生成秘钥
首先生成秘钥，秘钥短语可以不生成。
ssh-keygen -t rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
然后修改文件权限：
chmod go-w $HOME $HOME/.ssh
chmod 600 $HOME/.ssh/authorized_keys
chown `whoami` $HOME/.ssh/authorized_keys
修改sshd配置
vi /etc/ssh/sshd_config
RSAAuthentication yes
StrictModes yes
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
然后重启sshd服务:
service sshd restart
#centos 7:
systemctl restart sshd.service
然后就可以使用秘钥登陆了，把私钥(id_rsa)下载到本机登陆。注意权限的问题，另外，使用xshell登录的时候，还是要输用户名噢！（竟然犯了这么蠢的错误，还一直以为是权限的问题）
