Aprovisionar un segundo controlador de Sitios web

Se aplica a: Windows Azure Pack

Windows Azure Pack: Sitios web puede tener un máximo de dos controladores de Sitios web. Para lograr alta disponibilidad, se recomienda encarecidamente que utilice este valor máximo y aprovisione un segundo controlador de Sitios web. Puede hacerlo de dos maneras:

• Al crear una granja de servidores
• Adición de un controlador a una granja de servidores existente

Agregar un segundo controlador de sitios web a una nueva granja de servidores (con Update Release 6 y versiones posteriores)

Con el Windows consola de administración de sitios web de Azure Pack, puede agregar un segundo controlador de sitios web al configurar una nueva granja de servidores.

1. Al seleccionar el tipo de controlador, seleccione Unir servidor a una nube de Sitios web existente como controlador secundario.
2. En la lista de claves del sistema y conexión de base de datosStrings, haga clic en Configurar.
3. En la ventana emergente, escriba los valores de estos campos:
   • Controlador principal
   • Nombre de usuario
   • Contraseña
4. Haga clic en Aceptar para configurar el segundo controlador.

Agregar un segundo controlador de sitios web a una granja de servidores existente

Use los siguientes scripts para agregar un controlador a una granja de servidores existente:

• OnStartSecondaryController.cmd : instala el Instalador de plataforma web (Web PI) en el servidor o en la máquina virtual con Windows 2012 que haya preparado. Después llama a los scripts HostingBootstrapperBootstrapper y OnStartSecondaryController sucesivamente para completar el aprovisionamiento del controlador secundario. Entre los parámetros necesarios se incluyen las credenciales administrativas de SQL Server y del controlador que se usarán en su instalación.

• HostingBootstrapperBootstrapper.ps1: llama a Archivos de programa\Microsoft\Web Platform Installer\WebpiCmd.exe para instalar el segundo controlador de Sitios web. Utiliza el mismo procedimiento que cuando se instala el controlador principal, pero descarta el portal de configuración especificando el modificador de línea de comandos /SuppressPostFinish.

• OnStartSecondaryController.ps1: copia datos de configuración del controlador principal al controlador secundario, incluidas las claves SystemCore y SiteRuntime y las cadenas de conexión de hospedaje y medición de recursos. Cuando finaliza, inicia WebFarmService.

• Common.ps1: proporciona funciones auxiliares para el script OnStartSecondaryController.ps1.

Pasos para ejecutar los scripts

1. Copie los archivos de script a una carpeta del servidor que será el controlador secundario.

2. Copie el archivo WebPlatformInstaller.msi a la misma carpeta que los scripts. Esto es necesario porque el script OnStartSecondaryController.cmd automatiza la instalación de Web PI.

3. Ejecute OnStartSecondaryController.cmd con derechos de administrador, proporcionando los parámetros que se describen en la tabla siguiente. Se necesitan privilegios de administrador para poder instalar los productos adecuados mediante automatización de Web PI y para que se pueda tener acceso al controlador principal mediante WinRM.

   Nota:

   En un escenario de GRUPO DE TRABAJO, puede que sea necesario habilitar WinRM en el controlador principal, o ejecutar los comandos del script OnStartSecondaryController.cmd manualmente.
