不能使用SSH连接EC2实例 [英] Can't SSH Into EC2 Instance

问题描述

所以我纺我的实例从网页，下载的密钥对安装了它，一切约一天伟大的工作。然后我重新启动我的电脑，我不能够通过SSH进入它了。我试着重新下载一个密钥，并重新安装，但我不断收到权限被拒绝（公钥）错误。

So I spun my instance up from the web, downloaded a keypair installed it and everything worked great for about a day. Then I rebooted my computer, and I'm not able to SSH into it anymore. I tried redownloading a keypair and reinstalling it but I keep getting the Permission denied (publickey) error.

这是冗长的输出（我使用-i /路径/到/密钥对的选择，以及没有运气尝试过）：

This is the verbose output (I've tried using the -i /path/to/keypair option as well with no luck):

我也试着重新启动实例。任何人有什么我能试试吗？非常感谢！

I've also tried rebooting the instance. Anyone have anything else I can try? Thanks so much!

推荐答案

解决。我从我的计算机中删除我的AWS密钥对。不这样做。它会锁定你了永远的实例。

Solved. I had deleted my AWS keypair from my computer. Don't do this. It will lock you out of your instance forever.
