CentOS中yum里沒有Git，需要手動安裝。
 
首先需要安裝git的依賴包

yum install curl
 yum install curl-devel
 yum install zlib-devel
 yum install openssl-devel
 yum install perl
 yum install cpio
 yum install expat-devel
 yum install gettext-devel
 
下載最新的git包
 

wget http://www.codemonkey.org.uk/projects/git-snapshots/git/git-latest.tar.gz
 tar xzvf git-latest.tar.gz
 cd git-xxxx-xx-xx
 autoconf
 ./configure
 make | make install
 
驗證是否安裝成功：檢查安裝的版本
 

git –version
