12. Complete details for your front page (name of your Moodle, etc)

TOPIC03/05

Installing Moodle


Capture a Linux Virtual Machine to Use as a Template for auto scale Moodle

Connect to the virtual machine using an SSH client of your choice

In the SSH window, type the following command.

sudo waagent -deprovision

This command will attempt to clean the system and make it suitable for re-provisioning. This operation performs the following tasks:

Removes SSH host keys (if Provisioning.RegenerateSshHostKeyPair is 'y' in the configuration file)

Clears nameserver configuration in /etc/resolv.conf

Removes the root user's password from /etc/shadow (if Provisioning.DeleteRootPassword is 'y' in the configuration file)

Removes cached DHCP client leases

Resets host name to localhost.localdomain

Deletes the last provisioned user account (obtained from /var/lib/waagent) and associated data.

TOPIC04/05


1. Type y to continue. You can add the -force parameter to avoid this confirmation step.

2. Type Exit to close the SSH client.

3. Open Azure Management Portal to your azure Subscription

4. Shut down the virtual machine which is already deprovisioned in the steps above with

5. When the virtual machine is stopped, capture the image with

6. The new image is now available in the list of images that can be used to configure any new virtual machines, for autoscalling

7. Click on the cloud Service on the Azure Portal
