Just found out that we can install packages under Red Hat as a group, instead of individual ones, which will be a big time saver, along with trying to remember the name of the individual packages. I've seen a number of tutorials online for this and I think they either fall short or are not clear. So here is my attempt at it and this blog entry assumes the end user has some basic Linux skills and basic knowledge of Red Hat.

Step-by-step instructions on setting up the following:

- setup local yum repo

- copy down the correct xml file

- run the commands to set it yum and test

I'm using RHEL6 as a VM, however this should work for either CentOS or Scientific Linux (I've only tested this on RHEL6).

After starting up your VM, log in, and lets first create the local repo. All commands are run as user root.

Mount the install DVD

Code:

mount -t iso9660 /dev/sr0 /media/dvd

Test that the DVD has mounted and you should see it

Code:

mount

Change into the RHEL6 DVD

Code:

cd /media/dvd/Packages

Make a directory to copy all rpm down to

Code:

mkdir -p /tmp/local_repo

Copy all rpm in the Packages directory to /tmp/local_repo

Code:

cp -R * /tmp/local_repo

Change into the repodata directory on the RHEL DVD and copy down the comps-rhel6-Serverl.xml.gz. This file will have a long string preceding the comps part of the file name

Code:

cp -i (file-name-here)-comps-rhel6-Server.xml.gz /tmp/local_repo

Change into /tmp/local_repo and setup the local repository with the following package and following command:

Code:

rpm -ivh createrepo python-deltarpm deltarpm

Unzip the comps-rhel6-Server.xml.gz file

Code:

gunzip (file-name-here)-comps-rhel6-Server.xml.gz

Run the commands to createrepo with the -g flag (groupfile)

Code:

createrepo -g /tmp/local_repo/(file-name-here)-comps-rhel6-Server.xml  /tmp/local_repo

Create the local repo by doing the following:

Code:

cd /etc/yum.repos.d 

vim local.repo

For the local.repo file populate it with the following:

Code:

[server] 
name=RHEL6
baseurl=file:///tmp/local_repo 
enabled=1 
gpgcheck=0

Save the file and run the following commands

Code:

yum clean all ; yum makecache ; yum grouplist ; yum list all

To test, install the Virtualization Group, which would be KVM software suite, with the following commands

Code:

yum groupinstall -y "Virtualization ; yum groupinstall -y "Virtualization Client" ; yum groupinstall -y "Virtualization Platform"
