1、安装所需软件包
yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
yum install gcc perl-ExtUtils-MakeMaker
2、下载&安装
cd /tmp
wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.22.0.tar.gz
tar xzf git-2.22.0.tar.gz
cd git-2.22.0
make prefix=/usr/local/git all
make prefix=/usr/local/git install
echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc
source /etc/bashrc
3、检查版本
git --version
o、其他
centos 7.x版本自带git 1.8，安装新版本之前需要使用yun remove git卸载（安装后卸载也可以）。
