Git的多账号如何处理? 1.同一台电脑多个git(不同网站的)账号 2.同一台电脑多个git(同一个网站的比如github的)多个账号

1.同一台电脑可以有2个git账号(不同网站的)

首先不同网站,当然可以使用同一个邮箱,比如我的github,gitlab,bitbucket的账号都是monkeysuzie[at]gmail.com 这时候不用担心密钥的问题,因为这些网站push pull 认证的唯一性的是邮箱 比如我的windows 上 2个账号一个gitlab 一个github (用的都是id_rsa)

host github
  hostname github.com
  Port 22

host gitlab.zjut.com
