Linux下更新Git

 查看git版本，卸载旧版本（如果没有安装git请直接到下一步）

git --version
yum remove git

 安装依赖软件

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

 编译安装最新的git版本

cd /usr/local/src/
wget -O git.zip https://github.com/git/git/archive/master.zip
unzip git.zip
cd git-master
make prefix=/usr/local/git all
make prefix=/usr/local/git install

 添加到环境变量

echo "export PATH=$PATH:/usr/local/git/bin" >> ~/.bashrc
source ~/.bashrc
git --version

 最新的git就装好了
