How to install Ubuntu with LUKS Encryption on LVM

My work requires us to have full-disk encryption, so these are the steps I use.

The basic idea is to create a LUKS-encrypted partition which is used as an LVM Physical Volume.

The GRUB boot partition isn't encrypted, but everything else is.

These steps tested and working on 22.04 (jammy) and 20.04 (focal).

Zabbix REST/JSON web service check script

	For REST/JSON web service that returns :
	{
	"DatabaseConnections": [
	{
	"DatabaseName": "database1",
	"DatabaseStatus": "Open",
	},
	{
	"DatabaseName": "database2",
	"DatabaseStatus": "Open",

Procedurally generated man pages; each man page gets its own color scheme.

	#Author: Malsententia <Malsententia@gmail.com>
	#Purpose: Colorized man pages, with random themes seeded by
	# the command and/or section. That is, every man page
	# has its own consistent color scheme. For example
	# man tar is always yellow, green, and blue, man less
	# is always pink, blue, and yellow, etc.(on zsh, anyway)
	#Note: Colorization will differ between bash and zsh, since their
	# RNGs are different
	#Requires: bash or zsh(may support others), and perl
	#Setup: Name it .mancolor.sh, source it in your bashrc/zshrc,

Parallel rsync script for copying failed GlusterFS bricks (self-heal daemon is too slow!)

	#!/bin/env bash
	# borrowed / adapted from: https://wiki.ncsa.illinois.edu/display/~wglick/Parallel+Rsync

	# RSYNC SETUP
	RSYNC_PROG=/usr/bin/rsync
	# note the important use of --relative to use relative paths so we don't have to specify the exact path on dest
	RSYNC_OPTS="-aAXv --numeric-ids --progress --human-readable --delete --exclude=.glusterfs --relative"
	export RSYNC_RSH="ssh -T -c arcfour -o Compression=no -x"

	# ENV SETUP

Sub-CA example

	# Assumptions: easyrsa3 available in current dir, and functional openssl.
	# This basic example puts the "offline" and "sub" PKI dirs on the same system.
	# A real-world setup would use different systems and transport the public components.

	# Build root CA:
	EASYRSA_PKI=offline ./easyrsa init-pki
	EASYRSA_PKI=offline ./easyrsa build-ca nopass

	# Build sub-CA request:
	EASYRSA_PKI=sub ./easyrsa init-pki
