Linux System Administration I

Course Number:


This class is designed to ease Java, JBoss, Web, and Software developers, Windows admins, hardware techs, novice Unix users, and network admins into Linux/RedHat administration. This class runs on a Linux 6.3 kernel and covers more than the RedHat Admin I class. Users will learn the underlying file system, basic Unix utilities, text processing commands, and “user” administration.

Other topics including formatting a disk, making a file system, mounting file systems, mounting NFS file systems, and configuring system control files for automating the mounting of directories. The subject matter also includes directory and file permissions, process commands, backup and recovery techniques, output redirection, piping, input/output of data, and basic administration procedures using GUIs and command-line. This basic course is a prerequisite for the “System Administration II” classes from ntier Training, RedHat, Oracle/Solaris, or others. This class is customizable to meet the needs of the customer.


This course is intended for novice Unix Administrators, Java, JBoss, C, C++, and other Software Developers, Web and XML Developers, advanced Unix Users, IT managers, users who have to do data manipulation and do advanced print formatting, hardware technicians, OS installers, and network administrators.
