Manage Azure Cache for Redis with Azure PowerShell

  • Artikkeli

This article shows you how to create, update, and scale your Azure Cache for Redis instances. The article also shows how to regenerate access keys, and how to view information about your caches. For a complete list of Azure Cache for Redis PowerShell cmdlets, see Azure Cache for Redis cmdlets.

Note

Azure has two different deployment models you can use to create and work with resources: Azure Resource Manager and classic. This article covers the use of the Resource Manager deployment model. We recommend the Resource Manager deployment model for new deployments instead of the classic deployment model.

For more information about the classic deployment model, see Azure Resource Manager vs. classic deployment: Understand deployment models and the state of your resources.

Prerequisites

If you have already installed Azure PowerShell, you must have Azure PowerShell version 1.0.0 or later. You can check the version of Azure PowerShell with this command at the Azure PowerShell command prompt.

    Get-Module Az | format-table version

First, you must sign in to Azure with this command.

    Connect-AzAccount

Specify the email address of your Azure account and your password in the Microsoft Azure sign-in dialog.

Next, if you have multiple Azure subscriptions, you need to set your Azure subscription. To see a list of your current subscriptions, run this command.

    Get-AzSubscription | sort SubscriptionName | Select SubscriptionName

To specify the subscription, run the following command. In the following example, the subscription name is ContosoSubscription.

    Select-AzSubscription -SubscriptionName ContosoSubscription

Before you can use Windows PowerShell with Azure Resource Manager, you need verify your set-up:

  • Windows PowerShell, Version 3.0 or 4.0. To find the version of Windows PowerShell, type:$PSVersionTable and verify the value of PSVersion is 3.0 or 4.0. To install a compatible version, see Windows Management Framework 3.0.

To get detailed help for any cmdlet you see in this tutorial, use the Get-Help cmdlet.

    Get-Help <cmdlet-name> -Detailed

For example, to get help for the New-AzRedisCache cmdlet, type:

    Get-Help New-AzRedisCache -Detailed

How to connect to other clouds

By default the Azure environment is AzureCloud, which represents the global Azure cloud instance. To connect to a different instance, use the Connect-AzAccount command with the -Environment or -EnvironmentName command-line switch with the environment or environment name you want.

To see the list of available environments, run the Get-AzEnvironment cmdlet.

To connect to the Azure Government Cloud

To connect to the Azure Government Cloud, use one of the following commands.

    Connect-AzAccount -EnvironmentName AzureUSGovernment

Or

    Connect-AzAccount -Environment (Get-AzEnvironment -Name AzureUSGovernment)

To create a cache in the Azure Government Cloud, use one of the following locations.

  • USGov Virginia
  • USGov Iowa

For more information about the Azure Government Cloud, see Microsoft Azure Government and Microsoft Azure Government Developer Guide.

To connect to the Microsoft Azure operated by 21Vianet Cloud

To connect to the Azure operated by 21Vianet cloud, use one of the following commands.

    Connect-AzAccount -EnvironmentName AzureChinaCloud

Or

    Connect-AzAccount -Environment (Get-AzEnvironment -Name AzureChinaCloud)

To create a cache in the Azure operated by 21Vianet Cloud, use one of the following locations.

To create an Azure Cache for Redis

New Azure Cache for Redis instances are created using the New-AzRedisCache cmdlet.

Important

The first time you create an Azure Cache for Redis in a subscription using the Azure portal, the portal registers the Microsoft.Cache namespace for that subscription. If you attempt to create the first Azure Cache for Redis in a subscription using PowerShell, you must first register that namespace using the following command; otherwise cmdlets such as New-AzRedisCache and Get-AzRedisCache fail.

Register-AzResourceProvider -ProviderNamespace "Microsoft.Cache"

To see a list of available parameters and their descriptions for New-AzRedisCache, run the following command.

        -Subnet <String>
            Required when deploying an Azure Cache for Redis inside an existing Azure Virtual Network.

        -StaticIP <String>
            Required when deploying an Azure Cache for Redis inside an existing Azure Virtual Network.

        <CommonParameters>
            This cmdlet supports the common parameters: Verbose, Debug,
            ErrorAction, ErrorVariable, WarningAction, WarningVariable,
            OutBuffer, PipelineVariable, and OutVariable. For more information, see
            about_CommonParameters (https://go.microsoft.com/fwlink/?LinkID=113216).

To create a cache with default parameters, run the following command.

    New-AzRedisCache -ResourceGroupName myGroup -Name mycache -Location "North Central US"

ResourceGroupName, Name, and Location are required parameters, but the rests are optional and have default values. Running the previous command creates a Standard SKU Azure Cache for Redis instance with the specified name, location, and resource group. The instance is 1 GB in size with the non-SSL port disabled.

