此方案涉及创建一个资源组、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。In this scenario you will create a resource group, two app service plans, two web apps, a traffic manager profile, and two traffic manager endpoints. 完成本练习后，会获得一个高可用性体系结构，它基于最低网络延迟提供 Web 应用的全局可用性。Once the exercise is complete you will have a high-available architecture which allows provides global availability of your web app based on the lowest network latency.

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。If needed, install the Azure PowerShell using the instruction found in the Azure PowerShell guide, and then run Connect-AzAccount -Environment AzureChinaCloud to create a connection with Azure.

示例脚本Sample script

# Generates a Random Value
$Random=(New-Guid).ToString().Substring(0,8)

# Variables
$ResourceGroupName="myResourceGroup$Random"
$App1Name="AppServiceTM1$Random"
$App2Name="AppServiceTM2$Random"
$Location1="ChinaEast"
$Location2="ChinaNorth"

# Create a Resource Group
New-AzResourceGroup -Name $ResourceGroupName -Location $Location1

# Create Traffic Manager Profile
New-AzTrafficManagerProfile -Name "$ResourceGroupName-tmp" -ResourceGroupName $ResourceGroupName -TrafficRoutingMethod Performance -MonitorPath '/' -MonitorProtocol "HTTP" -RelativeDnsName $ResourceGroupName -Ttl 30 -MonitorPort 80

# Create an App Service Plan
New-AzAppservicePlan -Name "$App1Name-Plan" -ResourceGroupName $ResourceGroupName -Location $Location1 -Tier Standard
New-AzAppservicePlan -Name "$App2Name-Plan" -ResourceGroupName $ResourceGroupName -Location $Location2 -Tier Standard

# Create a Web App in the App Service Plan
$App1ResourceId=(New-AzWebApp -Name $App1Name -ResourceGroupName $ResourceGroupName -Location $Location1 -AppServicePlan "$App1Name-Plan").Id
$App2ResourceId=(New-AzWebApp -Name $App2Name -ResourceGroupName $ResourceGroupName -Location $Location2 -AppServicePlan "$App2Name-Plan").Id

# Create Traffic Manager Endpoints for Web Apps
New-AzTrafficManagerEndpoint -Name "$App1Name-$Location1" -ResourceGroupName $ResourceGroupName -ProfileName "$ResourceGroupName-tmp" -Type AzureEndpoints -TargetResourceId $App1ResourceId -EndpointStatus "Enabled"
New-AzTrafficManagerEndpoint -Name "$App2Name-$Location2" -ResourceGroupName $ResourceGroupName -ProfileName "$ResourceGroupName-tmp" -Type AzureEndpoints -TargetResourceId $App2ResourceId -EndpointStatus "Enabled"

清理部署Clean up deployment

运行脚本示例后，可以使用以下命令删除资源组、Web 应用以及所有相关资源。After the script sample has been run, the following command can be used to remove the resource group, web app, and all related resources.

Remove-AzResourceGroup -Name myResourceGroup -Force

脚本说明Script explanation

此脚本使用以下命令。This script uses the following commands. 表中的每条命令均链接到特定于命令的文档。Each command in the table links to command specific documentation.
