Power Users

cloud-init

If you know if your server provider has cloud init, you're a power user. A few hosts that have cloud-init include OVH, Hetzner, Digital Ocean, Vultr and many many more. Here's our custom cloud-init that will prep any VPS for Harmony! Thanks for the security hardening tips from here (opens in a new tab).

To use the code below simply replace the ssh-rsa key with your id_rsa.pub key and set the username you would like to use on the server (Change serviceharmony or serviceuser in the examples below).

Security Notes:

• You can customize any of this!
• We included a config that sets up UFW for you if you use it! Cloud providers may have their own firewall, your choice!
• Inject your - ssh-rsa ...Your Key Here... into the cloud-init users section below as 1 line with the full key.

Note: The cloud-init does take a few minutes to run after your server comes online. Wait a few minutes for this to complete or verifiy it finishes up by watching the logs with sudo tail -f /var/log/syslog to see it complete.

Harmony
