linux 升级git

Ubuntu升级安装git

# 仓库版本的安装
apt-get install git

# 最新版本的安装，for Ubuntu 
add-apt-repository ppa:git-core/ppa
apt update
apt install git

Centos7 升级安装git

yum install -y https://repo.ius.io/ius-release-el7.rpm
yum install -y epel-release 

# re-install git:
yum erase -y git*
yum install -y git-core

• 还可以尝试通过商业公司的源安装git

  # yum install http://opensource.wandisco.com/centos/6/git/x86_64/wandisco-git-release-6-1.noarch.rpm
  # yum install http://opensource.wandisco.com/centos/7/git/x86_64/wandisco-git-release-7-1.noarch.rpm
  yum install -y http://opensource.wandisco.com/centos/7/git/x86_64/wandisco-git-release-7-2.noarch.rpm
  yum makecache
  yum install -y git
  

• 当多个源中软件版本有冲突时可以指定禁用和启用那个源

  #查看源对应的版本
  yum provides git
  
  	git-1.8.3.1-23.el7_8.x86_64 : Fast Version Control System
  	源    ：base
  	git236-2.36.1-2.el7.ius.x86_64 : Fast Version Control System
  	源    ：ius
  	匹配来源：
  	提供    ：git = 2.36.1-2.el7.ius
  
  # 禁用=base,updates源,并通过ius源安装git
  yum --disablerepo=base,updates --enablerepo=ius install git
  

• 或者通过源码编译安装

#安装依赖
yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
yum install  gcc perl-ExtUtils-MakeMaker

# 删除旧版本git
yum remove git

# 下载源码
cd /usr/src
wget https://www.kernel.org/pub/software/scm/git/git-2.0.4.tar.gz
tar xzf git-2.0.4.tar.gz

# 编译安装
cd git-2.0.4
make prefix=/usr/local/git all
make prefix=/usr/local/git install

#修改环境变量
echo 'export PATH=$PATH:/usr/local/git/bin' >> /etc/bashrc
#或者这种方式修改环境变量 
echo 'export PATH=$PATH:/usr/local/git/bin' > /etc/profile.d/git.sh

source /etc/bashrc

# 验证
git --version

git version 2.0.4
