Question

我一直使用此命令通过SSH访问我的服务器

ssh -i "KeyPair.pem" ubuntu@52.26.255.0

今天我尝试了同样的命令并收到了此错误消息

Permission denied (publickey)

使用-v选项我收到了此消息

我没有修改我的KeyPair.pem文件（＆＃34;修改日期＆＃34; = 24-Sep-15）

非常重要。在最后成功授权的时间，我在服务器上执行了下一个命令：

home> chmod -R 777 ubuntu/

上述命令是否可能破坏了我对服务器的访问权限？

Answer 1

主＆GT; chmod -R 777 ubuntu /

是罪魁祸首。您的/home/ubuntu/.ssh目录必须 700 且/home/ubuntu/.ssh/authorized_keys必须 600 。由于他们现在 777 ，你运气不好。 Bur有办法恢复它。搜索StackOverflow。
