创建另一个 github 帐户并添加新 ssh 导致的 ssh 问题

Question

我创建了一个新的 github 帐户，因此我需要一个新的 ssh 密钥，但是在正确设置 ssh 密钥后，我无法推送我的项目。 创建新的 ssh 密钥后，我在 .ssh 目录中添加了一个配置文件，如下所示：

# one(one@gmail.com)

Host eric

HostName github.com

IdentityFile ~/.ssh/id_rsa

User eric



# two(two@ gmail.com)

Host nuist

HostName github.com

IdentityFile ~/.ssh/github_id

User nuist

然后我运行：ssh -T -v nuist，收到以下指令：

OpenSSH_8.3p1, OpenSSL 1.1.1g  21 Apr 2020

但是，运行我：ssh -T git@github.com 之后，竟然成功了。

我猜测配置文件不起作用，但不能确定。

我看不出问题出在哪里，我也已经在我的 github 帐户中设置了 ssh。

有人可以帮忙吗？我真的很感激。

Answer 1

您不需要新帐户的新密钥，只需将您的另一个 ID 添加为具有完全访问权限的协作者。

如果以这种方式进行测试，您访问 github 的配置应为两个主机使用 User git。

运行 ssh-add -l 以检查密钥是否已加载。

运行git remote -v 来检查 github fetch/push url，看看它们是否与 github 提供的 ssh 链接匹配。

如果不匹配，可以用git remote set-url origin <github-ssh-url>设置替换成github说的链接。
