Guide: install Sphinx-relay on myNode.

This guide is focused on installing Sphinx-relay on top of myNode. Information about myNode can be found at: https://mynodebtc.com/.

Preparations

Be able to connect with your node through SSH.
Make sure you are running LND version 0.9.0 or higher. This can be seen at http://mynode.local/lnd at the right top. Or by inserting the following console command:

$ lncli getinfo
> "version": "0.9.0-beta commit=v0.9.0-beta"

Open port 3001/TCP on your router. How to do this is not included in this guide. https://www.yougetsignal.com/tools/open-ports/ is one of the many websites that can be used to check if a port is opened on your network.

Let's Start

Open port 3001 on myNode

Open up a console window with SSH. And log in as root

$ sudo su

Open up port 3001 on your machine and make sure it has been added to the list.

$ ufw allow 3001 comment 'allow Sphinx-Chat'
$ ufw status

> Status: active
>
> To                         Action      From
> --                         ------      ----
> 3001 (v6)                  ALLOW       Anywhere (v6)              # Sphinx-Chat

Download

$ sudo su bitcoin
$ cd

Clone the repository from Github and install the package.

$ git clone https://github.com/stakwork/sphinx-relay
$ cd sphinx-relay
$ npm install

Dependencies

sqlite3: $ apt-get install sqlite3

Configure

Edit the "production" section of config/app.json.

$ cd
$ cd sphinx-relay/config/
$ nano app.json

Change the following 4 lines to:

"macaroon_location": "/home/bitcoin/.lnd/data/chain/bitcoin/mainnet/admin.macaroon",
"tls_location": "/mnt/hdd/mynode/lnd/tls.cert",
"lnd_log_location": "/home/bitcoin/.lnd/logs/bitcoin/mainnet/lnd.log",
"lncli_location": "/home/bitcoin/go/bin",

Save and exit: Ctrl + X

Y

Enter

Edit the "production" section of config/config.json

$ nano config.json

Change to following line to:

"storage": "/home/bitcoin/sphinx.db"

Save and exit: Ctrl + X

Y

Enter

To connect to your app: (replace x.x.x.x with your IP)

$ cd
$ cd sphinx-relay/config/
$ export NODE_IP=x.x.x.x:3001

For extra security:

$ export USE_PASSWORD=true

Activate keysend

We need LND to run with keysend activated. First we check if it is already activated on your node. To do that. Go to http://mynode.local/lnd/config and check if the line accept-keysend=1 is included somewhere in the text.

If accept-keysend=1 is already included you can continue without changing anything. If accept-keysend=1 is not included, add it to a new line and click the Save button. This will restart your device. (Restarting could take up to several minutes but also hours, so be patient.)

Run

Now it's time to run the software.

$ cd
$ cd sphinx-relay/config/
$ npm run prod

When Relay starts up, it will print a QR in the terminal. You can scan this in your app (Android or iOS) to connect!
