云服务程序在启动的时候执行Powershell脚本

如果在云服务程序启动时候，需要执行Powershell脚本，我们需要将脚本嵌入到程序中，并且编写一个cmd来执行这个脚本，具体如下：

1.编写测试的Powershell脚本：每隔10分钟 检测dns

$TimeStart = Get-Date
$TimeEnd = $timeStart.addminutes(1440)
$name = "cnppmedia.blob.core.chinacloudapi.cn."
$result = "d:\nslookuplog.txt"
Write-Host "Start Time: $TimeStart"
write-host "End Time: $TimeEnd"

Do {
 $TimeNow = Get-Date
  if ($TimeNow -ge $TimeEnd)
  {  Write-host "It‘s time to finish." }
  else
  {
    try
    {
        Write-host "===========NslookUp====Current Time : $(Get-Date)=============="
     invoke-command -scriptblock{ Write-Output "===========Test At Azure ====Current Time : $(Get-Date)=============="  | out-file -FilePath $result -Append -Force  }
     invoke-command -scriptblock{ nslookup $name | out-file -FilePath $result -Append -Force }
    }
    Catch
    {
    }

  } 

  Start-Sleep -Seconds 600
  }
  Until ($TimeNow -ge $TimeEnd) 

2.编写一个cmd文件来执行这个脚本：

echo Configuring powershell permissions
powershell -c "set-executionpolicy unrestricted"

echo start test dns
PowerShell .\testdns.ps1

if %ERRORLEVEL% neq 0 goto error

echo SUCCESS
exit /b 0

3.将这2个文件嵌入到程序中，并且都设置"Copy always"属性：

4.修改csdef文件，添加启动任务Startup

<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="testdnswithsdk26" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition" schemaVersion="2015-04.2.6">
  <WebRole name="WebRole1" vmsize="Small">
    <Startup>
      <Task commandLine="testdns.cmd" executionContext="elevated" taskType="background"/>
    </Startup>
    <Sites>
      <Site name="Web">
        <Bindings>
          <Binding name="Endpoint1" endpointName="Endpoint1" />
        </Bindings>
      </Site>
    </Sites>
    <ConfigurationSettings>
      <Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" />
    </ConfigurationSettings>
    <Endpoints>
      <InputEndpoint name="Endpoint1" protocol="http" port="80" />
    </Endpoints>
  </WebRole>
</ServiceDefinition>

因为测试的powershell脚本要连续执行一段时间，所以需要将任务类型设置为background，否则无法完成部署
