Der GL134-Kurs ist so konzipiert, dass er einem identischen Themenkomplex wie der Red Hat® RH134-Kurs abdeckt, mit dem zusätzlichen Vorteil sehr umfangreicher Laborübungen und detailliertem Vortragsmaterial.

Die Themen die in diesem Kurs zusammen mit dem GL124-Kurs behandelt werden, decken die Zertifizierungsanforderungen der Prüfung zum Red Hat Certified System Administrator (RHCSA) ab.

Zu den behandelten Themen gehören die Automatisierung der Installation mit Kickstart, Aufbau von Command Line Befehlen und Tools auf mittlerem und fortgeschrittenem Niveau, Fehlerbehebung, Konfiguration von Netzwerk-Dateifreigaben, Verbindung mit einem Verzeichnisdienst, Verwaltung erweiterter Sicherheitseinstellungen, Wartungsaufgaben und Kernel-Tuning.

Red Hat® ist ein eingetragenes Warenzeichen von Red Hat.

Voraussetzungen: Kurs GL124 absolviert oder gleichwertige Kenntnisse
Distribution: Centos 8 / Red Hat Enterprise Linux 8
