What are unattended updates
Unattended updates is a service within Linux that will automatically download and install updates on your Linux Machine allowing your Server to stay up to date.
How to install and configure unattended updates
From your SSH console type:
yum install yum-cron.noarch
Open the configuration file
locate the mail part of the config
# by default MAILTO is unset, so crond mails the output by itself
# example: MAILTO=root
set the mail address to an address of your choice.
Save the file and start the cron service
service yum-cron start
Enabling nightly yum update: [ OK ]
