我一直使用此命令通过 SSH 访问我的服务器
ssh -i "KeyPair.pem" <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="27524552495352671215091511091512120917" rel="noreferrer noopener nofollow">[email protected]</a>
今天我尝试了相同的命令并收到此错误消息
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(“修改日期”= 2015 年 9 月 24 日)
一件非常重要的事情。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/
上面的命令是否可能破坏了我对服务器的访问权限？
最佳答案
主页> chmod -R 777 ubuntu/
是罪魁祸首。您的/home/ubuntu/.ssh 目录必须为 700，而/home/ubuntu/.ssh/authorized_keys 必须为 600。既然他们现在是777，那么你就不走运了。但是有一些方法可以恢复它。搜索 StackOverflow。
