我无法通过 ssh 连接到我的 EC2 服务器并收到错误:

ssh -i /Users/Skeniver/Keepass/skeniver.pem ubuntu@xx.xxx.xx.xxx

Identity file /Users/Skeniver/Keepass/skeniver.pem not accessible: No such file or directory

该文件肯定在目录中，并且我已将目录更改为 755，将文件更改为 600:

drwxr-xr-x  14 Skeniver  staff    476 28 Nov  2012 Keepass
-rw-------  1 Skeniver  staff    1696  5 Oct  2012 skeniverkey.pem

我很确定这是一个权限问题，但不知道为什么......

这是使用 -v 的 ssh 命令的输出，以防有任何用处:

Answer 1

您需要身份文件才能登录 Box。使用命令:

ssh -i (identity_file) username@hostname"

这对我有用。仅写入文件名(不带任何斜杠)，这与要求您输入的 Amazon EC2 教程不同:

ssh -i /path/key_pair.pem ec2-user@public_dns_name

将身份文件放入主目录的 .ssh(隐藏)文件夹后，它对我有用。要查看主页上的隐藏文件夹，请使用 ctrl+h
