Umfassender Einstieg in Enterprise Linux
Der GL124 ist ein Grundlagenkurs und deckt inhaltlich die identischen Themen wie der Red Hat® RH124 ab. Im Vergleich RH124 wurden zusätzlich umfangreiche Laborübungen eingearbeitet um das theoretisch erlernte Wissen weiter zu vertiefen.

Zielgruppe
Benutzer ohne Unix-Erfahrung oder Einsteiger, die Linux-Systeme in der Praxis kennen lernen wollen.

Kursziel

Es wird das Wissen erarbeitet, welches an der Zertifizierung zum Red Hat Certified System Administrator (RHCSA) geprüft wird. Dies erstreckt sich über Themen wie, Kommandozeilen-Tools, Installation von RHEL, Remote-Administration-Techniken, die Verwaltung von lokalem Speicher, Systemüberwachung, Basis- und Benutzersicherheit, Systemadministration, Netzwerkdienste und der Einsatz von FTP-und Web-Servern.

Vorkenntnisse
Allgemeine Kenntnisse eines Betriebssystems sind von Vorteil.
