As of this writing, CentOS 6.3 has a default git version of 1.7.1-2. This version is what you will have installed if you run the typical install command:
# yum install git
However, GitHub and many other services require git version 1.7.10 or higher. It turns out there is a very easy way to get git. You need to do this from a privileged account, but then the process is simple.
Add RPM Forge to Yum Repos
# wget 'http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm' # rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt # rpm -i 'http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm' # yum clean all
Install New Version from RPM Forge
# cd /etc/yum.repos.d
# vim (or whatever) rpmforge.repo
change the enabled=0 flag to enabled=1 in the section labelled [rpmforge-extras].
# yum update
# yum provides git
This will return a longer list of available git modules.
Install the newer git by copying the FULL REPO NAME. For example:
# yum install git-188.8.131.52-1.el6.rfx.x86_64
# git --version
You should have the new release installed.
Now go back and edit rpmforge.repo and disable the rpmforge-extras repository. Then ensure the yum directory is cleaned up.
# yum update
