我无法登录我的 Amazon ec2 实例。我设置了它，下载了密钥。起初它抱怨因为我的权限设置正确。然后我执行：chmod 400 myKey.pem。当我尝试登录时，我仍然得到： Permission denied (publickey)
接下来我删除了所有密钥并尝试刷新： rm -rf ~/.ssh
我对这个问题的其他回答感到困惑。似乎有 1000 件事可能会出错，我不知道从哪里开始。我使用 -v 选项运行它，它生成了以下输出（见下文）。我不知道该怎么做。
作为初学者，我下一步应该尝试什么？

答案1
好的，我通过反复试验找到了这个问题的答案。
下面是AMAZON告诉我使用的字符串。
ssh -v -i myKey.pem [email protected]
接下来是我首先尝试的
ssh -v -i myKey.pem [email protected]
错误信息提示使用bitnami。
ssh -v -i myKey.pem [email protected]
除了偶然发现这一点之外，我怎么知道用户名是 bitnami？
