Linux安装git

新建存放git压缩包目录
mkdir -p /usr/local/git

下载git压缩包
wget https://github.com/git/git/archive/v2.17.0.tar.gz

解压缩
tar -zxvf v2.17.0.tar.gz

安装编译源码所需依赖
yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker

安装依赖时，yum自动安装了Git，需要卸载旧版本Git
yum remove git

进入解压后的文件夹执行编译
make prefix=/usr/local/git all

安装Git至/usr/local/git路径
make prefix=/usr/local/git install

配置环境变量
vim /etc/profile

export PATH=$PATH:/usr/local/git/bin

刷新环境变量文件
source /etc/profile

验证
git --version
