Hyperledger Fabric Samples 建立第一个

Generate Network Artifacts

$ cd fabric-samples/first-network
$ ./byfn.sh -m generate

运行结果：

生成初始区块

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

$ export FABRIC_CFG_PATH=$PWD
$ ../bin/configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

生成应用通道的配置信息

$ export CHANNEL_NAME=mychannel

$ ../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

操作网络

编辑 docker-compose-cli.yaml，注释到 command 命令

working_dir: /opt/gopath/src/github.com/hyperledger/fabric/peer
#command: /bin/bash -c './scripts/script.sh ${CHANNEL_NAME}; sleep $TIMEOUT'
volumes

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

创建和加入通道

进入docker容器

$ docker exec -it cli bash

创建通道

$ export CHANNEL_NAME=mychannel

$ 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

链上代码 （链码）

安装链码

$ peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02

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 1.0 -c '{"Args":["init","a", "100", "b","200"]}' -P "OR ('Org1MSP.member','Org2MSP.member')"

查询

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

查询结果：

Query Result: 100

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"]}'

查询a账户的金额:

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

## 结果
Query Result: 90

问题记录

docker 运行时出错，可以查询docker正在运行的容器，删除运行的容器

# 查询正在运行的容器
docker ps -a

# 删除运行的容器
docker rm -f $(docker ps -aq)

清理网络

./byfn.sh -m down
