创建第一个fabric网络

• Generate Network Artifacts

  cd first-network

  先关闭服务

  ./byfn.sh -m down

  然后创建

  ./byfn.sh -m generate

• 创建创世区块

  ../bin/cryptogen generate --config=./crypto-config.yaml

  该文件是first-network下面的配置文件

• 生成初始区块

  export FABRIC_CFG_PATH=$PWD

  f

  ../bin/configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

• 生成应用通道的配置信息

  export CHANNEL_NAME=mychannel

  链的一个标识

  ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME

• 生成锚节点配置更新文件

../bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP

../bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP

锚节点用于和对等节点进行通信

• 操作网络

编辑 docker-compose-cli.yaml 注释掉command命令

路径:/goWorkPlace/src/github.com/hyperledger/fabric/peer

CHANNEL_NAME=$CHANNEL_NAME TIMEOUT=600 docker-compose -f docker-compose-cli.yaml up -d

• 进入docker容器

  docker exec -it cli bash

• 创建通道

export CHANNEL_NAME=mychannel

• 创建区块链

peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

• 加入通道

  peer channel join -b mychannel.block

• 安装链码

  peer chaincode install -n mycc -v 1.4 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02

用以上代码安装,会被认为是本地路径,查看本地挂载位置docker-compser-cli.yaml

故本文使用以下代码

peer chaincode install -n mycc -v 1.4 -p github.com/chaincode/chaincode_example02/go

• 实例化链码

  peer chaincode instantiate -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --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 -v 1.4 -c '{"Args":["init","a","100","b","200"]}' -P "OR ('Org1MSP.member','Org2MSP.member')"

初始化a,b两个节点,a有一百块,b有两百块

• 查询

peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}'

• 转账

  peer chaincode invoke -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --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 -c '{"Args":["invoke","a","b","10"]}'

以上为一次基本流程
