tar -zxf git-2.24.0.tar.gz
cd git-2.24.0
make prefix=/usr/local/git all
make prefix=/usr/local/git install
添加环境变量
vim /etc/profile
export PATH=$PATH:/usr/local/git/bin

centos默认的的yum仓库中的默认版本很低，有时我们需要安装高版本git，编译安装又太麻烦。
下面介绍一种yum安装高版本git的方法

1，安装 WANDisco 仓库包

安装 centos6 WANDisco 仓库
yum install http://opensource.wandisco.com/centos/6/git/x86_64/wandisco-git-release-6-1.noarch.rpm

安装 centos7 WANDisco 仓库
yum install http://opensource.wandisco.com/centos/7/git/x86_64/wandisco-git-release-7-2.noarch.rpm

2，安装 Git
yum -y install git
3，版本验证
git version
centos7 安装快捷复制
yum install http://opensource.wandisco.com/centos/7/git/x86_64/wandisco-git-release-7-2.noarch.rpm
yum -y install git
git version

yum install nss
