I have the following use case: I would like to be able to push to git@git.company.com:gitolite-admin using the private key of user gitolite-admin, while I want to push to git@git.company.com:some_repo using 'my own' private key. AFAIK, I can't solve this using ~/.ssh/config, because the user name and server name are identical in both cases. As I mostly use my own private key, I have that defined in ~/.ssh/config for git@git.company.com. Does anyone know of a way to override the key that is used for a single git invocation?
(另外:gitolite根据键来区分谁在进行推送，所以就访问、所有权和审计而言，user@server字符串对于不同的用户是相同的，这不是问题。)
以下是简单的方法:
-从你的本地根git文件夹。
-检查当前本地存储库的认证方法类型为HTTPS或SSH。
git remote -v
Example using HTTPS:
origin https://github.com/juantorres9/SQLite_crash_cours.git (fetch)
origin https://github.com/juantorres9/SQLite_crash_cours.git (push)
Example using SSH:
origin git@github.com:juantorres9/SQLite_crash_cours.git (fetch)
origin git@github.com:juantorres9/SQLite_crash_cours.git (push)
-设置您选择的身份验证方法，以防尚未设置。
For setting SSH
git remote set-url origin git@github.com:USERNAME/REPOSITORY.git
For setting HTTPS
git remote set-url origin https://github.com/USERNAME/REPOSITORY.git
-再检查一遍以防你想再次检查
git remote -v
-你现在可以使用你配置的方法来使用git push:fetch。
git push origin master
请注意
最后但并非最不重要的，检查更新的官方文件

正如其他人提到的，核心。sshCommand config可以覆盖SSH密钥和其他参数。
下面是一个示例，其中有一个名为~/的替代键。Ssh /workrsa，并希望将其用于~/work下克隆的所有存储库。
在~/work下创建一个新的.gitconfig文件:
[core]
sshCommand = "ssh -i ~/.ssh/workrsa"
在全局git配置中~/。gitconfig,添加:
[includeIf "gitdir:~/work/"]
path = ~/work/.gitconfig
我在Win7上使用Git Bash。下面的方法对我很有效。
在~/处创建一个配置文件。Ssh /config或c:/users/[your_user_name]/. Ssh /config。在文件中输入:
Host your_host.com
IdentityFile [absolute_path_to_your_.ssh]\id_rsa
我想主机必须是一个URL，而不仅仅是一个“名称”或参考您的主机。例如,
Host github.com
IdentityFile c:/users/[user_name]/.ssh/id_rsa
也可以写入“/c/users/[user_name]/....”格式
Giordano Scalzo提供的解决方案也很棒。
