^^ that's a little different since Ubuntu is a different OS, if you want a specific RHEL solution, have you enabled subscription-manager? – Nihhi

Did not use subscription-manager. What is the process for it? Does CentoOS has as well? – Conjunct

CentOS does not use subscription-manager. Configuration of RPM channels varies quite a bit between CentOS and Red Hat Enterprise Linux, so which is it? – Haematin

Currently I have a need or Rhel server.. but there are few other servers that are CentOS that also need the same python upgrade.. – Conjunct

Answer 1

Sharing what worked for me. Worked for me on Enterprise RHEL 7.

#-> python --version
Python 2.7.5

#-> yum install rh-python38

#-> scl enable rh-python38 bash

#-> python --version
Python 3.8.0

But you will have enter into the scl shell everytime as the default shell would still be Python 2.7. To make this permanent, I had to

Add this to my ~/.bash_profile

source /opt/rh/rh-python38/enable
