简单的方法，不需要处理SSH键盘

只需更改user.name & user。在回购的本地电子邮件。给那些你想要推到回购的人。

示例:我在gitlab有一个工作帐户，有一个项目。克隆这个项目/回购后，在终端中，我输入:

git config user.name "my-work-username"
git config user.email "my-work-email-id"

现在，假设我在Gitlab中有另一个个人项目/回购，我想将它与我的个人帐户关联起来。就像上面一样，克隆后，我输入:

git config user.name "my-personal-username"
git config user.email "my-personal-email-id"

希望这能有所帮助。如果对你有用就给它点赞!：）

让我的私人回购工作使用SSH密钥对。这是在Windows git上测试的。

来源:https://docs.github.com/en/free-pro-team@latest github / authenticating-to-github / generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent

A.生成公钥和私钥对

启动git bash 执行ssh-keygen -t ed25519 -C "your_email@example.com" 当提示您“输入要保存密钥的文件”时，按Enter接受默认值。 按enter键输入空白密码。 启动ssh代理:eval $(ssh-agent) 将私钥添加到ssh代理，并存储密码:ssh- Add ~/.ssh/id_ed25519

B.添加SSH密钥到GitHub账户

将公钥复制到剪贴板:clip < ~/.ssh/id_ed25519.pub 在GitHub中，进入“配置文件->设置-> SSH密钥-> SSH新密钥” 给出一个标题。如。“MacBook Pro上的Windows” 粘贴密钥并点击“添加SSH密钥”。

C.测试SSH连接

输入:ssh -T git@github.com 点击“是”查看任何警告信息。 它应该显示:“Hi username!…”，表示测试成功。

D.设置本地存储库以使用SSH密钥

更改邮箱和用户名:

git config user.email your_email@example.com
git config user.name github_username

更新远程链接以使用git。首先列出远程URI:

git remote -v
git remote set-url origin git@github.com:github_username/your-repo-name.git

e .测试

git remote show origin

以防你不想弄乱~/。这里提到的Ssh /config文件，你可以运行git config core。ssh -i ~/.使用实例Ssh /custom_id_rsa”，你想从一个不同的帐户提交。

其余的设置是相同的:

使用SSH -keygen -t rsa -f ~/为第二个帐户创建新的SSH密钥。SSH -f ~/.ssh/custom_id_rsa 使用您的其他帐户登录github，转到https://github.com/settings/keys，并粘贴~/.ssh/custom_id_rsa.pub的内容 确保您使用SSH而不是HTTPS作为远程url: git remote set-url origin git@github.com:upstream_project_teamname/upstream_project.git

如果您已经创建或克隆了另一个存储库，并且无法从原点或上游提取，则使用以下命令在该目录中添加ssh密钥是有效的。

这是我得到的错误:

Warning: Permanently added the RSA host key for IP address '61:fd9b::8c52:7203' to the list of known hosts.
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

我使用了下面的命令，这是有效的:

ssh-add ~ / . ssh / id_rsa_YOUR_COMPANY_NAME

这个答案是给初学者的(非git大师)。我最近遇到了这个问题，也许这只是我的问题，但大多数答案似乎需要对git有相当深入的了解。在阅读了包括这个线程在内的几个堆栈溢出的答案后，下面是我需要采取的步骤，以便在GitHub帐户之间轻松切换(例如，假设有两个GitHub帐户，github.com/personal和gitHub.com/work):

