Git学习01：Git安装
Linux Centos7 安装
一、yum安装，只要执行 yum -y install git 即可，但是yum安装无法控制版本，可能版本会比较老，推荐使用方法二
[root@ecs-x-large-2-linux-20200229160057 ~]# yum -y install git Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile ...... Installed: git.x86_64 0:1.8.3.1-21.el7_7 Dependency Installed: perl-Error.noarch 1:0.17020-2.el7 perl-Git.noarch 0:1.8.3.1-21.el7_7 perl-TermReadKey.x86_64 0:2.30-20.el7 rsync.x86_64 0:3.1.2-6.el7_6.1 Complete! [root@ecs-x-large-2-linux-20200229160057 ~]# git --version git version 1.8.3.1
二、从GitHub上下载最新的源码编译后安装
1- 去Gitbub下载安装包XXX.tar.gz文件，并上传到Linux服务器/usr目录下
2- 解压压缩包，并进入到解压后的文件夹
[root@ecs-x-large-2-linux-20200229160057 git-2.26.0]# cd /usr [root@ecs-x-large-2-linux-20200229160057 git-2.26.0]# tar -zxvf git-2.26.0.tar.gz ...... [root@ecs-x-large-2-linux-20200229160057 git-2.26.0]# cd git-2.26.0 /usr/git-2.26.0
3- 安装编译所需要的依赖(安装依赖是会自动使用yum下载git，这里需要手动删除)
[root@ecs-x-large-2-linux-20200229160057 ~]# yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker [root@ecs-x-large-2-linux-20200229160057 ~]# git --version git version 1.8.3.1 [root@ecs-x-large-2-linux-20200229160057 ~]# yum -y remove git [root@ecs-x-large-2-linux-20200229160057 ~]# git --version -bash: /usr/bin/git: No such file or directory
4-编译git源码，并安装git至/usr/local/git路径
[root@ecs-x-large-2-linux-20200229160057 ~]# cd /usr/git-2.26.0 [root@ecs-x-large-2-linux-20200229160057 git-2.26.0]# make prefix=/usr/local/git all ...... [root@ecs-x-large-2-linux-20200229160057 git-2.26.0]# make prefix=/usr/local/git install ......
5-配置环境变量，并刷新
[root@ecs-x-large-2-linux-20200229160057 git-2.26.0]# vi /etc/profile ##在文件尾部追加 export PATH=$PATH:/usr/local/git/bin #刷新环境变量 [root@ecs-x-large-2-linux-20200229160057 git-2.26.0]# source /etc/profile
6-查看Git是否安装完成
[root@ecs-x-large-2-linux-20200229160057 git-2.26.0]# git --version
git version 2.26.0
END
