从图像构建后的ssh到azure-vm

Question

我已经从现有的ubuntu创建了一个映像。在此之后，我使用蔚蓝文档创建了一些基于该映像的vms。我在CLI中用于创建VM的命令是

az vm create --resource-group <groupname> --name <vmname>
--image <imagename> --admin-username <adminname>
--ssh-key-value ~/.ssh/id_rsa.pub

创建的VM很好，但我不能通过ssh连接到它们。当我

ssh -v <adminname>@IP

我得到了

我是新来的这个洞天青-unix-东西，所以我只能假设它与创建vms的命令中的'ssh-key-value‘有关.我必须对vms做什么？哦，vms的操作系统是Ubuntu-16.04.

Answer 1

根据您的错误日志，您在~/.ssh中没有私钥。

请使用ssh-keygen创建一个新的密钥，并使用Azure再次创建新的VM。

如果你知道你的私人位置。您可以使用ssh -i <path/id_rsa> user@ip对VM进行ssh。

创建VM时使用--generate-ssh-keys替换--ssh-key-value ~/.ssh/id_rsa.pub的另一个解决方案。
