Vous pouvez personnaliser et utiliser l'exemple de script suivant pour mettre à niveau Horizon Agent sur plusieurs machines virtuelles (VM) Linux. Ce script utilise SSH pour exécuter des commandes sur les VM Linux.
Pour copier et coller le contenu du script sans saut de page, utilisez la version HTML de cette rubrique, disponible sur la page de documentation d'Horizon 7 à l'adresse https://www.vmware.com/support/pubs/view_pubs.html.
Entrée du script
Ce script lit un fichier d'entrée, qui est décrit dans la section Fichier d'entrée des exemples de scripts PowerCLI pour déployer des postes de travail Linux. Ce script demande également de façon interactive les informations suivantes :
- Acceptation du CLUF (contrat de licence utilisateur final) d'Horizon Agent
- Adresse IP de vCenter Server
- Nom de connexion de l'administrateur pour vCenter Server
- Mot de passe de l'administrateur pour vCenter Server
- Nom de connexion de l'administrateur pour l'hôte ESXi
- Mot de passe de l'administrateur pour l'hôte ESXi
- Nom de connexion de l'utilisateur pour le système d'exploitation invité Linux
- Mot de passe de l'utilisateur pour le système d'exploitation invité Linux
- Chemin de l'archive Horizon Agent
- Mise à niveau vers une machine virtuelle gérée
- Installation de la fonctionnalité de redirection de carte à puce
