READ CAREFULLY!

This process will make a ChainDB file on NKN node server and transfer it
to the web host server.

You need to provide a WEB HOST SERVER! Make another VPS server which you will
use to host the ChainDB file, so you can deploy your next NKN nodes faster!
Requirement: web host with 1 core, 512 MB RAM, 25+GB storage minimum.

STEP 1: I have no NKN nodes / servers:

YOU NEED TO DO THIS STEP ONLY ONCE!

Hosting the ChainDB archive yourself is essential to deploy your
future NKN nodes faster. You only need one ChainDB server.

Server requirements: 1+ CPU, 1+ GB RAM, 40+ GB of storage

Free credits for server providers: https://vpstrial.net/vps/

If THIS server already has enough storage space, continue by
selecting STEP 1. Otherwise exit this script and provision a new
VPS server.

STEP 2: Deploy new nodes:

RUN STEP 2 ONLY ON NEW SERVERS, not on the ChainDB server!!!
Make a new 1 core, 1GB RAM, minimum 25+ GB storage ubuntu 20.04+ server
and use the custom URL address provided to you in the first part of the
script to deploy new node servers.

If you give all three flags you can install the node directly without
messing with any menus. Any mistakes with the values will lead to a
broken node, which you'll have to reinstall. Enjoy :D

DO NOT REMOVE SINGLE QUOTES FROM FLAG VALUES!!

EXAMPLE:

wget -O nkndeploy.sh 'https://raw.githubusercontent.com/no112358/ALLinONE-nknnode/main/nkndeploy.sh'; bash nkndeploy.sh -p 'password' -b 'beneficiaryaddress' -w 'chaindbURL'

-p , --password       Set password
-b , --benaddress     Set beneficiary address where you get paid
-w , --websource      Set ChainDB URL address

-h , --help           Display help and exit
