Blockchain technology has taken the world by storm, with its decentralized and secure nature making it ideal for various applications. If you’re looking to get started with blockchain technology and want to set up your own blockchain network, you may be interested in installing it on an Ubuntu operating system. In this blog, we’ll walk you through the process of installing Blockchain on Ubuntu.
Before we begin, it’s important to note that there are many different blockchain platforms to choose from, and each one may have a slightly different installation process. For the purpose of this tutorial, we’ll be using the popular open-source platform, Hyper-ledger Fabric.
Step 1: Install Ubuntu
If you haven’t already, the first step is to install Ubuntu on your computer. You can either download the ISO image from the official Ubuntu website and create a bootable USB drive, or you can use the Ubuntu live CD to try out the operating system without installing it.
Step 2: Update Ubuntu
Once you have Ubuntu installed, you need to update it to the latest version. Open the terminal and run the following command:
sudo apt update
sudo apt upgrade
Step 3: Install Docker and Docker Compose
Hyper-ledger Fabric runs on Docker containers, so you need to install both Docker and Docker Compose to get started. Docker Compose is a tool for defining and running multi-container Docker applications. To install Docker and Docker Compose, run the following commands in the terminal:
sudo apt install docker.io
sudo apt install docker-compose
Step 4: Install Go Programming Language
Hyper-ledger Fabric is built using the Go programming language, so you need to install it on your system. You can install Go by following the instructions on the official Go website.
Step 5: Install Hyper-ledger Fabric
To install Hyper-ledger Fabric, you first need to clone the repository from GitHub. In the terminal, run the following command:
git clone https://github.com/hyperledger/fabric.git
This will download the latest version of Hyper-ledger Fabric to your system.
Step 6: Set up the Network
Next, you need to set up the network by creating a network configuration file and running the network.
First, create a network configuration file using the sample network configuration provided in the Hyper-ledger Fabric repository. You can find the sample network configuration in the /fabric/sample config directory.
Next, run the following command in the terminal to start the network:
cd fabric/
./byfn.sh generate
./byfn.sh up
This will start the network and create the necessary Docker containers.
Step 7: Test the Network
To test the network, you can run a sample application to see if everything is working properly. The sample application is provided in the Hyperledger Fabric repository and can be found in the /fabric/examples directory.
To run the sample application, run the following command in the terminal:
cd examples/
node app.js
This will start the sample application and connect to the network. You should see a message indicating that the network is working properly.
Step 8: Clean Up
When you’re finished testing the network, it’s important to clean up the Docker containers to avoid any issues with future installations. To do this, run the following command in the terminal:
cd fabric/
./byfn.sh down