Check for existing ssh keys: Open Terminal and run this command to see/list existing ssh keys ls -al ~/.ssh files with extension .pub are your ssh keys so you should have two for the personal and work accounts. If there is only one or none, its time to generate other wise skip this.- Generating ssh key: login to github (either the personal or work acc.), navigate to Settings and copy the associated email.now go back to Terminal and run ssh-keygen -t rsa -C "the copied email", you'll see:Generating public/private rsa key pair. Enter file in which to save the key (/.../.ssh/id_rsa): id_rsa is the default name for the soon to be generated ssh key so copy the path and rename the default, e.g. /.../.ssh/id_rsa_work if generating for work account. provide a password or just enter to ignore and, you'll read something like The key's randomart image is: and the image. done.Repeat this step once more for your second github account. Make sure you use the right email address and a different ssh key name (e.g. id_rsa_personal) to avoid overwriting. At this stage, you should see two ssh keys when running ls -al ~/.ssh again. Associate ssh key with gitHub account: Next step is to copy one of the ssh keys, run this but replacing your own ssh key name: pbcopy < ~/.ssh/id_rsa_work.pub, replace id_rsa_work.pub with what you called yours.Now that our ssh key is copied to clipboard, go back to github account [Make sure you're logged in to work account if the ssh key you copied is id_rsa_work] and navigate toSettings - SSH and GPG Keys and click on New SSH key button (not New GPG key btw :D) give some title for this key, paste the key and click on Add SSH key. You've now either successfully added the ssh key or noticed it has been there all along which is fine (or you got an error because you selected New GPG key instead of New SSH key :D). Associate ssh key with gitHub account: Repeat the above step for your second account. Edit the global git configuration: Last step is to make sure the global configuration file is aware of all github accounts (so to say). Run git config --global --edit to edit this global file, if this opens vim and you don't know how to use it, press i to enter Insert mode, edit the file as below, and press esc followed by :wq to exit insert mode: [inside this square brackets give a name to the followed acc.] name = github_username email = github_emailaddress [any other name] name = github_username email = github_email [credential] helper = osxkeychain useHttpPath = true

完成了!现在，当尝试从一个回购中推或拉，你会被问到哪个GitHub账户应该与这个回购链接，它只被问到一次，本地配置将记住这个链接，而不是全局配置，所以你可以在不同的回购上工作，链接到不同的账户，而不必每次编辑全局配置。

导航到要将更改推到另一个GitHub帐户的目录。 在终端/命令行中创建一个新的SSH密钥。 ssh-keygen -t rsa -C " your-email-address " 下面将显示: 生成rsa公私钥对。 输入保存密钥的文件(/home/your_username/.ssh/id_rsa):

复制并粘贴路径，后面跟着一个可识别的文件名:

/home/your_username/.ssh/id_rsa_personal

4)然后它会问你以下问题:

Enter passphrase (empty for no passphrase):
Enter same passphrase again:

5)您现在可以输入以下命令查看您在本地机器上拥有的所有SSH密钥:

ls -al ~/.ssh

您应该能够看到新的SSH密钥文件。正如你可以看到在我的一个，我有id_rsa_test和id_rsa_personal.pub。

drwx------  2 gmadmin gmadmin 4096 Nov 16 22:20 .
drwxr-xr-x 42 gmadmin gmadmin 4096 Nov 16 21:03 ..
-rw-------  1 gmadmin gmadmin 1766 Nov 16 22:20 id_rsa_personal
-rw-r--r--  1 gmadmin gmadmin  414 Nov 16 22:20 id_rsa_personal.pub
-rw-r--r--  1 gmadmin gmadmin  444 Nov  6 11:32 known_hosts

6)接下来需要复制存储在id_rsa_personal中的SSH密钥。酒吧文件。您可以在您选择的文本编辑器中打开此文件。我目前正在使用atom，所以我使用以下命令打开文件:

atom ~/.ssh/id_rsa_personal.pub

然后你会得到类似这样的结果:

ssh-rsa AAB3HKJLKC1yc2EAAAADAQABAAAAQCgU5+ELtwsKkmcoeF3hNd7d6CjW+dWut83R/DC01E/YzLc5ZFri18doOwuQoeTPpmIRVDGuQQsZshjDrTkFy8rwKWMlXl7va5olnGICcpg4qydEtsW+MELDmayW1HHsi2xHMMGHlNv

7)复制并导航到您的GitHub帐户→设置→SSH和GPG密钥 8)单击“新建SSH密钥”。复制键，给它一个标题并添加它。 9)从终端添加密钥

ssh-add ~/.ssh/id_rsa_personal
Enter passphrase for /home/your_username/.ssh/id_rsa_personal: 

10)配置用户和密码。

git config --global user.name "gitusername"
git config --global user.email "gitemail"

11)我们已经做好了承诺和推进的准备。

git init
git add .
git commit 
git push
