Provisionar um segundo controlador de Sites
Aplica-se a: Windows Azure Pack
Microsoft Azure Pack: Os Sites podem ter um máximo de dois Controladores de Sites. Para a alta disponibilidade, é altamente recomendável que você exercita essa máxima e provisione um segundo Controlador de Sites. Você pode fazer isso de duas maneiras:
- Quando você cria um novo farm
- Adicionar um controlador a um farm existente
Adicionar um segundo controlador de Sites a um novo farm (com a versão de atualização 6 e posterior)
Usando o Windows console de gerenciamento de Sites do Azure Pack, você pode adicionar um segundo controlador de Sites ao configurar um novo farm.
- Ao selecionar o tipo de controlador, selecione Ingressar servidor em uma nuvem de Sites existente como controlador secundário.
- Na lista de Chaves do Sistema e ConnectionStrings de Banco de Dados, clique em Configurar
- Na janela pop-up, insira valores para estes campos:
- Controlador primário
- Nome de usuário
- Senha
- Clique em OK para configurar o segundo controlador.
Adicionar um segundo controlador de Sites a um farm existente
Use os seguintes scripts para adicionar um controlador a um farm existente:
OnStartSecondaryController.cmd - Instala o WebPlatform Installer (Web PI) no servidor do Windows 2012 ou na Máquina Virtual que você preparou. Depois, ele chama os scripts HostingBootstrapperBootstrapper e OnStartSecondaryController sucessivamente para concluir o provisionamento do controlador secundário. Os parâmetros necessários incluem as credenciais administrativas do SQL Server e do Controlador que serão usadas em sua configuração.
HostingBootstrapperBootstrapper.ps1 - Chama Arquivos de Programas\Microsoft\Web Platform Installer\WebpiCmd.exe para instalar o segundo controlador de Sites. Ele usa o mesmo procedimento da instalação do controlador primário, mas descarta o portal de configuração especificando a opção de linha de comando/SuppressPostFinish.
OnStartSecondaryController.ps1 - Copia dados de configuração do controlador primário para o controlador secundário, inclusive as chaves
SystemCoreeSiteRuntimee as cadeias de conexão de medição de recursos e hospedagem. Ao terminar, ele inicia o WebFarmService.Common.ps1 - Fornece funções de suporte para o script OnStartSecondaryController.ps1.
Importante
Esses scripts exigem que o Windows Remote Management (WinRM) seja habilitado no controlador primário.
Etapas para executar os scripts
Copie os arquivos de script em uma pasta no servidor que será o controlador secundário.
Copie o arquivo WebPlatformInstaller.msi na mesma pasta que os scripts. Isso é necessário porque o script OnStartSecondaryController.cmd automatiza a instalação do Web PI.
Execute OnStartSecondaryController.cmd com direitos de administrador, fornecendo os parâmetros descritos na tabela abaixo. Os privilégios administrativos são necessários para que os produtos adequados possam ser instalados através da automação de Web PI e o controlador primário possa ser acessado através de WinRM.
Observação
Em um cenário de WORKGROUP, talvez você precise habilitar WinRM no controlador primário, ou executar manualmente os comandos do script OnStartSecondaryController.cmd.
OnStartSecondaryController.cmd
Sintaxe
OnStartSecondaryController.cmd -feed %Feed% -webSitesInstanceName %WebSitesInstanceName% -sqlservername %DatabaseServerName% -sqlsysadmin %DatabaseSysAdminAccount% -sqlsysadminpwd %DatabaseSysAdminPassword% -controllerAdminUserName %ControllerAdminUserName% -controllerAdminPassword %ControllerAdminPassword%
Parâmetros
| Nome do parâmetro | Descrição | Observações |
feed |
Opcionalmente, especifica o feed de Web PI que será usado para instalar o controlador. | Se esse parâmetro não for especificado, o feed primário do Web PI padrão será usado. |
webSitesInstanceName |
Usado como prefixo de objetos do banco de dados | Deve corresponder ao nome de prefixo do banco de dados na instalação. |
sqlservername |
Nome da instância do SQL Server. | |
sqlsysadmin |
Nome de conta do usuário administrador de sistema do SQL Server. | Precisa ser membro de funções de servidor sysadmin. |
sqlsysadminpwd |
Senha de conta do usuário administrador de sistema do SQL Server. | |
controllerAdminUserName |
Nome da conta de Administrador de Web Farm Framework (WFF) a ser provisionada | Se essa for uma conta de domínio, ele será adicionada ao grupo de administradores locais. Se o servidor estiver em WORKGROUP, ele tentará criar o usuário, caso esse usuário não exista, e o adicionará ao grupo de administradores locais. |
controllerAdminPassword |
Senha da conta do Administrador WFF a ser provisionada |
