HOW TO INSTALL HYPER LEDGER FABRIC 2.0 IN UBUNTU 2022| BLOCKCHAIN

By Gwendolyn RobinsonNews

HYPER LEDGER FABRIC STEP BY STEP METHOD :-

Hyperledger Fabric is one of the leading enterprise blockchain platforms. Today we are going to learn how to install it on the latest version of ubuntu 20.04 LTS.

We will be installing the following:

Git

cURL

Docker and Docker Compose

Go Programming Language

Node.js Runtime and NPM

Python

Step 1: Create A New USER

Setup a new user, it’s good practice not to use root to install these software.

sudo adduser “name of new user”

Now we need to add our user to the sudo group.

sudo usermod -aG sudo “name of new user”

Switch to our newly created user:

su – “name of new user”

Step 2: Install Prerequisites

Install Git, cURL, docker, docker-compose, Node.js , NPM & Python

sudo apt-get update
sudo apt-get install git curl docker.io docker-compose nodejs npm python

Update NPM to 5.6.0 and Configure Docker

sudo npm install npm@5.6.0 -g

sudo usermod -a -G docker $USER

sudo systemctl start docker

sudo systemctl enable docker

Install and configure GoLang

wget https://dl.google.com/go/go1.13.6.linux-amd64.tar.gz tar
-xzvf go1.13.6.linux-amd64.tar.gz

#Move go to local

sudo mv go/ /usr/local

#Create a new folder go inside home

cd ~

mkdir go

#open

.bashrc pico ~/.bashrc

#go to the end of bashrc file and add the following:

export GOROOT=/usr/local/go export GOPATH= /home/”name of new user”/go export PATH=$PATH:$GOROOT/bin
#replace “name of new user” with your newly created user

Log out and Log back as a new user

su – “name of new user”

Step 3: Install Hyperledger Fabric Binaries, Docker Containers & Samples

curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/977ed80d3f3b4fe42dfb8f04cc93a92ab75b709e/scripts/bootstrap.sh | bash -s 2.0.0

Step 4: Test The Installation

To make sure that everything works fine, you can deploy a test network by using scripts that are provided in the fabric-samples repository. The test network is provided for learning about Fabric by running nodes on your local machine. Developers can use the network to test their smart contracts and applications. The network is meant to be used only as a tool for education and testing and not as a model for how to set up a network.

Navigate to the test network directory by using the following command:

cd fabric-samples/test-network

In this directory, you can find an annotated script, network.sh, that stands up a Fabric network using the Docker images on your local machine. You can run ./network.sh -h to print the script help text:

From inside the test-network directory, run the following command to remove any containers or artifacts from any previous runs:

./network.sh down

You can then bring up the network by issuing the following command. You will experience problems if you try to run the script from another directory:

./network.sh up

This command creates a Fabric network that consists of two peer nodes, one ordering node. No channel is created when you run ./network.sh up, though we will get there in another guide. If the command completes successfully, you will see the logs of the nodes being created:

Check if all the docker containers are running:

docker ps -a

Clean the Network

./network.sh down

Congratulations! You Have Successfully Installed Hyperledger Fabric In Your Machine.
