mk-subdomain

A small bash file for quickly creating new subdomains on the standard DigitalOcean 'LAMP on Ubuntu' server image.

I'm presuming:

  1. you have a server set up on DigitalOcean
  2. you have already configured your domain name for this server

How to use

###1 - prepare your DNS

Make sure you have a wildcard ( * asterix ) CNAME entry in your DNS settings (in DigitalOcean). this will make sure all subdomains are correctly routed to your server.

alt tag

You'll have to wait a while for the DNS update to propagate.

You'll know this is working when yourdomain.com, www.yourdomain.com, foo.yourdomain.com all show the same page.

###2 - download the script

ssh into your server and from the home directory download the script:

wget https://raw.githubusercontent.com/RShergold/mk-subdomain/master/mk-subdomain

then make it executable:

chmod +x mk-subdomain

###3 - tell the script what your domain name is

The script needs to know your domain name. replace your_domain_here with your actual domain below

sed -i "s|example.com|your_domain_here|g" mk-subdomain

###4 - move the defult documents directory (optional)

./mk-subdomain init

This moves the standard directory for yourdomain.com from /var/www/html to /var/www/default/html

###5 - make a new subdomain

now whenever you wish to create a new subdomain just do

./mk-subdomain subdomainname

this creates subdomainname.yourdomain.com and a documents directory at /var/www/subdomainname/html
