[2] The yum-autoupdate script is placed in /etc/cron.daily and it runs everyday by anacron. But it’s risks to update packages automatically without testing if you can not stop your server easily, then turn to false the auto-update setting like follows.

[root@dlp ~]# vi /etc/sysconfig/yum-autoupdate

@ line 7: change to false

ENABLED=”false”
