我一直在Win7上通过SSH访问我的EC2实例。我不想在Ubuntu 12.04上的另一台PC上使用ssh，得到“Permission denied（publickey）”。错误。我一直在寻找这个问题，并尝试以下方法：ssh - 亚马逊EC2上的权限被拒绝（publickey）
- 删除现有密钥并在EC2仪表板上创建/下载新密钥。
- 将新密钥放置在我的〜/ .ssh文件夹中。
改变了密钥的访问权限与此命令（也试过400）：
搭配chmod 600的〜/ .ssh/leno.pem
改变了的.ssh文件夹的与此有关的访问权限命令（也试过700）：
搭配chmod 755的〜/ .ssh
试图这样做，以及：
附加的ssh 〜/ .ssh/leno.pem
没有运气。当我尝试运行以下命令：
ssh -vvv -i ~/.ssh/leno.pem [email protected]
我得到这个消息：

如何通过SSH访问我的EC2 insance？我究竟做错了什么？
谢谢。我能够使用原始密钥进行连接。 – boomslang
那么如何安装它？ –
@KinnardHockenhull每个用户在主目录的'.ssh'文件夹中都有自己的'authorized_keys'文件。文件的格式非常简单，每行只有一个公钥。如果用户没有它，您可以创建它，但它必须具有只允许用户访问它的权限。 – datasage
