所选用户秘钥未在远程主机上注册

最近配置key登录centos的时候报这个错误，公钥私钥都是对的

第一步查看系统错误日志

tail -f /var/log/secure

结果如下

Dec 26 04:48:45 localhost sshd[82282]: Authentication refused: bad ownership or modes for directory /home/leisiyuan
Dec 26 04:48:49 localhost sshd[82282]: error: Received disconnect from 118.116.94.114: 0:  [preauth]
Dec 26 04:49:10 localhost sshd[82329]: Received disconnect from 223.111.139.247: 11:  [preauth]

可以看到错误上面的第一行就是目录权限不对

直接设置目录权限

chmod 755 /home/leisiyuan/

再登录就没有报错，成功登录了
