Join Grant McWilliams for an in-depth discussion in this video What you should know, part of RHCE Cert Prep: Advanced Disk Systems and System Backup.
- [Narrator] In this course we will be using CentOS 7 Linux. CentOS 7 is near exact clone of Red Hat Enterprise Linux 7. CentOS 7 is freely downloadable from centos.org. If you have access to Red Hat Enterprise Linux 7, you can use that as well. We'll be running CentOS 7 in a virtual machine and virtual box. You can run virtual box on most any host operating system, including Windows, Mac OS, or Linux. You may want to have high-speed internet for doing Linux OS software updates. You will also want to have 15 to 20 gigabytes of free hard drive space for the Linux virtual machine.
You can also use any CentOS 7 server with GUI installation. This means choosing server with GUI on the software selection screen. You will also want to make sure the first user is an administrator. The first course in this RHCE Certification Track is RHCE Cert Prep: Networking and SSH. That course covers the initial CentOS 7 installation and configuration. If your took RHCE Cert Prep: Networking and SSH, you can keep using that CentOS 7 virtual machine if you wish.
If you did not take that course, we have provided videos in this course for installing CentOS 7 and installing virtual box guest additions. I do, however, recommend taking RHCE Cert Prep: Networking and SSH, as it creates the foundation for the rest of the RHCE Cert Prep series.
