Zřízení druhého kontroleru webů

Platí pro: Windows Azure Pack

Windows Azure Pack: Weby můžou mít maximálně dva kontrolery webů. Pro zajištění vysoké dostupnosti důrazně doporučujeme tento maximální výkon provést a zřídit druhý kontroler webů. Můžete to udělat jedním ze dvou způsobů:

• Při vytváření nové farmy
• Přidání kontroleru do existující farmy

Přidání druhého kontroleru webů do nové farmy (s aktualizací Update Release 6 a novější)

Pomocí konzoly pro správu webů sady Azure Pack Windows můžete při konfiguraci nové farmy přidat druhý kontroler webů.

1. Při výběru typu kontroleru vyberte Připojit server k existujícímu cloudu webů jako sekundární kontroler.
2. V seznamu systémových klíčů a připojovacích řetězců databáze klepněte na tlačítko Konfigurovat
3. V místním okně zadejte hodnoty pro tato pole:
   • Primární kontroler
   • Uživatelské jméno
   • Heslo
4. Kliknutím na tlačítko OK nakonfigurujte druhý kontroler.

Přidání druhého kontroleru webů do existující farmy

Pomocí následujících skriptů přidejte kontroler do existující farmy:

• OnStartSecondaryController.cmd – Nainstaluje instalační program WebPlatform (Web PI) na server Windows 2012 nebo virtuální počítač, který jste připravili. Potom volá skripty HostingBootstrapperBootstrapper a OnStartSecondaryController postupně za účelem dokončení zřizování sekundárního kontroleru. Mezi požadované parametry patří přihlašovací údaje pro správu SQL Server a správce kontroleru, které se použijí v nastavení.

• HostingBootstrapperBootstrapper.ps1 – Volá program Files\Microsoft\Web Platform Installer\WebpiCmd.exe k instalaci druhého kontroleru webů. Používá stejný postup jako při instalaci primárního kontroleru, ale zahodí konfigurační portál zadáním přepínače příkazového řádku /SuppressPostFinish.

• OnStartSecondaryController.ps1 – Zkopíruje konfigurační data z primárního kontroleru do sekundárního kontroleru, včetně SystemCore klíčů a SiteRuntime připojovacích řetězců pro hostování a měření prostředků. Po dokončení se spustí služba WebFarmService.

• Common.ps1 – poskytuje podpůrné funkce pro skript OnStartSecondaryController.ps1.

Postup spuštění skriptů

1. Zkopírujte soubory skriptu do složky na serveru, který bude sekundární kontroler.

2. Zkopírujte WebPlatformInstaller.msi soubor do stejné složky jako skripty. To je nezbytné, protože skript OnStartSecondaryController.cmd automatizuje instalaci webového PI.

3. Spusťte OnStartSecondaryController.cmd s právy správce a zadejte parametry popsané v následující tabulce. Jsou vyžadována oprávnění pro správu, aby bylo možné nainstalovat příslušné produkty prostřednictvím automatizace webových PI a k primárnímu řadiči je možné přistupovat přes WinRM.

   Poznámka

   Ve scénáři PRACOVNÍ SKUPINY možná budete muset povolit WinRM na primárním řadiči nebo spustit příkazy ve skriptu OnStartSecondaryController.cmd ručně.
