通过添加多密钥实现

• ssh-agent bash
• ssh-keygen -t rsa -C ‘xx1’ -f ~/.ssh/id_rsa_xx1
• ssh-keygen -t rsa -C ‘xx2’ -f ~/.ssh/id_rsa_xx2
• ssh-add id_rsa_xx1
• ssh-add id_rsa_xx2

vim ~/.ssh/config

Host github_xx1HostName github.comUser gitIdentityFile ~/.ssh/id_rsa_xx1
Host github_xx2HostName github.comUser gitIdentityFile ~/.ssh/id_rsa_xx2

• ssh -T -ai ~/.ssh/id_rsa_xx1 git@github_xx1
• ssh -T -ai ~/.ssh/id_rsa_xx2 git@github_xx2
