1.卸载Centos自带的git1.7.1: yum remove git

2.    下载git2.2.1并将git添加到环境变量中

># wget https://github.com/git/git/archive/v2.2.1.tar.gz ># tar zxvf v2.2.1.tar.gz ># cd git-2.2.1 ># make configure ># ./configure --prefix=/usr/local/git --with-iconv=/usr/local/libiconv ># make all doc (有可能缺少lib:yum install zlib-devel asiidoc xmlto curl-devel) ># make install install-doc install-html ># echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc ># source /etc/bashrc

3.查看版本号

># git --version
