Script de ejemplo de PowerCLI para actualizar Horizon Agent en máquinas de escritorios Linux

Puede personalizar y usar el siguiente script de ejemplo para actualizar Horizon Agent en varias máquinas virtuales Linux.

El script carga el archivo tar comprimido (.gz) del instalador en cada máquina virtual antes de instalar Horizon Agent. La tarea de carga puede requerir un tiempo considerable, sobre todo si hay un número considerable de máquinas virtuales y la velocidad de la red es baja. Para ahorrar tiempo, puede ejecutar el script que usa SSH o poner el archivo tar del instalador en una ubicación compartida que esté disponible para todas las máquinas virtuales, de modo que no sea necesario cargar el archivo.

Para copiar y pegar el contenido del script sin saltos de página, use la versión HTML de este tema, disponible en la página de documentación de Horizon 7 en https://docs.vmware.com/es/VMware-Horizon-7/index.html.

Entrada del script

Este script lee un archivo de entrada, que se describe en Archivo de entrada de los scripts PowerCLI de ejemplo para implementar escritorios Linux. Este script también solicita de manera interactiva la siguiente información:

• Aceptación del acuerdo de licencia de usuario final (EULA) de Horizon Agent
• Dirección IP de vCenter Server
• Nombre de inicio de sesión de administrador para vCenter Server
• Contraseña de administrador para vCenter Server
• Nombre de inicio de sesión de administrador para el host ESXi
• Contraseña de administrador para el host ESXi
• Nombre de inicio de sesión de usuario para el sistema operativo invitado Linux
• Contraseña de usuario para el sistema operativo invitado Linux
• Ruta de acceso del archivo tar comprimido (.gz) de Horizon Agent
• Actualizar a máquina virtual administrada
• Instalar la función de redireccionamiento de tarjeta inteligente
