Enabling Automatic Updates on RPM Distributions

CentOS and RHEL

For CentOS and RHEL the yum-cron package is the preferred approach:

yum install yum-cron

In /etc/yum/yum-cron.conf set:

download_updates = yes
apply_updates = yes

Enable and start automatic updates via:

systemctl start yum-cron.service

openSUSE

First, you need to install the automatic update package

zypper install  yast2-online-update-configuration

Then start the configuration tool (ncurses based) with:

yast2 online_update_configuration

Enable the following settings:

• Automatic Online Update
• Interval: Daily
• Skip Interactive Patches
• Agree with Licenses
• Use delta rpms

Confirm your configuration with OK.

The official openSUSE documentation can be found here
