[英]Amazon EC2 instance “Permission denied (publickey)”
All time I used this command to get access to my server via SSH 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
Today I tried the same command and got this error message 今天,我尝试了相同的命令,并收到此错误消息

I did not modify my KeyPair.pem
file ("Date modified" = 24-Sep-15) 我没有修改我的
KeyPair.pem
文件(“修改日期” = 15年9月24日)
A very important thing. 一个非常重要的事情。 At last successfully authorized time I executed the next command on the server:
在最后成功的授权时间,我在服务器上执行了下一条命令:
home> chmod -R 777 ubuntu/
Is it possible, that above command ruined my access rights to the server? 上面的命令是否有可能破坏了我对服务器的访问权限?
home> chmod -R 777 ubuntu/ 主页> chmod -R 777 ubuntu /
is the culprit. 是罪魁祸首。 Your /home/ubuntu/.ssh directory has to be 700 and /home/ubuntu/.ssh/authorized_keys has to be 600 .
/home/ubuntu/.ssh目录必须为700 ,/ home / ubuntu / .ssh / authorized_keys必须为600 。 Since they are 777 now, you are out of luck.
由于它们现在是777 ,因此您不走运。 Bur there are ways to restore it.
