how to start Tomcat process and postgre SQL process with runbook powershell workflow in Linux of azure VM

Question

Hello

Someone knows how to start Tomcat process and postgre SQL process with azure automation runbook（powershell flow）in the system of Linux of VM.

I am making a powershell work flow runbook to start postgre DB process and Tomcat process in Linux system of VM of azure.

There are some templates just start VMs.
Could someone give me a template or tell me how to run Linux commands like「service Tomcat start」in runbooks

Need API or else ？

Best Regard

Hi @Rory_Feng ,

To remotely run linux command like "service tomcat start" in VM via Azure Automation runbook, you may follow one of the below 2 approaches.

1. Create an Azure storage account, container and upload a blob i.e., script (say tomcat_service_start.sh file with the content "service tomcat start") and then have below code in Azure Automation PowerShell runbook.

$connectionName = "AzureRunAsConnection"
$servicePrincipalConnection = Get-AutomationConnection -Name $connectionName
$ConnectToAzAccount = Add-AzAccount -ServicePrincipal -TenantId $servicePrincipalConnection.TenantId -ApplicationId $servicePrincipalConnection.ApplicationId -CertificateThumbprint $servicePrincipalConnection.CertificateThumbprint

$StorageAccountName = "xxxxxxxxxxxxx"
$StorageAccountKey = "xxxxxxxxxxxxxx=="
$ContainerName = "xxxxxxxxxxxxxxx"
$BlobName_Linux = "tomcat_service_start.sh"
$RG_VM = "xxxxxxxxxxxxxxxxxx"
$VM_Name_Linux = "xxxxxxxxx"
$InvokeCmd_Id_Linux = "RunShellScript"

$AzStorage = New-AzStorageContext -StorageAccountName $StorageAccountName -StorageAccountKey $StorageAccountKey
$AzStorageContext = $AzStorage.Context

$GetBlobContent_Linux = Get-AzStorageBlobContent -Container $ContainerName -Blob $BlobName_Linux -Destination ($Env:temp+"/tomcat_service_start.sh") -Context $AzStorageContext -Force
$InvokeRunCmdOutput_Linux = Invoke-AzVMRunCommand -ResourceGroupName $RG_VM -VMName $VM_Name_Linux -CommandId $InvokeCmd_Id_Linux -ScriptPath ($Env:temp+"/tomcat_service_start.sh")
$TomcatServiceStart_Output_Linux = $InvokeRunCmdOutput_Linux.Value[0].Message
Write-Output $TomcatServiceStart_Output_Linux

2. Save a script (say \home\xxxx\tomcat_service_start.sh) in your VM and have the linux command "service tomcat start" as content in that file and then have below code in Azure Automation PowerShell runbook.

$ServicePrincipalConnection = Get-AutomationConnection -Name 'AzureRunAsConnection'
Add-AzAccount -ServicePrincipal -TenantId $ServicePrincipalConnection.TenantId -ApplicationId $ServicePrincipalConnection.ApplicationId -CertificateThumbprint $ServicePrincipalConnection.CertificateThumbprint
$rgname ="rrrrrrrrrrrrrr"
$vmname ="vvvvvvvvvvvvvv"
$ScriptToRun = "\home\xxxx\tomcat_service_start.sh"
Out-File -InputObject $ScriptToRun -FilePath ScriptToRun.sh
Invoke-AzVMRunCommand -ResourceGroupName $rgname -Name $vmname -CommandId 'RunShellScript' -ScriptPath ScriptToRun.sh
Remove-Item -Path ScriptToRun.sh

Note:

• Before trying any of the above approaches, make sure you import required cmdlets modules in your Azure Automation Account.
• Above approaches are with PowerShell runbook so you may have to tweak them to re-use in PowerShell workflow runbook.
