Git如何生成多個ssh key添加到ssh-agent管理項目

生成新的ssh密鑰

ssh-keygen -t rsa -b 4096 -C "[email protected]"

不要一直回車鍵，輸入新的名稱 id_rsa_new

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

啓動ssh-agent

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

將SSH私鑰添加到ssh-agent並將密碼存儲在密鑰鏈中

ssh-add ~/.ssh/id_rsa_new

需要修改~/.ssh/config文件以自動將密鑰加載到ssh-agent中並在密鑰鏈中存儲密碼

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

回到GitHub賬號添加祕鑰不再複述
請看link

ssh -T git@new
測試鏈接，如下繼續連接 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，出現successfully表示成功

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

添加倉庫地址 Host 對應config中的配置
git remote add origin git@:xxxx/test.git

這樣就可以實現管理多個GitHub項目
win系統配置過程會出現更多問題，再敘。。
