我已生成 ssh 密钥，我已取消注释公钥身份验证，并在 /etc/ssh/sshd_config 文件中将其设置为 yes。有人发现我的配置中遗漏或不理解的内容了吗？输入密码让我很难过。._。

# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the

先感谢您！！

Jakuje 提醒了我关于 selinux 的事情。我从未遇到过与 ssh 密钥相关的 selinux 问题，但总有第一次！我的 ~/.ssh/* selinux 上下文是 unconfined_u:object_r:unlabeled_t:s0，而它们应该是 unconfined_u:object_r:user_home_t:s0。更改上下文类型后，我能够使用 ssh-copy-id 并直接 ssh 进入！
谢谢你！！
