By default git the popular software code management software (SCM) is not installed on cPanel/WHM CentOS server before version 11.36, you may need to add in a new repository package manager which contains the compiled code and edit the /etc/yum.conf file to make it work. This guide is for those on older cPanel servers, if you are on version 11.36 and above find out where and what version of Git you have.
Locate the path to Git
which git
See the installed version
git --version
If you don't have it carry on with the tutorial...
Git being a primarily comand line driven application you need to connect to your server via shell access. First of all try and see if it is installed with yum.
Try yum
yum install git
or
yum install git-core
If you get an error about dependencies try using an exclude command which bypasses any exclusions set in /etc/yum.conf including pearl which is set to exclude by default in cPanel servers.
yum --disableexcludes=main install git
If you get an error for all of the above 'No package git available.' then you will need to add a repository that contains git.
Adding a Repository to cPanel
A very popular package manager repository for CentOS is RPMForge containing 5000 odd packages one of which is git.
For CentOS 5 find out your machine type
uname -a
Then download the RPMForge release package either i386 or x86_64
Install the DAG's GPG key which will verify and encrypt any packages that you install with this package manager
rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
Verify the package you have downloaded, (change the command at the end to reflect the machine)
rpm -K rpmforge-release-0.5.2-2.el5.rf.*.rpm
Install the RPMForge Package, (change the command at the end to reflect the machine)
rpm -i rpmforge-release-0.5.2-2.el5.rf.*.rpm
Now you should have some additional repository files in /etc/yum.repos.d/
cd /etc/yum.repos.d/ ; ls -la -rw-r--r-- 1 root root 1926 Feb 25 02:20 CentOS-Base.repo -rw-r--r-- 1 root root 631 Feb 25 02:20 CentOS-Debuginfo.repo -rw-r--r-- 1 root root 626 Feb 25 02:20 CentOS-Media.repo -rw-r--r-- 1 root root 6118 Feb 25 02:20 CentOS-Vault.repo -rw-r--r-- 1 root root 137 Jan 27 08:22 dedi.repo -rw-r--r-- 1 root root 739 Nov 12 2010 mirrors-rpmforge -rw-r--r-- 1 root root 717 Nov 12 2010 mirrors-rpmforge-extras -rw-r--r-- 1 root root 728 Nov 12 2010 mirrors-rpmforge-testing -rw-r--r-- 1 root root 1113 Nov 12 2010 rpmforge.repo
Now try and install yum, remember the dependency excludes issue though - you can also edit the /etc/yum.conf file by removing pearl* from the exclude line under [main] and then install yum - then add pearl* back in after the install to keep cPanel happy.
For CentOS 4 and 6 try these instructions for RPMForge installation.
