It starts by installing Red Hat Enterprise Linux, after which basic utilities are covered. Then, it will dig into the different ways to log in to a Linux server, and to run administrator tasks. In the last three lessons of this module, how to work with users and permissions and how to configure networking is discussed.Module 2, “Operating Red Hat Enterprise Linux Servers,” will teach the common tasks that are involved in day-to-day administration of RHEL servers. This includes installing software, managing processes, configuring logging, working with virtual machines, and managing storage, which is about partitions and logical volumes.Module 3, “Performing Advanced System Administration Tasks,” goes over the tasks that won't be performed on a daily basis. Managing the Linux kernel and the boot procedure will be discussed, and in the last part of this module, there will be a walk-through of some common troubleshooting scenarios.Module 4, “Managing Network Services,” shows how to configure those services where networking is involved. It starts by looking at the SSH server, followed by the Apache web. Next, SELinux, a vital part of RHEL that helps make it a secure platform, will be explained. Firewalling, network based automatic installation, and time are also covered.Module 5 provides an RHCSA Sample exam.About Pearson Video TrainingPearson publishes expert-led video tutorials covering a wide selection of technology topics designed to teach you the skills you need to succeed.
