我的Linux安装的是Centos6.4，昨天在系统里使用yum安装了git，可是在往git@osc上push代码的时候，报出了错误，社区里有人说需要升级git到1.8.3版本以上，于是就搜索到了这么一个方法，挺好用的，我在这里mark一下，以便以后用到的时候拿出来，嘿嘿。
- Download PUIAS repo:
wget -O /etc/yum.repos.d/PUIAS_6_computational.repo https://gitlab.com/gitlab-org/gitlab-recipes/raw/master/install/centos/PUIAS_6_computational.repo - Next download and install the GPG key:
wget -O /etc/pki/rpm-gpg/RPM-GPG-KEY-puias http://springdale.math.ias.edu/data/puias/6/x86_64/os/RPM-GPG-KEY-puias && rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-puias - Verify that the key was installed successfully:
rpm -qa gpg* - Verify that the EPEL and PUIAS Computational repositories are enabled:
yum repolist - Install Git 1.8
yum --enablerepo=PUIAS_6_computational install git
