Install - nix

Preliminaries for using nix

For a dev environment with nix package manager a postgres install on the base system is required, this guide does not cover a postgresql server running with nix-shell.

Set up PostgreSQL

sudo -u postgres createdb lamassu
sudo -u postgres psql postgres

In psql, run the following and set password to postgres123:

\password postgres
ctrl-d

Starting up environment

shell.nix script provided, all you need to do to setup the environment is to run nix-shell on the folder.

Installation

Install node modules

Make sure you're running NodeJS 8.3 or higher. Ignore any warnings.

npm install

Generate certificates

bash tools/cert-gen.sh

Notes:

  • This will create a .lamassu directory in your home directory.

Set up database

Important: lamassu-migrate currently gripes about a QueryResultError. Ignore this, it works anyway.

node bin/lamassu-migrate

Run new-lamassu-admin

cd new-lamassu-admin/
npm install
npm run start

Run lamassu-admin-server

In a second terminal window:

node bin/lamassu-admin-server --dev

Register admin user

In a third terminal window:

node bin/lamassu-register [email protected] superuser

You'll use this generated URL in the brower in a moment.

Complete configuration

Paste the URL from lamassu-register exactly as output, into a browser (chrome or firefox).

Important: the host must be localhost. Tell your browser to trust the certificate even though it's not signed by a recognized CA. If you get an "expired" error, try opening https://localhost:8070/graphql in another tab and trust the certificate.

Go to all the required, unconfigured red fields and choose some values. Choose mock services whenever available.

Run lamassu-server

node bin/lamassu-server --mockScoring

Add a lamassu-machine

Click on + Add Machine in the sidebar. Type in a name for your machine and click Pair. Open up development tools to show the JavaScript console and copy the totem. You will use this to run lamassu-machine. This pairing totem expires after an hour.

Now continue with lamassu-machine instructions from the INSTALL.md file in lamassu-machine repository.

Subsequent runs

To start the Lamassu server run:

node bin/lamassu-server --mockScoring

To start the Lamassu Admin run:

node bin/lamassu-admin-server --dev

and

cd new-lamassu-admin/
npm run start
