Azure Application Gateway (4) 设置URL路由

　　《Windows Azure Platform 系列文章目录》

　　本文将介绍如果使用Azure PowerShell，创建Azure Application Gateway URL Routing

　　请读者在使用之前，请先查看笔者之前的文章：Azure Application Gateway (3) 设置URL路由，熟悉相关的内容

　　注意：Azure Application Gateway必须在ARM模式下才可以创建。

　　另外PowerShell模式下，和Portal创建的不一样。

　　PowerShell模式，并不需要先创建81端口，再创建80端口。PowerShell直接可以使用80端口设置URL Routing

#在弹出窗口登录
Login-AzureRmAccount -EnvironmentName AzureChinaCloud

#选择订阅信息
Select-AzureRmSubscription -SubscriptionName "Training"

#先手动创建Resource Group，这里设置Resource Group
$resourcegroupname = 'LeiAppGWRG'

#手动创建Virtual Network
#同之前的文档一样，这个Virtual Network必须要有2个Subnet
$virtualnetworkname= 'LeiAppGatewayVNet'

#设置Application Gateway名称
$appgatewayname = 'LeiAppGateway'

#设置Application Gateway公网IP地址
$publicipname = 'LeiAppGatewayPublicIP'

#Application Gateway 所在的数据中心
$location= 'China East'

#设置端口号
$port=80

$vnet=Get-AzureRmVirtualNetwork -name $virtualnetworkname -ResourceGroupName $resourcegroupname

#Application Gateway加入到第2个Subnet里
$subnet=$vnet.Subnets[1]

$publicip = New-AzureRmPublicIpAddress -ResourceGroupName $resourcegroupname -name $publicipname -location $location -AllocationMethod Dynamic

#Create Application Gateway
$gipconfig = New-AzureRmApplicationGatewayIPConfiguration -Name LeiAppGatewayPublicIP -Subnet $subnet

#设置Backend Pool 1
$pool1 = New-AzureRmApplicationGatewayBackendAddressPool -Name imagesBackendPool -BackendIPAddresses 10.0.0.4,10.0.0.5

#设置Backend Pool 2
$pool2 = New-AzureRmApplicationGatewayBackendAddressPool -Name videosBackendPool -BackendIPAddresses 10.0.0.11,10.0.0.12

#设置Backend Pool 1的会话保持，不保持会话
$poolSetting01 = New-AzureRmApplicationGatewayBackendHttpSettings -Name "imagesSetting" -Port $port -Protocol Http -CookieBasedAffinity Disabled -RequestTimeout 120

#设置Backend Pool 2的会话保持，为保持会话
$poolSetting02 = New-AzureRmApplicationGatewayBackendHttpSettings -Name "videosSetting" -Port $port -Protocol Http -CookieBasedAffinity Enabled -RequestTimeout 240

$fipconfig01 = New-AzureRmApplicationGatewayFrontendIPConfig -Name "frontend1" -PublicIPAddress $publicip

#设置URL Route，为/images/*
$imagePathRule = New-AzureRmApplicationGatewayPathRuleConfig -Name "pathrule1" -Paths "/images/*" -BackendAddressPool $pool1 -BackendHttpSettings $poolSetting01

#设置URL Route，为/videos/*
$videoPathRule = New-AzureRmApplicationGatewayPathRuleConfig -Name "pathrule2" -Paths "/videos/*" -BackendAddressPool $pool2 -BackendHttpSettings $poolSetting02

#设置DefaultBackendAddressPool
$urlPathMap = New-AzureRmApplicationGatewayUrlPathMapConfig -Name "urlpathmap" -PathRules $videoPathRule, $imagePathRule -DefaultBackendAddressPool $pool1 -DefaultBackendHttpSettings $poolSetting02

$rule01 = New-AzureRmApplicationGatewayRequestRoutingRule -Name "rule1" -RuleType PathBasedRouting -HttpListener $listener -UrlPathMap $urlPathMap

#设置Application Gateway Size为Small，实例个数为1个
$sku = New-AzureRmApplicationGatewaySku -Name "Standard_Small" -Tier Standard -Capacity 1

#开始创建Application Gateway
