The Yellowdog Updater Modified (YUM) is an rpm package management opensource tool which is available for Redhat Linux and other Linux flavors.In earlier days, its very difficult to install packages in Linux systems since it will ask for many dependencies.After yum introduction,its become very simple and yum has algorithm to select all the dependencies automatically once you configured the yum repository.
After reading this article you will get fair idea about installing yum packages,configuring yum repository and installing new packages using yum repo.

Step:1
Install yum packages from Redhat Linux OS DVD.
# rpm -i deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm
# rpm -i python-deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm
# rpm -i createrepo-0.9.8-4.el6.noarch.rpm
Step:2
Configuring Yum repository.
1.Create the Directories:
mkdir -pv /home/repo/yum
2. Copy the RPMs from the CDs/DVD to /home/repo/yum
3.Create the base repository headers:
createrepo -v /home/repo/yum
4.Go to /etc/yum.repos.d and create file with any name
(i.e repo would be fine with .repo extension)
[root@localhost yum.repos.d]# cat myyum.repo
[local-installation]
name=yum-local
baseurl=file:///home/repo/yum
enabled=1
gpgcheck=0
That’s all.We have successfully created the yum repository .
YUM configuration files
/etc/yum.conf
/etc/yum/repos.d/
/etc/yum/pluginconf.d/
/var/cache/yum/
Step:3.
Testing our work:1
[root@mylinz ~]# yum clean all

Now you can see yum commands started working and you can list available packages using the above command.
Step:4
To find packages in yum,here i just searching for vnc server package.
