指定指定域的git push的SSH密钥

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。)

当前回答

即使用户和主机是相同的，在~/.ssh/config中仍然可以区分它们。例如，如果你的配置是这样的:

Host gitolite-as-alice
  HostName git.company.com
  User git
  IdentityFile /home/whoever/.ssh/id_rsa.alice
  IdentitiesOnly yes

Host gitolite-as-bob
  HostName git.company.com
  User git
  IdentityFile /home/whoever/.ssh/id_dsa.bob
  IdentitiesOnly yes

然后在URL中使用gitolite-as-alice和gitolite-as-bob代替主机名:

git remote add alice git@gitolite-as-alice:whatever.git
git remote add bob git@gitolite-as-bob:whatever.git

Note

您希望包括IdentitiesOnly yes选项，以防止使用默认id。否则，如果您也有与默认名称匹配的id文件，它们将首先被尝试，因为与其他配置选项(遵守“first in wins”)不同，IdentityFile选项附加到要尝试的身份列表中。参见:https://serverfault.com/questions/450796/how-could-i-stop-ssh-offering-a-wrong-key/450807 # 450807

你最多在文件配置键ssh中指定:

# Default GitHub user
Host one
 HostName gitlab.com
 User git
 PreferredAuthentications publickey
 IdentityFile ~/.ssh/key-one
 IdentitiesOnly yes

#two user
Host two
 HostName gitlab.com
 User git
 PreferredAuthentications publickey
 IdentityFile ~/.ssh/key-two
 IdentitiesOnly yes

如果你已经有默认的ssh密钥配置，但想要对特定的存储库使用不同的配置，那么这应该可以做到:

git config core.sshCommand "ssh -i ~/.ssh/github-personal -o IdentitiesOnly=yes -F /dev/null"

您可能需要删除(或注释掉)默认的主机配置

如果在windows上使用Git版本的ssh, ssh配置中的身份文件行如下所示

IdentityFile /c/Users/Whoever/.ssh/id_rsa.alice

其中/c代表c:

要检查，在git的bash做

cd ~/.ssh
pwd

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
