设置 OpsCenter 时出现：scp /tmp/.. 权限被拒绝

我正在尝试通过添加本地主机 Cassandra 节点来设置 OpsCenter（用于测试）。我用于 SSH 的登录凭据具有 sudo/root 权限，但我还是收到错误：

scp：/tmp/tmpXInRfq：权限被拒绝

我可以理解 SCP 协议（​​显然在 OpsCenter 中使用）无法执行诸如“su”命令之类的操作。但我做错了什么？

我做错什么了？

提前致谢！

OpsCenter 使用 OpsCenter 机器本身上的临时文件来方便 ssh。因此，我认为问题不在于登录凭据没有 sudo 权限，而在于运行 OpsCenter 的用户可能没有权限在以下位置创建临时文件：在运行 /tmp/tmpXInRfq OpsCenter 的机器上。您能否确认运行 OpsCenter 的用户是否可以接触该位置的文件？

谢谢。
