源引：centos6.5 安装git
1.安装编译git时需要的包
# yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
# yum install gcc perl-ExtUtils-MakeMaker
2.删除已有的git
# yum remove git
3.下载git源码，我自己下载的是2.0.0版本的下载地址：
http://pan.baidu.com/s/1qXFnOxI
# cd /usr/local
# wget https://www.kernel.org/pub/software/scm/git/git-2.0.5.tar.gz
# tar xzf git-2.0.5.tar.gz
4.编译安装
# pwd ## /usr/local
# cd git-2.0.5
# make prefix=/usr/local/git-2.0.5 all
# make prefix=/usr/local/git-2.0.5 install
//配置环境变量，按照你喜欢的方式来。
# echo "export PATH=$PATH:/usr/local/git-2.0.5" >> /etc/bashrc
# source /etc/bashrc
5.检查一下版本号
# git --version
