为实现应用程序的高可用性路由流量 - Azure PowerShell

此脚本将创建一个资源组、两个应用服务计划、两个 Web 应用、一个流量管理器配置文件和两个流量管理器终结点。 流量管理器将流量引导到一个区域（作为主要区域）中的应用程序；主要区域中的应用程序不可用时，引导到次要区域。 执行脚本前，必须将 MyWebApp、MyWebAppL1 和 MyWebAppL2 值更改为 Azure 内的唯一值。 运行脚本后，可以使用 URL mywebapp.trafficmanager.cn 访问主要区域中的应用。

必要时，请使用 Azure PowerShell 指南中的说明安装 Azure PowerShell，并运行 Connect-AzAccount -Environment AzureChinaCloud 创建与 Azure 的连接。

如果没有 Azure 试用版订阅，请在开始前创建一个试用版订阅。

示例脚本

# Variables for common values
$rgName1="MyResourceGroup1"
$rgName2="MyResourceGroup2"
$location1="chinaeast"
$location2="chinaeast2"

# The values of the variables below must be unique (replace with your own names).
$webApp1="mywebapp$(Get-Random)"
$webApp2="mywebapp$(Get-Random)"
$webAppL1="MyWebAppL1"
$webAppL2="MyWebAppL2"

# Create a resource group in location one.
New-AzResourceGroup -Name $rgName1 -Location $location1

# Create a resource group in location two.
New-AzResourceGroup -Name $rgName2 -Location $location2

# Create a website deployed from GitHub in both regions (replace with your own GitHub URL).
$gitrepo="https://github.com/Azure-Samples/app-service-web-dotnet-get-started.git"

# Create a hosting plan and website and deploy it in location one (requires Standard 1 minimum SKU).

$appServicePlan = New-AzAppServicePlan -Name $webappl1 -ResourceGroupName $rgName1 `
  -Location $location1 -Tier Standard 

$web1 = New-AzWebApp -ResourceGroupName $rgname1 -Name $webApp1 -Location $location1 `
  -AppServicePlan $webappl1

# Configure GitHub deployment from your GitHub repo and deploy once.
$PropertiesObject = @{
    repoUrl = "$gitrepo";
    branch = "master";
    isManualIntegration = "true";
}

Set-AzResource -PropertyObject $PropertiesObject -ResourceGroupName $rgname1 `
-ResourceType Microsoft.Web/sites/sourcecontrols -ResourceName $webapp1/web `
-ApiVersion 2015-08-01 -Force

# Create a hosting plan and website and deploy it in location two (requires Standard 1 minimum SKU).

$appServicePlan = New-AzAppServicePlan -Name $webappl2 -ResourceGroupName $rgName2 `
  -Location $location2 -Tier Standard 

$web2 = New-AzWebApp -ResourceGroupName $rgname2 -Name $webApp2 `
  -Location $location2 -AppServicePlan $webappl2

$PropertiesObject = @{
    repoUrl = "$gitrepo";
    branch = "master";
    isManualIntegration = "true";
}

Set-AzResource -PropertyObject $PropertiesObject -ResourceGroupName $rgname2 `
  -ResourceType Microsoft.Web/sites/sourcecontrols -ResourceName $webapp2/web `
  -ApiVersion 2015-08-01 -Force

# Create a Traffic Manager profile.
$tm = New-AzTrafficManagerProfile -Name 'MyTrafficManagerProfile' -ResourceGroupName $rgname1 `
  -TrafficRoutingMethod Priority -RelativeDnsName $web1.SiteName -Ttl 60 `
  -MonitorProtocol HTTP -MonitorPort 80 -MonitorPath /

# Create an endpoint for the location one website deployment and set it as the priority target.
$endpoint = New-AzTrafficManagerEndpoint -Name 'MyEndPoint1' -ProfileName $tm.Name `
  -ResourceGroupName $rgname1 -Type AzureEndpoints -Priority 1 `
  -TargetResourceId $web1.Id -EndpointStatus Enabled

# Create an endpoint for the location two website deployment and set it as the secondary target.
$endpoint2 = New-AzTrafficManagerEndpoint -Name 'MyEndPoint2' -ProfileName $tm.Name `
  -ResourceGroupName $rgname1 -Type AzureEndpoints -Priority 2 `
  -TargetResourceId $web2.Id -EndpointStatus Enabled

运行以下命令来删除资源组、VM 和所有相关资源。

Remove-AzResourceGroup -Name myResourceGroup1
Remove-AzResourceGroup -Name myResourceGroup2
