These are the Terminal commands I recently used (September 2019) to install Git 2.23.0 from source on RHEL 7.x. I ran this in a VirtualBox VM after a fresh install from the ISO.
You mileage will vary as the yum packages are updated over time. The yum install
line below should include all the dependencies, at least it did for me. Depending upon how often you use yum update
you may need to run yum --enablerepo=base clean metadata
as su
before you run the following commands.
cd ~/Downloads
su
# First remove old system git
yum erase git
