如何解决权限被拒绝(公钥)错误

Question

我正在克隆ghost开放博客cms，可以选择通过数字海洋运行vps。选择此方法将创建液滴。下一步是以身份登录root@XXXXX

在这样做的时候，我得到了可怕的拒绝许可(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

我已经解决了这个问题，并将解释如何解决。

我的问题是，即使在液滴中重置了密码，我的密码也没有被接受。

"控制台中不接受密码"；信息可以在这里找到https://docs.digitalocean.com/products/droplets/resources/troubleshooting-ssh/authentication/

我按照引导进入恢复过程链接到这里：https://docs.digitalocean.com/products/droplets/resources/recovery-iso/#boot-进入回收iso

• 关闭电源或停止液滴
• 选择从恢复启动ISO
• 再次打开液滴
• 单击控制台

在这个阶段，我有一个选项列表。

1. 装载磁盘映像[未装载]
2. 检查文件系统
3. 重置Droplet根密码
4. 配置键盘
5. 尝试"chroot"到已安装的系统
6. 交互式Shell[/bin/bash]选择(1-6(并按Enter键继续

• 我选择了选项1，然后是3，然后是6。

• 在这之后，我关闭了液滴并选择从硬盘启动。

• 访问控制台时，我可以登录并输入密码，密码被接受，幽灵安装开始并成功完成。

我希望这能帮助任何遇到同样问题的人。
