Effettuare il provisioning di un secondo controller di Siti Web

Si applica a: Windows Azure Pack

Windows Azure Pack: Siti Web può disporre di un massimo di due controller di Siti Web. Per la disponibilità elevata, si consiglia di rispettare questo numero massimo e di effettuare il provisioning di un secondo controller di Siti Web. È possibile eseguire questa operazione in uno dei due modi seguenti:

• Quando si crea una nuova farm
• Aggiungere un controller a una farm esistente

Aggiungere un secondo controller siti Web a una nuova farm (con l'aggiornamento versione 6 e successive)

Usando la console di gestione Windows Siti Web di Azure Pack, è possibile aggiungere un secondo controller siti Web quando si configura una nuova farm.

1. Quando si seleziona il tipo di controller, selezionare Aggiungi server a un cloud Siti Web esistente come controller secondario.
2. Nell'elenco delle chiavi di sistema e delle stringhe di connessione del database fare clic su Configura
3. Nella finestra popup immettere i valori per questi campi:
   • Controller primario
   • Nome utente
   • Password
4. Fare clic su OK per configurare il secondo controller.

Aggiungere un secondo controller siti Web a una farm esistente

Usare gli script seguenti per aggiungere un controller a una farm esistente:

• OnStartSecondaryController.cmd : installa l' Installazione guidata piattaforma Web (PI Web) in Windows Server 2012 o nella macchina virtuale preparata. Chiama poi gli script OnStartSecondaryController e HostingBootstrapperBootstrapper in successione per completare il provisioning del controller secondario. I parametri obbligatori prevedono le credenziali amministrative del controller e SQL Server che verranno utilizzati nella configurazione.

• HostingBootstrapperBootstrapper.ps1: chiama Programmi\Microsoft\Web Platform Installer\WebpiCmd.exe per installare il secondo controller di Siti Web. Tramite questo script viene utilizzata la stessa procedura di installazione del controller primario, ma viene eliminato il portale di configurazione specificando l'opzione della riga di comando /SuppressPostFinish.

• OnStartSecondaryController.ps1: copia i dati di configurazione dal controller primario nel controller secondario, incluse le chiavi SystemCore e SiteRuntime e le stringhe di connessione di conteggio delle risorse e di hosting. Al termine, avvia WebFarmService.

• Common.ps1: fornisce funzioni di supporto per lo script OnStartSecondaryController.ps1.

Passaggi per eseguire gli script

1. Copiare i file script in una cartella nel server che diventerà il controller secondario.

2. Copiare il file WebPlatformInstaller.msi nella stessa cartella degli script. Questa operazione è necessaria perché tramite lo script OnStartSecondaryController.cmd viene automatizza l'installazione di PI Web.

3. Eseguire OnStartSecondaryController.cmd con diritti di amministratore, fornendo i parametri descritti nella tabella riportata di seguito. I privilegi amministrativi sono necessari affinché sia possibile installare i prodotti appropriati tramite l'automazione di PI Web e sia possibile accedere al controller primario tramite Gestione remota Windows.

   Nota

   In uno scenario WORKGROUP, potrebbe essere necessario abilitare Gestione remota Windows nel controller primaria o eseguire manualmente i comandi nello script OnStartSecondaryController.cmd.
