Contents and Overview

This training program includes 2 complete courses, carefully chosen to give you the most comprehensive training possible.

The first course, Beginning CentOS 7 Administration starts with setting up a complete training laboratory using virtualization and see the possibilities with CentOS 7. You’ll start by learning how to install CentOS 7, see the benefits of it, download and confirm checksum on Windows or OS X, run a net installation over HTTP, and troubleshoot the system. Then you’ll learn how to set up a full-blown Virtual box Training lab. You’ll learn to install and adjust machines to make them communicate and see how to reset the machine. Next, you’ll configure the system learning static network connection. Moving on, we’ll walk through managing the system and managing packages with Yum. You’ll then troubleshoot, configure, synchronize, and install packages and create repositories and packages. Finally, you’ll deep dive into administering the file system, where you’ll learn to create a virtual block, format, maintain, and extend the capacity of the file system.

The second course, Mastering CentOS 7 Linux Server start by exploring the administration tools of CentOS 7 Linux server and implementing some of the most common Linux services. You'll get your hands on CentOS 7's built-in security tool. Next, you will be introduced to the most commonly used services and shown in detail how to implement and deploy a secure and production-grade environment for your organization following the open-source DevOps model. Then, you will start to monitor your infrastructure/server using open-source tools. You will then move on to master virtualization and cloud computing techniques by deploying and configuring IAAS (Infrastructure as a Service). After that, you will work on open-source tools for the configuration and management of multiple nodes. Additionally, you will learn about RAID software-based storage and its advanced configurations. By the end of this course, you will have learned to monitor servers/infrastructure and master the art of virtualization, cloud computing techniques, configuration management, software-based storage (RAID), and some security tweaks.
