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://docs.vmware.com/de/VMware-Horizon-7/index.html verfügbar ist.
