Installing CentOS 6.4 from a Net Install Image on a Virtual Host

An Opportunity To Play Around with CentOS

One of the personal projects that I’ve always had itching away at the back of my mind was the urge to revamp my home network monitoring and security.  One of the tools that I love using for network monitoring is Xymon.  However, this gives me an opportunity to do things slightly different.  I have decided to give CentOS a go instead of my typical choice of Debian for a Linux distro in a server environment.  I am curious to see what advancements have been made in the RPM world, and I’d like to keep my Red Hat skills up to date.  What better way to do so than to set up a CentOS server with some production tools and services on it :)

Pre-installation Setup

So here we are, I have the CentOS Netinst (Net Install) image loaded into a VM, and I boot up the guest.

Since this is a fresh install on a 20GB virtual disk, I’m going to select “Install or upgrade an existing system” here.

I press “enter” and lots of console logging and scrolling action takes place.

Eventually I am prompted to “test the media”.  Usually this is referring to a physical CD typically used to install the OS on a physical server.  To me the phrasing feels a bit antiquated in this day of cloud services.

In any case, I still say yes, hoping that it will catch any errors in the ISO image file before I run into a bug during the installation process.  Better safe than sorry.

After the virtual disk is “successfully verified” to be OK, I try to move forward with the installation.

Be sure to note that after your virtual disk is verified OK, that the installer may decide to eject your CD media, in order to give you an opportunity to test other media.

Since I have no other media to test, this is actually kind of annoying. In order to continue with the installation, I have to go into the VM settings and re-connect the CDROM to the VM.

Select your language and keyboard options if the defaults are not suitable.  Otherwise, just  move past these dialogues by selecting “OK”, or hitting enter.

 

When you are asked “What type of media contains the installation image?”, select “URL”.
