清除配置

查看 Git 本地配置

Terminal window
git config --list

清除用户名和邮箱

Terminal window
git config --global --unset user.name
git config --global --unset user.email

生成 ssh-key

使用 ssh-keygen 命令生成 ssh-key，并手动指定 id

Terminal window
ssh-keygen -t rsa -f ~/.ssh/id_rsa_xx1@gmail.com -C "xx1@gmail.com"

生成成功会输出以下内容

Terminal window
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/james/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/james/.ssh/id_rsa.
Your public key has been saved in /Users/james/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:rwtxjGTJPoV9Mg8lFSf8D4X6jFexWVXKOMRaVyo+RO8 xx1@gmail.com
The key's randomart image is:
+---[RSA 3072]----+
|        .o=o+. .*|
|     . + o.=+++o.|
|      * * .==o== |
|     + + *ooo++  |
|      = S .+o+E  |
|       + .. +..  |
|      .   ..     |
|       . .       |
|        o.       |
+----[SHA256]-----+

然后继续生成你的其他 Git 账号对应的 ssh-key

Terminal window
ssh-keygen -t rsa -f ~/.ssh/id_rsa_xx2@gmail.com -C "xx2@gmail.com"

信任 ssh-key

使用 ssh-add 命令将生成的 ssh-key 添加到 ssh-agent 信任列表

Terminal window
ssh-add ~/.ssh/id_rsa_xx1@gmail.com
ssh-add ~/.ssh/id_rsa_xx2@gmail.com

如果遇到 Could not open a connection to your authentication agent. ，输入

Terminal window
ssh-agent bash

然后重复执行 ssh-add 即可解决

配置公钥

复制对应公钥，配置到对应 Git 网站中（GitHub / GitLab）

Terminal window
pbcopy < ~/.ssh/id_rsa_xx1@gmail.com.pub
pbcopy < ~/.ssh/id_rsa_xx2@gmail.com.pub

这步具体的操作如果有不清楚的可以参考 Adding a new SSH key to your GitHub account

配置 config

进入 ssh 目录

Terminal window
open ~/.ssh/

按照以下规则编辑 config 文件，没有则创建

键值说明
Host主机自己起
Hostname主机名Git 公有地址，比如 gitub.com / gittee.com
IdentityFile身份文件rsa 文件路径
User用户自己起，一般邮箱就好

编辑完 config 内容如下

Terminal window
Host github1.com
Hostname github.com
IdentityFile ~/.ssh/id_rsa_xx1@gmail.com
User xx1@gmail.com


Host github2.com
Hostname github.com
IdentityFile ~/.ssh/id_rsa_xx2@gmail.com
User xx2@gmail.com

测试链接

测试 Git 账号是否连接成功，git@ 之后是 config 文件中配置的 Host

Terminal window
ssh -T git@github1.com
ssh -T git@github2.com

连接成功会有以下输出

Terminal window
Hi xxx! You've successfully authenticated, but GitHub does not provide shell access.
