Arionum Masternode setup guide [CentOS 7]

[AroDev]

This guide aims to provide a quick way to create your own Arionum masternode.

It's meant for non-technical people and it's mostly plug and play.

The only thing you should figure out on your own is how to use putty to access your VPS over ssh.

Start by buying a VPS with 2 cores, 4GB RAM, 50GB Disk space.

We recommend the following VPS providers:
https://www.vultr.com
https://www.digitalocean.com
https://www.vps.ag
https://www.contabo.com
https://www.mvps.net

Once you have your VPS, ssh to it using putty, login and copy and paste (right click on putty window) the following commands:

Access your node in the browser using it's public IP.

Afterwards, we setup the CLI wallet on a secure server.

Code: Select all

cd /root
git clone https://github.com/arionum/lightWalletCLI
cd lightWalletCLI
chmod +x light-arionum-cli
./light-arionum-cli balance

This will create a new wallet and print your address, private key and public key. Save them.

On the node VPS, run:

Code: Select all

nano /var/www/html/include/config.inc.php

And replace

Code: Select all

 $_config['masternode'] = false; 

with

Code: Select all

$_config['masternode'] = true;

Also add your public key between the quotes on the following setting

Code: Select all

$_config['masternode_public_key'] = '';

Next, send 100.010 ARO to the new wallet's address.

Wait for 4 confirmations and then run:

Code: Select all

cd /root/lightWalletCLI
./light-arionum-cli masternode create NODE-IP

Replace the NODE-IP with the actual IP of the node.

Search for:

Code: Select all

$_config['allowed_hosts'] = [
    '127.0.0.1',
];

Add your miner IP in the format:

Code: Select all

$_config['allowed_hosts'] = [
    '127.0.0.1',
    'MINER-IP'
];

You're done, the masternode is setup and it will start mining after 360 blocks.

I created a script to setup and manage your Arionum node on Ubuntu.
It's available on github here: https://github.com/KyleFromOhio/arionum-scripts

I wrote a tutorial on running a masternode here: http://aro.wiki/how-to-setup-an-arionum-masternode/
