CentOS / RHEL Configure Yum Automatic Update Retrieval and Installation

Posted on in Categories , , , , , , last updated May 18, 2009

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’d like to use cron to manually update packages where appropriate. How do I configure yum to install software patches / updates automatically with cron?
