Before understanding how Install Hyperledger Fabric in Ubuntu , please try to understand what exactly is block chain and what are the prerequisite required.
Blockchain is finally making rounds around the globe. Initially started with Bitcoin , followed by many crypto currencies often refer as altcoin. Many people still believes that blockchain is all about Bitcoin and currency.
But Block Chain has many other applications and it can bring decentralization and transparency in every application or service we use.
Many organization and understood the importance of BlockChain and supporting platforms were launched to implement blockchain applications. Hyper Ledger Fabric is the a platform to developed and deploy Block Chain application/smart contract in Permission-ed network without requiring any sort of Crypto Currencies.
Techaorha Team in India (Mumbai) helps corporate and government to implement block chain application in their existing application make it more secure and transparent.
To Install Hyperledger Fabric in Ubuntu following componenets are required. Here is list. Steps required to install other components is detailed below that
Hyperledger requires some package to run the network, You must installing following dependencies to get started.
curl to Install Hyperledger Fabric in Ubuntu. INstall curl using following commands in Ubuntu
# command to install curl in ubuntu
sudo apt-get install curl
Python is require for running hyperledger. Below command will install python 2.7 , which is the required version of hyper ledger.
# Command to install python
sudo apt-get install python
Hyperledger requires docker 17.06.2-ce or greater. So if you install docker from ubuntu packages it may not work as required.
Follow the below commands to install Docker in Ubuntu for HyperLedger.
#update the package index with the following command
sudo apt-get update
#install packages to help wiht Docker Installation in Ubuntu
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
# Add docker gpg key curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add –
# Verify the key in Ubuntu with Following Command
sudo apt-key fingerprint 0EBFCD88
#add repository to Ubuntu System with following command to Install Docker for Hyper ledger
sudo add-apt-repository “deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable”
#again update the packages
sudo apt-get update
#install the specific version of Docker for Hyperledger installation.
sudo apt-get install docker-ce=18.03.0~ce-0~ubuntu
# download docker-compose
sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
#Apply executable to the binary
sudo chmod +x /usr/local/bin/docker-compose
#check docker composeversion
GO lang is high level language developed by Google. Many applications are written in Go-Language. Go-Lang is required to program logic and smart contracts in Hyperledger
Follow below step to install go-lang in Ubuntu
#Download go-lang tar file using curl with the help of below commands
curl -O https://storage.googleapis.com/golang/go1.9.3.linux-amd64.tar.gz
#verify the code is from authentic source using below command
#Extract the tar file in any folder
tar -xvf go1.9.3.linux-amd64.tar.gz
#move the go directory to usr/local using the following command
sudo mv go /usr/local
#open profile using below command
sudo vim ~/.profile
#following lines to ~/.profile file
#reload the file using following command
source ~/.profile #thanks.
Node Js is script based programming language. NodeJs is required by Hyperledger fabric to program logic and write contracts. This can also be used to developed front-end with the help of angularjs framework.
For Hyper Ledger NodeJs version are limited. Hyperledger fabric does not support NodeJs 9.x and its requires NodeJs above 8.9.x , so here you see option are very limited and the best to to install node js is via source code.
Follow below steps to install hyperleger one by one.
#update ubuntu package
sudo apt-get update
#install build essentials
sudo apt-get install build-essential openssl libssl-dev pkg-config
# change to source directory
cd /usr/local/src #create node directory sudo mkdir node
#enter into directory
#download node js version 8.9.3 using following command
sudo wget https://nodejs.org/dist/v8.9.3/node-v8.9.3.tar.gz
#Extract the tar file
sudo tar zxvf node-v8.9.3.tar.gz
#change to extracted nodejs directory
#Configure the Directory
# Run Make
sudo make install
#don’t forget to check the version using following commands
#download fabric example
curl -sSL http://bit.ly/2ysbOFE | bash -s 1.2.0-rc1
Testing. To make sure everything is install as required. Lets run and create your first network on HyperLedger Fabric
Generate the Genesis block of Your Network
sudo ./byfn.sh generate
Start Your Network
#Start Your Network
sudo ./byfn.sh up
If every things goes well , stop your network
sudo ./byfn.sh down
