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。)

您可能需要删除(或注释掉)默认的主机配置

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

注意:有一种方法可以在之前的回答中应用目录的git配置,而不仅仅是在回购级别。

在我的例子中,所有的项目都在~/work/目录下,所以我更新了我的gitconfig如下:

# ~/.gitconfig
...

[includeIf "gitdir:~/work/**"]
  path = "~/work/.gitconfig"
# ~/work/.gitconfig
[user]
  email = amr@work.com
  name = Amr Awad
  sshCommand = ssh -i ~/.ssh/work

现在~/work/目录下的所有回购操作都使用工作键~/。Ssh /work,不需要分别配置每个repo。

对于git来说,除了更改配置文件,它应该使用不同的SSH密钥,如下所述: https://stackoverflow.com/a/7927828/1306884 您可能还需要清除并重新加载活动的SSH标识。

在Mac上,执行以下操作:

ssh-add -D
ssh-add ~/.ssh/id_rsa_one_that_you_want_to_use_instead

使用这两个命令,并设置GIT URL以匹配ssh/config文件的Host中定义的字符串,应该允许您为不同的存储库使用不同的ssh密钥。

例如,对于主机work.github.com,在克隆存储库时使用work.github.com作为URL git@work.github.com:your/repository.git。

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"
