git 权限被拒绝(公钥)

Question

当我想设置 ssh 到我的 git 时遇到了一些问题。这是我收到的错误消息。

mbp-op-159:.ssh weiting.cheng$ ssh -vT git@github.com

我按照 git hub 文档上的说明进行操作，但他们没有提到我的问题。

我有私钥

debug1: identity file /Users/c/.ssh/id_rsa type 1

我还将 key 添加到我的 git hub 帐户

git成功获取到我的私钥

debug1: Authentications that can continue: publickey
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /Users/c/.ssh/id_rsa

但由于未知原因，git 继续使用我没有生成的 id_dsa。

debug1: Authentications that can continue: publickey
debug1: Trying private key: /Users/c/.ssh/id_dsa
debug1: No more authentication methods to try.

然后我的权限被拒绝了。

有人有解决这个问题的建议吗？

Answer 1

您的 key 无效。我建议完全重新开始，所以请继续并删除 ~/.ssh/ 文件夹中的所有内容(known_hosts 除外，您可能应该保留它)。然后运行:

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

使用与您的 GitHub 帐户关联的电子邮件地址。确保 key 保存在正确的用户文件夹中。在您的情况下， key 应保存为 /Users/c/.ssh/id_rsa。

最后，将 ~/.ssh/id_rsa.pub 的内容复制到剪贴板。转到您的 GitHub 设置，单击 SSH key 选项卡，然后添加您刚刚复制的 key 。
