Sie können das nachfolgend aufgeführte Beispielskript für ein Upgrade von Horizon Agent auf mehreren virtuellen Linux-Maschinen (VMs) anpassen und anwenden.

Dieses Skript lädt das TAR-Archiv des Installationsprogramms auf jede VM hoch, bevor Horizon Agent installiert wird. Die Upload-Aufgabe kann sehr viel Zeit in Anspruch nehmen, vor allem wenn eine große Anzahl von VMs beteiligt und die Netzwerkgeschwindigkeit langsam ist. Um Zeit zu sparen, können Sie das Skript ausführen, das SSH verwendet, oder das TAR-Archiv des Installationsprogramms an einem freigegebenen Speicherort ablegen, der für jede VM verfügbar ist, wodurch das Hochladen der Datei nicht erforderlich ist.

Für das Kopieren und Einfügen des Skriptinhalts ohne Seitenumbrüche verwenden Sie die HTML-Version dieses Themas, die auf der Dokumentationsseite von Horizon 7 unter https://www.vmware.com/support/pubs/view_pubs.html verfügbar ist.

Skripteingabe

Dieses Skript liest eine Eingabedatei, die im Kapitel Eingabedatei für die PowerCLI-Beispielskripts zur Bereitstellung von Linux-Desktops beschrieben ist. Es gibt verschiedene Eingabeaufforderungen für die folgenden Informationen aus:

  • Annahme der Horizon Agent-Endbenutzerlizenzvereinbarung (EULA)

  • IP-Adresse von vCenter Server

  • Anmeldename des Administrators für vCenter Server

  • Kennwort des Administrators für vCenter Server

  • Anmeldename des Administrators für den ESXi-Host

  • Kennwort des Administrators für den ESXi-Host

  • Anmeldename des Benutzers für das Linux-Gastbetriebssystem

  • Kennwort des Benutzers für das Linux-Gastbetriebssystem

  • Pfad für das Horizon Agent-TAR-Archiv

  • Aktualisieren auf verwaltete VM

  • Installieren der Smartcard-Umleitungsfunktion
