在工作中，我们可能需要将代码推送到公司内部的自建 Git 代码托管平台（如 GithLab）。与此同时，日常开发过程中，我们也常常需要将代码提交到社区的 Git 代码托管平台（如 Github 等）。提交到 github 又需要管理多个 github 账号

解决

用过~/.ssh/config配置多个不同的 SSH 认证

# 公司github
ssh-keygen -t rsa -C "YourCompanyEmailAdress"
# 输入密钥的名称: id_rsa_company
Enter file in which to save the key (/Users/username/.ssh/id_rsa): id_rsa_company

# github1
ssh-keygen -t rsa -C "GithubEmail1"
# 输入密钥的名称: id_rsa_github
Enter file in which to save the key (/Users/username/.ssh/id_rsa): id_rsa_github_1

# github12
ssh-keygen -t rsa -C "GithubEmail2"
# 输入密钥的名称: id_rsa_github
Enter file in which to save the key (/Users/username/.ssh/id_rsa): id_rsa_github_2

# `~/.ssh/config
# 小号github
Host xx.github.com # 小号
    User git
    Hostname github.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa_github_2
    
# 默认github
Host github
    User git
    Hostname github.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa_github_1

Host company-git
    User git
    # 替换为公司的 Git 代码托管平台的服务器
    Hostname company-git-repo.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/id_rsa_company

大号不变，小号 clone 使用 host匹配
git clone git@xx.github.com:xxxx/xxx.git

添加

ssh-add ~/.ssh/id_rsa_github_1

仓库级别配置 git 提交信息

git config user.name xxx && git config user.email xxxx@qq.com 

git配置``

# 全局
cat ~/.gitconfig 
# 仓库
cat .git/config
