Worth looking at more detailed notes on my firewall configuration.
The firewall is already configured by DigitalOcean in my choice of droplet (Ubuntu 20.04 with WordPress). However if other services are to be added (in my case yes) the Ubuntu firewall needs to be configured. See below for some extra documentation links I referred to:
- HowTo Geek: How to Configure Ubuntu’s Built-In Firewall
- Ubuntu Documentation: Ubuntu firewall
Configure Apache & WorPress
In general, follow scripts/prompts when first SSH into droplet.
See apache for all details. By default for one WordPress instance, with no other sites or clever stuff, no other changes need to be made.
