同时使用多个Git账号

Git比较详细介绍(简书文章)

使用git需要创建sshkey. 否则无法完成对远程仓库的clone push等操作.
sshkey目录在 ~/.ssh

step1: 创建新的 sshkey

终端输入

ssh-keygen -t rsa -C 'Email@mail.com' -f ~/.ssh/id_rsa_oschina

step2 : 创建配置文件 config

vi ~/.ssh/config

内容 :

Host git.oschina.net    #git.oschina.net  
    HostName git.oschina.net   
    User git      
    IdentityFile ~/.ssh/id_rsa_osc   
  
Host github.com   #github.com  
    HostName        github.com  
    User            git  
    IdentityFile   ~/.ssh/id_rsa  
      

step3: 连接本地和git远程仓库

ssh -T git@XXXXX.com 

step4: 连接本地仓库master和远程master分支

此时就已经和远程仓库联系上了. 但当时出了这样一个问题.
pathspec master did not match any file(s) known to git
原来本地的maste分支还不能和远程的master分支建立追踪关系
Git使用之(pathspec master did not match any file(s) known to git)

 git branch -u origin/master master
