Dero Network Status

http://stats.atlantis.dero.live/

Prerequisites

You will find

• node-project : node side project
• apps.js : Entry of Server side & client side
• public : all the website file

Server Side

• NodeJS
• NPM
• MongoDB

Configuration

You need configure apps.js ; edit this file :

const API_KEY = ‘c3295d20321531f9207bbc435f04971c’; // This API is used to geolocate nodes during their first connection. 
const SERVER_PORT = 8080; // Port for express

and config.json for security check :

{
	"security": {
		"time_check": 30, // Time between every check security -- in minutes
		"topoheight": 8,
		"hash": "59521f49fbdd2c6a3cdaaff8c287ce408b0e437dbd622e1381640014fdcb9c78",
		"nonce": 2302413880
	},
	"nodes": {
		"refresh_time": 900 // Time between every daemon request -- in milliseconds
	}
}

Node Side

Configuration

Edit node-side.js and change :

const serverURL = 'http://54.37.72.72:8080/nodes'; // You need to change IP and PORT. You need to set same port like server side

Compile nodes-side

npm install pkg
pkg ./PATH/TO/node-side.js
You will find 3 compiled file : Windows, Linux and MacOS. If your system is 64 bits this compiled files will be for it.

Configuring for SSL Using Nginx

I use Nginx to proxy http(s) connections to the backend, while keeping nodes communicating with the backend on its own port, assumed here 8080

Make sure main Nodejs script is not on port 80 or 443, here we assume it’s on port 8080 Replace test.supportdero.com by intended domain name

In nginx you can have space seperated list (server_name test.supportdero.com test2.supportdero.com;) In cert bot similarly (sudo certbot --nginx -d test.supportdero.com -d test2.supportdero.com)

Install and configure nginx

sudo apt install nginx
sudo nano /etc/nginx/sites-available/default
Use the below as config

server {
    listen 80 default_server;
    listen [::]:80 default_server;
    root /var/www/html;
    server_name test.supportdero.com;
    location / {
            proxy_pass http://127.0.0.1:8080;
	}

Install certbot

sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install python-certbot-nginx
sudo certbot --nginx -d test.supportdero.com

Follow instructions and allow redirects, it will add SSL section to nginx config and force SSL redirects

Now to test and apply:

sudo nginx -t

If successful, proceed to reload nginx : sudo service nginx reload

Notes on multiple domain names

In nginx you can have space seperated list (server_name test.supportdero.com test2.supportdero.com;) In cert bot similarly (sudo certbot --nginx -d test.supportdero.com -d test2.supportdero.com)

Note on certificate renew

Let’s Encrypt’s certificates are only valid for ninety days. This is to encourage users to automate their certificate renewal process. The certbot package we installed takes care of this for us by running ‘certbot renew’ twice a day via a systemd timer. On non-systemd distributions this functionality is provided by a script placed in /etc/cron.d. This task runs twice a day and will renew any certificate that’s within thirty days of expiration.
