Regardless of the polls, this is not a democracy. Today I am starting my Red Hat course, and it's gonna focus on the certification "Red Hat Certified System Administrator". I am excited to get started on this class. However, this begs the question, am I finished with Network+? Of course not! I will continue studying it on my own. My new plan is to do chapter overviews of each one, rather than specifically going through each subject.
If you couldn't already tell, this blog is sort of an introduction to my Red Hat class. Nevertheless, today our teacher Mr. Elkner guided us on how to partition and install Red Hat onto my system. This is not a dual-boot installation however, because we are using Virtual Box! Let me tell you, this Virtual Box thing is something else. Quite the program to use if you're interested in utilizing a new operating system, and not wanting to take risks. By this I mean, not messing up your system and having consequences; all in all, a great thing.
The way we did it, is that Mr. Elkner went onto our computers while we were gone, and put the iso for Red Hat Enterprise Linux Server, kind of like Santa, except he didn't break into our house. Then he directed us through the installation. We unpack the ISO using VirtualBox directly, and it will take it, and create a virtual system. What we were trying to do with this, was create two servers. One with a GUI and one without. Now to do this, we would need two different versions of the ISO. One with the GUI and one without! Haha I said that twice now. Anyways, Mr. Elkner directed us the first time on how to install "Server1".
To do this, start off by giving this virtual machine 20 GB. Once you get into the installer, you must make three different partitions, one called "sda 1" (/boot) with 500 MiB, one called swap with 2 GB, and one which was the actual root (/) which had 10 GB. Now, swap may have had a little more space then specified in the textbook, but we were testing out whether it would work, and it did. The one important thing to note, when you get to a certain point in the installation, it will have "Network" displayed as an option. It will be disabled, which is odd, and you must enable it to make it work as a server. From there, the installation is pretty straightforward.
Then there's "Server2" which is the one without the GUI. For this, Mr. Elkner has not guided us, we have to work together (with my peers) to make it work. This time, we did the exact same process, the installer lets you choose which type of installation you want, this time I chose "minimal" since we don't need a GUI for this. The process is literally the same, nothing for me to add. That basically ended my first assignment, and CHAPTER! Yes, what a short chapter! Don't expect the rest to be like them haha. Thanks for reading, and goodbye.
Review Q/A:
1. You do not want to buy a RHEL license, but you want to create an environment to practice for the exam. Which distribution should you use?
A: CentOS or Scientific Linux.
2. Why can’t you use a 32-bit version of RHEL to prepare for the exam?
A: Because the system is 64-bit.
A: 512 MB
A: To automatically configure the region and timezone you are in.
5. You want to install a virtual machine on a computer that does not have an optical disk drive. What is the easiest alternative to perform the installation?
A: Use a USB drive.
A: Cause it's easier to use.
A: XFS
A: Yes.
A: Support
10. Which installation pattern should you use if you have a very limited amount of disk space available?
A: Minimal.
1 GiB will actually be enough for the swap partition. The iso image I placed in a shared space on each machine is actually for Centos 7, not REL.
ReplyDeleteExcellent documentation, as usual!
