Hyperledger Fabric is one of the leading enterprise grade blockchain platforms. In this article we will cover Prerequisites and Hyperledger Fabric v2.4 installation on Linux Ubuntu 20.04 LTS.

Step 1: Install curl, git

Install the latest version of git and curl if it is not already installed.

sudo apt update
sudo apt-get install git
sudo apt-get install curl

Step 2: Install Docker

Install the latest version of Docker if it is not already installed.

sudo apt-get -y install docker-compose

Once installed, confirm that the latest versions of both Docker and Docker Compose executables were installed.

docker --version
Docker version 20.10.12, build 20.10.12-0ubuntu2~20.04.1

docker-compose --version
docker-compose version 1.25.0, build

Make sure the Docker daemon is running.

sudo systemctl start docker

Optional: If you want the Docker daemon to start when the system starts, use the following:

sudo systemctl enable docker

Add your user to the Docker group.

sudo usermod -a -G docker <username>

Step 3: Install Golang

curl -O https://dl.google.com/go/go1.18.3.linux-amd64.tar.gz
tar xvf go1.18.3.linux-amd64.tar.gz
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin

Now, you have to open and edit you **bashrc **file. In most cases, the bashrc is a hidden file that lives in your home directory.

nano ~/.bashrc

Add following two lines, at the end of the file:

export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin

Create new directory where you will install Hyperledger Fabric

mkdir fabric-network

Step 4: Install Hyperledger Fabric

To download a specific release, pass a version identifier for Fabric and Fabric CA Docker images. The command below demonstrates how to download the latest production releases - Fabric v2.4.4 and Fabric CA v1.5.3

curl -sSL https://bit.ly/2ysbOFE | bash -s -- <fabric_version> <fabric-ca_version>

curl -sSL https://bit.ly/2ysbOFE | bash -s -- 2.4.4 1.5.3

Download the latest release of Fabric samples, docker images, and binaries.

curl -sSL https://bit.ly/2ysbOFE | bash -s

Congrats, you have installed Hyperledger Fabric with all dependencies.

To test the our installation, we will run test network that comes with fabric-samples

cd fabric-samples/test-network
./network.sh up createChannel -ca -c mychannel -s couchdb

The above command will create a channel(mychannel) with certificate Authorities and bring up couch-db as state database.

Using following Docker command we can check all running containers

docker ps -a

You should be able to see the containers up and running.

Congratulations, you have installed and setup Hyperledger Fabric.
