安裝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
安裝好git後在終端輸入git 命令會顯示git命令提示，證明git已經安裝成功。
初始化代碼倉庫
$mkdir Android4.2
$cd android4.2
$git init
提示： Initialized empty Git repository in /data/Downloads/Git/android4.2/.git/證明git倉庫（repository）創建成功
配置config文件（全局）
$cd .git
$vim config
該配置文件的原始內容為：
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
在該配置文件中加入以下內容：
[receive]
denyCurrentBranch = ignore
加入該配置的目的是：允許使用git push 提交代碼到服務器，否則會出現以下異常：
加入該配置的目的是：允許使用git push 提交代碼到服務器，否則會出現以下異常：
remote: error: refusing to update checked out branch: refs/heads/master
remote: error: By default, updating the current branch in a non-bare repository
remote: error: is denied, because it will make the index and work tree inconsistent
remote: error: with what you pushed, and will require 'git reset --hard' to match
remote: error: the work tree to HEAD.
remote: error:
remote: error: You can set 'receive.denyCurrentBranch' configuration variable to
remote: error: 'ignore' or 'warn' in the remote repository to allow pushing into
remote: error: its current branch; however, this is not recommended unless you
remote: error: arranged to update its work tree to match what you pushed in some
remote: error: other way.
remote: error:
remote: error: To squelch this message and still keep the default behaviour, set
remote: error: 'receive.denyCurrentBranch' configuration variable to 'refuse'.
To [email protected]:/var/git.server/.../web
! [remote rejected] master -> master (branch is currently checked out)
error: failed to push some refs to '[email protected]:/var/git.server/.../web'
在代碼倉庫創建一個說明文檔（該文檔可以隨便創建）
$touch spec.txt
備注：如果初始的代碼倉庫為空，git push origin master提交代碼的時候會出現以下異常：
error: src refspec master does not match any.
error: failed to push some refs to '/data/Downloads/Git/android4.2/.git
因此我們需要在初始化代碼倉庫之後，在倉庫中創建一個文件：
實例：
$touch spec.txt
$git add spec.txt
$git commit-a -m "first commit"
$git push
此時，基本的代碼倉庫已經創建完成。本地代碼倉庫的Git庫為：/data/Downloads/Git/android4.2/.git
