移动和重命名 AppFabric 配置数据库

Question

最近我们对 AppFabric 配置数据库进行了迁移和重命名。

重命名从默认名称“AppFabricConfigurationDatabase”改为“AppFabricPreOrdersConfiguration”

DisirbutedCacheService.exe.config 已更改为新的数据库和服务器名称

<clusterConfig provider="System.Data.SqlClient" connectionString="Data Source=NEWSERVER;Initial Catalog=AppFabricPreOrdersConfiguration;Integrated Security=True" />

服务启动成功。

但从此时起，“缓存管理 powershell”不再启动，因为当调用 use-cachecluster 时，它仍会尝试连接到旧服务器/数据库。

ConnectionString 数据源=OLDSERVER 的测试连接失败；初始目录 =AppFabricCacheConfigurationDatabase;

Use-CacheCluster : ErrorCode:SubStatus:Invalid provider and c 连接字符串读取。

powershell 从哪里读取这些值？显然不是来自服务的配置文件，而是来自哪里？

Answer 1

由于我无法停止集群，我试图查看连接字符串是否会在不重新启动的情况下更改，并且基本上只是调用 Remove-CacheAdmin 和 Add-CacheAdmin....它成功了！ 当然，脚本必须在每台主机上运行，​​因此不适合大型设置，但显然不需要重新启动

param ([string] $provider, [string] $newConnectionString)

function Main {

    if ( (! $provider) -or (! $newConnectionString))
    {
        Write-Host "Usage: ChangeConnString.ps1 <provider> <newConnectionString>"
        exit(1)
    }

    Import-Module "DistributedCacheAdministration"
    Import-Module "DistributedCacheConfiguration"
    [Reflection.Assembly]::LoadWithPartialName('Microsoft.ApplicationServer.Caching.Management') | Out-Null
    [Reflection.Assembly]::LoadWithPartialName('System.Management.Automation') | Out-Null
    [Reflection.Assembly]::LoadWithPartialName('System.Management.Automation.Runspaces') | Out-Null

    Remove-CacheAdmin
    Add-CacheAdmin -Provider $provider -ConnectionString $newConnectionString  

}

Answer 2

其他用户提供的脚本对我不起作用。我遇到了异常。我可以通过编辑每台主机上的注册表并重新启动服务来解决此问题。

连接字符串存储在这里：HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AppFabric\V1.0\Configuration

该值被命名为“ConnectionString”

在用户配置单元下，有另一个连接字符串实例。我不知道你是否需要改变这个，但我做到了。 HKEY_CURRENT_USER\Software\Microsoft\AppFabric\V1.0\Temp

这对我有用。不要忘记您还需要在 C:\Program Files\AppFabric 1.1 for Windows Server 下编辑 DistributedCacheService.exe.config 中的 ClusterConfig ConnectionString

您需要调用Remove-CacheAdmin 然后Add-CacheAdmin 来更改每个管理主机上的缓存管理连接

This Microsoft Powershell script - （.EXE 下载，脚本转载如下） - 更改集群中所有主机上的连接字符串。

param ([string] $provider, [string] $newConnectionString)

function Main {

    if ( (! $provider) -or (! $newConnectionString))
    {
        Write-Host "Usage: ChangeConnString.ps1 <provider> <newConnectionString>"
        exit(1)
    }

    Import-Module "DistributedCacheAdministration"
    Import-Module "DistributedCacheConfiguration"

    Use-CacheCluster

    Write-Host "Stop the cache cluster if it is running"
    $clusterRunnig=$true
    &{
        Stop-CacheCluster -EA Stop
    }
    trap [DataCacheException] {  
        #'Error Category {0}, Error Type {1}, ID: {2}, Message: {3} {4}' -f  $_.CategoryInfo.Category, $_.Exception.GetType().FullName,  $_.FullyQualifiedErrorID, $_.Exception.Message, $_.Exception.ErrorCode;
        #12008: ErrorCode<ERRCAdmin008>:SubStatus<ES0001>:No hosts running in cluster
        if ($_.Exception.ErrorCode -eq 12008)
        {
            write-host "Cluster is not running"
            $clusterRunnig=$false
            continue
        }
    }

    [Reflection.Assembly]::LoadWithPartialName('Microsoft.ApplicationServer.Caching.Management') | Out-Null
    [Reflection.Assembly]::LoadWithPartialName('System.Management.Automation') | Out-Null
    [Reflection.Assembly]::LoadWithPartialName('System.Management.Automation.Runspaces') | Out-Null

    SetCacheConnectionString $provider $newConnectionString

    Write-Host "Connection string is altered on all the cache hosts. Now changing the connection string for cache admin"
    Remove-CacheAdmin
    Add-CacheAdmin -Provider $provider -ConnectionString $newConnectionString

    if ($clusterRunnig -eq $true)
    {
        Write-Host "Starting the cache cluster..." 
        Start-CacheCluster
    }
}

function SetCacheConnectionString {

    param ([string] $provider, [string] $newConnectionString)

    Write-Host "Parameters: " $provider " " $newConnectionString
    $powerShell = [System.Management.Automation.PowerShell]::Create()
    # Import the admin cmdlets module
    $powerShell.AddCommand("Import-Module", $true);
    $powerShell.AddParameter("Name", "DistributedCacheAdministration")

    # Call the Invoke method to run the commands
    $powerShell.Invoke();

    $powerShell.Commands.AddCommand("Use-CacheCluster")
    $powerShell.Commands.AddCommand("Get-CacheHost")
    $commandResults = $powerShell.Invoke()
    $powerShell.Dispose()

    Write-Host "Number of hosts in the cluster " $commandResults.Count
    foreach ($cacheHost in $commandResults)
    {
        Write-Host "Configuring the host " $cacheHost.HostName

        Invoke-Command -ComputerName $cacheHost.HostName -ScriptBlock {param ($provider, $newConnectionString) Import-Module DistributedCacheConfiguration;Remove-CacheHost;Add-CacheHost -Provider $provider -ConnectionString $newConnectionString -Account 'NT Authority\NETWORK SERVICE'} -ArgumentList $provider, $newConnectionString
    }
}
