无法与 IP 地址建立 ssh 连接，但可以与 git 建立

Question

我正在尝试将网站从我的 github 存储库部署到 Digital Ocean，但是我无法 ssh 到我的 Digital Ocean Droplet。 （对此非常陌生 - 请原谅任何明显的问题）我收到此错误：

alexschutz@Alexs-MBP ~ % ssh -v root@[MY IPaddress]

我也收到此错误：

alexschutz@Alexs-MBP ~ % ssh-copy-id root@[MY IPADDRESS]
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/Users/alexschutz/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@[MY IPADDRESS]: Permission denied (publickey).

不太确定冲突的公钥是否是问题所在。

几天前我能够通过 ssh 进入它，但我不确定从那以后我做了什么来破坏事情。

此时，最好使用密码登录您的 Droplet 并弄清楚发生了什么。当前已禁用此功能（ssh 不会提示您输入密码）。要启用它，请参阅如何使用恢复控制台恢复对 Droplet 的访问。

然后您可以使用

ssh-copy-id

和密码来获取 Droplet 上的 SSH 密钥。然后，您应该查看 Droplet 上的

~/.ssh/authorized_keys

以找出问题所在。
