我曾使用密钥运行 SSH，但由于某种原因它停止了，我不知道为什么。我尝试通过复制我的公钥进行重新配置，我尝试确保它在客户端中加载，我甚至对远程计算机上的 SSH 配置进行了一些调整。我有 ssh -v，但我不确定问题是什么。这是我的输出（带有一些掩码）

答案1
检查/var/log/auth.log或/var/log/authlog
就我而言，
Authentication refused: bad ownership or modes for directory /home/[USER]
然后我就跑了
chmod go-w ~/
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
现在它起作用了
答案2
你试过吗ssh-copy-id？首先执行这个命令：
ssh-copy-id user@server-ip
它会要求你输入密码。然后执行常规 SSH 命令：
ssh user@server-ip
