![Powershell v2 脚本需要一些帮助](https://linux22.com/image/522644/Powershell%20v2%20%E8%84%9A%E6%9C%AC%E9%9C%80%E8%A6%81%E4%B8%80%E4%BA%9B%E5%B8%AE%E5%8A%A9.png)
我有一个用于启动服务的 powershellv2 脚本,但我无法让它正常工作,我知道 start-service 命令只能在本地工作,但我似乎无法让 (gwmi win32_service -computer $comp -Filter "name='$serviceName'").StartService() 命令工作,我收到以下错误
您无法对空值表达式调用方法。第 1 行,字符:146 + (Get-WmiObject win32_service -computer cap-test4-biz1 -Credential captest\jola_adm -filter "Name='BTSSvc$BizTalkServerApplication'").invokemethod <<<< ("StartService",$null) + CategoryInfo : InvalidOperation: (invokemethod:String) [], RuntimeException + FullyQualifiedErrorId : InvokeMethodOnNull
我已经粘贴了下面的脚本,希望有人能帮忙
$computername = "remoteserver"
$password = type H:\Powershell\MyPassword.txt | ConvertTo-SecureString
$cred = New-Object -TypeName System.Management.Automation.PSCredential -argumentlist “domain\user”,$password
function StartIfStopped([string]$ServiceName) {
$Service = Get-WmiObject Win32_Service -computername $computername -cred $cred -Filter "name='$ServiceName'"
if (!$Service) {
# Service is not installed
Write-Host "$ServiceName is not installed on this machine."
} else {
# Service is installed
if ($Service.State -eq "Stopped") {
if ($Service.StartMode -eq "Disabled") {
Write-Host "Cannot start service $ServiceName as it is disabled."
} else {
Write-Host "Starting service $ServiceName ..."
Start-Service $ServiceName
}
} else {
Write-Host "$ServiceName is already running."
}
}
}
StartIfStopped 'BTSSvc$BizTalkServerApplication'
StartIfStopped 'BTSSvc$TASMSMQHost'
StartIfStopped 'BTSSvc$TASProcessingHost'
StartIfStopped 'BTSSvc$TASSendHost'
StartIfStopped 'BTSSvc$TASTrackingHost'
答案1
我认为这是将密码转换为 SecureString 造成的。我通过将第 2 行更改为以下内容,使您的脚本正常工作:
$password = type H:\Powershell\MyPassword.txt | ConvertTo-SecureString -AsPlainText -Force
默认情况下,ConvertTo-SecureString
以加密字符串作为输入。 -AsPlainText
告诉它使用纯文本字符串。
然后你就可以将密码存储在文本文件中......

$computername = Get-Content H:\computers\Computers.txt;
$password = type H:\Powershell\MyPassword.txt | ConvertTo-SecureString
$cred = New-Object -TypeName System.Management.Automation.PSCredential -argumentlist “domain\user”,$password
$filename = "{0:yyyy-MM-dd} start" -f (Get-Date)
$tid = Get-Date -f HH:mm:ss
function StartIfStopped([string]$ServiceName) {
$Service = Get-WmiObject Win32_Service -computername $computername -cred $cred -Filter "name='$ServiceName'"
if (!$Service) {
# Service is not installed
Write-Host "$ServiceName is not installed on $computername."
} else {
# Service is installed
if ($Service.State -eq "Stopped") {
if ($Service.StartMode -eq "Disabled") {
Write-Host "Cannot start service $ServiceName as it is disabled."
} else {
#Write-Host "Starting service $ServiceName ..."
Write-Output "$tid Starting $ServiceName ." >> H:\logfiler\$filename.txt
#virker kun lokalt på servere
#Start-Service $ServiceName
#virker på remote servere også i andre domainer
(Get-WmiObject Win32_Service -filter "name='$ServiceName'" -computername $computername -cred $cred ).StartService()
}
} else {
#Write-Host "$ServiceName is already running."
Write-Output "$tid already running $ServiceName." >> H:\logfiler\$filename.txt
}
}
}
StartIfStopped 'BTSSvc$BizTalkServerApplication'
StartIfStopped 'BTSSvc$TASMSMQHost'
StartIfStopped 'BTSSvc$TASProcessingHost'
StartIfStopped 'BTSSvc$TASSendHost'
StartIfStopped 'BTSSvc$TASTrackingHost'
StartIfStopped 'BRNTService'
StartIfStopped 'TimerService'
StartIfStopped 'BouncedMailTracker'
StartIfStopped 'CMToolService'
StartIfStopped 'CalculationExcelService'
StartIfStopped 'ControlNTService'
StartIfStopped 'EnvelopeService'
StartIfStopped 'PrinterService'
更新脚本,我让它运行了,但现在我需要它登录多个服务器并启动服务。

我知道这个问题已经是6年前的问题了,但无论如何。
查看错误消息。问题在于 BTSSvc$BizTalkServerApplication 中的 $ 以及所有其他带有 $ 的服务名称。必须像这样进行转义:
Get-WmiObject -ClassName Win32_Service -Filter "Name='BTSSvc`$BizTalkServerApplication'"
