      How to Dev 2020. 12. 29. 14:33

      hyperleder backup and restore

      fabric data backup

      1. crypto material (crypto-config)
      2. Channel artifacts (channel-artifacts folder)
      3. Peers, Orderer( /var/hyperledger/production directory/docker volumes)

      기본 환경은 fabric-samples의 test-network를 기준으로 함

      1~3단계는 ./network.sh up 명령어를 사용

      1. 암호화 자료 생성

        cd fabric-samples/test-network
export PATH=${PWD}/../bin:${PWD}:$PATH
# Crypto material in network components
cryptogen generate --config=./organizations/cryptogen/crypto-config-orderer.yaml --output="organizations"
cryptogen generate --config=./organizations/cryptogen/crypto-config-org1.yaml --output="organizations"
cryptogen generate --config=./organizations/cryptogen/crypto-config-org2.yaml --output="organizations"

      2. Consortium Genesis Block 생성

        # system-genesis-block
export FABRIC_CFG_PATH=${PWD}/configtx
# export FABRIC_CFG_PATH=$PWD/../config/
configtxgen -profile TwoOrgsOrdererGenesis -channelID system-channel -outputBlock ./system-genesis-block/genesis.block

      3. Test Network 시작

        IMAGE_TAG=latest docker-compose -f docker/docker-compose-test-net.yaml up -d

      4. Join Peers of Both Organizations to mychannel

        # 채널 생성 step5의 체인코드 항목으로 이동 , 이동전 채널 genesis 블럭 생성의 환경 변수 설정
./network.sh createChannel 
# 채널 아티팩트 생성
mkdir -p channel-artifacts
configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/mychannel.tx -channelID mychannel
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID mychannel -asOrg Org1MSP
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID mychannel -asOrg Org2MSP
# 채널 genesis 블럭 생성
export ORDERER_CA=${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
export PEER0_ORG1_CA=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt

      5. 체인코드 배포(mychannel에 Fabcar)

        # install dependence if not done before
pushd ../chaincode/fabcar/go
GO111MODULE=on go mod vendor
popd
# 체인코드 패키지
CORE_PEER_TLS_ENABLED=true CORE_PEER_LOCALMSPID="Org1MSP" CORE_PEER_TLS_ROOTCERT_FILE=$PEER0_ORG1_CA CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp CORE_PEER_ADDRESS=localhost:7051 peer lifecycle chaincode package fabcar.tar.gz --path ../chaincode/fabcar/go/ --label fabcar_1

      6. Fabcar Chaincode invoke and query

        # init invoke
CORE_PEER_TLS_ENABLED=true CORE_PEER_LOCALMSPID="Org1MSP" CORE_PEER_TLS_ROOTCERT_FILE=$PEER0_ORG1_CA CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp CORE_PEER_ADDRESS=localhost:7051 peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls true --cafile $ORDERER_CA -C mychannel -n fabcar --peerAddresses localhost:7051 --tlsRootCertFiles $PEER0_ORG1_CA --peerAddresses localhost:9051 --tlsRootCertFiles $PEER0_ORG2_CA --isInit -c '{"function":"initLedger","Args":[]}'
# query(org1)
CORE_PEER_TLS_ENABLED=true CORE_PEER_LOCALMSPID="Org1MSP" CORE_PEER_TLS_ROOTCERT_FILE=$PEER0_ORG1_CA CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp CORE_PEER_ADDRESS=localhost:7051 peer chaincode query -C mychannel -n fabcar -c '{"function":"queryAllCars","Args":[]}'
# query(org2)
CORE_PEER_TLS_ENABLED=true CORE_PEER_LOCALMSPID="Org2MSP" CORE_PEER_TLS_ROOTCERT_FILE=$PEER0_ORG2_CA CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp CORE_PEER_ADDRESS=localhost:9051 peer chaincode query -C mychannel -n fabcar -c '{"function":"queryAllCars","Args":[]}'

      7. bloc info 확인
        블록 정보에서 해시 값 및 height 확인

        # org1 
docker exec peer0.org1.example.com peer channel getinfo -c mychannel
## 결과
2020-11-23 05:31:24.419 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
Blockchain info: {"height":7,"currentBlockHash":"H9VY/b/41Be30GLneaXcefek1Bp2CSOPxiBoxqXiRyQ=","previousBlockHash":"f7ePJEGbBrbWe31iAYW7YXIHrJLdTojpdUkNYL0heG0="}
# org2
docker exec peer0.org2.example.com peer channel getinfo -c mychannel
# 결과
2020-11-23 05:33:31.299 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized

      8. back up & restore sh 작성

      vi backup.sh

      set -ev

rm -rf backup
mkdir backup
#Copying Certificates and Configuration files
sleep 5
cp -r organizations backup # crypto-config
cp -r channel-artifacts backup #config

cd backup
mkdir peer
mkdir orderer
cd ..
#Copying Peer and orderer data
sleep 5
docker cp peer0.org1.example.com:/var/hyperledger/production/ backup/peer/
# sudo docker cp peer0.org2.example.com:/var/hyperledger/production/ backup/peer/

docker cp orderer.example.com:/var/hyperledger/production/orderer/ backup/orderer/

#All done
exit 1

      vi restore.sh

      set -ev

COMPOSE_FILE_BASE=docker/docker-compose-test-net.yaml
COMPOSE_FILE_BASE_RESTORE=docker/docker-compose-test-net-restore.yaml

#bringing network down and clearing volumes

docker-compose -f ${COMPOSE_FILE_BASE} down

docker volume prune

docker network prune

#Bringing network Up with Previous Backup
docker-compose -f ${COMPOSE_FILE_BASE_RESTORE}  up -d

#All done...
sleep 20

#querying Data
