Question

我有一个Aws EC2实例已经运行了几个月没有任何问题。

今天，当我想使用ssh访问它时：

ssh -i＆＃34; DRUID_PROD_NEW.pem＆＃34; ec2-user@eX.X.X.x.compute-1.amazonaws.com

我收到了

权限被拒绝（publickey）。

昨天运作良好，但现在我无法连接。过去几个月我没有对服务器进行任何更改。

我在2月份遇到了完全相同的问题。我不得不做一个新的实例，并复制一切。如果这是一个常态，那将是一个完全失业的亚马逊。

我感谢任何帮助。

我发现了什么问题。

几周前，我将ec2-user目录更改为group readable。它显然使机器无法进入。我完全忘记了这一点，今天当我需要访问机器时，我收到了臭名昭着的错误。

因此，将ec2-user主目录的权限更改回755解决了这个问题。

感谢您花时间尝试帮助我摆脱这种情况。
