一台电脑，多个Github Accounts(用SSH链接)

痛点： 一台电脑，多个Github账户。

解决方案： 最简单的办法，通过设置collaborator，让一个账户开发多个项目。所有工作计入这个账户下面。问题，分帐户记账麻烦了。

所以，有了如下方案： 参考链接：docs.github.com/en/account-…

1. create SSH key

ssh-keygen -t ed25519 -C "aigenerated1@gmail.com"
ssh-keygen -t ed25519 -C "aigenerated2@gmail.com"
ssh-keygen -t ed25519 -C "aigenerated3@gmail.com"

2. Run ssh agent:

这个必须用有admin的powershell。

# start the ssh-agent in the background
Get-Service -Name ssh-agent | Set-Service -StartupType Manual
Start-Service ssh-agent

3. Add SSH key to ssh-agent

ssh-add c:/Users/YOU/.ssh/aisshname1
ssh-add c:/Users/YOU/.ssh/aisshname2
ssh-add c:/Users/YOU/.ssh/aisshname3

加完后可以用ssh-add -L查看一下结果。

4. Add the SSH public key to your account on GitHub. For more information, see "Adding a new SSH key to your GitHub account."

5. .ssh下生成config文件如下：

# Default github account: ai1
Host github.com
   HostName github.com
   IdentityFile ai1
   IdentitiesOnly yes
   
# Other github account: ai2
Host github.com-ai3
	HostName github.com
	User git
	IdentityFile ai2
   
# Other github account: ai3
Host github.com-ai3
   HostName github.com
   IdentityFile ./ai3
   IdentitiesOnly yes

6. Test the SSH Connection:

$ ssh -T git@github.com
# Attempts to ssh to GitHub

$ ssh -T git@github.com-ai3
$ ssh -T git@github.com-ai2

返回：

Warning: Permanently added 'github.com' (ED25519) to the list of known hosts.
