8-23-2015: Adding more laptops at home for 4 computer clusters (DONE)

I have 3 laptops at home. One was for my tv and one was an old crappy laptops. I don't want to use them for real work. So I got 2 more laptops and hooked them up to my monitor that has 2 hdmi ports. Now I have a cluster. Here is the steps I used to install.

• Install Linux
• Download the last Linux Mint and burn it.
• Put cdrom in external cdrm drive first. Bios might not detect this. 
• Reboot into bios and make the cdrom the first bootable device. 
• Remove secure boot in BIOS.
• Reboot 
•  When it comes to partitions:
• 100 megs for EDI parition
• 100 meg for swap, I know its an overkill. 
• 10000 megs for /BACKUP
• rest for /
• Post Install STEP 1
• In the control panel, for power management, set it to do nothing when the laptop is closed and turn off any power management after a time.
• Run  the script I have below. 
• In screensaver, make bsod the default and no locking when screensaver is activated. Who cares. This is for testing. 
• Post Install Step 2 . 
• Add the two systems to DNS 
• Install DNS on the two systems
• Exchange SSH keys. 
• Install SALT on those two systems. 
• Then for the future, I have a cluster of 3 servers for mono, vertica, voltdb, MySQL and Galera, and maybe MaxScale.
