I would like to make a local yum Repository which only contains rpm packages I need.Copy packages from the CentOS DVD？That can’t resolve dependency problems between packages.We can use yumdownloader to download packages.
1、create directory to store packages
#mkdir /media/CentOS
2、install yum-utils which provides yumdownloader
#yum -y install yum-utils
3、download packages,–reolve option will resolve dependencies and download required packages
#cd /media/CentOS
#yumdownloader –resolve rsync telnet vixie-cron
