Step 2. Install cURL
sudo apt install curl
Step 2. Check curl version
curl --versionOutput
curl 7.58.0 (x86_64-pc-linux-gnu) libcurl/7.58.0 OpenSSL/1.1.1 zlib/1.2.11 libidn2/2.0.4 libpsl/0.19.1 (+libidn2/2.0.4) nghttp2/1.30.0 librtmp/2.3

Docker
Step 1. Update the package list
sudo apt-get updateStep 2. Install the required packages
sudo apt-get install apt-transport-https ca-certificates gnupg-agent software-properties-common
Step 3. Add Docker’s official GPG key:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
Step 4. Setup the Docker stable repository
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
Step 5. Update the package list
sudo apt-get updateStep 6. Install the latest version of Docker engine
sudo apt-get install docker-ce docker-ce-cli containerd.io
Step 7. Add user to Docker group
In order to run the docker commands without sudo, you need to add the current user to the docker group with the below command.
sudo usermod -aG docker $USERTo confirm if the user is added to docker group, try the command
id -nGOutput
jay adm cdrom sudo dip plugdev lpadmin sambashare docker
Step 8. Check Docker version
jay@hlf-dev:~$ docker --version
Docker version 19.03.8, build afacb8b7f0
jay@hlf-dev:~$
Step 9. Verify the Docker Engine
The below command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits.
docker run hello-world
Install Docker Compose
Step 1. Download the latest version of the Docker Compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.25.5/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
Step 2. Apply executable permissions to the binary
sudo chmod +x /usr/local/bin/docker-composeStep 3. Check Docker Compose version
jay@hlf-dev:~$ docker-compose --version
docker-compose version 1.25.5, build 8a1c60f6
jay@hlf-dev:~$
Install Go
The recommend version of Go is version 1.12.x.
Step 1. Download the tar file
curl -O https://storage.googleapis.com/golang/go1.12.9.linux-amd64.tar.gzStep 2. Extract the tar file
tar -xvf go1.12.9.linux-amd64.tar.gzStep 3. Move the go directory
sudo mv go /usr/localStep 4. Update environment variables
We need to update environment variables i.e. PATH and GOPATH. For this the user’s profile needs to be updated.
nano ~/.profileAdd the below in the .profile file.
export GOPATH=$HOME/go
export PATH=$PATH:/usr/local/go/bin:$GOPATH/binSave the .profile file and load the updated environment variables.
source ~/.profileStep 5. Check go version
jay@hlf-dev:~$ go version
go version go1.12.9 linux/amd64
jay@hlf-dev:~$
Install Node.js and NPM
If you will be developing applications for Hyperledger Fabric leveraging the Hyperledger Fabric SDK for Node.js, version 8 is supported from 8.9.4 and higher. Node.js version 10 is supported from 10.15.3 and higher.
We will be installing 10.x version. Installing Node.js will also installs NPM
Step 1. Install the Node.js v10.x repository
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
Step 2. Install nodejs
sudo apt-get install -y nodejsStep 3. Check node version
jay@hlf-dev:~$ node -v
v10.20.1
jay@hlf-dev:~$
Step 4. Check NPM version
jay@hlf-dev:~$ npm -v
6.14.4
jay@hlf-dev:~$
Install Hyperledger Samples, Binaries and Docker Images
Under Fabric 1.4.x releases, v 1.4.7 is the latest release and we will install this version.
Step 1. Before downloading the Fabric binaries, create a directory for e.g. hyperledger in your home path.
mkdir hyperledger
cd hyperledger/Step 2. Download Fabric v1.4.7
From the hyperledger directory (for e.g. /home/jay/hyperledger) run the below command. Please note, this will take quite sometime based on your internet speed.
curl -sSL http://bit.ly/2ysbOFE | bash -s -- 1.4.7 1.4.7 0.4.20
Step 3. Update environment variable
nano ~/.profileAdd the fabric bin path to the PATH variable. Please make sure to use the path where you have downloaded fabric binaries.
export PATH=/home/$USER/hyperledger/fabric-samples/bin:$PATHSave the .profile file and load the updated environment variables.
source ~/.profileTesting the Hyperledger Fabric installation
Fabric comes with few fabric samples which can be used to test the fabric installation.
Step 1. Change directory to the first-network directory
cd /home/$USER/hyperledger/fabric-samples/first-networkStep 2. Use the script to bring up the network.
./byfn.sh up
In case you are wondering, byfn stands for Build Your First Network. Refer here for further details.
Step 3. Verify the Docker containers
docker ps -a
Step 4. Bring down the network
./byfn.sh downThis concludes the steps required to setup Hyperledger Fabric v1.4 in Ubuntu 18.04.3 LTS.
