Hyper Ledger 따라잡기

Hyper Ledger 개발환경 구성

Virtual Box

https://www.virtualbox.org/wiki/Downloads

VirtualBox platform package
VirtualBox Oracle VM VirtualBox Extension Pack

Ubuntu 18.04 LTS

Pre-install

https://www.ubuntu.com/download/desktop/thank-you?country=KR&version=18.04.1&architecture=amd64

VM 생성시 메모리 설정을 최소 2048M 이상 요구됨(HyperLedger Fabric 요구사항)
디스크 40Gb 이상
VM 설정 > 네트워크 > 어댑터 2 > 호스트 전용 어댑터

Install

우분투 설치 이미지를 사용하여 우분투 설치
설치 후 리부트
Guest 확장 CD 필요도구 설치

$ sudo apt-get install virtualbox-guest-dkms
$ sudo apt-get install linux-headers-virtual

Guest 확장 CD 설치 (장치 -> 게스트 확장 CD 이미지 삽입)

Go Lang 설치

Download 및 설치

$ sudo -i
# wget https://storage.googleapis.com/golang/go1.10.4.linux-amd64.tar.gz
# tar -xvf go1.10.4.linux-amd64.tar.gz

GOPATH/GOROOT 설정

# mkdir /root/gopath
# vi /etc/profile

/etc/profile 에 추가

export GOPATH=/root/gopath
export GOROOT=/root/go
export PATH=$PATH:$GOROOT/bin

환경설정 적용

# source /etc/profile

필요 소프트웨어 설치

apt-get install python-pip git curl libltdl-dev tree openssh-server net-tools

docker, docker-compose 설치

# wget https://download.docker.com/linux/ubuntu/dists/xenial/pool/stable/amd64/docker-ce_17.06.2~ce-0~ubuntu_amd64.deb
# dpkg -i docker-ce_17.06.2~ce-0~ubuntu_amd64.deb
# docker run hello-world
# pip install docker-compose
# docker-compose --version
docker-compose version 1.23.2, build 1110ad0

docker-compose 버전은 1.14.0 이상이면 OK

Hyper Ledfer Fabric 설치

HyperLedger Fabric 1.3 downad

# mkdir -p $GOPATH/src/github.com/hyperledger
# cd $GOAPTH/src/github.com/hyperledger
# git clone -b release-1.3 https://github.com/hyperledger/fabric

Hyperledger source compile

# cd fabirc
# make

환경변수 설정

# vi /etc/profile
export FABRIC_HOME=$GOPATH/src/github.com/hyperledger/fabric
export PATH=$PATH:$FABRIC_HOME/.build/bin

환경변수 적용

# source /etc/profile

작업 디렉토리 생성

# mkdir /root/worknet
# cd /root/worknet

시스템 기본 설정

# cp $FABRIC_HOME/sampleconfig/core.yaml /root/worknet/core.yaml
# cp $FABRIC_HOME/sampleconfig/orderer.yaml /root/worknet/orderer.yaml

환경설정

# vi /etc/profile
export FABRIC_CFG_PATH=/root/worknet
# source /etc/profile
