Course Overview
Hi everyone and welcome. My name is Andrew Mallett and I'd like to introduce you to my course, Learning the Essentials of CentOS Enterprise Linux 7 Administration. Now, I'm the owner of The Urban Penguin within the UK and I train and consult in Linux and have done for many years now. I work both as a system administrator and a dabbling developer. The use of Linux, as you're probably already aware, is on the increase and you don't want to be left behind. So, no matter if you are starting out your career in system administration or you just want to complement other skillsets that you already have, expanding your CV, this course is going to get you started and up and running with CentOS 7. Very quickly and effectively you will soon understand the essentials of managing an enterprise Linux environment. Some of the major topics that we're going to cover include Linux permissions, the chmods and the chowns of the world. We'll be looking at running as the root user or the administrator and we'll using the command sudo or SU. We'll be looking at running commands across many systems at the same time as well as looking at how we can run commands both locally and remotely across our enterprise Linux systems. By the end of this Pluralsight course, you will know how to install and run commands on CentOS 7-based systems. Not wanting to stop here, you will be able to use regular expressions to search files and you'll be able to edit files either using VIM or dynamically using the Stream Editor Sed. You will be the Linux maestro you have always imagined. Before beginning this course, you should be familiar with the concepts of system administration and want to achieve Linux system administration as your goal.
