ssh conection＆gt;权限被拒绝（publickey）。 Ubuntu 12.04 EC2

Question

我在1小时前使用我的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，现在我尝试使用与以前相同的命令登录，我得到了这个：

$ ssh -v -i /cygdrive/c/tsearch.pem ubuntu@tsearch.com.mx

我在网上搜索过，我找到了不同的答案，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？

最糟糕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。然后使用刚刚创建的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。
