尝试部署我的第一个Web应用程序，并且难以通过SSH进入AWS。当我进入：
ssh -v -i ec2-myportfolio.pem root@ec2-23-23-165-24.compute-1.amazonaws.com
我获得了Permission denied（公钥）。我在堆栈上看了几个其他的响应 this和this，但都没有解决问题。以下是我得到的错误。在此先感谢您的帮助。

我认为你的问题就在这一行：
Warning: Identity file ec2-myportfolio.pem not accessible: No such file or directory.
您是否在ssh命令中使用了正确的路径引用和文件名？
