ACKNOWLEDGEMENT

It is my great pleasure to express my profound gratitude to our trainer Dr. Anil

Singh for suggesting us the topic of the project, and also providing us with the

invaluable suggestions and guidance throughout the project work.

I would also like to express our sincere thanks to HPES faculty, friends, parents

and God for their priceless support.

Thankfully,

Nupur Agarwal

INSTALLING PACKAGES IN LINUX

VIA YUM SERVER

ABOUT THE YUM SERVER

The Yellowdog Updater,Modified(YUM) is an open source command-line package-

management utility for RPM-compatible Linux operating systems and has been released under the

GNU General Public License. It was developed by Seth Vidal and a group of volunteer

programmers.Though yum has a command-line interface,several other tools provide graphical user

interfaces to yum functionality.

WHY USE YUM?

The Yellowdog Updater,Modified YUM is an automatic updater and package

installer/remover for rpm- based systems. It automatically computes dependencies and figures out

what things should occur in order to safely install, remove and update rpm packages. Yum also

efficiently and easily retrieves information on any package installed or available in a repository to

the installer. Yum makes it easier to maintain groups of machines without having to manually update

each one using rpm or other tools. Yum can manage package groups, manage package groups,

multiple repositories, fallback repositories and more to permit centralized package management

performed by just one or two individuals to scale over an entire organization.

Other features of the YUM package manager include:

Simple interface. Multiple repositories. Simpleconfig file. Fast operation. RPM-consistent behavior. comps.xml group support, including multiple repository groups.

ADVANTAGES OF USING YUM SERVER

Automatic resolution of software dependencies

If a package installation or upgrade request is made and requires the installation or upgrade of

additional packages, YUM can list these dependencies and prompt the user to install or upgrade

them.

Command-line and graphical versions

The command-line version can be run on a system with a minimal number of software packages. The

graphical versions offer ease-of-use and a user-friendly graphical interface to software management.

Multiple software locations at one time

YUM can be configured to look for software packages in more than one location at a time.

Ability to specify particular software versions or architectures

Software locations accessible by YUM can contain multiple versions of the same RPM package and

different builds for different architectures such as one for i686 and one for x86_64. yum can easily

check the appropriate version and download it.

INSTALLING YUM SERVER

To create a YUM server in Linux

Step 1:- Create a directory named repo mkdir /repo

Mount it to any disk which have more space as comparison to root mount /dev/sda5

/repo

Step 2 :-Insert DVD of Rhel-5 and Mount CD ROM mount /dev/cdrom /mnt

Step 3 :-Copy directoryServer, Cluster, ClusterStorage, VT from DVD/CD of Rhel-5 cp RvfServer ClusterStorage Cluster VT /repo


10/17

Copy Server

Copy ClusterStorage And Cluster

Copy VT


11/17

Step 4 :- Delete repodata named directory from all the four directories in /repo i.e., Server,

ClusterStorage, Cluster, and VT

(a)rmrf Serverrepodata

(b)rmrf Cluster/repodata

(c)rmrf ClusterStorage/repodata

(d)rmrf VT/repodata

Step 5 :-Now create a file named base.repo vi /etc/yum.repos.d/base.repo


12/17

Step 6 :-Edit a file named rhel-debuginfo.repo vi /etc/yum.repos.d/rhel-debuginfo.repo

In this file enabled & gpgcheck must be 0

Step 7 :-Now, edit this file vi /etc/yum/pluginconf.d/rhnplugin.conf

Here also enabled & gpgcheck must be 0

Step 8 :-Now, edit last file vi /etc/yum.conf

Here also enabled & gpgcheck must be 0


13/17

Step 9 :-Install standalone service rpm ivh /mnt/Server/createrepo*.rpm

Step 10 :- Now we have to create repository

(a)createrepog /mnt/Server/repodata/comps-rhel5-server-core.xml /repo/Server

(b)createrepog /mnt/ClusterStorage/repodata/comps-rhel5-cluster-st.xml

/repo/ClusterStorage

(c)createrepog /mnt/Cluster/repodata/comps-rhel5-cluster.xml /repo/Cluster

(d)createrepog /mnt/VT/repodata/comps-rhel5-vt.xml /repo/VT

Step 11 :-Now clean the process yum clean all


14/17

Step 12 :-Now check the list all file in yum serveryum list all

Step 13 :- Now install the package from commandyum install


15/17

OUTPUT

After installing YUM server in linux .we can easily install any package.

Basic yum usage

On client side, to Search apackage, use the following syntax yum search

[root@RHEL03 Server]# yum search httpd

On client side, to import the GPG key, use the following syntax rpm -import

root@RHEL03 Server]# rpm --import http://192.168.1.101/server/RPM-GPG-KEY-redhat-

release

On client side, to install apackage, use the following syntax yum install . YUM

will find out if there is any dependency, and install that dependency before the installation. The

following command can be used to install the httpd (Apache Web Server) package.

[root@RHEL03 Server]# yum install httpd

To remove an installedpackage, use the following syntax yum remove .

[root@RHEL03 Server]# yum remove httpd

CONCLUSION

The whole project is all about installing packages in linux via YUM server (yellowdog updater

modified). Yum is an automatic updater and package installer/remover for RPM systems. It

automatically computes dependencies and figures out what things should occur to install packages. It

makes it easier to maintain groups of machines without having to manually update each one using

rpm.

Yum server is providing a very user friendly working system in linux. We can install packages from

other methods also but installing packages after setupof Yum server make it more easy.Yum is very

conservative. It will never perform the equivalent of a -force install. It was designed, as noted above,

by systems administrators to facilitate the consistent and scalable maintenance of systems, and thus

will balk at any action that might cause your system to enter ``package hell'' (a state of packageinconsistency). If yum refuses to do something, then the thing it refuses to do is probably a bad idea

for most people to think about. If you are skilled enough to know that it is really OK on YOUR

system, you are skilled enough to use rpm itself to override yum.
