Login ansible远程用户作为根用户

我想开始学习ansible，但有一件事我不懂：

flipl@sun ~ % ansible -vvvv -m ping t420
SUDO password:

It is sometimes useful to re-run the command using -vvvv, which prints SSH debug output to help diagnose the issue.

任何帮助都将不胜感激

谢谢，

您是否已将您的公钥添加到远程服务器中的授权文件中？

好的，我解决了它

root# ssh-copy-id flipl@t420

解决了它

我想，我误解了ssh密钥的概念

是的，我这样做了，但有一点很奇怪：“flipl$ssh t420”工作正常，但“root#ssh”flipl@t420'不起作用…可能您的根键与用户flipl不同。检查它们是否不同，您需要将root密钥也添加到远程服务器的授权文件中。正如我提到的，不允许通过ssh以root身份登录，那么为什么我必须添加我的root ssh密钥？？？

root# ssh-copy-id flipl@t420
