[英]permission denied public key while copying folder/file from local machine to AWS ec2 instance with scp command in putty
我有一个运行ubuntu的EC2实例,并且我使用腻子连接到了该实例。 我正在尝试将一些文件上传到此实例,但是一次又一次地获得许可被拒绝的公共密钥错误。 以下是我尝试过但收到相同错误的命令。

我也以root用户身份尝试过。 自6个小时以来,我一直在努力弄清楚,现在真的很沮丧。 我是linux的新手。 请帮我解决这个问题。 提前致谢
在示例终端输出中,您的前两次scp尝试甚至从未尝试进行身份验证。 远程系统仅接受公共密钥身份验证(不接受密码),并且ssh没有任何可用于身份验证的公共密钥。
在您的第三次scp尝试中,有以下内容:
$ scp -r -v -i \Users\Rohan\Desktop\fall2014 courses\research\bucketsort-aws.pem \xampp\htdocs\bucketsorter\index.php ubuntu@ip-172-31-24-22:home/ubuntu/var
Executing: [...]
Warning: Identity file UsersRohanDesktopfall2014 not accessible: No such file or directory.
您告诉它使用没有引号的密钥文件“ \\ Users \\ Rohan \\ Desktop \\ fall2014 course \\ research \\ bucketsort-aws.pem”。 Scp最终寻找了一个名为“ UsersRohanDesktopfall2014”的密钥文件。 它找不到此密钥,因此再次无法认证。
首先,密钥文件的名称包含一个空格,因此必须将其用引号引起来,才能将其视为单个命令行参数。 其次,看起来命令行上的反斜杠已被修饰,因此请尝试使用正斜杠代替:
$ scp -r -v -i "/Users/.../fall2014 courses/research/bucketsort-aws.pem" /xampp/.../index.php ubuntu@ip-172-31-24-22:home/ubuntu/var
这是在Windows上吗? 如果scp仍然抱怨无法找到密钥文件,请添加驱动器说明符:
$ scp -r -v -i "C:/Users/.../fall2014 courses/research/bucketsort-aws.pem" /xampp/.../index.php ubuntu@ip-172-31-24-22:home/ubuntu/var
$ scp -r -v -i \Users\Rohan\Desktop\fall2014 courses\research\bucketsort-aws.pem \xampp\htdocs\bucketsorter\index.php ubuntu@ip-172-31-24-22:home/ubuntu/var
为什么在上述命令中使用反斜杠 ? 你到底在做什么
另外,如果要将文件从本地Windows工作站复制到远程EC2 Linux框中,请使用FileZilla,WinSCP或BitWise之类的文件。
PuTTy无法传输文件。
此外, ubuntu@ip-172-31-24-22:home/ubuntu/var
应该是ubuntu@ip-172-31-24-22:/home/ubuntu/var
(注意/ home
