一台电脑同时使用GitLab和GitHub仓库

到不同的国家要用不同的货币。同一台电脑 想要同时使用GitHub和GitLab，那么到GitHub家自然要用GitHub的钥匙才能开门，到GitLab家就要用GitLab家的钥匙。那么要做的有两点：

1. 用Git生成两把钥匙；

#GitHub的钥匙

# kingboy @ KingBoydeMacBook-Pro in ~/.ssh [7:50:33]
➜  ssh-keygen -t rsa -C "kingboy@163.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/kingboy/.ssh/id_rsa): /Users/kingboy/.ssh/github_id_rsa
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/kingboy/.ssh/github_id_rsa.

The key fingerprint is:

The key's randomart image is:

注意：

Enter file in which to save the key (/Users/kingboy/.ssh/id_rsa): /Users/kingboy/.ssh/github_id_rsa

输入的是钥匙的位置和名称。github和gitlab是不同的。

完成后会在~/.ssh/目录下生成以下文件:

github_id_rsa

github_id_rsa.pub

gitlab_id_rsa

gitlab_id_rsa.pub

将两个pub文件分别配置到github和gitlab的sshkey中

2. 编写config文件,告诉本地git到不同的国家带不同的钥匙。

例如：

github地址:github.com
gitlab地址:gitlab.max.com

执行以下命令:

cd ~/.ssh
vim config

config内容如下:(HostName根据自己实际需求来定)

#gitlab
Host gitlab
HostName gitlab.*.com
IdentityFile ~/.ssh/gitlab_id_rsa

#github
Host github
HostName github.com
IdentityFile ~/.ssh/github_id_rsa

3. 配置仓库

例如:

github工作仓库:~/workspace/github
gitlab工作仓库:~/workspace/gitlab

#gitlab
cd ~/workspace/gitlab
git init
git config --global user.name 'personal'
git config --global user.email 'personal@company.com'

#github
cd ~/workspace/github
git init
git config --local user.name 'kingboy'
git config --local user.email 'kingboy@163.com'

接下来在两个目录下新建或者clone项目开发即可.
