设置debug模式 修改docker-compose-cli.yaml
1 2 3 4 5 6 7 8 9 10 cli: container_name: cli image: hyperledger/fabric-tools:$IMAGE_TAG tty: true stdin_open: true environment: - GOPATH=/opt/gopath - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock - FABRIC_LOGGING_SPEC=DEBUG #- FABRIC_LOGGING_SPEC=INFO
生成msp证书 此时默认当前目录下crypto-config.yaml已经配置好
1 cryptogen generate --config=./crypto-config.yaml
生成排序服务创世区块 1 2 export FABRIC_CFG_PATH=$PWD configtxgen -profile SampleMultiNodeEtcdRaft -channelID byfn-sys-channel -outputBlock ./channel-artifacts/genesis.block
生成通道配置创世区块 1 export CHANNEL_NAME=mychannel && configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME
定义组织锚节点 org1
1 2 export CHANNEL_NAME=mychannel configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP
org2
1 configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP
启动网络 1 docker-compose -f docker-compose-cli.yaml -f docker-compose-etcdraft2.yaml up -d
创建并加入频道 1 docker exec -it cli bash

加入频道 1 peer channel join -b mychannel.block
设置环境变量加入其他节点 1 CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp CORE_PEER_ADDRESS=peer0.org2.example.com:9051 CORE_PEER_LOCALMSPID="Org2MSP" CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt peer channel join -b mychannel.block
更新锚点1 1 peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org1MSPanchors.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

安装链码 1 2 3 4 5 6 7 8 9 cd /opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode/abstore/go GO111MODULE=on go mod vendor cd - # this packages a Go chaincode. # make note of the --lang flag to indicate "golang" chaincode # for Go chaincode --path takes the relative path from $GOPATH/src # The --label flag is used to create the package label peer lifecycle chaincode package mycc.tar.gz --path github.com/hyperledger/fabric-samples/chaincode/abstore/go/ --lang golang --label mycc_1
以下命令以将软件包安装在Org1的peer0上 1 peer lifecycle chaincode install mycc.tar.gz
查询对等方 1 peer lifecycle chaincode queryinstalled
保存ID为环境变量(上面查询到的) 1 CC_PACKAGE_ID=mycc_1:f5cc6d6e871262e8da9788f3d463442e51c482ec8288c13e4545741ad45d86fa
修改环境变量在org2上安装 1 2 3 4 CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp CORE_PEER_ADDRESS=peer0.org2.example.com:9051 CORE_PEER_LOCALMSPID="Org2MSP" CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
安装链码 1 peer lifecycle chaincode install mycc.tar.gz
批准mycc在org2上链码 1 2 export CHANNEL_NAME=mychannel peer lifecycle chaincode approveformyorg --channelID $CHANNEL_NAME --name mycc --version 1.0 --init-required --package-id $CC_PACKAGE_ID --sequence 1 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
切换环境变量到org1，在org1上批准 1 2 3 4 5 6 CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp CORE_PEER_ADDRESS=peer0.org1.example.com:7051 CORE_PEER_LOCALMSPID="Org1MSP" CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt peer lifecycle chaincode approveformyorg --channelID $CHANNEL_NAME --name mycc --version 1.0 --init-required --package-id $CC_PACKAGE_ID --sequence 1 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
查看是否批准 1 peer lifecycle chaincode checkcommitreadiness --channelID $CHANNEL_NAME --name mycc --version 1.0 --init-required --sequence 1 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --output json
使用命令提交给渠道 1 peer lifecycle chaincode commit -o orderer.example.com:7050 --channelID $CHANNEL_NAME --name mycc --version 1.0 --sequence 1 --init-required --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
调用链码进行交互（设置值并初始化） 1 peer chaincode invoke -o orderer.example.com:7050 --isInit --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["Init","donor","100","recipient","100"]}' --waitForEvent
查询
1 peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","donor"]}'
转账：将10从a移动到b，并更新数据库
1 peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["invoke","donor","recipient","10"]}' --waitForEvent
查询
1 peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","donor"]}'
此时会显示90，查询正确，转账成功
设置环境变量并在其他对等节点安装链码 1 2 3 4 5 6 CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp CORE_PEER_ADDRESS=peer1.org2.example.com:10051 CORE_PEER_LOCALMSPID="Org2MSP" CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer1.org2.example.com/tls/ca.crt peer lifecycle chaincode install mycc.tar.gz
将这个节点加入通道 1 CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp CORE_PEER_ADDRESS=peer1.org2.example.com:10051 CORE_PEER_LOCALMSPID="Org2MSP" CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer1.org2.example.com/tls/ca.crt peer channel join -b mychannel.block
在这个节点上进行交互 1 peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","donor"]}'
这里查询到的数据应该和之前在另一个节点上查询的相同
