Azure-ILB配置

说明

Azure对内部的ILB配置介绍很粗略，在配置过程中必定会碰到一大堆的问题，总的来说配置过程需要通过微软的powshell配置，每个人的程度不同，并不适用于大部分用户。
现对配置过程稍作介绍。
前提：

登陆中国版Azure管理门户（https://manage.windowsazure.cn）
正常登陆中国版Azure管理门户后，在IE浏览器中新打开一个选项卡输入此地址（https://manage.windowsazure.cn/publishsettings/index?client=powershell）按回车键，下载PublishSettingsFile文件到本地
打开Windows Azure PowerShell执行Import-AzurePublishSettingsFile ‘**.publishsettings’，将刚才下载的文件导入。我这里导入了两个账户，需要选择默认订阅。

PS C:> Get-AzureSubscription
SubscriptionId : xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx1
SubscriptionName : Windows Azure Enterprise Trial(Converted to EA)
Environment : AzureChinaCloud
SupportedModes : AzureServiceManagement
DefaultAccount : 39ADA911695E3937B7FCAEA99763CD824419FE9
Accounts : {39ADA911695E3937B7FCAEEA9763CD824419FE9}

选择默认订阅

PS C:\> Select-AzureSubscription -SubscriptionName “Windows Azure 企业” –Default
警告: Current and Default parameters have been deprecated. Select-AzureSubscription will always update the Default
Subscription.

对于现有云服务或在区域虚拟网络下部署的云服务，可以使用以下 Windows PowerShell 命令创建 ILB 实例：

$svc=”<Cloud Service Name>”
$ilb=”<Name of your ILB instance>”
$subnet=”<Name of the subnet within your virtual network-optional>”
$IP=”<The IPv4 address to use on the subnet-optional>”
Add-AzureInternalLoadBalancer -ServiceName $svc -InternalLoadBalancerName $ilb –SubnetName $subnet –StaticVNetIPAddress $IP

配置:

PS C:\> $svc=”zz-cloud”
PS C:\> $ilb=”percona-ilb”
PS C:\> $subnet=”Subnet-1″
PS C:\> $IP=”10.0.0.101″
PS C:\> Add-AzureInternalLoadBalancer -ServiceName $svc -InternalLoadBalancerName $ilb –SubnetName $subnet –StaticVNetI
Address $IP
详细信息: 10:44:58 – Begin Operation: Add-AzureInternalLoadBalancer
详细信息: 10:45:36 – Completed Operation: Add-AzureInternalLoadBalancer

OperationDescription OperationId OperationStatus
——————– ———– —————
Add-AzureInternalLoadBalancer 11039dad-2785-4109-90d0-64801c998a48 Succeeded

对于现有虚拟机，可以使用以下命令将终结点添加到 ILB 实例

$svc=”<Cloud service name>”
$vmname=”<Name of the VM>”
$epname=”<Name of the endpoint>”
$prot=”tcp” or “udp”
$locport=<local port number>
$pubport=<public port number>
$ilb=”<Name of your ILB instance>”
Get-AzureVM –ServiceName $svc –Name $vmname | Add-AzureEndpoint -Name $epname -Protocol $prot -LocalPort $locport -PublicPort $pubport –DefaultProbe -InternalLoadBalancerName $ilb | Update-AzureVM

配置：

PS C:\> $svc=”zz-cloud”
PS C:\> $vmname=”vanelife-db1″
PS C:\> $epname=”mysql1″
PS C:\> $prot=”tcp”
PS C:\> $locport=3306
PS C:\> $pubport=3306
PS C:\> $ilb=”percona-ilb”
PS C:\> Get-AzureVM –ServiceName $svc –Name $vmname | Add-AzureEndpoint -Name $epname -Protocol $prot -LocalPort $locpo
t -PublicPort $pubport –DefaultProbe -InternalLoadBalancerName $ilb | Update-AzureVM

位于命令管道位置 2 的 cmdlet Add-AzureEndpoint

#如果你在创建 ILB 实例的过程中指定了 IP 地址，则你已有 VIP。否则，你可以使用以下命令查看 VIP：

1 2	$svc=”<Cloud Service Name>” Get-AzureService -ServiceName $svc \| Get-AzureInternalLoadBalancer

PS C:\> Get-AzureService -ServiceName $svc | Get-AzureInternalLoadBalancer
详细信息: 10:48:36 – Begin Operation: Get-AzureService
详细信息: 10:48:37 – Completed Operation: Get-AzureService
详细信息: 10:48:38 – Begin Operation: Get-AzureInternalLoadBalancer
详细信息: 10:48:39 – Completed Operation: Get-AzureInternalLoadBalancer
InternalLoadBalancerName : percona-ilb
ServiceName : zz-cloud
DeploymentName : vanelife-App1
SubnetName : Subnet-1
IPAddress : 10.0.0.101
OperationDescription : Get-AzureInternalLoadBalancer
OperationId : 455eb594-d19b-4fc7-91d8-e14fac70cda
OperationStatus : Succeeded

这样内部的LB就配置完成了，VIP地址是10.0.0.101，负载均衡到Subnet-1的vanelife-db1，vanelife-db2，vanelife-db3的3台服务器上。
