Course Description

Students learn how to install, configure and maintain an Enterprise Linux system in a networked environment. Basic administrative tasks are covered such as: creating and managing users, creating and maintaining file systems, determining and implementing security measures and performing software installation and package management. Linux networking topics include installing and supporting SSH, NFS, Samba and the Apache Web server. Common security issues are discussed and several software tools are introduced such as the PAM modules that help secure the operating system and network environment. Comprehensive hands on exercises are performed throughout the course to reinforce learning and develop skills and competency. Upon successful completion of this course, students will be prepared to maintain Linux systems in a networked business environment.

Although the course includes installing and configuring a CentOS 7 / RHEL 7 Linux system, much of the course content also applies to Oracle, Ubuntu, Scientific and other current versions of mainstream Linux distributions. Labs include user and group maintenance, system backups and restoration, software management, administration tasks automation, file system creation and maintenance, managing remote access, working with cron, and configuring basic file sharing and Web services, as well as working with system logging utilities such as rsyslog and much more.

Course Prerequisites

Experience with common UNIX/Linux user-level commands, such as for moving, copying and editing files. Experience with the vi editor is a plus. Attendance at the UNIX/Linux Fundamentals course provides a solid foundation.

Testimonials

The instructor has extensive knowledge of Linux and course materials and presented it very well. I have recommended this Linux course to a colleague who is planning to take this course in the near future. I have attended many training courses and feel this was the best course I have taken.

The instructor was very knowledgeable of the content and would make sure that the content was understood before moving onto the next subject. I like the fact that HOTT keeps the class sizes small. I will definitely look to HOTT for future training.
