Hyperledger Fabric and Composer Install For Hyperledger Seattle Meetup Ray Metz, Seattle Blockchain Training 12/13/2018 This file location: http://seattleblockchaintraining.com/courseOutlines.html

Goals To have your own Hyperledger Fabric blockchain with no dependency on IBM cloud or public Internet To have a working Composer developer environment hosted on your laptop, pointed to your own blockchain. To Practice installing on your own. Knowledge of how to install. An opportunity to ask questions. Knowledge of how easy or hard it is to install. Knowledge of install components.

Prerequisites for this Meetup Linux or a Mac Internet and Web access https://hyperledger-fabric.readthedocs.io/en/latest/prereqs.html Discuss Windows vs Linux support Q + A on getting Linux versions, VMs Docker, Mac

Linux Requirements and Version Local VM CPU / Memory / Disk requirements Update commands sudo apt-get update sudo apt-get upgrade Commands to learn your Linux version: uname -a lsb_release -a cat /etc/*release cat /etc/issue* cat /proc/version

Check memory and disk space I upgraded to 2GB. free top Disk I upgraded to 16GB. df docker system df

Summary of pre-install software Linux: verify your version and latest version curl --version (mine was v7.47.0, latest is 7.62.0) node -v (v8.14.0) npm -v (mine was 6.4.1) go version (mine is 1.11.2) grpc (version test not known) python --version (mine is 2.7.12) git --version (latest is 2.20, mine is 2.7.4) docker --version (mine is 18.09) docker-compose --version (mine is 1.23.1)

cURL cURL lets command line commands copy files from web page URLs. Test if you already have it before installing curl --version https://curl.haxx.se/download.html Mine was v7.47.0, latest is 7.62.0, no need to upgrade

Node.js, NPM, NVM Node is JavaScript without a web browser. An updated shell script, web server, and more Node 8.9 or higher, (Node 9.x and 10.x is not supported at this time) Check your versions with: node -v npm -v (mine is npm v6.4.1 from node v8.14) nvm --version curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash export NVM_DIR="${XDG_CONFIG_HOME/:-$HOME/.}nvm“ [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm nvm install v8.14.0 nvm use v8.14.0 nvm alias default v8.14.0 Node.js https://nodejs.org/en/ NPM - Node Package Manager NVM - Node Version Manager: https://github.com/creationix/nvm https://github.com/creationix/nvm#installation

Go – Google Golang programming language go version (HL v1.4 requires 1.11.2) https://golang.org/ cd ~ mkdir GoTest curl https://dl.google.com/go/go1.11.2.linux-amd64.tar.gz > go1.11.2.linux-amd64.tar.gz sudo tar -xvf go1.11.2.linux-amd64.tar.gz sudo mv go /usr/local export GOROOT=/usr/local/go export GOPATH=$HOME/GoTest export PATH=$GOPATH/bin:$GOROOT/bin:$PATH vi .profile (add three export statements to bottom for autorun) sudo apt-get install golang-go (installs an old version) which go (command to show your go folder)

gRPC / Node.js gRPC Library Google RPC https://github.com/grpc/grpc npm install --global grpc

Python Verify Python v2.7 (not 3.5.1) python -V sudo apt install python-minimal

git https://git-scm.com/ git --version (latest is 2.20, mine is 2.7.4) git config --get core.autocrlf needs to be false git config --get core.longpaths needs to be true Run if you need to change them: git config --global core.autocrlf false git config --global core.longpaths true

Docker https://www.docker.com/ Docker version 17.06.2-ce or greater (HL v1.4: v18.06 or higher) docker --version docker version sudo chmod 777 /var/run/docker.sock https://store.docker.com/search?type=edition&offeri ng=community Check data location. Should be in a writable location such as /Users, /Volumes, /private, or /tmp

Docker Compose https://docs.docker.com/compose https://docs.docker.com/compose/install/#install-compose Docker Compose version 1.14.0 or greater docker-compose --version

Summary - Verify all versions Linux: verify your version and latest version curl --version (mine was v7.47.0, latest is 7.62.0) node -v (v8.14.0) npm -v (mine was 6.4.1) go version (mine is 1.11.2) grpc (version test not known) python --version (mine is 2.7.12) git --version (latest is 2.20, mine is 2.7.4) docker --version (mine is 18.09) docker-compose --version (mine is 1.23.1)

Install Fabric Decide the location where you are installing Class will use ~/fabric-samples or /home/yourlogin/fabric-samples cd ~ Install fabric-samples: curl –ssl https://raw.githubusercontent.com/hyperledger/fabric/release- 1.3/scripts/bootstrap.sh | bash -s 1.3.0 Install takes about 3.5GB of disk space export PATH=~/fabric-samples/bin:$PATH

Fabric Samples Summary version 1.3.0 platform specific fabric binaries version 1.3.0 platform specific fabric-ca-client binary Docker Images peer orderer ccenv tools ca couch kafka zookeeper
