Question

PS脚本场景

1-> Check if service exists
     -> if doesn't exists
        -> copy item and install windows service and start.
     -> If exists
        -> Stop Windows service & delete it and copy item from folder and Install & start the service.

以下是我的剧本

$service = Get-Service -Name XXX -Computername YYY
if($service.Status -eq $NULL)
{
    Copy-Item "C:\location\*" "\\yyy\d$\Location" -Force -Recurse
    sc.exe \\yyy create xxx start=auto DisplayName="value"  binPath= D:\Build\test.exe
    sc.exe \\yyy description xxx "value"
    sc.exe \\yyy start xxx
    Write-Host "xxx STARTED"
}
else
{
    sc.exe \\yyy stop xxx
    Write-Host "xxx STOPPED"
    sc.exe \\yyy delete xxx 
    Write-Host "xxx DELETED"
    Copy-Item "C:\Location\*" "\\yyy\d$\Location" -Force -Recurse
    sc.exe \\yyy create xxx start=auto DisplayName="value"  binPath= D:\Build\test.exe
    sc.exe \\yyy description xxx "value"
    sc.exe \\yyy start xxx
    Write-Host "xxx STARTED"
}

我的方法是否正确，如果没有服务名称XXX，我会看到错误。如何覆盖此错误并继续使用If条件语句。

错误 -

Get-Service : Cannot find any service with service name 'Spoole'.
At line:1 char:12
+ $service = Get-Service -Name Spoole
+            ~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Spoole:String) [Get-Service], ServiceCommandException
    + FullyQualifiedErrorId : NoServiceFoundForGivenName,Microsoft.PowerShell.Commands.GetServiceCommand

Answer 1

您可以使用

$service = Get-Service -Name XXX -Computername YYY -ErrorAction SilentlyContinue

压制错误。

用于检查服务状态和安装新Windows服务的PS脚本
