使用scp命令跨主机拷贝文件时出现Permission denied, please try again(publickey,password)错误，错误如下

root@hj-0219:~/.ssh# scp authorized_keys root@192.168.160.131:/home/
root@192.168.160.131's password: 
Permission denied, please try again.
root@192.168.160.131's password: 
Permission denied, please try again.
root@192.168.160.131's password: 
Permission denied (publickey,password).
lost connection

解决办法，修改/etc/ssh/sshd_config

# Authentication:
LoginGraceTime 120
PermitRootLogin yes  #修改这一行为yes
StrictModes yes

然后重启服务：

systemctl restart ssh.service

就可以复制了。
