In this episode of Community Casts, we'll create a new Ubuntu 18.04 server and follow DigitalOcean's Initial Server Setup Guide to:

  • Create a new system user and grant them sudo privileges.
  • Set up SSH access for the new user.
  • Enable a firewall.

This video is also available on Youtube.


DigitalOcean is the cloud of choice for developers around the world to create modern applications.


Editor guide

Is there a tutorial on hardening server?


Hi! We don't have a specific procedural guide on that (thanks for the idea by the way) but we have a more conceptual article that could be of help: 7 Security Measures to Protect your Servers.


thanks, this is solid, looking forward to step by step config.


They KIND of do, depending on what server OS you want to use.

I was focusing on CentOS servers since it's the downstream of RHEL. They had great guides for getting a server stood up and usable, and then a follow up guide on how to start locking it down.




thanks, bookmarked the second link

Just know that the link you bookmarked is for CentOS and the article we're commenting on is Ubuntu.


Seriously, for a long while, I was just Googling "thing I need to figure out DigitalOcean docs".


Everyone new-ish to being a sys-admin should be paying way more attention to @DigitalOcean's screencasts and documentation.

They're insanely well prepared and I used them more than I'd like to admin in my last role with the US Courts and even in creating an eLearning course teaching people how to set up and run their own web servers.


thank you! :)


Wouldn't have the DevOps career I have now without your documentation over the last few years. Full stop. :)


Link is broken it appears.


Thanks for spotting that! It is fixed now :)
