git 源码安装

1. 从官网获取版本https://git-scm.com/download/linux

cd /usr/local/src/
https://www.kernel.org/pub/software/scm/git/git-2.38.1.tar.gz```

2.  解压 tar
  tar -zxvf  git-2.38.1.tar.gz

3. 3安装编译所需依赖，命令为：

yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker

4. 安装依赖时，yum自动安装了Git，需要卸载旧版本Git，命令为： 

yum remove git

5.  cd git-2.38.1
make prefix=/usr/local/git all 
make prefix=/usr/local/git install

6. 打开环境变量配置文件，命令 

vim /etc/profile 
在底部加上Git相关配置信息：

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