To send package update notifications via email on a Red Hat/CentOS/Fedora system, you can use the yum-cron package, which is part of the yum-utils package.
Here’s how to set up yum-cron to send email notifications:
- Install the
yum-cronpackage:
sudo yum install yum-cron
- Open the
/etc/yum/yum-cron.conffile for editing:
sudo vi /etc/yum/yum-cron.conf
- Change the following parameters in the configuration file:
update_messages = yes
email_from = root.com
email_to = user.com
Set update_messages to “yes” to enable update notifications. Replace root@example.com with the email address that the notification will be sent from, and replace user@example.com with the email address that the notification will be sent to.
- Save and exit the file.
- Start the
yum-cronservice:
sudo systemctl start yum-cron
Now, when updates are available for installation, yum-cron will send an email notification to the configured email address.
