Why this repository?

To help others (beginners like me) to build secure digitalocean droplets effectively.

Useful Notes

1. I prefer Ubuntu OS for droplets so you'll find shell commands accordingly.
2. I've mentioned several references available on internet which are/were useful to me.
3. I've mostly specified -y option on installation commands which don't prompt me to confirm
4. If you are unsure about any command how to use it, then always execute it with --help or -h. e.g. certbot --help
5. Installed services can be found under /etc/init.d directory and service can be restarted using /etc/init.d/sendmail restart
