无法访问Amazon EC2实例 [英] Can't access to amazon ec2 instance

问题描述

使用SSH终端无法访问到Amazon EC2实例：

I can't access to amazon ec2 instance using ssh terminal:

ssh -i new.pem ubuntu@<public-ip>

报告说，连接被关闭＆LT;公共IP>

It says connection closed by <public ip>

和FileZilla中停止工作，我收到此错误：

and FileZilla stopped working and I am getting this error:

错误：服务器意外关闭网络连接
  错误：无法连接到服务器

Error: Server unexpectedly closed network connection
Error: Could not connect to server

这之后，我改变了服务器的的/ etc 文件夹的权限775更新所有发生的事情的的php.ini 的文件。

This all happened after I changed the server's /etc folder's permissions to 775 to update the php.ini file.

发生了什么事？

推荐答案

听起来像你的情况可能是继权限更改大清洗。

Sounds like your instance may be hosed following the permission changes.

从来没有这种事发生在我，所以没有亲自使用的回收技术。

Never had this happen to me so not personally used the recovery technique.
