Git如何生成多个ssh key添加到ssh-agent管理项目

Git如何生成多个ssh key添加到ssh-agent管理项目
生成新的ssh密钥

ssh-keygen -t rsa -b 4096 -C "your@example.com"

不要一直回车键，输入新的名称 id_rsa_new

Enter a file in which to save the key (/Users/you/.ssh/id_rsa):id_rsa_new

启动ssh-agent

$ eval "$(ssh-agent -s)" > Agent pid 59566

需要修改~/.ssh/config文件以自动将密钥加载到ssh-agent中并在密钥链中存储密码
Mac系统如下

Host new HostName github.com AddKeysToAgent yes UseKeychain yes IdentityFile ~/.ssh/id_rsa_new User test Host old HostName github.com AddKeysToAgent yes UseKeychain yes IdentityFile ~/.ssh/id_rsa User test

Win系统如下

Host new HostName github.com IdentityFile C:\\Users\Eric\.ssh\id_rsa_new PreferredAuthentications publickey User Eric Host old HostName github.com IdentityFile C:\\Users\Eric\.ssh\id_rsa PreferredAuthentications publickey User Eric

将SSH私钥添加到ssh-agent并将密码存储在密钥链中
Mac系统如下

ssh-add ~/.ssh/id_rsa_new

Win系统如下

ssh-add C:\\Users\Eric\.ssh\id_rsa_new

Win系统 ssh-add 可能出现报错看这里解决

回到GitHub账号
添加ssh key看这里

ssh -T git@new
测试链接，如下继续连接 yes

> The authenticity of host 'github.com (IP ADDRESS)' can't be established. > RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48. > Are you sure you want to continue connecting (yes/no)?

或

> The authenticity of host 'github.com (IP ADDRESS)' can't be established. > RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8. > Are you sure you want to continue connecting (yes/no)?

如下，出现successfully表示成功

> Hi username! You've successfully authenticated, but GitHub does not > provide shell access.

添加仓库地址 Host 对应config中的配置
git remote add origin git@:xxxx/test.git

这样就可以实现管理多个GitHub项目，多看官方文档，结合官方文档解决问题更高效
Win系统可能出现很多问题，Mac有时候更好用呢，熬了两个晚上把Mac和Win系统问题解决分享出来，用你那高冷的方式点个赞吧
