How to use yum-cron to automatically update RHEL/CentOS Linux

Posted on in Categories , , , , , last updated February 2, 2018

The yum command line tool is used to install and update software packages under RHEL / CentOS Linux server. I know how to apply updates using yum update command line, but I would like to use cron to update packages where appropriate manually. How do I configure yum to install software patches/updates automatically with cron?
