    因爲centos中的源倉庫中git不是最新版本，須要進行源碼安裝。

一、查看yum倉庫git信息

[root@iZm5e3d4r5i5ml889vh6esZ zh]# yum info git

二、依賴倉庫安裝

[root@iZm5e3d4r5i5ml889vh6esZ zh]# yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
[root@iZm5e3d4r5i5ml889vh6esZ zh]# yum install  gcc perl-ExtUtils-MakeMaker

三、卸載已安裝的git

[root@iZm5e3d4r5i5ml889vh6esZ zh]# yum remove git

四、下載git最新源碼

    下載地址：https://github.com/git/git/releases

wget https://github.com/git/git/archive/v2.17.1.tar.gz

五、安裝

    解壓、安裝

[root@iZm5e3d4r5i5ml889vh6esZ git]# tar zxvf v2.17.1.tar.gz 
[root@iZm5e3d4r5i5ml889vh6esZ git]# cd git-2.17.1/
[root@iZm5e3d4r5i5ml889vh6esZ git]# make prefix=/usr/local/git all
[root@iZm5e3d4r5i5ml889vh6esZ git]# make prefix=/usr/local/git install

六、添加到環境變量

[root@iZm5e3d4r5i5ml889vh6esZ git]# vim /etc/profile
export GIT_HOME=/usr/local/git

export PATH=$GIT_HOME/bin:$PATH
[root@iZm5e3d4r5i5ml889vh6esZ git]# source /etc/profile

七、查看當前版本號

[root@iZm5e3d4r5i5ml889vh6esZ git]# git --version
git version 2.17.1
