Steps I usually do to get a WordPress server up and running at Digital Ocean.
1 Create the droplet
They do have a WP server in the marketplace, but I tend to do it from scratch.
Usually go with Ubuntu 18.04 LTS.
I always provision with an ssh key set up from the get go, rather than getting sent a root password.
2 Security things
- enable http, https, and ssh
- disable remote password access (usually done already)
- but do set a root password and store in password manager, for those times you need to log in via the access console
3 WP related apps
- and a bunch of php extensions (php-xml, php-json, php-mysql, php-mbstring, php-zip, any others?)
