Fornecimento de um Segundo Controlador de Sites Web

Aplica-se a: Windows Azure Pack

Windows Azure Pack: Os Web Sites podem ter um máximo de dois Controladores de Web Sites. Para alta disponibilidade, recomenda-se vivamente que exerça este máximo e provisão de um segundo Controlador de Web Sites. Pode fazer isto de duas maneiras:

• Quando se cria uma nova quinta
• Adicione um controlador a uma fazenda existente

Adicione um segundo controlador de Web Sites a uma nova fazenda (com o Update Release 6 e mais tarde)

Utilizando a consola de gestão de Web Sites Azure Pack Windows, pode adicionar um segundo controlador de Web Sites quando configurar uma nova quinta.

1. Ao selecionar o tipo de controlador, selecione Juntar o servidor a uma nuvem de Websites existente como controlador secundário.
2. Na lista de Chaves do Sistema e Ligação de Bases de Dados, clique em Configurar
3. Na janela popup, introduza valores para estes campos:
   • Controlador Primário
   • Nome de utilizador
   • Palavra-passe
4. Clique em OK para configurar o segundo controlador.

Adicione um segundo controlador de Web Sites a uma fazenda existente

Utilize os seguintes scripts para adicionar um controlador a uma quinta existente:

• OnStartSecondaryController.cmd - Instala o Instalador webPlatform (Web PI) no servidor Windows 2012 ou máquina virtual que preparou. Em seguida, chama os scripts HostingBootstrapperBootstrapper e OnStartSecondaryController sucessivamente para completar o provisionamento do controlador secundário. Os parâmetros necessários incluem as credenciais administrativas SQL Server e controlador que serão usadas na sua configuração.

• HostingBootstrapperBootstrapper.ps1 - Chama ficheiros de programas\Microsoft\Web Platform Installer\WebpiCmd.exe instalar o segundo Controlador de Web Sites. Utiliza o mesmo procedimento que quando instala o controlador primário, mas descarta o portal de configuração especificando o interruptor da linha de comando /SupressOrFinish.

• OnStartSecondaryController.ps1 - Copia os dados de configuração do controlador primário para o controlador secundário, incluindo as SystemCore teclas e SiteRuntime as cordas de ligação de alojamento e medição de recursos. Quando termina, inicia o WebFarmService.

• Common.ps1 - Fornece funções de suporte para o script OnStartSecondaryController.ps1.

Passos para executar os scripts

1. Copie os ficheiros de script para uma pasta no servidor que será o Controlador Secundário.

2. Copie o ficheiro WebPlatformInstaller.msi para a mesma pasta que os scripts. Isto é necessário porque o script OnStartSecondaryController.cmd automatiza a instalação de WEB PI.

3. Executar OnStartSecondaryController.cmd com direitos de administrador, fornecendo os parâmetros descritos na tabela abaixo. São necessários privilégios administrativos para que os produtos apropriados possam ser instalados através da automatização Web PI e o controlador primário possa ser acedido através do WinRM.

   Nota

   Num cenário de WORKGROUP, poderá ser necessário ativar o WinRM no controlador primário ou executar os comandos no script OnStartSecondaryController.cmd manualmente.
