使用 ssh 将 git 克隆到 VPS 时出现 Permission denied(publickey) 错误

Question

我已将公钥从本地计算机复制到授权密钥文件中，并复制到 VPS 上我用户的 ssh 目录中。 但是当我执行 git clone 时，我得到了 Permission denied(publickey) 错误

我在运行时得到这个日志

我不确定我还需要做什么。我还使用公钥创建了 authorized_keys2 但仍然没有运气。

您需要将私钥（例如~/.ssh/id_rsa 或id_dsa）添加到VPS，然后将公钥添加到您的Github profile settings，以便能够通过ssh 验证和克隆您的repo。
