ssh密钥通过公钥登录

标签: linux ssh

我正在使用公钥访问设置ssh,我想我已经正确配置了sshd_config并生成了id_rsa.pub和authorized_keys。

ssh-kengen -t rsa
cd .ssh
cat id_rsa.pub >> authorized_keys

我还设置了这些文件的权限

chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

当我尝试sudo ssh localhost时,它可以正常工作,不会询问密码,但会以root用户身份登录。

但是当我尝试ssh localhost时,它仍然要求输入密码。

在此期间生成的日志是: -

Ssh公钥访问是基于用户的。可以为root用户完成配置。需要通过配置本地用户本地.ssh目录为本地用户完成。
