两台机器A开发人员客户端，机器B（192.168.12.53）存放git代码服务器。
A机器生成公钥
（本文使用gitbash，使用cmd亦可）
ssh-keygen -t rsa -b 2048 -C "your_email"
cat /c/Users/admin/.ssh/id_rsa.pubB代码服务器
添加公钥
sudo adduser git
su git
cd
mkdir .ssh && chmod 700 .ssh
touch .ssh/authorized_keys && chmod 600 .ssh/authorized_keys
vi ~/.ssh/authorized_keys
初始化仓库
mkdir project.git
cd project.git
git init --bareA机器克隆仓库，提交代码
