无法从 osx 连接到 ubuntu droplet

Question

我正在尝试使用我的 public ssh 密钥在数字海洋上创建一个 droplet，droplet 启动正常，但我无法通过 ssh 访问它。它提示我输入密码。

我通过数字海洋进入 ubuntu 服务器控制台并查看了 ~/.ssh/authorized_keys 并且我看到了我的 public 密钥。

这是 ssh {server_ip} -v 命令的输出：

Answer 1

您正在以 {myuser} 的身份进行身份验证，并且向我们展示了 root 的主文件夹。不清楚你要实现什么，但是有两种可能：

您想验证为 {myuser}，然后您需要将 authorized_keys 复制到适当的主目录 (/home/{myuser}/.ssh/) 并修复权限。
您想以 root 身份进行身份验证，然后您应该使用：
```
ssh -v root@{server_ip}
```
但请确保您允许 root 登录（sshd_config 中的 PermitRootLogin 选项）！并注意不推荐设置。
