From a command prompt I typed:
at midnight tomorrow [ENTER]
yum -y update [ENTER]
[CTLR + D]
This set up my command to update via my Yum repositories tonight at 12:00:00am (well technically tomorrow).
That is all.
warning: locate: warning: database /var/lib/slocate/slocate.db' is more than 8 days old
warning: Please make sure the daily cron job is enabled in /etc/updatedb.conf
The quick way to fix this error is to run locate -u from the command line as root.
Then edit the locate config file (vi /etc/updatedb.conf) and change the line "DAILY_UPDATE=no" to "DAILY_UPDATE=yes"
