AWS SSH从OSX连接不断询问SSH密码的密码

Question

根据本的回答，我创建了一个密钥对，将私钥下载到〜/ .ssh，将权限更改为600，并尝试ssh实例...但有未经授权的埃罗：

如果我更改用户名的Ubuntu，并且它运行良好......得到connecte d ..;

您已将X.509 Certificates与Amazon EC2 Keypairs混淆。 EC2密钥对用于登录到EC2实例。

在EC2控制台中，找到左侧的密钥对部分，生成密钥对，并将私钥保存在本地磁盘上。 OpenSSH默认搜索~/.ssh目录。运行chmod 600 ~/.ssh/<filename>以设置正确的权限。然后，您可以使用该密钥通过SSH访问您的实例。
