Local RHEL Installation Source

For RedHat System which are not connected to the internet, it’s good to have a local dvd as an installation source. Here’s how to do it:

First, mount the Installation DVD:

mkdir /media/cdrom && mount /dev/cdrom /media/cdrom

Now, let’s quickly create an entry in /etc/yum.repos.d/ that points to your dvd

cat >/etc/yum.repos.d/rhel_dvd.repo <<EOF
mediaid=$(head -n1 /media/cdrom/.discinfo)
name=RedHat Enterprise Linux $(sed -n '2p' /media/cdrom/.discinfo | rev | cut -c -3 | rev) DVD

That’s it! Now you can use the following command to install packages without contacting RedHat Network:

yum install strace --noplugins
