macos - 无法从 osx SSH 到 ubuntu 液滴

Question

我正在尝试使用我的公共(public) ssh key 在 digital ocean 上创建一个液滴，液滴启动良好，但我无法对其进行 ssh。它提示我输入密码。

我通过 digital ocean 去了 ubuntu 服务器控制台并查看了 ~/.ssh/authorized_keys 并看到了我的公钥。

这是 ssh {server_ip} -v 命令的输出:

Answer 1

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

您想以 {myuser} 身份进行身份验证然后你需要复制authorized_keys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(PermitRootLogin 中的 sshd_config 选项)!请注意，不推荐设置。
