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。)

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 

其他回答

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

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

你可以使用git环境变量GIT_SSH_COMMAND。在你的终端git仓库下运行:

GIT_SSH_COMMAND='ssh -i ~/.ssh/your_private_key' git submodule update --init

取代~ /。Ssh /your_private_key与你想使用的Ssh私钥路径。你可以将后续的git命令(本例中是git子模块update——init)更改为其他命令,如git pull、git fetch等。
