三. 重复步骤一，验证是否安装成功
[root@localhost ~]# git --version
git version 1.8.3.1
四. yum -y upgrade git 升级（发现安装git版本过低，发现升级无效）
[root@localhost ~]# yum -y upgrade git

六. 现在又要重新安装git了
在Git的官网上，对Red Hat Linux安装git建议有两种方法
1、下载源代码、编译、构建、配置环境变量
2、第三方仓库IUS
本文采用IUS第三方仓库安装的方式。第一种方式自行google
这里是ius官方的安装说明及使用说明
IUS安装2.x

curl https://setup.ius.io | sh安装使用说明里面自动化安装脚本
