1.首先查看下当前的版本

[root@localhost ~]# git --version

git version 1.8.2.1

 

2.尝试进行升级

[root@localhost ~]# yum update git

吐槽下，先尝试处理下，发现升级失败。

首先要卸载掉之前安装的git ， yum  remove git

然后按照下面的链接来处理

 

3.

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  and search for the git-VERSION.tar.gz with the highest version number.

 

ps：2015年10月18日看到的最新版本是2.6.2
