问题描述

我想将朋友的公共SSH密钥添加到正在运行的AWS EC2实例.如何在Mac上执行此操作?

I would like to add my friend's public SSH key to a running AWS EC2 instance. How do I go about doing this on a Mac?

推荐答案

非常简单:

1. SSH进入您的EC2实例
2. 复制朋友的公共SSH密钥
3. 将其添加到~/.ssh/authorized_keys

示例:

ssh ec2-user@your-ec2-instance # optional: -i ~/.ssh/YourPrivateKey.pem
echo "PASTE YOUR KEY HERE" >> authorized_keys

确保您朋友的钥匙上有描述性注释非常有用，这样，当您查看authorized_keys时，您不仅会看到钥匙和"user-1234 @ mac-local"或其他东西，评论-您的朋友"会更好.

It'd be useful to ensure your friend's key has a descriptive comment on it, so that when you view authorized_keys you don't just see the key and "user-1234@mac-local" or something as the comment - "YourFriend" would be better.
