06.升级git版本及命令学习

博客为日常工作学习积累总结：

1.升级git版本：

参考博客：https://blog.csdn.net/yuexiahunone/article/details/78647565由于新的版本可以使用gitea功能所以升级git版本，centos7默认git版本如下：

[root@git ~]# git --version
git version 1.8.3.1

2.yum默认安装不适合生成环境需要编译安装此步奏忽略：

yum命令安装git是最简单的,直接键入命令安装就可以了


yum install git -yy


3.编译安装：

yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker


wget https://github.com/git/git/archive/v2.9.5.zip


unzip v2.9.5.zip

cd git-2.9.5

make prefix=/usr/local/git all

make prefix=/usr/local/git install

rm -rf /usr/bin/git

ln -s /usr/local/git/bin/git /usr/bin/git

git --version

 

 

[root@git git-2.9.5]# git --version
git version 2.9.5

 

4.初始化：

[root@git ~]# git config

git help

[root@git ~]# mkdir test

[root@git ~]# cd test/

[root@git learngit]# git init
Initialized empty Git repository in /root/learngit/.git/

[root@git learngit]# git config --list
core.repositoryformatversion=0
core.filemode=true
core.bare=false
core.logallrefupdates=true

5.配置git目录：

[root@git learngit]# git config --global user.name "Eric-xgc"
[root@git learngit]# git config --global user.email 741017474@qq.com

[root@git learngit]# git config --list
user.name=Eric-xgc
user.email=741017474@qq.com
core.repositoryformatversion=0
core.filemode=true
core.bare=false
core.logallrefupdates=true

6.git应用原理：

 图片来源老男孩教育郭宏泽

 

 

git add

git status

git status -s

git diff

git diff --staged

git commit

git reset

git rm

git rm --cached README

git mv

7.测试命令功能：

1.初始化后

[root@git test]# git status
On branch master

Initial commit

nothing to commit (create/copy files and use "git add" to track)

2.新增一个文件

[root@git test]# vim index.html
<h1>welcome to ht <h1>

[root@git test]# git status     
On branch master

Initial commit

Untracked files:
  (use "git add <file>..." to include in what will be committed)

        index.html

nothing added to commit but untracked files present (use "git add" to track)

3.提交一个文件到暂存区

[root@git test]# git add index.html
[root@git test]# git status        
On branch master

Initial commit

Changes to be committed:
  (use "git rm --cached <file>..." to unstage)

        new file:   index.html

4.提交到本地仓库

[root@git test]# git commit -m "first commit"
[master (root-commit) 6083db0] first commit
 1 file changed, 1 insertion(+)
 create mode 100644 index.html

[root@git test]# git status
On branch master
nothing to commit, working tree clean

5.查看提交日志

[root@git test]# git log
commit 6083db06d756ef50053cb439e55144242f95b5a8
Author: Eric-xgc <741017474@qq.com>
Date:   Mon Apr 1 14:31:43 2019 +0800

first commit

6.测试rm命令

[root@git test]# vim pay.html
pay modle

 

[root@git test]# git status
On branch master
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

        new file:   pay.html

[root@git test]# vim news.html
news center

[root@git test]# git add news.html

[root@git test]# git status   
On branch master
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

        new file:   news.html
        new file:   pay.html

[root@git test]# git rm --cached pay.html
rm 'pay.html'

[root@git test]# git status
On branch master
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

        new file:   news.html

Untracked files:
  (use "git add <file>..." to include in what will be committed)

        pay.html

 

[root@git test]# git commit -m "news"

7.分支管理

业务场景：当需要开发新的模块时会经常改动代码，不能影响主分支master

创建分支：about

git branch about

[root@git test]# git branch about

切换分支

git checkout about

[root@git test]# git checkout about
Switched to branch 'about'

[root@git test]# git status
On branch about
nothing to commit, working tree clean

 测试分支与主分支：

[root@git test]# vim about.html
about us

[root@git test]# git add .

[root@git test]# git commit -m "about"

测试about分支有4次提交

[root@git test]# git log

 回到测试分支

[root@git test]# git checkout about
Switched to branch 'about'
[root@git test]# git branch
* about
  master

[root@git test]# git branch -v
* about  6a24c25 about
  master 2e667e5 pay

8. 将测试分支合并到主分支：

 [root@git test]# vim about2.html
about2

[root@git test]# git add .
[root@git test]# git commit -m "about2"
[about 0283739] about2
 1 file changed, 1 insertion(+)

 9.checkerout命令

 

git checkerout  命令：用于切换分支。

[root@git test]# git checkout master

回滚本地目录修改的文件

git checkerout  -- 修改的文件

 git checkout -- index.html   

 测试用例：

[root@git test]# vim index.html
<h1>welcome to ht <h1>

22222

[root@git test]# git status     
On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

        modified:   index.html

no changes added to commit (use "git add" and/or "git commit -a")

[root@git test]#  git checkout -- index.html
[root@git test]# git status                  
On branch master
nothing to commit, working tree clean

修改被撤销了，

[root@git test]# cat index.html
<h1>welcome to ht <h1>

 

10.reset 回滚暂存区修改的文件

 

git log得到的id号
git reset --hard id号

所有的操作记录

[root@git test]# git reflog
