About This Course
Red Hat Enterprise Linux is the world's leading enterprise Linux platform, powering mission-critical workloads across banking, telecoms, government, healthcare, and cloud-native environments. As organisations accelerate their digital transformation journeys, the demand for certified, competent RHEL administrators continues to outpace supply — making this training one of the most strategically valuable investments an IT team can make.
This ten-day programme delivers deep, hands-on coverage of RHEL system administration from the ground up, building progressively through installation and configuration, user and storage management, networking, automation, security hardening, and troubleshooting. Each module is grounded in real enterprise scenarios, ensuring that participants leave with practical skills they can apply immediately in production environments.
Designed for systems administrators, infrastructure engineers, and IT operations staff, the course bridges the gap between theoretical Linux knowledge and the operational discipline required to manage RHEL systems at scale. Whether your organisation runs on-premises servers, hybrid cloud infrastructure, or containerised workloads, this training provides the technical foundation to manage it reliably and securely.
TrainingComplex delivers this programme through a combination of structured instruction, live lab exercises, and scenario-based problem-solving — giving participants repeated hands-on exposure to the tools, commands, and workflows used by RHEL professionals every day. Participants who complete the programme will be well-positioned to pursue Red Hat Certified System Administrator (RHCSA) and Red Hat Certified Engineer (RHCE) certification exams.

Frequently Asked Questions
Do I need prior Linux experience to attend this course?
Participants should have at least basic familiarity with IT concepts and ideally some exposure to a command-line interface. The course begins with foundational content before advancing to more complex topics, making it accessible to those with limited Linux experience provided they are comfortable in a technical environment.
Will this course prepare me for Red Hat certification exams?
Yes. The course content closely aligns with the objectives of the Red Hat Certified System Administrator (RHCSA) exam and provides a solid foundation for the Red Hat Certified Engineer (RHCE) exam. While the certification exams are administered separately by Red Hat, participants who engage fully with the lab work will be well-prepared to sit them.
What equipment or software do I need to bring?
For in-person sessions, TrainingComplex provides all lab infrastructure including pre-configured virtual machines running RHEL. Participants attending the live virtual sessions will receive setup instructions in advance to configure a suitable local lab environment using a provided RHEL evaluation subscription.
Is a certificate of completion issued at the end of the course?
Yes. All participants who attend and complete the programme receive a TrainingComplex Certificate of Completion in Red Hat Enterprise Linux Administration. This is separate from the official Red Hat certification and serves as evidence of professional development for your employer or professional portfolio.
What version of RHEL is used in this training?
The course is delivered using Red Hat Enterprise Linux 9, the current major release. Where relevant, differences from RHEL 8 are highlighted to ensure participants managing mixed environments are fully informed of version-specific behaviour and commands.
