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 gcc perl-ExtUtils-MakeMaker
2.删除已有的git
# yum remove git
3.下载git源码
# cd /usr/src # wget https://www.kernel.org/pub/software/scm/git/git-2.0.5.tar.gz # tar xzf git-2.0.5.tar.gz
4.编译安装
# cd git-2.0.5 # 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
