【问题描述】：

我正在尝试使用我的公共 ssh 密钥在数字海洋上创建一个水滴，水滴启动正常，但我无法通过 ssh 连接它。它提示我输入密码。

我通过数字海洋去了 ubuntu 服务器控制台，查看了 ~/.ssh/authorized_keys，我看到了我的公钥。

这是 ssh {server_ip} -v 命令的输出：

【问题讨论】：

您能否编辑您的问题以包含远程系统上 .ssh 目录的“ls -la”输出？

您正在尝试以 root 身份登录远程系统？在服务器的 sshd_config 文件中，“PermitRootLogin”设置为什么？

【解决方案1】：

您正在以{myuser} 身份进行身份验证，并且您向我们展示了root 的主文件夹。目前尚不清楚您要实现什么，但有两种可能：

您想以{myuser} 身份进行身份验证，然后您需要将authorized_keys 复制到相应的主目录(/home/{myuser}/.ssh/) 并修复 ovnership。
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）！请注意，不推荐设置。

你说得对，我确实知道我在做什么。我应该使用 ssh root@{servier_ip}
