一篇博客带你上手Git

概述

安装Git

下载官方网站，下载后安装包样式：双击安装，安装成功后右键文件会有如下选项证明安装成功。

基本配置

设置用户信息，桌面右键，选择Git bash here

hecheng@LAPTOP-OJQFEH00 MINGW64 ~/Desktop

$ git config --global user.name "hecheng"

hecheng@LAPTOP-OJQFEH00 MINGW64 ~/Desktop

$ git config --global user.email "hecheng@qq.com"

自己编写自己的用户名和邮箱，之后可以查看，效果如下

基本操作

创建文件——>提交到缓存区——>提交到仓库

分支创建原则

master，主分支，用于发行的版本，develop，开发的分支，feature（可以删除），功能的分支，hotfix，修复bug的分支，feature合并到develop，develop合并到master，用户反馈到bug，创建hotfix分支，写好修复代码后，分别合并到master分支和develop分支。

四、远程仓库

1.

创建码云账户，创建仓库，获取公匙。

再连接本地仓库与远程仓库（添加远程仓库：git remote add 远端名称仓库路径），查看远程仓库，将代码推送到远程仓库（git push 远端名称本地分支名：远端分支名），查看关联关系：git branch -vv

hecheng@LAPTOP-OJQFEH00 MINGW64 /e/GitTest (master)

$ git remote add origin git@gitee.com:hecheng11223/git_-test.git

hecheng@LAPTOP-OJQFEH00 MINGW64 /e/GitTest (master)

$ git push origin master:master

Everything up-to-date

hecheng@LAPTOP-OJQFEH00 MINGW64 /e/GitTest (master)

$ git push --set-upstream origin master

branch 'master' set up to track 'origin/master'.
