EC2 Ubuntu实例 - 未受保护的私钥文件

Question

我刚刚在EC2上创建了一个Ubuntu实例,但当我尝试通过SSH进入机器时,我得到:

UNPROTECTED PRIVATE KEY FILE!  
permissions 0644 for 'xxxxx.pem' are too open.
It is recommended that your private key files are NOT accessible by others.
This private key will be ignored.
bad permissions: ignore key: xxxxx.pem
Permission denied (publickey).

在创建密钥时,您只需输入名称(无需添加密码).

如何在没有出现此警告的情况下SSH进入机器？

Answer 1

私钥必须只能由所有者读取..

不要chmod 400 xxxxx.pem在机器上要从中连接
