我正在尝试以主机用户身份进行 SSH。
我已经使用 ssh-keygen 为gitlab主机上的用户创建了 ssh 密钥，并将公钥复制到我的本地id_rsa.pub机器，~/.ssh/authorized_keys同时将私钥复制id_rsa到本地机器。
当我尝试使用以下命令进行 ssh 时：
ssh -v -i id_rsa [email protected]
我收到以下权限被拒绝错误：

不确定如何进一步调试。
答案1
弄清楚了。
public_key 需要存在于生成 ssh-keypair 的用户/home/<user>/.ssh/authorized_keys中<user>
答案2
您必须在执行 .ssh 命令的用户的 .ssh/ 目录中拥有 id_rsa.pub 和 id_rsa。在远程主机上，您必须将 id_rsa.pub 复制为您代表其进行 ssh 的用户主目录中的 .ssh/authorized_keys。
