git安装：
1.下载安装包:
sudo wget http://learning.happymmall.com/git/git-v2.8.0.tar.gz
2.安装git依赖包:
sudo yum -y install zlib-devel openssl-devel cpio expat-devel gettext-devel curl-devel perl-ExtUtils-CBuilder perl-ExtUtils- MakeMaker
3.解压git压缩包后进入目录
sudo tar -zxvf git-v2.8.0.tar.gz
cd git-2.8.0/
4.sudo make prefix=/usr/local/git all
5.sudo make prefix=/user/local/git install
6.查看git：git --version(提示：command not found)
7.查看git安装到哪里了 whereis git（提示：git: /usr/local/bin/git）之前安装过了
