安装Git
$sudo apt-get install git$sudo apt-get install git-core
更新Git
$git clone git://git.kernel.org/pub/scm/git/git.git
安装好git后在终端输入git 命令会显示git命令提示，证明git已经安装成功。
初始化代码仓库
$mkdir Android4.2$cd android4.2$git init
提示： Initialized empty Git repository in /data/Downloads/Git/android4.2/.git/证明git仓库（repository）创建成功 配置config文件（全局）
$cd .git$vim config
该配置文件的原始内容为：
[core] repositoryformatversion = 0 filemode = true bare = false logallrefupdates = true
在该配置文件中加入以下内容：
[receive]denyCurrentBranch = ignore
加入该配置的目的是：允许使用git push 提交代码到服务器，否则会出现以下异常：
加入该配置的目的是：允许使用git push 提交代码到服务器，否则会出现以下异常：remote: error: refusing to update checked out branch: refs/heads/masterremote: error: By default, updating the current branch in a non-bare repositoryremote: error: is denied, because it will make the index and work tree inconsistentremote: error: with what you pushed, and will require ‘git reset –hard’ to matchremote: error: the work tree to HEAD.remote: error:remote: error: You can set ‘receive.denyCurrentBranch’ configuration variable toremote: error: ‘ignore’ or ‘warn’ in the remote repository to allow pushing intoremote: error: its current branch; however, this is not recommended unless youremote: error: arranged to update its work tree to match what you pushed in someremote: error: other way.remote: error:remote: error: To squelch this message and still keep the default behaviour, setremote: error: ‘receive.denyCurrentBranch’ configuration variable to ‘refuse’.To git@192.168.1.X:/var/git.server/…/web!

在代码仓库创建一个说明文档（该文档可以随便创建）
$touch spec.txt
备注：如果初始的代码仓库为空，git push origin master提交代码的时候会出现以下异常：
error: src refspec master does not match any.error: failed to push some refs to ‘/data/Downloads/Git/android4.2/.git因此我们需要在初始化代码仓库之后，，在仓库中创建一个文件：
实例：
$touch spec.txt$git add spec.txt$git commit-a -m “first commit”$git push
此时，基本的代码仓库已经创建完成。本地代码仓库的Git库为：/data/Downloads/Git/android4.2/.git
去追寻那飞翔的翅膀。落叶随风淡定了它漂泊的方向。
