Windows PC에 가상머신을 생성하고 Ubuntu를 설치한 상태에서 아래 문서를 따라하면서 실습을 하였습니다.
이 문서를 작성하면서 사용한 소프트웨어 버전을 각각의 소프트웨어 이름 옆에 표시하였습니다.
실습 환경
- Windows 10
- Oracle VM VirtualBox 6.1.6
- 가상 머신 생성
- 이름:
ubuntu-fabric - 메모리 크기:
4GB - 저장소 크기:
40GB (10GB로 하면 금방 부족해짐)
- 이름:
- 가상 머신 생성
- Ubuntu Desktop 20.04 LTS
1. 준비 사항
Git 2.17.1
sudo apt-get install git
cURL 7.58.0
sudo apt-get install curl
Docker 19.03.8
아래 문서를 참고하여 Docker를 설치합니다.
설치 방법으로 Install using the repository을 택하여 진행하였습니다.
-
SETUP THE REPOSITORY
-
apt가 HTTPS를 통하여 저장소를 사용할 수 있도록 패키지 추가$ sudo apt-get update $ sudo apt-get install \ apt-transport-https \ ca-certificates \ curl \ gnupg-agent \ software-properties-common -
Docker의 GPG 키 추가
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - -
stable 저장소 설정
$ sudo add-apt-repository \ "deb [arch=amd64] https://download.docker.com/linux/ubuntu \ $(lsb_release -cs) \ stable"위 명령 줄에서
$(lsb_release -cs)는focal을 반환합니다. 이로 인해 명령이 실패로 끝나게 되는데 이는 Docker가 아직focal을 지원하지 않아서 발생하는 문제입니다. 이를 해결하기 위하여$(lsb_release -cs)을 Ubuntu 18.04 LTS의 배포명인bionic으로 대체해서 실행합니다.$ sudo add-apt-repository \ "deb [arch=amd64] https://download.docker.com/linux/ubuntu \ bionic \ stable"
-
-
INSTALL DOCKER ENGINE
-
Docker 엔진과 containerd 최신 버전 설치
$ sudo apt-get update $ sudo apt-get install docker-ce docker-ce-cli containerd.io
-
이제 Docker 엔진을 설치하였습니다. 이에 더하여 Post-installation steps for Linux 문서가 제시하는 몇 가지 작업을 수행하면 Docker를 좀 더 편리하게 사용할 수 있습니다.
-
Manage Docker as a non-root user
$ sudo usermod -aG docker $USER주의: 위의 명령에서
-a없이-G옵션만 사용하면 사용자의 기존 그룹들은 모두 제거되고 새로 지정한docker그룹만 추가됩니다.가상머신 환경에서 그룹 멤버십을 적용하려면 가상머신을 다시 시작해야 합니다.
-
Configure Docker to start on boot
$ sudo systemctl enable docker
docker-compose 1.17.1
sudo apt-get install docker-compose
Go Programming Language 1.14.2
위 문서를 참고하여 아래와 같이 Go를 설치합니다.
-
배포 파일 go1.14.2.linux-amd64.tar.gz 다운로드
-
다운로드한 파일을
/usr/local폴더에 풀기sudo tar -C /usr/local -xzf go$VERSION.$OS-$ARCH.tar.gz -
Go의
bin폴더를PATH환경변수에 추가하기export PATH=$PATH:/usr/local/go/bin
Node.js 12.16.2 & NPM 6.14.4
위 문서를 참고하여 아래와 같이 Node.js를 설치합니다. NPM은 Node.js와 함께 설치됩니다.
-
배포 파일 node-v12.16.3-linux-x64.tar.xz 다운로드
-
다운로드한 파일을
/usr/local/lib/nodejs폴더에 풀기sudo mkdir -p /usr/local/lib/nodejs sudo tar -xJvf node-v12.16.3-linux-x64.tar.xz -C /usr/local/lib/nodejs -
Node.js의
bin폴더를PATH환경변수에 추가하기export PATH=$PATH:/usr/local/lib/nodejs/node-v12.16.3-linux-x64/bin -
Fabric 코드 저장용 Go 작업공간을 위한
GOPATH환경변수 추가export GOPATH=$HOME/go
Python 2.7
Fabric Node.js SDK는 npm install을 성공적으로 마치기 위하여 Python 2.7을 필요로 합니다.
sudo apt-get install python
2. 샘플 파일, 실행 파일, 도커 이미지 설치
1. 작업 폴더 생성
파일을 다운로드하여 저장할 폴더를 만듭니다. 폴더 이름을 아래 예시와 다르게 지어도 됩니다.
mkdir Hyperledger
cd Hyperledger
2. 스크립트 실행
아래 명령으로 스크립트 파일을 다운로드하고 실행합니다.
curl -sSL https://bit.ly/2ysbOFE | bash -s
위 명령은 아래의 작업들을 수행합니다.
- If needed, clone the hyperledger/fabric-samples repository
- Checkout the appropriate version tag
- Install the Hyperledger Fabric platform-specific binaries and config files for the version specified into the /bin and /config directories of fabric-samples
- Download the Hyperledger Fabric docker images for the version specified
실행 명령들을 실행 경로에서 찾을 수 있도록 아래 환경 변수를 설정합니다.
export PATH=$PATH:$HOME/Hyperledger/fabric-samples/bin
3. Using the Fabric test network
1. 테스트 네트워크 실행
cd $HOME/Hyperledger/fabric-samples/test-network
./network.sh up
위 명령이 정상적으로 실행되면 아래와 같은 메시지가 출력됩니다.
Starting nodes with CLI timeout of '5' tries and CLI delay of '3' seconds and using database 'leveldb'

2. 채널 생성
./network.sh createChannel
위 명령을 수행하면 이름이 mychannel인 채널을 생성합니다. 출력 메시지는 아래와 같습니다.
Creating channel 'mychannel'.

4. 체인코드 호출
peer 명령을 사용하여 아래 작업들을 수행할 수 있습니다.
- invoke deployed smart contracts
- update channels
- install and deploy new smart contracts
peer 명령을 실행 경로에서 찾을 수 있도록 아래 환경 변수를 설정합니다.
export PATH=${PWD}/../bin:${PWD}:$PATH
core.yaml 파일을 찾을 수 있도록 아래 환경 변수를 설정합니다.
export FABRIC_CFG_PATH=$PWD/../config/
peer CLI를 Org1으로 동작시키기 위하여 아래 환경 변수들을 설정합니다.
# Environment variables for Org1
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
export CORE_PEER_ADDRESS=localhost:7051
아래 명령을 사용하여 채널에서 자동차 목록을 가져옵니다.
peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}'
자동차 소유자를 변경하기 위하여 아래 명령을 실행합니다.
peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls true --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n fabcar --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"function":"changeCarOwner","Args":["CAR9","Dave"]}'
peer CLI를 Org2로 동작시키고자 한다면 아래 환경 변수들을 설정합니다.
# Environment variables for Org2
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
export CORE_PEER_ADDRESS=localhost:9051
5. 테스트 네트워크 종료
아래 명령으로 테스트 네트워크를 내릴 수 있습니다.
./network.sh down
위 명령은 아래 항목들을 제거합니다.
- the node and chaincode containers
- the organization crypto material
- the chaincode images from your Docker Registry
- the channel artifacts and docker volumes
6. 다음 단계
- Bring up the network with Certificate Authorities
- What’s happening behind the scenes?
- Troubleshooting
