Students who have not taken a previous Red Hat course are encouraged to take either System Administration I if they are new to Linux, or the RHCSA Fast Track course (RH200) if they are experienced with enterprise Linux administration.

Prerequisites for this course: Red Hat System Administration I (RH124)

Course overview

The course is focused on deploying and managing network servers running caching Domain Name Service (DNS), MariaDB, Apache HTTPD, Postfix SMTP nullclients, network file sharing with Network File System (NFS) and Server Message Block (SMB), iSCSI initiators and targets, advanced networking and firewalld configurations, and the use of Bash shell scripting to help automate, configure, and troubleshoot the system. Through lectures and hands-on labs, students who have already earned the RHCSA certification will be exposed to all competencies covered by the Red Hat Certified Engineer (RHCE) exam (EX300).

Outline for this course

- Control services and daemons
- Manage IPv6 networking
- Configure link aggregation and bridging
- Control network port security
- Manage DNS for servers
- Configure email delivery
- Provide block-based storage
- Provide file-based storage
- Configure MariaDB databases
- Provide Apache HTTPD web service
- Write Bash scripts
- Bash conditionals and control structures
- Configure the shell environment
- Comprehensive review

Audience & Prerequisites

Red Hat System Administration III is intended for experienced Linux administrators wishing to learn enterprise-level automation techniques through scripting, how to deploy and secure network services, and how to manage other key security features of Red Hat Enterprise Linux. Students in this course should have earned their RHCSA or have equivalent skills.

Prerequisites for this course:

RHCSA certification or equivalent experience
For candidates who have not earned their RHCSA certification, confirmation of the correct skills and knowledge can be obtained by passing the online skills assessment.
