vi /etc/ssh/sshd_config

查找RSAAuthentication、StrictModes、PubkeyAuthentication、AuthorizedKeysFile把所在行修改为:

RSAAuthentication yes
StrictModes no
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys

重启SSH服务

systemctl restart sshd.service

然后用xshell或者linux自己的keygen生成私钥和公钥,把公钥拷贝到/root/.ssh/authorized_keys即可
