2. 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.

3. Prerequisites for this Meetup
Linux or a Mac
Internet and Web access
Discuss Windows vs Linux support
Q + A on getting Linux versions, VMs Docker, Mac

4. 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

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

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

7. cURL cURL lets command line commands copy files from web page URLs.
Test if you already have it before installing
curl --version
Mine was v7.47.0, latest is , no need to upgrade

8. 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- | bash export NVM_DIR="${XDG_CONFIG_HOME/:-$HOME/.}nvm“ [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
nvm install v nvm use v nvm alias default v8.14.0
Node.js
NPM - Node Package Manager
NVM - Node Version Manager:

9. Go – Google Golang programming language
go version (HL v1.4 requires )
cd ~
mkdir GoTest
curl > go linux-amd64.tar.gz
sudo tar -xvf go 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)

10. gRPC / Node.js gRPC Library
Google RPC
npm install --global grpc

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

12. 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

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

14. Docker Compose https://docs.docker.com/compose
Docker Compose version or greater
docker-compose --version

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

16. 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 1.3/scripts/bootstrap.sh | bash -s 1.3.0
Install takes about 3.5GB of disk space
export PATH=~/fabric-samples/bin:$PATH

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

18. fabric-samples/bin folder contents
configtxgen - create and inspect channel config related artifacts
configtxlator - translate between protobuf and JSON versions of fabric data structures and create config updates
cryptogen - utility for generating Hyperledger Fabric key material
discover - interact with discovery service, discover peers and orderers
