将文件上传到 Fedora 中的 ec2 实例
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 scp 命令并得到了这个 .
scp -v helloworld.java [email protected]:/home

为什么会出现这种情况？
I have a ec2 instance and I want to upload file into it. I did it this way:
I found the public DNS from the AWS management console.
Then I ran the scp command and got this .
scp -v helloworld.java [email protected]:/home
Executing: program /usr/bin/ssh host ec2-204-236-198-218.compute-1.amazonaws.com, user ec2-user, command scp -v -t -- /home

您使用的 IP 地址是内部网络地址，只能从 EC2 可用区域内部访问。
您需要使用外部地址来访问实例。您可以使用
ec2-describe-instances找到它。该地址可能类似于 ec2.xxxx.blah.amazonaws.com。此外，尽管您似乎已经进入命令行，您可能已经完成了此操作，但您可能需要允许通过 EC2 防火墙访问您的实例的端口 22。
The ip address you are using is an internal network address that can only be reached from inside the EC2 availability zone.
You need to use the external address to reach the instance. You can find this using
ec2-describe-instances. The address will likely be something like ec2.x-x-x-x.blah.amazonaws.com.Additionally, although since you seem to already be in on the command line you might have already done this, you might need to allow access to port 22 through the EC2 firewall to your instance.
迦勒是对的。我必须向亚马逊提供一些凭据。语法如下：
scp -i YOUR_KEY_PAIR FILE_WANT_TO_UPLOAD [电子邮件受保护]:/home/ ec2-用户您无法上传到主目录（我猜是因为您使用的是 ec2 用户名）。
就是 Caleb 提到的外部地址。我在最初的问题中所做的是从 ifconfig 命令获取内部地址。再次抱歉搞砸了这个问题。
Caleb is right. i have to offer some credentials to amazon . the Syntax is like:
scp -i YOUR_KEY_PAIR FILE_WANT_TO_UPLOAD [email protected]:/home/ec2-useryou can't upload to the home directory(i guess because you are using the ec2-user name).
is what Caleb mentioned as the external address. what i did in my original questions is i got the internal address from the
ifconfigcommand. sorry again for messing up the question.
