Question

我有一个ec2实例，我想将文件上传到其中。我是这样做的：我从AWS管理控制台找到了公共DNS。然后我运行了scp命令并得到了它。

    scp  -v  helloworld.java ec2-user@ec2-204-236-198-218.compute-1.amazonaws.com:/home
Executing: program /usr/bin/ssh host ec2-204-236-198-218.compute-1.amazonaws.com, user ec2-user, command scp -v -t -- /home

为什么会这样？

Answer 1

您使用的IP地址是一个内部网络地址，只能从EC2可用区内部到达。

您需要使用外部地址来访问实例。您可以使用ec2-describe-instances找到此信息。地址可能类似于ec2.x-x-x-x.blah.amazonaws.com。

此外，虽然您似乎已经在命令行中使用过，但您可能已经允许通过EC2防火墙访问端口22到您的实例。

Answer 2

Caleb是对的。我必须向亚马逊提供一些证件。语法如下： scp -i YOUR_KEY_PAIR FILE_WANT_TO_UPLOAD ec2-user@ec2.x-x-x-x.blah.amazonaws.com:/home/ec2-user 你无法上传到主目录（我猜是因为你使用的是ec2用户名）。

ec2.x-x-x-x.blah.amazonaws.com

是Caleb提到的外部地址。我在原始问题中所做的是从ifconfig命令获取内部地址。再次抱歉弄乱了这个问题。
