Installation On Ionos (1und1) Webspace?
Totally new with This
Is it Possible to install the free version on Ionos web space?
Is there a step-by-step guide?
Hope for HELP
You can use one of the VPS tiers, I'd guess that the VSP S or VPS M tiers should work for NodeBB. Just install Ubuntu on one and follow the Ubuntu installation docs: https://docs.nodebb.org/installing/os/ubuntu/
Webserver in this case means
PHP / MYSQL / Apache 2
You would need node.js based Web-Environment
