用户的SSH密钥授权

场景：有多个用户需要SSH到服务器。我正在下面是用户的SSH密钥授权

创建用户1，用户2在服务器（Ubuntu的14.04服务器）在AWS EC2上运行。
添加每个用户的公钥（id_rsa.pub）到服务器/home/$USER/.ssh/authorized_keys文件

问题是，我只能ssh来ubuntu（默认用户）与用户的私钥。但我不能SSH进入user1用户。

你有错的文件名。这不是

/home/$USER/.ssh/authorize_key

但

/home/$USER/.ssh/authorized_keys

这是我在帖子中的错误，修复了帖子中的文件名。 –

仍然错误。该文件的权限是什么？ – Jakuje

对不起固定文件名，文件权限'700'，尝试'777'，同样'权限被拒绝（publickey）'。错误 –
