Question

我正在克隆ghost open blog cms，有一个选项可以通过数字海洋运行vps。选择此方法将创建液滴。下一步是以 root@XXXXX 身份登录

这样做时，我得到了可怕的权限被拒绝（公钥）。我重新创建了 ssh 密钥并在数字海洋中进行了更新，但这并没有解决问题。

运行 ssh -v root@xxxx 命令时，输出如下：

知道如何处理这个问题吗？

Answer 1

我已经能够解决这个问题并将解释如何解决。

我的问题是即使在 Droplet 中重置密码后，我的密码也没有被接受。

可以在此处找到“控制台中不接受密码”信息https://docs.digitalocean.com/products/droplets/resources/troubleshooting-ssh/authentication/

我按照引导进入此处链接的恢复过程：https://docs.digitalocean.com/products/droplets/resources/recovery-iso/#boot-into-the-recovery-iso

关闭电源或停止液滴
选择从恢复 ISO 启动
再次打开水滴
点击控制台

在这个阶段，我看到了一个选项列表。

挂载您的磁盘映像 [未挂载]
检查文件系统
重置 Droplet 根密码
配置键盘
尝试“chroot”进入已安装的系统
交互式外壳 [/bin/bash] 选择 (1-6) 并按 Enter 继续。

我选择了选项 1，然后是 3，然后是 6。
在此之后，我关闭了 Droplet 并选择了从硬盘启动。
访问控制台，我能够登录并输入接受的密码，ghost 安装开始并成功完成。

我希望这对遇到相同问题的人有所帮助。
