Linux 通过公钥登录ssh密钥

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和授权的_密钥

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，它可以工作，不需要密码，而是以root用户身份登录

但当我尝试

ssh localhost

时，它仍然在询问密码

在此过程中生成的日志包括：-

您能提供创建
授权密钥的绝对路径吗？根用户的主文件夹是什么？Stackoverflow用于帮助检查您的密钥被拒绝的原因。也检查您的密钥被拒绝的原因。还要检查“代码”>授权的密钥KE/<代码>文件的权限，以确保它是正确的。授权的密钥的绝对路径是“代码> /home /cWei/.ssh／AuthixEdEdKEY < /COD>根用户的主页是<代码> /root 
。所有配置文件都在`
/etc/ssh/
下，我发现当我以
sudo/usr/sbin/sshd
的方式启动sshd时，它会工作，当我以
sudo/etc/init.d/sshd start
的方式启动sshd时，它会失败。我如何配置本地.ssh目录？通过将sshd_配置复制到.ssh？假设您有本地用户
chenwei
，以及
chenwei
的主目录是
/home/chenwei
，那么您应该将客户端的公钥（无需密码即可进行ssh登录）放入
/home/chenwei/.ssh/authorized_keys
文件中。您不需要复制sshd_配置文件。
