Powershell脚本启动服务如果它已停止并等待一分钟并发送电子邮件通知

Question

我是Powershell的新手,在学习阶段,我尝试创建一个脚本来执行自动化任务.此脚本无法正常工作.你能否回顾一下,给我一些帮助.

我的任务是,

我试图找出处于停止状态并尝试启动它的SQL服务(多个服务器中的多个SQL服务),等待一分钟完成服务启动并再次验证服务状态.如果它仍然停止状态我正在尝试发送电子邮件以设置人员进行操作.

你能否检查下面的代码并纠正错误,我试图找到它但无法做到

#Define servers & Services Variables
$Servers = GC "E:\Bhanu\SQLServer.txt"
$Services = GC "E:\Bhanu\SQLService.txt"

#Function Call
Function ServiceStatus ($Servers, $Services)
{
    foreach ($Server in $Servers)
    {
        foreach ($Service in $Services)
        {
            $Servicestatus = get-service -ComputerName $Server -Name $Service
            if ($Servicestatus.Status -eq "Stopped")
            {
                Start-service $Service          
                Start-Sleep -Seconds 60            
                $ServiceStatus1 = Get-Service -ComputerName $Server -Name $Service
                if ($Servicestatus1.Status -eq "Stopped")
                {            
                FuncMail -To “abc@gmail.com” -From “abc@gmail.com” -Subject $Server + $Service "fails to Start, Take immediate Action to avoid Impact” -Body $ServiceName "Service fails to Start, Take immediate Action to avoid Impact” -smtpServer “servername”
                }
            }
        }
    }
}


function FuncMail 
{
    #param($strTo, $strFrom, $strSubject, $strBody, $smtpServer)
    param($To, $From, $Subject, $Body, $smtpServer)
    $msg = new-object Net.Mail.MailMessage
    $smtp = new-object Net.Mail.SmtpClient($smtpServer)
    $msg.From = $From
    $msg.To.Add($To)
    $msg.Subject = $Subject
    $msg.IsBodyHtml = 1
    $msg.Body = $Body
    $smtp.Send($msg)
}

servicestatus $ Servers $ Services

如果您需要我的任何内容,请告诉我

嗨，这不是最好的方法，我正在以快速的方式做到这一点。注意 %=foreach-object; ?=Where-对象。

如果您的 smtp 服务器需要身份验证，则必须将密码保存在一个文件中，否则请勿使用read-host -assecurestring | convertfrom-securestring | out-file "C:\Secure\Password.txt"

我还假设您将服务器保存在一个文件中。
我的解决方案是启动所有 sql server 服务，如果您想启动特定的服务，只需将服务名称保存在一个文件的单独一行上。

要执行的代码如下。

#Loading Server and service details
$Services=Get-content C:\PS\Service.txt
$servidores=get-content C:\PS\Servers\Servers.txt

#Loading Mail credential
$Mailpasswordpath="C:\PS\Securestring.txt"
$Mailusername="DOmain\User"
$password=cat $Mailpasswordpath |ConvertTo-Securestring
$Cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $Mailusername,$password


$servidores|Foreach-Object{Get-Service -ComputerName $_ -Name $Services }|  #Get the services running on all servers
Where-Object{$_.Status -eq "Stopped"}| #Which status is equal stopped
Foreach-Object{
     $_.Start(); #try to start
     Start-Sleep -Seconds 60;  #wait one minute
     $_.Refresh();  #refresh then service to update status

     #validate is status still stopped
     if($_.Status -eq "Stopped") 
     {
         #LOADING Mail details
         $To="user@domain.com"
         $subject="$($_.MachineName) $($_.Name)  fails to Start, Take immediate Action to avoid Impact"
         $From="ServiceStatus@domain.com"
         $smtp="Server.domain.com"
         $body="$($_.Name) Service fails to Start, Take immediate Action to avoid Impact"

         #Sending email to notify
         Send-MailMessage -To $To -Subject $subject  -From $From  -SmtpServer $smtp  -Body $body  -Credential $Cred
     }
}

PS：这不是最好的方法，我只是决定解决这个问题。如果您愿意，我们可以稍后一起创建一个函数，只需先测试它即可。
