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?

Redhat Linux yum grouplist and groupinstall Option Not Working

in Categories , , , , last updated March 5, 2009

I‘m trying to install all the default packages by group using ‘yum groupinstall groupname‘ command under RHEL v5.x. But, grouplist, groupinstall, and groupdelete options are not working with yum. How do I fix this issue and make sure yum command works with software groups under Redhat Enterprise Linux to increase my productivity?
