使用 PowerShell 将托管实例添加到故障转移组

  • 项目

适用于：Azure SQL 托管实例

此 PowerShell 脚本示例创建两个托管实例，将其添加到故障转移组，然后测试从主托管实例到辅助托管实例的故障转移。

如果没有 Azure 试用版订阅，请在开始前创建一个试用版订阅。

注意

本文使用 Azure Az PowerShell 模块，这是与 Azure 交互时推荐使用的 PowerShell 模块。 若要开始使用 Az PowerShell 模块，请参阅安装 Azure PowerShell。 若要了解如何迁移到 Az PowerShell 模块，请参阅 将 Azure PowerShell 从 AzureRM 迁移到 Az。

本教程需要 Azure PowerShell 1.4.0 或更高版本。 如果需要进行升级，请参阅 Install Azure PowerShell module（安装 Azure PowerShell 模块）。 此外，还需要运行 Connect-AzAccount -Environment AzureChinaCloud 以创建与 Azure 的连接。

设置订阅和创建资源组

# Suppress networking breaking changes warning (https://aka.ms/azps-changewarnings)
Set-Item Env:\SuppressAzurePowerShellBreakingChangeWarnings "true"

# Set the subscription context
Set-AzContext -SubscriptionId $subscriptionId 

# Create the resource group
Write-host "Creating resource group..."
$resourceGroup = New-AzResourceGroup -Name $resourceGroupName -Location $location -Tag @{Owner="SQLDB-Samples"}
$resourceGroup
命令 说明
1. Connect-AzAccount 连接到 Azure。
2. Set-AzContext 设置订阅上下文。
3. New-AzResourceGroup 创建 Azure 资源组。

配置虚拟网络对等

在托管主实例和辅助托管实例的虚拟网络之间创建全局虚拟网络对等互连：

# Create global virtual network peering
$primaryVirtualNetwork  = Get-AzVirtualNetwork `
                  -Name $primaryVNet `
                  -ResourceGroupName $resourceGroupName

创建故障转移组

创建故障转移组：

# Create failover group
Write-host "Creating the failover group..."
$failoverGroup = New-AzSqlDatabaseInstanceFailoverGroup -Name $failoverGroupName `
     -Location $location -ResourceGroupName $resourceGroupName -PrimaryManagedInstanceName $primaryInstance `
     -PartnerRegion $drLocation -PartnerManagedInstanceName $secondaryInstance `
     -FailoverPolicy Manual -GracePeriodWithDataLossHours 1
$failoverGroup
命令 注释
New-AzSqlDatabaseInstanceFailoverGroup 创建新的 Azure SQL 托管实例故障转移组。

测试计划的故障转移

通过故障转移到辅助副本，然后故障回复来测试计划的故障转移。

命令 说明
1. Get-AzSqlDatabaseInstanceFailoverGroup 获取或列出 SQL 托管实例故障转移组。
2. Switch-AzSqlDatabaseInstanceFailoverGroup 执行 SQL 托管实例故障转移组的故障转移。

验证每个服务器的角色

使用 Get-AzSqlDatabaseInstanceFailoverGroup 命令确认每个服务器的角色：

# Verify the current primary role
Get-AzSqlDatabaseInstanceFailoverGroup -ResourceGroupName $resourceGroupName `
    -Location $location -Name $failoverGroupName

故障转移到辅助服务器

使用 Switch-AzSqlDatabaseInstanceFailoverGroup 故障转移到辅助服务器。

# Failover the primary managed instance to the secondary role
Write-host "Failing primary over to the secondary location"
Get-AzSqlDatabaseInstanceFailoverGroup -ResourceGroupName $resourceGroupName `
    -Location $drLocation -Name $failoverGroupName | Switch-AzSqlDatabaseInstanceFailoverGroup
Write-host "Successfully failed failover group to secondary location"

# Verify the current primary role
Get-AzSqlDatabaseInstanceFailoverGroup -ResourceGroupName $resourceGroupName `
    -Location $drLocation -Name $failoverGroupName

将故障转移组还原到主服务器

使用 Switch-AzSqlDatabaseInstanceFailoverGroup 命令故障回复到主服务器。

# Fail primary managed instance back to primary role
Write-host "Failing primary back to primary role"
Get-AzSqlDatabaseInstanceFailoverGroup -ResourceGroupName $resourceGroupName `
    -Location $location -Name $failoverGroupName | Switch-AzSqlDatabaseInstanceFailoverGroup
Write-host "Successfully failed failover group to primary location"

# Verify the current primary role
Get-AzSqlDatabaseInstanceFailoverGroup -ResourceGroupName $resourceGroupName `
    -Location $location -Name $failoverGroupName

清理部署

使用以下命令删除资源组及其相关的所有资源。 需要删除资源组两次。 第一次删除资源组将删除托管实例和虚拟群集，但随后会失败，并显示错误消息 Remove-AzResourceGroup : Long running operation failed with status 'Conflict'。 再次运行 Remove-AzResourceGroup 命令，删除所有残留资源以及资源组。

Remove-AzResourceGroup -ResourceGroupName $resourceGroupName

完整脚本

以下代码片段是完整的脚本：

# Add SQL Managed Instance to a failover group

<#
Due to SQL Managed Instance deployment times, plan for a full day to complete the entire script. 
You can monitor deployment progress in the activity log within the Azure portal.  

For more information on deployment times, see https://docs.azure.cn/azure-sql/managed-instance/management-operations-overview. 

Closing the session will result in an incomplete deployment. To continue progress, you will
need to determine what the random modifier is and manually replace the random variable with 
the previously-assigned value.
