无法ssh到AWS EC2:身份文件无法访问

问题描述 投票:35回答:8

我无法ssh到我的EC2服务器并收到错误:

ssh -i /Users/Skeniver/Keepass/skeniver.pem [email protected]

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:

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

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。

我遇到了同样的问题。将标识文件存储在我的~/.ssh目录中并在cd ~/.ssh工作之前运行ssh -i (identity_file) username@hostname。尝试从~/.ssh目录外部运行ssh命令时,我只遇到了这个问题。希望这会有所帮助

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 [email protected]

我有同样的问题,我发现文件路径的问题。右键单击你的key_pair.pem(相同的文件)去属性并复制,现在你的评论就像

ssh -i /path/skeniver.pem user@your_public_ip

例如在我的情况下命令就像

ssh -i /home/anil/.ssh/webKey.pem [email protected]

尝试使用

ssh -i Users/Skeniver/Keepass/skeniver.pem [email protected]

代替

chmod 600 ~/.ssh/public_key_file为我解决了
