AWS：为我的用户添加 SSH 密钥

Question

I just created an instance on AWS EC2. I got the ec2-user's pub/private keys and I'm able to login using my puTTY client from my Windows machine.

Now, I want to connect to the same instance with a new user(xxxx). For that:

• First I created a user using 'useradd' on AWS instance
• Generated pub/private keys on my windows machine using puTTYgen
• Copied pub key content to >> /root/.ssh/authorized_keys file.
• Now, I'm trying to connect using puTTY by using the private key

But I'm unable to login, and I'm getting the following error:

Authentication log (see session log for details):
Using username "xxxx".
Server refused our key
No supported authentication methods left to try!

Connection has been unexpectedly closed. Server sent command exit status 0.

Answer 1

我可以通过在 xxxx 用户主目录（ /home/xxxx/.ssh/authorized_keys ）而不是/root/.ssh/authorized_keys下创建一个 authorized_keys 文件来解决这个问题
