RH199 RHCSA Rapid Track Course

This course is geared toward Windows system administrators, network administrators, and other system administrators who are interested in supplementing current skills or backstopping other team members, in addition to Linux system administrators who are responsible for these tasks:

• Configuring, installing, upgrading, and maintaining Linux systems using established standards and procedures
• Providing operational support
• Managing systems for monitoring system performance and availability
• Writing and deploying scripts for task automation and system administration

On completion of course materials, students should be prepared to take the Red Hat Certified System Administrator (RHCSA) exam.

Note: This course builds on a student's existing understanding of command-line based Linux system administration. Students should be able to execute common commands using the shell, work with common command options, and access man pages for help. Students lacking this knowledge are strongly encouraged to take Red Hat System Administration I (RH124) and II (RH134) instead.

Students attending this course should have basic experience with the following, with minimal dependence on documentation:

• Linux (some of the course may be review)
• The bash shell, including job control (&, fg, bg, jobs), shell expansion (command, tilde, globbing, brace, protection from expansion), I/O redirection, and pipes
• IPv4 networking addressing and routing concepts, TCP/UDP, and ports
• Navigation of the GNOME 3 interface
• Editing text files from the command line with vim or other available programs
• Finding information in man pages and info nodes
• The concept of file permissions
• Interactive installation of Red Hat Enterprise Linux
• Per-user 'at' and 'cron' jobs
• Use of archival utilities such as 'tar', 'zip', and compression utilities
• Absolute and relative paths
• Finding files with 'find' and 'locate'

If you do not have experience with fundamental Linux computer concepts, we advise you to start with the Red Hat System Administration I (RH124) course instead.
