Yum is Server in Linux Os and
It is use to store all the packages of Linux which we call Rpm Rpm stand for (Red hat package manager) for future installation. and there will be no reuse of any
linux media like Dvd etc. and Most Important Is this that yum install every packages dependency at once
dependency:
In Linux every package have alot of dependencies as a example if you want
to Install dhcp it have more dependency to Install one by one through
#rpm -ivh command it will take lot of time
Therefor we use Yum Server.
NOTE:
Yum Server is very important and very intresting to Configure
Requirment for Installation

Step 2
Mount your DvD in any Directory but probably we mount it in /Media use this easy command
#mount /dev/dvd /media
Then Enter to /media
#cd /media
you will be see your mount data Now you just need to install one package for /ftp/pub location it is
#rpm -ivh Server/vsftpd-2.0.5-10.e15.i386.rpm
This will install vsftpd for ftp/pub and you can easly enter to that location Note whenever you enter any command just write firt few words then press tab it will show that exact complet comand then select that wait for more .............
