同时配置多个 git 账号

多个账号配置 ssh

1. 生成公私钥

   ssh-keygen -t rsa -C "邮箱地址" -f ~/.ssh/work_id_rsa
   ssh-keygen -t rsa -C "邮箱地址" -f ~/.ssh/github_id_rsa

2. 公钥（*.pub）copy到平台上

   cat ~/.ssh/work_id_rsa.pub
   cat ~/.ssh/github_id_rsa.pub

3. 修改config文件

   Host work.domain.com
     HostName work.domain.com
     User git
     IdentityFile ~/.ssh/work_id_rsa
   
   Host github.com
       HostName github.com
       IdentityFile ~/.ssh/github_id_rsa

测试配置结果

ssh -T git@github.com
