　　然后按照下面的链接来处理
　　3.https://www.howtoforge.com/how-to-install-the-latest-git-version-on-centos
　　1)切换到src目录下
　　cd /usr/src
　　2)获取git的源代码
　　wget https://www.kernel.org/pub/software/scm/git/git-2.0.1.tar.gz
　　3)解压
　　tar xzf git-2.0.1.tar.gz
　　The latest Git version at this time is 2.0.1. To find the latest available version when you follow this guide,
　　go to this URL https://www.kernel.org/pub/software/scm/git/ and search for the git-VERSION.tar.gz with the highest version number.
