scp（安全副本）到ec2实例，无需密码

本文翻译自：scp (secure copy) to ec2 instance without password

I have an EC2 instance running (FreeBSD 9 AMI ami-8cce3fe5), and I can ssh into it using my amazon-created key file without password prompt, no problem.

我有一个正在运行的EC2实例（FreeBSD 9 AMI ami-8cce3fe5），我可以使用我的亚马逊创建的密钥文件将其ssh进入，而无需输入密码提示，没有问题。

However, when I want to copy a file to the instance using scp I am asked to enter a password:

但是，当我想使用scp将文件复制到实例时，要求输入密码：

scp somefile.txt -i mykey.pem [email protected]:/

Password:
           

Any ideas why this is happening/how it can be prevented?

My

hadoopec2cluster.pem

file was the only one in the directory on my local mac, couldn't scp it to aws using

scp -i hadoopec2cluster.pem hadoopec2cluster.pem [email protected]:~

.

我的

hadoopec2cluster.pem

文件是本地Mac上目录中的唯一文件，无法使用

scp -i hadoopec2cluster.pem hadoopec2cluster.pem [email protected]:~

其scp到aws

scp -i hadoopec2cluster.pem hadoopec2cluster.pem [email protected]:~

。

Copied hadoopec2cluster.pem to hadoopec2cluster_2.pem and then

scp -i hadoopec2cluster.pem hadoopec2cluster_2.pem [email protected]:~

.

将hadoopec2cluster.pem复制到hadoopec2cluster_2.pem，然后将

scp -i hadoopec2cluster.pem hadoopec2cluster_2.pem [email protected]:~

复制到hadoopec2cluster_2.pem

scp -i hadoopec2cluster.pem hadoopec2cluster_2.pem [email protected]:~

。

Voila!

瞧！

I was hung up on this because I was specifying my public key file in

我之所以挂在这里，是因为我在中指定了我的公钥文件

scp -i [private key file path]
           

When I caught that mistake and changed it to the private key path instead, I was all set.

当我发现该错误并将其更改为私钥路径时，一切都准备就绪。

lets assume that your pem file and somefile.txt you want to send is in Downloads folder

假设您要发送的pem文件和somefile.txt位于“下载”文件夹中

scp -i ~/Downloads/mykey.pem ~/Downloads/somefile.txt [email protected]:~/
           

let me know if it doesn't work

让我知道是否无效
