How to install ERPN (MariaDB ready, Redis ready)

I already have a cloud server, installed with MariaDB and Redis. How can i install ERPN in this server? The guide only assume to get started using the disk image containing everything.

installation is pretty straighforward
you can start from here

I just don’t understand the part where it says:
Install bench as a non root user

As non root, does it means any username with root privilege or the root username? My VPS has disabled root access.

other user except root
you might have to use sudo command in order to start/restart service after
installation

recommendation is using full priviledges virtual machine / vps like
DigitalOcean or Dediserve

Yes i am using DigitalOcean. I follow the manual. At this step

bench get-app erpnext https://github.com/frappe/erpnext

I got error:

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-wqaDfb/frappe
