Installing Git 2 on CentOS 7
Git-ing a bit stale?
RHEL/CentOS 7 is starting to feel a somewhat dated, but it still has over 2½ years before it reaches the end of its support lifetime that Red Hat has set for the end of June 2024.
One component that is far enough outdated to cause serious annoyance is Git.
Git is by far the most-used version control system in the world. It popularized the distributed model of tracking changes to source code files and greatly simplified collaboration by multiple developers. It is open source and free software and is used by most public and many internal software projects, and also by solo developers. IDEs such as VS Code and IntelliJ idea integrate with it. SaaS code hosting providers GitHub, GitLab, Bitbucket, and others are built around it. We have been using and advocating Git since 2007 — see our blog posts about Git for a variety of helpful articles.
CentOS/RHEL 7 includes Git version 1.8.3, which was released in May 2013. There have been 2 major, 36 minor, and 216 patch releases of Git in the 8½ years between then and the current version 2.34.1!
The makers of CentOS/RHEL have good reasons to stick with versions they shipped with for the lifetime of the operating system: compatibility, stability, predictability. They only want to release updates that are entirely compatible, mostly for bugfixes and security updates.
Using a newer version will likely have some differences, but for software primarily used interactively by humans who can adapt to change, this is often worth the tradeoff of more features vs. occasional unexpected change.
We help you freshen up
To relieve the pain of aging software, we here at End Point Dev package up newer Git versions for RHEL 7 as needed for ourselves and our clients. You can use it too! Our current packaged version as of today is the latest Git, version 2.34.1, which was released on 24 November 2021.
Why not just build the latest version from source? That works well on a single developer workstation if you don’t mind staying abreast of each new Git release on your own, and doing a bit of work to build them.
We recommend using packages specific to your OS because it is faster, easier, and fits well with automation tools such as Ansible, Salt, Chef, and Puppet. And when you configure a Yum repository that includes ongoing package updates, the updates are automatically applied to all your systems as part of your routine OS maintenance.
Here are instructions showing how you can install the latest Git package we built, on CentOS/RHEL 7 systems.
Check your version of git
First, see what version you have installed:
$ git --version git version 220.127.116.11
Now see where it is installed:
$ which git /usr/bin/git
If you have
git installed somewhere else, such as
/usr/local/bin/git, it was probably built from source and installed there, and you should consider deleting that other installation before you install this new packaged one.
To make sure it was installed from an RPM using yum:
$ rpm -qi git Name : git Version : 18.104.22.168 Release : 23.el7_8 Source RPM : git-22.214.171.124-23.el7_8.src.rpm Build Date : Thu 28 May 2020 08:37:56 PM UTC Build Host : x86-02.bsys.centos.org Packager : CentOS BuildSystem <http://bugs.centos.org> Vendor : CentOS
(I omitted a few uninteresting lines from that output so we can focus on the essentials.)
If instead of the above you see this from
rpm and/or don’t have
git installed at all:
$ rpm -qi git package git is not installed $ which git /usr/bin/which: no git in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
That’s fine. In that case you will just be installing Git on this system for the first time.
Add the End Point Yum repository
Now install the End Point package repository Yum repo package:
$ sudo yum install https://packages.endpointdev.com/rhel/7/os/x86_64/endpoint-repo.x86_64.rpm
That adds two important files to your system:
Yum repo config file
The first is
/etc/yum.repos.d/endpoint.repo which is configuration for
yum, an extension to its main
/etc/yum.conf configuration file. Here is where we point your Yum setup to our packages.endpointdev.com repository to look for packages in the future.
The second is
/etc/pki/rpm-gpg/RPM-GPG-KEY-endpoint-7 which is the PGP/GnuPG public key matching the secret key we use to sign packages in our repository, so your
yum can verify the packages have not been corrupted, either accidentally during transmission, or intentionally by Bad Folks.
Install or upgrade git
Now installing or upgrading to the new version of Git is as simple as:
$ sudo yum install git
You can use
yum upgrade git if you already have it installed, but
yum install git works in either case.
You should see output similar to this:

If you don’t see the new
git version available, you may need to clear your Yum caches with:
$ sudo yum clean all
In the install/upgrade output above from
yum, notice the question: “Is this ok”? As long as what you see is similar to the above, everything should be fine. But investigate further before proceeding if it proposed any unexpected package upgrades or removals.
If you agree to continue, you’ll see something like:

Now check again which version of
git is installed, and what the RPM database contains:
$ git --version git version 2.34.1 $ rpm -qi git Name : git Version : 2.34.1 Release : 1.ep7 Architecture: x86_64 Source RPM : git-2.34.1-1.ep7.src.rpm Build Date : Thu 09 Dec 2021 01:15:52 AM UTC Build Host : rhel7-build64.epinfra.net Packager : End Point Hosting Team <firstname.lastname@example.org> Vendor : End Point Dev - https://packages.endpointdev.com/
(Again I removed a few uninteresting lines.)
We can see that this new version came from the End Point repository and is very fresh as of the time of this writing.
Bonus: Newer tmux!
You may also be interested in our much newer tmux 3.2a vs. the tmux 1.8 that comes with CentOS 7.
If you want it, now that you have the End Point Yum repository configured, you can simply do:
$ sudo yum install tmux
- End Point package repositories
- pkgs.org makes it easy to find RPM packages across the various Linux distros, architectures, and repositories. We often use it to find source RPMs from Fedora Rawhide and other distros that we can rebuild for RHEL.

- GitHub blog Highlights from Git 2.34 is a good exploration of important changes in the most recent version of Git. GitHub’s articles about each Git release are worth reading.
