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 的权限都是 600。

终端的输出复制如下：

我该如何继续呢？请帮忙。

已编辑现在我不能 ssh 了。我正在使用与昨天相同的密钥。

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 PEM 私钥后，它正在跳过它。

一些明显的事情 -

  1. 服务器是否使用与 dj_mongo.pem 对应的相同密钥启动？
  2. 你连接到同一台服务器吗？

我无法找出问题的原因。最后我创建了新的 Linux 实例，并附加了停止响应它的旧实例的 EBS。

我可能是错的，但是许多版本的 linux 通过 root 用户阻止了 SSH/SCP 访问。特别是如果您使用的是 Amazon AMI，他们会设置一个称为 ec2-user 的根用户，您应该已经将您的 pem 密钥上传到该用户，因此您应该以该用户身份登录。
