Welcome, everyone! In this tutorial, we will deploy and start up a crypto trading platform from scratch using OpenDAX on Digital Ocean.

OpenDAX is an open-source cloud-native multi-service platform for building a Blockchain/FinTech exchange of digital assets, cryptocurrency and security tokens. The Crypto exchange software is developed at Openware.

So let’s get into it.

For Production setup, get extra-large VPS from Gavedu, which boasts

1. A 10 core CPU
2. 60 GB RAM
3. 1.6 TB Intel Optane SSD

System Requirements: Considering Ubuntu 20.04

Login to your server via SSH and follow the steps bellow, it will collect all the requirements and setup your server for OpenDAX

1. Create a file setup.sh and paste content bellow:

sudo nano ~/setup.sh

#!/bin/bash -x

COMPOSE_VERSION="1.23.2"
COMPOSE_URL="https://github.com/docker/compose/releases/download/$COMPOSE_VERSION/docker-compose-$(uname -s)-$(uname -m)"

# Opendax bootstrap script
install_core() {
  sudo bash <<EOS
apt-get update
apt-get install -y -q git tmux gnupg2 dirmngr dbus htop curl libmariadbclient-dev-compat build-essential
useradd -m -G root app
EOS
}

log_rotation() {
  sudo bash <<EOS
mkdir -p /etc/docker
echo '
{
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "10m",
    "max-file": "10"
  }
}' > /etc/docker/daemon.json
EOS
}

# Docker installation
install_docker() {
  curl -fsSL https://get.docker.com/ | bash
  sudo bash <<EOS
usermod -a -G docker $USER
curl -L "$COMPOSE_URL" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
EOS
}

install_ruby() {
  sudo -u app bash <<EOS
  gpg2 --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
  curl -sSL https://get.rvm.io | bash -s stable
EOS

}

install_core
log_rotation
install_docker
install_ruby.

Save the file and make it executable

chmod +x setup.sh

run the file

./setup.sh

Once the process it completed, your server is ready to go and we can clone OpenDAX

git clone https://github.com/openware/opendax.git
cd opendax
bundle install

Configure the installation and start it up

To configure the installation open the main configuration file config/app.yml and make necessary changes.

nano config/app.yml

# Configure domain and subdomain

  machine_type: "n1-standard-4"
  image: "debian-cloud/debian-9"

After all the configuration is in place, we’re ready to GO-Live!

It’s as easy as running a simple command:

rake service:all

This command will take a while to execute since every image has to be pulled and started up, so be patient, once everything is up and running, you will be to access the exchange at http://testdeploy.gavedu.com it will look something like this

A fully functional crypto trading platform in 15 minutes, following simple steps. In the next tutorial, we’ll customize the frontend page with our own logo to make it more personal and make open source mobile application, https://github.com/colombo-77/OpenDAX
