AWS公钥被拒绝问题

Question

我读了这篇文章：

AWS ssh 访问“权限被拒绝（公钥）”问题

那里的信息是相关的，但不能帮助我解决我的问题。我过去能够使用 ec2-user 使用以下命令登录 AWS 上的 Linux 实例：

ssh -i key.pem ec2-user@[address].compute-1.amazonaws.com 从我的 MacBook 终端

过去几周后，我现在收到此错误：

“权限被拒绝（公钥）。”

我

从 MacBook 终端尝试了 ssh -v -i key.pem ec2-user@[address].compute-1.amazonaws.com

并得到以下输出：

OpenSSH_5.2p1, OpenSSL 0.9.8r 8 Feb 2011

对发生的情况有任何建议吗？如何解决这个问题？

我之前在该实例上创建了另一个用户帐户。我可以用它登录，并 sudo 进入根目录。我只是无法再使用 ec2-user 登录。

谢谢！

您可能必须以 root 身份登录。如果使用 bitnami 映像，请以“bitnami”身份登录，

例如 ssh -v -i key.pem bitnami@[address].compute-1.amazonaws.com
