Course Objectives
Linux is rapidly finding its way into business, education and government. Due to its outstanding reliability, performance and low cost, Linux is being used extensively for file, database and web server applications. Of all the various Linux systems available, Red Hat Enterprise Linux (RHEL) has become the corporate Linux standard.
The Red Hat Enterprise Linux 6 System Administration Part 1 course is aimed at users who have a requirement to manage Enterprise Linux systems, not just RHEL but also any of the rebuild projects like CentOS and Scientific Linux.
This course assumes the delegate has no prior knowledge of a UNIX or Linux system and therefore starts from the basics. The course then moves on to show delegates how to manage their Enterprise Linux systems, including; adding and managing user accounts, installing software and hardware, accessing disk devices, booting up and shutting down the systems.
At the end of the course, delegates will be able to:
- Understand the history of Unix and Linux.
