Here, Sandra discusses the ins and outs of planning a Red Hat Enterprise Linux server installation.
- [Narrator] In this chapter, Red Hat Enterprise Linux Basics: Planning a Red Hat Enterprise Linux Installation, we'll take a look at some factors you need to consider before you download and install your Red Hat Enterprise Linux operating system. We'll cover download options, and some system planning considerations. In this course, we'll be installing Red Hat Enterprise Linux Version Seven on a virtual machine. In preparation for our installation, I downloaded Virtual Box. In order to get started, we'll need to download installation media from Red Hat Enterprise Linux customer portal.
From the download page, you'll see the option for a minimal boot ISO, or a binary DVD. Let's take a look at the customer portal so you can see what I'm talking about. This is the download page for Red Hat Enterprise Linux in the customer portal. If I scroll down to the bottom here, you'll see that you can download a Red Hat Enterprise Linux 7.2 boot ISO, or a Red Hat Enterprise Linux 7.2 binary DVD. We're gonna use the binary DVD ISO image to boot and perform the entire installation without additional package repositories.
If you're good at building, or otherwise working with repositories, you can use the boot ISO image. While it can be used to boot the installation program, it requires adding package repositories and quite a bit more legwork. At the top of the download page, you'll see that you have a product variant drop down menu, as well as the version and the architecture. We're gonna go with the default, Red Hat Enterprise Linux server, the latest version 7.2, and the X86 architecture.
When you're figuring out which variant is best for your needs, you can check out www.redhat.com, Linux Platforms Enterprise Linux Technologies. You're also gonna wanna have an idea of the software packages that you're gonna want to install. During the installation process, you'll be able to select a pre-defined set of packages, called a base environment. It's pretty valuable before you begin your install to have an idea of what you need in your environment. Some of the options you'll have include a minimal base environment, which includes a basic set of software packages.
You can have a server type base environment. This will set you up with infrastructure, storage, and web content packages. You can also choose the host base environment. This will set you up for virtualization. Keep in mind that only one software environment can be selected at installation time. Once your base environment is selected, you can select add-on packages to round out your installation environment. When planning disk space for Version Seven, Red Hat recommends ten gigs of disk for all supported architectures.
It's important to have an idea of how you might wanna partition your drive as well. For this course, we'll allow the installation program to initially configure partitioning, and make changes later in the course. There's other things that you'll wanna know before you start the installation process as well, like the plan network configuration. You're also going to need to create at least a root user, so it's a good idea to determine the root credentials before you start the process. In the next video, we'll begin installing Red Hat Enterprise Linux.
