We will review the basics of installing Red Hat Linux Enterprise 6 Update 4 for the Intel 64-bit platform in a virtualized infrastructure to prepare an environment to install an Oracle cluster and database(s). To simplify the process and to demonstrate package installation procedures, we will select the option to install the Basic Server and required packages to create a local yum repository from the installation media to install packages with dependencies.

If you have a Red Hat subscription, you can download RHEL 6 ISO image files from Red Hat’s Software & Download Center customer portal. If you do not already have a subscription, you can obtain a free 30 evaluation subscription from Each of the DVD ISO images are about 3-4 GB in size. After you download the ISO image, create a bootable DVD and USB and reboot the system to start the installation.

In the Boot Menu, if there is no response within 60 seconds, the default option to Install or upgrade an existing system using the GUI will be executed.

You will be given the option to perform a disk check on the installation media. Click on Skip.

Packages completed


Let’s remount our DVD so that we can copy all the RPMs from the DVD to a centralized location on the file system:
Mount cd

In order to setup a local Yum repository, we need to install the createrepo package. The createrepo package has dependencies on two additional packages: deltarpm and python-deltarpm. To successfully install the createrepo package, we will invoke the rpm command with the -ihv option and provide the names of all three packages:
Rpm install

We have successfully installed the createrepo package. The next step will be to copy all the RPMs from the DVD to an area on the local file system. In my example, I am copying the files to the /tmp file system but you will want to select a more permanent location. After the files are copied, we will invoke the createrepo command and provide the location of the directory where the RPMs were copied to:

We have successfully created our local yum repository. Now we are ready to install and update packages with yum.
