一小时前我正在使用我的EC2实例，我使用scp将我的网页上传到我的服务器，一切都很好。我用exit命令关闭了连接，现在我正尝试使用与以前相同的命令登录，我得到了以下信息：Amazon web services ssh连接>；权限被拒绝（公钥）。Ubuntu 12.04 EC2,amazon-web-services,ssh,amazon-ec2,key,rsa,Amazon Web Services,Ssh,Amazon Ec2,Key,Rsa,一小时前我正在使用我的EC2实例，我使用scp将我的网页上传到我的服务器，一切都很好。我用exit命令关闭了连接，现在我正尝试使用与以前相同的命令登录，我得到了以下信息： $ ssh -v -i /cygdrive/c/tsearch.pem ubuntu@tsearch.com.mx OpenSSH_6.1p1, OpenSSL 1.0.1c 10 May 2012 debug1: Connecting to tsearch.com.mx [54.201.232.244] port 22. d

我在网上搜索过，找到了不同的答案，但没有一个有效（我不想删除我的亚马逊实例）。有什么想法吗？最坏的情况是恢复实例中的数据。您可以从实例创建AMI，而无需重新启动。然后使用刚才创建的AMI重新启动另一个实例。稍后，您可以更改DNS（或弹性IP）以指向新实例
您是否更改了实例中~/.ssh/authorized_密钥中的任何内容。或者您在Windows/Cygwin计算机上更改了私钥上的任何内容吗？没有，任何内容。我刚刚发出了一个scp命令，然后所有的命令都被更改了……您在哪里
scp~/.ssh
