When installing the Azure Stack MySQL resource provider, this needs to be done from a computer where Azure Stack and Azure PowerShell have been installed. If you have installed any versions of the AzureRM or Azure Stack PowerShell modules other than 1.2.9 or 1.2.10, you will need to remove them. This includes versions 1.3 or higher.
Now we need to download the resource provider. Download the location for the MySQL resource provider at https://aka.ms/azurestackmysqlrp.
After you have downloaded the file, you will need to log on as AzureStackAdmin account and extracted it on the deployment VM.
