//本环境为os下
//首先是查看本机安装git版本
yangliu$ git --version
git version 2.17.0
//git目录
yangliu$ which git
/usr/local/bin/git
//生成git用户名和邮箱
yangliu$ git config --global user.name "renyu" //里面是自己的用户名
yangliu$ git config --global user.email "ren**@163.com" //里面是自己的邮箱
//查看是否已经有密钥，我这里之前没有，有的话用就可以咯
yangliu$ cd ~/.ssh
-bash: cd: /Users/yangliu/.ssh: No such file or directory
//生成根，输入下面的命令后 三个回车，其中有输入密码，这里有一步就是密码为空
yangliu$ ssh-keygen -t rsa -C "ren****@163.com"

可以把生成的公钥放到github上就可以上传到他那里啦 ，也可以添加到你们公司的authorized_keys上。
