Powershell 使用DSC设置服务启动

我是新手。MOF文件生成失败

PSDesiredStateConfiguration\Node:参数为null或空。 请提供一个不为null或空的参数，然后重试 再次指挥。第13行字符：5+节点本地主机+~~~+ CategoryInfo:MetadataError:：[PSDesiredStateConfiguration\node]， ParentContainesErrorRecordException+FullyQualifiedErrorId: ArgumentIsNull，PSDesiredStateConfiguration\node编译错误 处理配置“SQLConfig”时发生

请查看错误流中报告的错误，并修改您的 适当的配置代码。在 C:\windows\system32\WindowsPowerShell\v1.0\Modules\PSDesiredStateConfiguration\PSDesiredStateConfiguration.psm1:3917 char:5+抛出$ErrorRecord+~~~~~~~~~~~~~~~~~~~~~~~~~+类别信息： InvalidOperation:SQLConfig:String[]，InvalidOperationException+ FullyQualifiedErrorId:FailToProcessConfiguration

几个小问题

首先，您正在配置服务，而不是服务集，因此底部foreach循环中的资源名称不正确

其次，您已配置的资源的名称ServiceSet$service需要是一个字符串，更像service$service.ServiceName

第三，您已经指定$ServiceConfig参数是一个字符串数组，但您提供的是一个hashtables数组HashTable[]。您需要更新配置参数类型

第四，忽略的状态值无效。它应该正在运行或停止

顺便说一句，在最后的SQLConfig调用中添加-Debug可以让您逐步完成许多配置，以查看它的运行位置。不是银弹，但会有帮助。

    Configuration SQLConfig {
        param(
            # Parameter help description

            [Parameter(Mandatory =$true)][string]$DataDrive,
            [Parameter(Mandatory =$true)][string]$LogDrive
