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。

1. 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

2. 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

3. Verify that the key was installed successfully:

rpm -qa gpg*

4. Verify that the EPEL and PUIAS Computational repositories are enabled:

yum repolist

5. Install Git 1.8

yum --enablerepo=PUIAS_6_computational install git

Note: I am not quite happy with this solution, as it only netted me Git 1.8.3 however I do not have the time to find a better solution right now.
