我已经使用 设置了公钥身份验证ssh，但发生的情况是，当我第一次登录时，它仍然要求输入密码，任何后续登录（同时保持第一次登录处于活动状态）都不会要求输入密码。我不知道任何设置会产生这种行为。有人知道为什么我第一次被提示输入密码吗？
该密码肯定不是访问密钥的密码，因为我ssh从服务器收到登录消息，并要求我输入user@remote密码。
编辑：输出ssh -vvv user@remote：

答案1
这可能是由于您的主目录（以及密钥）在登录期间无法访问所致。这可能是由于您的主目录在登录后从网络驱动器（在共享系统上）安装或您的主目录被加密（通常是工作站的安装）造成的。
解决这个问题很复杂，但我会看看一些讨论。解决方案是将AuthorizedKeysFile密钥移至其他可访问的位置或我们的密钥全局存储 ( /etc/security/authorized_keys)，或某种 SSO 管理系统（IPA、LDAP），该系统将从目录服务器获取密钥（是的，可以是本地的） ）。取决于您对目标系统的控制程度。
也许最好的解决方案是将密钥存储在其他位置，更改以下值sshd_config：
AuthorizedKeysFile /etc/ssh/%u/authorized_keys