To create a premium cache, specify a size of P1 (6 GB - 60 GB), P2 (13 GB - 130 GB), P3 (26 GB - 260 GB), or P4 (53 GB - 530 GB). To enable clustering, specify a shard count using the ShardCount parameter. The following example creates a P1 premium cache with three shards. A P1 premium cache is 6 GB in size, and since we specified three shards the total size is 18 GB (3 x 6 GB).

    New-AzRedisCache -ResourceGroupName myGroup -Name mycache -Location "North Central US" -Sku Premium -Size P1 -ShardCount 3

To specify values for the RedisConfiguration parameter, enclose the values inside {} as key/value pairs like @{"maxmemory-policy" = "allkeys-random", "notify-keyspace-events" = "KEA"}. The following example creates a standard 1-GB cache with allkeys-random maxmemory policy and keyspace notifications configured with KEA. For more information, see Keyspace notifications (advanced settings) and Memory policies.

    New-AzRedisCache -ResourceGroupName myGroup -Name mycache -Location "North Central US" -RedisConfiguration @{"maxmemory-policy" = "allkeys-random", "notify-keyspace-events" = "KEA"}

To configure the databases setting during cache creation

The databases setting can be configured only during cache creation. The following example creates a premium P3 (26 GB) cache with 48 databases using the New-AzRedisCache cmdlet.

    New-AzRedisCache -ResourceGroupName myGroup -Name mycache -Location "North Central US" -Sku Premium -Size P3 -RedisConfiguration @{"databases" = "48"}

For more information on the databases property, see Default Azure Cache for Redis server configuration. For more information on creating a cache using the New-AzRedisCache cmdlet, see the previous To create an Azure Cache for Redis section.

            ErrorAction, ErrorVariable, WarningAction, WarningVariable,
            OutBuffer, PipelineVariable, and OutVariable. For more information, see
            about_CommonParameters (https://go.microsoft.com/fwlink/?LinkID=113216).

The Set-AzRedisCache cmdlet can be used to update properties such as Size, Sku, EnableNonSslPort, and the RedisConfiguration values.

The following command updates the maxmemory-policy for the Azure Cache for Redis named myCache.

    Set-AzRedisCache -ResourceGroupName "myGroup" -Name "myCache" -RedisConfiguration @{"maxmemory-policy" = "allkeys-random"}

To scale an Azure Cache for Redis

Set-AzRedisCache can be used to scale an Azure Cache for Redis instance when the Size, Sku, or ShardCount properties are modified.

Note

Scaling a cache using PowerShell is subject to the same limits and guidelines as scaling a cache from the Azure portal. You can scale to a different pricing tier with the following restrictions.

  • You can't scale from a higher pricing tier to a lower pricing tier.
  • You can't scale from a Premium cache down to a Standard or a Basic cache.
  • You can't scale from a Standard cache down to a Basic cache.
  • You can scale from a Basic cache to a Standard cache but you can't change the size at the same time. If you need a different size, you can do a subsequent scaling operation to the desired size.
  • You can't scale from a Basic cache directly to a Premium cache. You must scale from Basic to Standard in one scaling operation, and then from Standard to Premium in a subsequent scaling operation.
  • You can't scale from a larger size down to the C0 (250 MB) size.

For more information, see How to Scale Azure Cache for Redis.

The following example shows how to scale a cache named myCache to a 2.5-GB cache. This command works for both a Basic or a Standard cache.

    Set-AzRedisCache -ResourceGroupName myGroup -Name myCache -Size 2.5GB

After this command is issued, the status of the cache is returned---similar to calling Get-AzRedisCache. The ProvisioningState is set to Scaling.

    PS C:\> Set-AzRedisCache -Name myCache -ResourceGroupName myGroup -Size 2.5GB


    Name               : mycache
    Id                 : /subscriptions/12ad12bd-abdc-2231-a2ed-a2b8b246bbad4/resourceGroups/mygroup/providers/Mi
                         crosoft.Cache/Redis/mycache
    Location           : South Central US
    Type               : Microsoft.Cache/Redis
    HostName           : mycache.redis.cache.windows.net
    Port               : 6379
    ProvisioningState  : Scaling
    SslPort            : 6380
    RedisConfiguration : {[maxmemory-policy, volatile-lru], [maxmemory-reserved, 150], [notify-keyspace-events, KEA],
                         [maxmemory-delta, 150]...}
    EnableNonSslPort   : False
    RedisVersion       : 3.0
    Size               : 1GB
    Sku                : Standard
    ResourceGroupName  : mygroup
    PrimaryKey         : ....
    SecondaryKey       : ....
    VirtualNetwork     :
    Subnet             :
    StaticIP           :
    TenantSettings     : {}
    ShardCount         :

When the scaling operation is complete, the ProvisioningState changes to Succeeded. If you need to make another scaling operation---for example, changing from Basic to Standard and then changing the size---you must wait until the previous operation is complete or you receive an error similar to the following.

    Set-AzRedisCache : Conflict: The resource '...' is not in a stable state, and is currently unable to accept the update request.
