Install Hyperledger Fabric in Ubuntu 20.04 LTS

Hyperledger Fabric is one of the leading enterprise blockchain platforms. When I started learning Fabric a year ago, I struggled a lot through the installation process.  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:

1. Git
2. cURL
3. Docker and Docker Compose
4. Go Programming Language
5. Node.js Runtime and NPM
6. Python

Step 1: Create a new USER

It is always a smart idea not to use root to install these softwares.  Let us create a new user.

sudo adduser bibek

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

sudo usermod -aG sudo bibek

Switch to our newly created user:

su - bibek

Step 2: Install Prerequisites

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

  sudo apt-get update
  sudo apt-get install git 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/bibek/go
   export PATH=$PATH:$GOROOT/bin
  
   #replace bibek with your newly created user

• Log out and Log back as a new user
  

  exit
  su - bibek

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

 curl -sSL http://bit.ly/2ysbOFE | bash -s 1.4.4
 #You can replace 1.4.4 with 2.0.0 if you want to install Fabric 2.0.0

You will find a new folder called fabric-samples inside your home folder.

Step 4: Test the Installation

To make sure that everything works fine we will run a pre-built script called "Build Your First Network or BYFN" that will test if you have everything installed correctly or not. 

 cd fabric-samples/first-network
 ./byfn.sh generate
 ./byfn.sh up

You should get something like below at the end of execution if everything went right. If not you may have made a mistake in the installation process. 

========= All GOOD, BYFN execution completed =========== _____ _ _ ____ | ____| | \ | | | _ \ | _| | \| | | | | | | |___ | |\ | | |_| | |_____| |_| \_| |____/   

Check if all the docker containers are running:

docker ps -a

Clean the Network

./byfn.sh down

Congratulations ! You have successfully installed Hyperledger Fabric in your machine.
I will talk about how to code, compile and test your chaincode in the next article.

Cheers.
