Done is better than perfect...

同一台PC连接多个git服务器

同一台PC链接多个git服务器

1.在~/.ssh/目录下创建config文件
2.生成gitlab的公钥
    ssh-keygen -t rsa -C "qdyxmas@qq.com" -f ~/.ssh/id_rsa_lab
3.生成github的公钥
    ssh-keygen -t rsa -C "qdyxmas@gmail.com" -f ~/.ssh/id_rsa_hub
4.编辑config文件,把gitlab和github的信息输入
    Host github.com
        User qdyxmas@gmail.com
        Hostname ssh.github.com
        PreferredAuthentications publickey
        IdentityFile ~/.ssh/id_rsa_hub
        Port 443
    Host gitlab.com
      Hostname altssh.gitlab.com
      User qdyxmas@qq.com 
      Port 443
      PreferredAuthentications publickey
      IdentityFile ~/.ssh/id_rsa_lab
6.把公钥信息复制到gitlab(github)上
     ~/.ssh/id_rsa_lab.pub
7.测试是否正常ssh -vT git@gitlab.com
    root@qdyxmas:~/unittest# ssh -vT git@gitlab.com

8. jenkins上账号下载代码:
    在jenkins下的凭据=》全局凭据=》添加凭据
    选择SSH Username with private key
    username:填写凭据说明,比如gitlab_key
    私钥内容里面把~/.ssh/id_rsa_lab内容复制过来就OK
