自動化部署之Git基礎

自動化部署 git
GIT基礎
GIT是一個分布式版本管理系統，速度快，適合大規模，跨地區多人協同開。SVN是一個集中式版本管理系統。
（1）GIT生態
GIT分布式版本管理系統
Gitlab git私庫解決方案
Github git公有庫解決方案
（2）Git安裝
Centos：
yum install -y git
Ubuntu：
apt-get install git
Windows安裝git bash
Linux編譯安裝
註意不要使用git 1.8以下版本，推薦使用2.7版本
①編譯安裝git
[root@linux-node1 ~]# yum install -y epel-release
安裝依賴包：
[root@linux-node1 ~]# yum install -y curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker
[root@linux-node1 ~]# wget https://github.com/git/git/archive/v2.7.4.zip
[root@linux-node1 ~]# yum install -y unzip
[root@linux-node1 ~]# unzip git-v2.7.4.zip
[root@linux-node1 ~]# cd git-2.7.4
[root@linux-node1 git-2.7.4]# make prefix=/usr/local/git all
[root@linux-node1 git-2.7.4]# make prefix=/usr/local/git install
[root@linux-node1 git-2.7.4]# rm -rf /usr/bin/git
[root@linux-node1 git-2.7.4]# ln -s /usr/local/git/bin/git /usr/bin/git
[root@linux-node1 git-2.7.4]# git --version
git version 2.7.4
②初始化倉庫
[root@linux-node1 ~]# mkdir test
[root@linux-node1 ~]# cd test
[root@linux-node1 test]# git init #將test目錄初始化倉庫
[root@linux-node1 test]# git config --global user.name"*****"
[root@linux-node1 test]# git config --global user.email *******@qq.com
四個區域：
遠程倉庫<-->本地倉庫<-->暫存區域<-->工作目錄
四種狀態
Untracked、Unmodified、Modified、Staged
Untracked（工作目錄）-->git add -->Staged（暫存區）-->git commit版本-->Unmodified（本地倉庫）-->Edit file-->Modified-->Stage the file-->Staged
③常用命令：
git add 加入暫存
git status 查看狀態
git status -s 狀態概覽
git diff 尚未暫存的文件
git diff --staged 暫存區文件
git commit 提交更新
git reset 回滾
git rm 從版本庫中移除
git rm --cached README 從暫存區中移除
git mv 相當於mv git rm git add 三個命令
使用演示：
[root@linux-node1 test]# touch index.html ==>創建文件
[root@linux-node1 test]# vim index.html
[root@linux-node1 test]# git status ==>此時文件處於工作目錄中
位於分支 master
初始提交
未跟蹤的文件:
（使用 "git add <文件>..." 以包含要提交的內容）
index.html
提交為空，但是存在尚未跟蹤的文件（使用 "git add" 建立跟蹤）
[root@linux-node1 test]# git add index.html ==>加入代碼庫
[root@linux-node1 test]# git status ==>此時文件處於暫存區
位於分支 master
初始提交
要提交的變更：
（使用 "git rm --cached <文件>..." 以取消暫存）
新文件： index.html
[root@linux-node1 test]# git commit -m "first commit" ==>提交到本地倉庫
[master（根提交） c6bc04f] first commit
1 file changed, 3 insertions(+)
create mode 100644 index.html
[root@linux-node1 test]# git status
位於分支 master
無文件要提交，幹凈的工作區
[root@linux-node1 test]# git log
commit c6bc04f90d4ef442e2c4d5bc788b21de239332da ==>回滾需要的id

建分支,開發新功能是不能在master分支上開發
[root@linux-node1 test]# git branch about #創建分支
[root@linux-node1 test]# git status
On branch master
nothing to commit, working directory clean
[root@linux-node1 test]# git checkout about #切換分支
Switched to branch 'about'
[root@linux-node1 test]# git status
On branch about
nothing to commit, working directory clean
[root@linux-node1 test]# git log #創建的分支是在master分支當前的狀態進行創建的。所以在about分支上也會有master的記錄

git branch --no-merged查看哪些分支未被合並
git branch -d testling刪除分支
git checkout切換分支
