YUM-Yellowdog Updater Modified

*Yum is RPM(Redhat Package Manager)that is able to query for information about 
i)available packages , 
ii)fetch packages from repositories, 
iii)install and uninstall them.

*You must have superuser privileges in order to use Yum to install, update or remove packages on your system.

*Packages for repository server are:
 i)delta.rpm
 ii)Python-delta.rpm
 iii)create.repo

Commands:

To check whether yum is configured or not. 
#yum repolist all.

To configure yum server you need to copy packages of your RHEL anywhere in the "/".
#cp -ra /media/OS Cd Path/* /var/ftp/pub/yum                  
   "*" Denotes everything that to be copied
   "/var/ftp/pub/yum" is the directory where i will copy my packages.

You can check your Copy Status by opening a new terminal and going to the particular directory where your yum is being copied.
#du -sh

After completion of copying ,travel to the path given below to create a repo file .
#cd /yum/yum.repos.d/
repos.d is a repository.
you will find some repo files, do not delete them .and create a new repo file bby below command.

#vim abc.repo
  you can use any editor to create a file either vim or vi.

After you enter into that file use insert tool by pressing "I", and start typing as below.

[abc]
name=abc
baseurl=file:///var/ftp/pub/yum
gpgcheck=0

:wq(save & quit)

Comments:[abc] it can be anyname.
                   baseurl its your yum path where your packages are kept.
                   gpgcheck is key based authentication.
                   0= if it is not registered with RHN.
                   1= if it is registered with RHN.
                    RHN=Redhat Network.


After completing save and quit. run the below commands.
#yum clean all
#yum update all
#yum list all or yum repolist all

yum repolist all will display your repo file with enabled comment.
easiest way to confirm that your yum is running properly.
#yum list all -- you will find all your packages will be listed in Black color texts.


Done.
