Git配置多个SSH

1.Git初始化、私钥生成参考生成 ssh key

2.配置多个SSH key

找到你的git安装目录下的/etc,修改profile文件，在后面添加

Hello, dear Git developer.

This is a minimal MSYS environment to work on Git.

In order to use Git from cmd.exe:
1. Add c:\msysgit\cmd to cmd's PATH
2. DON'T add c:\msysgit\bin or c:\msysgit\mingw\bin to cmd's PATH
Commands like 'git add' will work from cmd.exe now.
Commands like 'git-add' will NOT work. Add more wrappers as appropriate.

eval $(ssh-agent -s)
ssh-add ~/.ssh/id_rsa
ssh-add ~/.ssh/gitee_rsa

eval $(ssh-agent -s)
ssh-add ~/.ssh/id_rsa
ssh-add ~/.ssh/gitee_rsa

这样每次打开Git Bash时就会在添加私钥匙
