一、下载安装Git
1、下载Git 官方地址为：https://git-scm.com/download/win
2、下载完之后，双击安装
3、选择安装目录
4、选择组件
5、开始菜单目录名设置
6、以下步骤依次执行
7、安装完成
9、检验是否安装成功
回到电脑桌面，鼠标右击如果看到有两个git单词则安装成功
二、Git初始化操作
1、Git安装之后需要进行一些基本信息设置
a、设置用户名：git config -- global user.name '你再github上注册的用户名';
b、设置用户邮箱：git config -- global user.email '注册时候的邮箱';
注意：该配置会在github主页上显示谁提交了该文件
c、配置ok之后，我们用如下命令来看看是否配置成功
git config --list
注意：git config --global 参数，有了这个参数表示你这台机器上所有的git仓库都会使用这个配置，当然你也可以对某个仓库指定不同的用户名和邮箱
以下是一些字符等参数配置：
git config --global core.autocrlf false
#让git不要管win/unix换行符转换的事
git config --global gui.encoding utf-8
#避免git gui中的中文乱码
git config --global core.quotepath off
#避免git status 显示的中文文件名称乱码
window中配置：
git config --global core.ignorecase false
1.ssh key pair配置
ssh-keygen -t rsa -C "a454902046@163.com"
然后一路回车，不要输入任何密码，生成ssh key pair
2.公钥添加到github账号：
3.下载自己的代码：
git clone git@github.com:pinghengxing/shoping.git
如果出现以上提示，按照提示，在hosts【C:WindowsSystem32driversetchosts】中添加以下内容并重试重试：
13.250.177.223 github.com
基本命令:
git branch
#显示本地分支
git branch -r
#显示远程分支
git checkout 分支名称
#切换到对应分支
git pull
#拉取
#git push
#提交
三、Git克隆操作
目的：将远程仓库（github上对应的项目）复制到本地
1、代码：git clone 仓库地址
仓库地址由来如下：
2、克隆项目
3、将本地仓库同步到git远程仓库中：git push
或者如下示例：：
四、git本地创建仓库提交代码过程
