将Centos6.5上的git更新到2.12.0，方法如下：
1.安装编译git时需要的包
# yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
# yum install
2.删除已有的git
# yum remove git
3.下载git源码
# wget https://www.kernel.org/pub/software/scm/git/git-2.12.0.tar.gz
# tar xzf git-2.12.0.tar.gz
4.编译安装
# cd git-2.12.0 # make prefix=/usr/local/git all # make prefix=/usr/local/git install # echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc # source /etc/bashrc 5.检查一下版本号 # git --version
