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

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.
