Lab preparation process

Ideally, the lab preparation process can be divided into two main categories, one is hardware setup and the other is software setup.

2.1 Hardware setup

In the hardware setup, the process starts with power plugs and LAN ports availability, tests for their functioning status, then all the computers will be set up with preplanned arrangement as per space layout, power and LAN ports availability. Afterwards, the switch/wifi router will be connected and all the client machines and server machines will be connected together via LAN cable or wifi. The server machines should have UPS backups as those will be carrying the resources and student’s data, artifacts, and will be of utmost importance

2.2 Software setup: Once the hardware setup is done, the next major preparation is the software setup which includes following steps:

OS (Ubuntu 18.04) Installation Guide
Preparation for Installation:

Bootable USB drive/DVD with Ubuntu 18.04 ISO image loaded into it (installation media)
Most reliable UPS or follback power source (available in school lab) along with main power source connected to clix server machine.
Make sure that you have taken backup of existing data in the internal hard disk of the machine if there is any existing data.
Do not connect internet to machine on which installation needs to be done (machine should be offline, detach LAN cable from machine)

Note: Before proceeding, for CLIx server machine setup, the following steps should be followed:

Note down existing IP address of the CLIx server machine: (to list IP address use $ `ifconfig | less`)
If the system already has CLIx Platform installed, Backup existing data from clix server machine.Please refer to “Steps to Download Complete Platform Data” section
Format/Clean existing internal HDD of the server machine (following command assumes that internal HDD is detected at /dev/sda).
Command: “sudo dd if=/dev/zero of=/dev/sda bs=512MB count=2”
Shutdown the machine properly, if the machine remains in prompt display mode, hard shutdown the machine using power button on CPU, by long pressing it till machine gets shut down.
