无法ssh到AWS EC2:身份文件无法访问

Question

我无法ssh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,我已将目录chmod为755,文件为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,但无法弄清楚为什么......

以下是使用-v的ssh命令的输出,如果有任何用处:

Answer 1

您需要身份文件才能登录该框.使用命令:

ssh -i (identity_file) username@hostname"

这对我有用.只写文件名(没有任何斜杠),不像Amazon EC2教程要求你输入:

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

将身份文件放在主页上的.ssh(隐藏)文件夹后,它对我有用.要在家中查看隐藏文件夹,请使用ctrl+h

Answer 2

我有类似的问题,发现命令中有隐藏的字符,粘贴到纯文本编辑器并复制回来帮助了我.

Answer 3

我也遇到了同样的问题。将身份文件存储在我的~/.ssh目录中并在工作cd ~/.ssh前运行ssh -i (identity_file) username@hostname。我仅在尝试从目录外部运行 ssh 命令时遇到此问题~/.ssh。希望这有帮助

Answer 4

对于你的情况只是

只需执行以下命令即可更改权限

sudo chmod 400 /Users/Skeniver/Keepass/skeniver.pem

然后执行将您连接到 EC2 的命令

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

Answer 5

您需要身份文件才能登录盒子。使用命令

ssh -i (identity_file) username@hostname
