Installation on Azure cloud

ProSBC Azure Image

A virtual machine image is a single file that contains a virtual disk that has a bootable operating system installed on it. Images are used to create virtual machine instances in the cloud.

The following sections describe how to upload the latest ProSBC image to your Microsoft Azure account and launch a virtual machine instance running the ProSBC software.

Get a Storage Account

You will need a blob container in your Azure storage account. This blob container is required to upload and store a ProSBC VM image. You can either use an existing storage account or create a new one, but make sure that the storage account location matches the location where you plan to create and run your VM.

Create Resource Group

If you need to create a storage account to upload the VM image, then you will need a resource group that matches the location where you plan to create and run your VM. If required, create a resource group as follows:

• Log in to the dashboard.
• Select 'Resource groups'.
• From 'Resource groups', click 'Add' item.
• The 'Create a resource group' dialog box appears.
• Provide a name for the resource group.
• Select the appropriate resource group location. This is where you will be creating the VM.
• Click 'Review + Create'.

• Wait for completion of the resource group creation before proceeding with the next steps.

Create Storage Account

If you require a storage account, do the following:

• Log in to the dashboard.
• Select 'Storage accounts'.
• From 'Storage accounts', click 'Add' item.
• The 'Create a storage account' dialog box appears.
• Select the appropriate resource group.
• Provide a name for the storage account.
• Select the appropriate storage account location. This is where you will be creating the VM.
• For the other parameters, consult https://docs.microsoft.com/en-us/azure for more details.
• Click 'Review + Create'.

• Wait for completion of storage account creation before proceeding with the next steps.

Create Storage Blob Container

If you require a blob container, do the following:

• Log in to the dashboard.
• Click 'Storage accounts'.
• Select a storage account item to add the blob container.
• Click Blob Services button.

• For the other parameters, consult https://docs.microsoft.com/en-us/azure for more details.
• Click 'Ok'.

• Wait for completion of storage blob container before proceeding with the next steps.

Upload a Virtual Hard Disk (VHD) Image

Follow this procedure to upload the ProSBC image to a storage blob container:

• Before being able to upload the ProSbc image to the storage blob container, you must uncompress (tag.gz) the ProSBC image locally on your PC. You will require at least 40 GB of free space to uncompress the image.
• Log in to the dashboard.
• Click'Storage accounts'.
• Select the appropriate 'storage account' then 'Blobs' container.

• From the 'Blobs' container top menu, Click 'Upload' menu item.
• The 'Upload blob' dialog box appears.
• Select the Virtual Hard Disk image (freesbc_azure.vhd) to upload from your local disk image location.
• Click 'Upload' button.

• Wait until upload completion before proceeding with the next steps. This operation will take a long period of time (40GB to upload).

Create a VM Image from the ProSBC storage blob

Follow this procedure to create a VM image from a storage blob:

• Log in to the dashboard.
• Select 'Create a resource'.
• The 'Create resource' dialog box appears.

• Click 'Create'.

• Provide an image name.
• Select the appropriate resource group.
• Select the appropriate location.
• Click on 'Linux' button for the OS type.
• Browse through storage accounts to select the ProSBC blob.
• Click 'Select' button to complete ProSBC blob selection.
• For the other parameters, consult https://docs.microsoft.com/en-us/azure for more details.
• Click 'Create' button.

• Wait until create completion before proceeding with following steps.

Create a Virtual Network

• Log in to the dashboard.
• Select 'Virtual networks'.
• The 'Virtual networks' dialog box appears.
• From 'Virtual networks' top menu, click 'Add' item.
• The 'Create a virtual network' dialog box appears.
• Provide a virtual network name.
• Provide the virtual network's address range in CIDR notation.
• Select appropriate resource group.
• Select appropriate location.
• Provide subnet name and address range.
• For the other parameters, consult https://docs.microsoft.com/en-us/azure for more details.

Add Inbound Security Rules

Follow this procedure to add inbound security rules:

• Log in to the dashboard.
• Select 'Virtual machines'.
• The 'Virtual machines' list dialog box appears.
• Select the appropriate virtual machine to add inbound security rules.
• The virtual machine overview dialog box appears.
• Select 'Networking' item from the virtual machine 'Settings' section.
• Click the 'Add inbound port rule' button.

• The 'Add inbound security rule' dialog box appears.
• Fill the different fields in accordance with the expected VM accessibility from public network.

• Open a shell command prompt, which is Azure CLI capable (consult https://docs.microsoft.com/en-us/azure to install the Azure CLI).
• Enter the following command, using the correct network interface name and resource group, and press enter:

 az network nic update --name azure-1if-2801 --resource-group sw_group --accelerated-networking true

• The Azure CLI command output will look like the following:

• Rebooting will NOT activate the 'Accelarated Networking' on the VM network interface. It is required to do the following operations to complete 'Accelarated Networking' activation:
  • First, 'Stop' the virtual machine (This will take some time to stop the virtual machine).
  • Then, 'Start' the virtual machine.

Accessing the ProSBC

ProSBC SSH Access

By default, there is no root password. You will need to SSH on to the ProSBC using an SSH private key matching the public provided in the SSH public key when #Instantiate a FreeSBC instance. Log in using centos as username.

For example, if your ProSBC management IP is 192.168.178.30:

 > ssh centos@192.168.178.30
   ECDSA key fingerprint is 5d:94:a1:93:0f:a4:7a:5d:41:cc:29:49:79:5a:58:f3.
   Are you sure you want to continue connecting (yes/no)? yes
   Warning: Permanently added '192.168.178.30' (ECDSA) to the list of known hosts.
   
   CentOS-7-x86_64-Minimal-1511/112/190195:197392, Fri  7 Apr 17:41:46 EDT 2017
   [centos@freesbc ~]$

Accessing the ProSBC web portal

• Open a web browser to the management IP of the ProSBC, on port 12358. For example, if your server address is 192.168.178.30, the URL would be:
  http://192.168.178.30:12358
• You should get to the ProSBC Configuration Wizard
  

From this point, go to Web Portal Initial Configuration Guide to continue the installation.
