解决方案

我在使用 vagrant 时遇到了同样的问题.所以我试图从我的 Mac 上 ssh 到一个 vagrant box (CentOS 7)

通过修改 /etc/ssh/sshd_config PasswordAuthentication yes 解决了这个问题，然后使用 sudo systemctl restart sshd 重新启动了服务p>

希望这会有所帮助.

解决方案

I had the same issue while using vagrant. So from my Mac I was trying to ssh to a vagrant box (CentOS 7)

Solved it by amending the /etc/ssh/sshd_config PasswordAuthentication yes then re-started the service using sudo systemctl restart sshd

Hope this helps.
