsCenter使用OpsCenter机器上的临时文件来促进ssh。因此，我认为运行OpsCenter的用户没有权限在以下位置创buildtmp文件： /tmp/tmpXInRfq在运行OpsCenter的计算机上，而不是在login凭据中没有sudo权限的问题。您可以确认运行OpsCenter的用户是否可以触摸该位置的文件？

谢谢。
