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).
