GitHub多账号管理踩坑记录

2018-07-24

背景

新增了一个Github账号，并push过代码，然后用以前的github账号push时，死活push不上去

寻找解决办法

使用ssh key

每个账号对应一个key, Github上填写对应的key（如：id_rsa.github.yl2014.pub文件内容）

# 生成key文件
ssh-keygen -t rsa -f ~/.ssh/id_rsa.github.yl2014 -C "yl2014@xx.com"
ssh-keygen -t rsa -f ~/.ssh/id_rsa.github.test -C "test@xx.com"

# 添加key文件
ssh-add ~/.ssh/id_rsa.github.yl2014
ssh-add ~/.ssh/id_rsa.github.test

# 配置config
vim ~/.ssh/config
Host yl2014
    HostName github.com
    IdentityFile ~/.ssh/id_rsa.github.yl2014
    User git

Host test
    HostName github.com
    IdentityFile ~/.ssh/id_rsa.github.test
    User git

# 测试
ssh -T yl2014
> Hi YL2014! You've successfully authenticated, but GitHub does not provide shell access.

ssh -T test
> Hi test! You've successfully authenticated, but GitHub does not provide shell access.

ssh -T git@github.com
> Hi YL2014! You've successfully authenticated, but GitHub does not provide shell access.

如果出现 ermission denied (publickey)，则表示key没添加成功，执行
ssh-add ~/.ssh/id_rsa.github.yl2014，或用debug模式查看具体出错信息ssh -vT git@github.com

如果发现推送时一直是某个GitHub账号，无法切换成另一个，可以采取如下操作：

1
2
3

# 删除所有session，并添加需要认证的
$ ssh-add -D
$ ssh-add id_rsa.github.yl2014
