Apache2 vhost on web server

This script makes the creation of virtual hosts on Apache2 web server quicker and easier. The script is meant to be used for production web sites so it expects that all of the traffic will use HTTPs. If you need similar script to use on local machine for test purposes please use https://samiwell.eu/linux/create-apache-2-vhost

#!/bin/bash
# The scipt automates the proccess of creation of virtual hosts on Apache 2 web server
# NOTE:
# 1. The script requires root previleges
# 2. The script allowes .htaccess override by default
# 3. The v-host directory will be dedecated to user and group www-data
# 4. The .htaccess file will redirect to https
