Question

我可以使用以下命令ssh到我的linux实例：

ssh -i dj_mongo.pem -v ec2-user@xxx.compute-1.amazonaws.com

但是每当我尝试将文件从本地计算机复制到服务器时，我都会收到以下错误：

 scp -i dj_mongo.pem ck.pem  root@xxx.compute-1.amazonaws.com:/
Please login as the ec2-user user rather than root user.

 scp -i dj_mongo.pem ck.pem  ec2-user@xxx.compute-1.amazonaws.com:/
Permission denied (publickey).
lost connection

dj_mongo-pem和ck.pem都有权限600。

终端输出复制如下：

我该如何处理？请帮忙。

EDITED 现在我不能再ssh了。我使用与昨天相同的密钥。

Answer 1

在典型的详细scp输出中

debug1: Trying private key: dj_mongo.pem
debug1: read PEM private key done: type RSA
debug1: Authentication succeeded (publickey).
Authenticated to your.server.com ([i.p.v.4]:22).

在您的输出中，在读取私有PEM密钥后，它正在跳过它。

很少有明显的事情 -

是否使用与dj_mongo.pem相对应的密钥启动服务器？
您是否正在连接同一台服务器？

Answer 2

我无法找出问题的原因。我最后通过创建新的Linux实例，并附加了我的旧实例的EBS来停止响应它。

Answer 3

我可能错了，但许多版本的linux通过root用户阻止SSH / SCP访问。特别是如果您正在使用Amazon AMI，他们会设置一个名为ec2-user的root用户，您应该已经将pem密钥上传到该用户，因此您应该以此用户身份登录。

无法scp到AWS
