This series covers implementing and managing Red Hat Enterprise Linux (RHEL) v7. RHEL v7 is the leading commercial Linux server software used by corporations around the world. Topics covered by this series include installation, configuration, troubleshooting, and backup and recovery. The goal of this series is to prepare any systems administrator to be able to support RHEL v7 in a production environment.
[SOUND] In this series, we're gonna be taking a look at Red Hat Enterprise Linux version 7. Now most of you have already heard of the OS. It's why you're here, but for those who haven't, RHEL is the largest commercially supported version of Linux. And what that means is, you can go and you can pay for it, which I know sounds contradictory for Linux, that normally we get it for free from the various providers. But we can pay for it, and in exchange for that payment, we get support. We get an actual corporate entity sitting behind the distribution that's available to assist us when we have problems. And that's really something that's extremely important if you're using Linux in a production environment. And let me tell you, a lot of people are. When you go out on the Internet, the majority of web servers you hit these days are Linux-based web servers. Fortune 500 companies rely on it every single day. All of the big Tech startups that are out there using on a regular basis, and Red Hat is at the forefront of that. Now, because there's a pay element to it, a lot of people don't have a lot of exposure to it. But you'd actually be surprised. Many of the free Linux distributions that are out there, are based on the work that Red Hat does. So if you've run CENTOS, which is the Community Enterprise Operating System, it is actually build right off of the public open Source code from Red Hat Enterprise Linux. Oracle Linux, same thing. Built right off of Red Hat's code base, and even Amazon's Linux AMI that they use on Amazon web services that is used by millions of virtual machines around the world also built off of Red Hat's open source code base. So the work that Red Hat does to improve and secure their product, gets out there and improves other platforms too. So if you've worked with CENTOS, or the Linux AMI from Amazon, or Oracle Linux you've actually already worked with Red Hat, and your skillset moves right into it, and everything's nice and the same, and that works out great. But in addition if something goes wrong You can pick up the phone, open up a support ticket with Red Hat, and their engineers will help you through the problems. That's what makes it such a robust platform. Now, in this video series, what we're gonna do is we're gonna take a look not just at what Red Hat Enterprise Linux is, but how we can use it. And we're gonna run through some of the different configuration schemes and settings, the way that we configure the system and get it online, and make it where you can get out there in a production environment and use it to its fullest. We start by taking a look at how to install Red Hat Enterprise Linux. Either doing it manually or doing it automated. If you need to roll out to a thousand machines, you don't want to go and do this by hand. We'll show you how to create a custom installer and actually get that installation going. We'll show how to use the security features inside of Red Hat Enterprise Linux. There's SE Linux and Firewalld. There's all sorts of additional security sublayers that are in there. And we show how they work, how you configure them, and how you can maintain them to maintain the most secure operating system possible. We also spend a good bit of time looking at file systems, choosing the right file system really does have a big impact on how your server performs, and so we get a chance to see that and how it works inside of the Red Hat environment. And then lastly, we throw in some odds and ends. Some other services and things that you might need out there in the real world, like how to back up the system, how to do snapshots, how to install software, third-party software, and maintain that, how to use the graphical user interface as well as the command line. And all the other skills that are needed for a systems administrator that's gonna be supporting a Red Hat Enterprise Linux environment. So if you're that kind of person, if you're tasked to the job of supporting Red Hat, this is the place for you. If you just wanna learn more about it, if you're a hobbyist and you wanna explore the world of Red Hat Enterprise Linux, again, another great place to jump in. If you're just getting started with Linux, though, if you've never really touched the OS before, this might not be the best place for you to start. You might wanna check out some of the other shows we have on ITPRO.TV, like the Linux+ content, where we take you from no Linux skill all the way up to being proficient as a basic system administrator. That's a great starting point for you. But if you've already worked with Linux, and you're more concerned with just learning the differences in Red Hat and how we can support it in our environment, then this is the show for you. And if this sounds interesting, well stay tuned, cuz we've got episodes of Red Hat Enterprise Linux version 7 coming up next. [SOUND]
