linux - 在Linux服务器上设置git

Question

我正在尝试在运行 Linux RedHat 的服务器上设置 git 存储库。

我按照 Github 帮助页面上的说明进行操作。我到达了指示告诉我通过 ssh 访问 git@github.com 的步骤。

这给了我以下错误 -

 $ ssh -T git@github.com
 Permission denied (publickey).

然后我做了 $ ssh -vT git@github.com 并得到了这个 -

 OpenSSH_5.3p1, OpenSSL 1.0.0-fips 29 Mar 2010

这就是我现在所在的位置 -

 $ pwd
 /home/min/a/foo/.ssh

我不明白这是怎么回事？另外，如果我尝试通过 ssh-add 添加此路径，它会显示“无法打开与您的身份验证代理的连接”。

您似乎尚未将 key 上传到 github，或者您上传的 key 与当前用户的默认 key 不匹配。

检查您的本地 key 是否在 github 上:

• 获取 key 指纹:ssh-keygen -lf ~/.ssh/id_rsa.pub
• 根据 github 上允许的 key 列表检查此内容:https://github.com/settings/ssh

或者，检查您的 key 是否已在 github 上启用。不久前，有一个security issue related to ssh keys on github 。所有 ssh key 均被禁用，以强制用户检查其允许的 key 列表。如果您最近没有使用过 github，您的 github 仍可能被禁用。
