首先通过git --version命令查看系统版本,我的是1.7.1 1.卸载老版本git
yum remove git2.下载git2.2.1并添加到环境变量中
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
make install install-doc install-html
echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc
source /etc/bashrc查看版本号
git --version
