使用 PowerShell 将数据库复制到新服务器
适用于:Azure SQL 数据库
以下 Azure PowerShell 脚本示例在新服务器的 Azure SQL 数据库中创建现有数据库的副本。
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 Az 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 -EnvironmentName AzureChinaCloud
以创建与 Azure 的连接。
将数据库复制到新服务器
# Connect-AzAccount -Environment AzureChinaCloud
# The SubscriptionId in which to create these objects
$SubscriptionId = ''
# Set the resource group name and location for your source server
$sourceResourceGroupName = "mySourceResourceGroup-$(Get-Random)"
$sourceResourceGroupLocation = "chinaeast"
# Set the resource group name and location for your target server
$targetResourceGroupname = "myTargetResourceGroup-$(Get-Random)"
$targetResourceGroupLocation = "chinanorth"
# Set an admin login and password for your server
$adminSqlLogin = "SqlAdmin"
$password = "ChangeYourAdminPassword1"
# The logical server names have to be unique in the system
$sourceServerName = "source-server-$(Get-Random)"
$targetServerName = "target-server-$(Get-Random)"
# The sample database name
$sourceDatabaseName = "mySampleDatabase"
$targetDatabaseName = "CopyOfMySampleDatabase"
# The ip address range that you want to allow to access your servers
$sourceStartIp = "0.0.0.0"
$sourceEndIp = "0.0.0.0"
$targetStartIp = "0.0.0.0"
$targetEndIp = "0.0.0.0"
# Set subscription
Set-AzContext -SubscriptionId $subscriptionId
# Create two new resource groups
$sourceResourceGroup = New-AzResourceGroup -Name $sourceResourceGroupName -Location $sourceResourceGroupLocation
$targetResourceGroup = New-AzResourceGroup -Name $targetResourceGroupname -Location $targetResourceGroupLocation
# Create a server with a system wide unique server name
$sourceResourceGroup = New-AzSqlServer -ResourceGroupName $sourceResourceGroupName `
-ServerName $sourceServerName `
-Location $sourceResourceGroupLocation `
-SqlAdministratorCredentials $(New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $adminSqlLogin, $(ConvertTo-SecureString -String $password -AsPlainText -Force))
$targetResourceGroup = New-AzSqlServer -ResourceGroupName $targetResourceGroupname `
-ServerName $targetServerName `
-Location $targetResourceGroupLocation `
-SqlAdministratorCredentials $(New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $adminSqlLogin, $(ConvertTo-SecureString -String $password -AsPlainText -Force))
# Create a server firewall rule that allows access from the specified IP range
$sourceServerFirewallRule = New-AzSqlServerFirewallRule -ResourceGroupName $sourceResourceGroupName `
-ServerName $sourceServerName `
-FirewallRuleName "AllowedIPs" -StartIpAddress $sourcestartip -EndIpAddress $sourceEndIp
$targetServerFirewallRule = New-AzSqlServerFirewallRule -ResourceGroupName $targetResourceGroupname `
-ServerName $targetServerName `
-FirewallRuleName "AllowedIPs" -StartIpAddress $targetStartIp -EndIpAddress $targetEndIp
# Create a blank database in the source-server with an S0 performance level
$sourceDatabase = New-AzSqlDatabase -ResourceGroupName $sourceResourceGroupName `
-ServerName $sourceServerName `
-DatabaseName $sourceDatabaseName -RequestedServiceObjectiveName "S0"
# Copy source database to the target server
$databaseCopy = New-AzSqlDatabaseCopy -ResourceGroupName $sourceResourceGroupName `
-ServerName $sourceServerName `
-DatabaseName $sourceDatabaseName `
-CopyResourceGroupName $targetResourceGroupname `
-CopyServerName $targetServerName `
-CopyDatabaseName $targetDatabaseName
# Clean up deployment
# Remove-AzResourceGroup -ResourceGroupName $sourceResourceGroupName
# Remove-AzResourceGroup -ResourceGroupName $targetResourceGroupname
清理部署
使用以下命令删除资源组及其相关的所有资源。
Remove-AzResourceGroup -ResourceGroupName $sourceresourcegroupname
Remove-AzResourceGroup -ResourceGroupName $targetresourcegroupname
脚本说明
此脚本使用以下命令。 表中的每条命令均链接到特定于命令的文档。
命令 | 注释 |
---|---|
New-AzResourceGroup | 创建用于存储所有资源的资源组。 |
New-AzSqlServer | 创建托管数据库和弹性池的服务器。 |
New-AzSqlDatabase | 创建数据库或弹性池。 |
New-AzSqlDatabaseCopy | 创建当前使用快照的数据库副本。 |
Remove-AzResourceGroup | 删除资源组,包括所有嵌套的资源。 |
