Can yum run automatically ?

[mha]

Good day community,
I find it difficult or maybe impractical to run yum manually evryday or let say regulary. Can I configure it to run automatically daily ? eg by means of crontab . I have no idea how to strat crontab activities, I am just a noob.

regards,

Yes, it is possible to run yum nightly, you will still have to reboot for the kernel updates.

service yum start

chkconfig --level 3 yum on

You can also do it with a nice gui: System Settings-->Server Settings-->Services.

Does this mean I have to leave the system running all night every night ? I usually shutdown the system after I finish my work; I use this machine for 1 to 3 hours daily only when I'am home.

as far as i know cron will run jobs it missed while a computer was off. I am not sure about this (my computers are always on) can someone confirm?

[foolish]

If you start the yum nightly update service and only that, it will only run at night. But there's another service called anacron that will make sure cronjobs are run, even if the computer is shut of when the cron job is executed. This means that anacron will make sure the update gets done during the time the computer is turned on.

So, in system-config-services, enable yum and anacron.

Hi, I have two Linux FC2, and I enable both yum and anacron and confirm both service are running.
But I found that 1 of the machine always doesn't update automatically, e.g kernel update. What can I check further?

Thanks.
