Make and Unmake Sites, Automated; Single-Domain Version

This post is similar to Make and Unmake Sites, Automated with the difference that this is for a single-domain server created in Spinning up a single-domain web and email server.

Making a site in this version is a lot faster, as we already have the wildcard certificate for the domain we do not need to wait for CertBot to get a new one from Let’s Encrypt.

Let’s go over the sections of the script in detail first.

#!/bin/bash
RED='\033[0;31m'
GREEN='\033[0;32m'
CYAN='\033[0;36m'
NC='\033[0m' # No Color

#!/bin/bash

RED='\033[0;31m'

GREEN='\033[0;32m'

CYAN='\033[0;36m'

NC='\033[0m' # No Color

The above sets up our colors for the bash shell.

domain=`cat /root/domain`
echo -e "${CYAN}Enter the subdomain for the new site on $domain: ${NC}"
read subdomain
fqdn="$subdomain.$domain"
folder="/var/www/$fqdn"
echo -e "${CYAN}Creating root folder $folder{NC}"
mkdir "$folder"
echo -e "${GREEN}Done.${NC}"

domain=`cat /root/domain`

echo -e "${CYAN}Enter the subdomain for the new site on $domain: ${NC}"

read subdomain

fqdn="$subdomain.$domain"

folder="/var/www/$fqdn"

echo -e "${CYAN}Creating root folder $folder{NC}"

mkdir "$folder"

echo -e "${GREEN}Done.${NC}"

We ask the user for the subdomain, and append that to the domain.

Make the two config files for Apache. One for the http connection, and the other for https. The http forwards to the https, and we use HSTS.

Finally we reload Apache to bring the new subdomain online.

Removing the subdomain is super easy. We just delete the files and site root, after asking Apache to disable the subdomain.
