RH124: Red Hat System Administration I

This is the first of two courses covering the core system administration tasks needed to manage Red Hat Enterprise Linux servers. This course is based on Red Hat® Enterprise Linux 8.

Red Hat System Administration I (RH124) is designed for IT professionals without previous Linux® system administration experience. The course provides students with Linux administration "survival skills" by focusing on core administration tasks. This curriculum also provides a foundation for students planning to become full-time Linux system administrators by introducing key command-line concepts and enterprise-level tools.

The concepts learned in this training are further developed in the follow-on course, Red Hat System Administration II (RH134).

  • Impact on the organization

    This course is intended to develop the skills needed for basic administration and configuration of Red Hat Enterprise Linux. This course introduces key command-line concepts and enterprise-level tools, laying the foundation for the rapid deployment of Red Hat Enterprise Linux. It also introduces the basic administration skills needed for resolving configuration issues and integrating Red Hat Enterprise Linux systems with other existing environments. It lays the foundation for secure user and group administration, and develops skills that allow administrators to use available storage solutions more efficiently and securely. This is the first of a two course series that takes a computer professional knowing nothing about Linux to being a fully capable Linux administrator.

    Red Hat has created this course in a way intended to benefit our customers, but each company and infrastructure is unique, and actual results or benefits may vary.
