尝试使用RSA密钥连接到EC2，获取：RSA1标识符不正确...权限被拒绝（公钥）

我在Amazon EC2上创建了一个Ubuntu 12.04实例 .

我已经下载了PEM文件，并且能够SSH进入实例，没问题 .

现在，我想在远程实例上为顾问等创建一些帐户 . 他们应该能够使用RSA密钥进入框中 . 在EC2机器上，我在〜/ home /中设置了几个帐户，并将它们分配给组管理员 . 我也给自己一个类似的帐户（MyTestAccount）进行测试 . 这就是我做的：

我使用key-gen在我的本地机器上的.ssh目录中创建公钥和私钥（〜/ .ssh）：

drwx------  2 peter peter 1024 Sep 14 10:23 .ssh

里面的文件：

-rw-------  1 peter peter 1675 Sep 14 10:23 id_rsa
-rw-------  1 peter peter  394 Sep 14 10:23 id_rsa.pub
-rw-------  1 peter peter  444 Sep 14 00:05 known_hosts

然后，我将id_rsa.pub文件发送到远程EC2实例，并将其附加到远程实例中的.ssh / authorized_keys文件中 . 我的远程.ssh目录的权限：

drwx------ 2 ubuntu ubuntu 4096 Sep 16 16:13 .ssh

和我的authorized_keys文件：

-rw-------  1 peter ubuntu  1179 Sep 14 00:05 authorized_keys

接下来，我注销了我的远程实例，并尝试使用新密钥SSH到远程控制台 . 当我发出以下命令时：

peter@ubuntu:~/.ssh$ ssh -vvv MyTestAccount@ec2-XX-XXX-XX-XXX.compute-1.amazonaws.com

我得到以下内容 . 我的私钥看起来有问题吗？有什么建议？谢谢 .
