亚马逊 EC2 实例 "Permission denied (publickey)"

Amazon EC2 instance "Permission denied (publickey)"

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

今天我尝试了相同的命令并收到了这条错误消息

Permission denied (publickey)

使用 -v 选项我收到了这条消息

我没有修改我的 KeyPair.pem 文件("Date modified" = 24-Sep-15)

一件很重要的事情 最后成功授权的时候我在服务器上执行了下一条命令:

home> chmod -R 777 ubuntu/

有没有可能,上面的命令破坏了我对服务器的访问权限?

主页> chmod -R 777 ubuntu/

是罪魁祸首。您的 /home/ubuntu/.ssh 目录必须是 700 并且 /home/ubuntu/.ssh/authorized_keys 必须是 600.因为他们现在是 777,你真倒霉。但是有办法恢复它。搜索 Whosebug。
