一、使用yum安装Git
1.查看 yum 源仓库的 Git 信息
使用yum info git查看
[root@localhost~]# yum info git
Loaded plugins: fastestmirror, langpacks
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast
Determining fastest mirrors
Available Packages
Name : git
Arch : x86_64
Version : 1.8.3.1
Release : 23.1.al7
Size : 4.4 M
Repo : updates/2.1903/x86_64
Summary : Fast Version Control System
URL : http://git-scm.com/
License : GPLv2
Description : Git is a fast, scalable, distributed revision control system with an
: unusually rich command set that provides both high-level operations
: and full access to internals.
:
: The git rpm installs the core tools with minimal dependencies. To
: install all git packages, including tools for integrating with other
: SCMs, install the git-all meta-package.
yum源中的git版本比较老1.8.3.1,如果你依旧想安装他，继续执行下边操作。
2. 安装Git
yum install git
3.查看git版本
[root@localhost ~]# git --version
git version 1.8.3.1
4.卸载git
yum remove git
二、源码包安装Git
1.下载源码包
git源码包官方下载地址
https://mirrors.edge.kernel.org/pub/software/scm/git/
我下载的是git-2.39.0.tar.gz,下载目录放在了/usr/local
wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.39.0.tar.gz
2.解压源码包
tar -zxvf git-2.39.0.tar.gz
3.安装需要的依赖
# 安装依赖
yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker
4.检查是否安装过git
如果已经安装编译源码所需依赖的时候，yum自动帮你安装了git，这时候你需要先卸载这个旧版的git
yum -y remove git
5.编译安装
我选择安装在/usr/local/git目录下
cd /usr/local
mkdir git
# 进入文件目录
cd git-2.39.0
# 编译
make prefix=/usr/local/git all
# 安装git至/usr/local/git路径
make prefix=/usr/local/git install
6.配置环境变量
vim /etc/profile
# 按i进入编辑模式，增加下方代码
export PATH=$PATH:/usr/local/git/bin
# 增加后按esc退出编辑模式，输入:wq保存退出
# 使配置文件生效
source /etc/profile
7.查看git是版本
[root@localhost ~]# git --version
git version 2.39.0
