2.这个时候，你已经有了一对密钥，需要开始设定服务器的配置，启用密钥认证登录，同时为了系统安全着想，关闭密码认证的方式！

# vim /etc/ssh/sshd_config

修改下面几处：

PubkeyAuthentication  yes  #启用PublicKey认证。
    AuthorizedKeysFile       .ssh/authorized_keys  #PublicKey文件路径。
    PasswordAuthentication  no  #不适用密码认证登录。

[root@192 .ssh]# vim /root/.ssh/authorized_keys
    将公钥内容复制到次文本中

![在这里插入图片描述][20200722204544805.png]

3.接着，修改该文件的权限，否则可能会遇到问题！

[root@192 .ssh]# chmod 600 authorized_keys

4.重启ssh服务

[root@192 .ssh]# systemctl restart sshd

5.至此，登录测试吧！你会发现输入完用户，密码一栏是灰色的！

用户，密码一栏是灰色的！

登录成功，配置完成！
