centos7 安裝Git
Git 的工作需要調用 curl，zlib，openssl，expat，libiconv 等庫的代碼，所以需要先安裝這些依賴工具。
yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
yum install gcc perl-ExtUtils-MakeMaker

wget https://www.kernel.org/pub/software/scm/git/git-2.16.3.tar.gz
編譯並安裝：
tar -zxf git-2.16.3.tar.gz
cd git-2.16.3.tar.gz
make prefix=/usr/local all
sudo make prefix=/usr/local install
加入環境變量
echo “export PATH=$PATH:/usr/git/bin” >> /etc/profile
source /etc/profile
