构建你的第一个网络--fabric--release-1.4
一、自动构建
1.生成网络构件（进入 first-network 目录下）
./byfn.sh generate
第一步为我们的各种网络实体生成证书和秘钥。创世区块 genesis block用于引导排序服务，也包含了一组配置 Channel 所需要的配置交易集合。
2.启动网络
./byfn.sh up
这一步会启动所有的容器，然后启动一个完整的 end-to-end 应用场景。完成后，它应该在您的终端窗口中显示以下内容:
Query Result: 90 2017-05-16 17:08:15.158 UTC [main] main -> INFO 008 Exiting..... ===================== Query successful on peer1.org2 on channel 'mychannel' ===================== ===================== All GOOD, BYFN execution completed ===================== _____ _ _ ____ | ____| | \ | | | _ \ | _| | \| | | | | | | |___ | |\ | | |_| | |_____| |_| \_| |____/
3.关闭网络
./byfn.sh down
这一步会结束掉你所有的容器，移除加密的材料和四个构件，并且从 Docker 仓库删除链码镜像。
二、手动构建
1.手动生成构件
为组织生成证书
cryptogen generate --config=./crypto-config.yaml
终端将会输出
org1.example.com
org2.example.com
告诉 configtxgen 工具去哪儿寻找它需要的 configtx.yaml 文件
export FABRIC_CFG_PATH=$PWD
创建排序通道创世区块
configtxgen -profile TwoOrgsOrdererGenesis -channelID byfn-sys-channel -outputBlock ./channel-artifacts/genesis.block
并出现下列类似输出
2020-07-05 10:37:52.167 CST [common.tools.configtxgen.localconfig] LoadTopLevel -> INFO 005 Loaded configuration: /root/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network/configtx.yaml 2020-07-05 10:37:52.169 CST [common.tools.configtxgen] doOutputBlock -> INFO 006 Generating genesis block 2020-07-05 10:37:52.170 CST [common.tools.configtxgen] doOutputBlock -> INFO 007 Writing genesis block
2.创建通道配置交易
export CHANNEL_NAME=mychannel
configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME
为构建的通道上的组织 Org1 、Org2 定义锚节点
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP
3.启动网络
启动容器
# 可以使用命令 sudo docker ps 查看容器是否启动成功
docker-compose -f docker-compose-cli.yaml up -d
进入cli容器
docker exec -it cli bash
如果成功则会发现
root@0d78bb69300d:/opt/gopath/src/github.com/hyperledger/fabric/peer#
4.创建和加入通道
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 --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
把 peer0.org1.example.com 加入通道
peer channel join -b mychannel.block
注意：如果你想向其他 Peer 节点或者排序节点发送调用，那么你发送任何 CLI 调用的时候都需要像下边的命令一样覆盖这些环境变量（当前节点是peer0，因此无需更改）
# Environment variables for PEER0
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
把 peer0.org2.example.com 加入通道
# 配置环境变量
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
#加入通道
peer channel join -b mychannel.block
5.更新锚节点
# 配置环境 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 # 将 Org1 的锚节点定义为 peer0.org1.example.com 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 # 配置环境 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 # 将 Org2 的锚节点定义为 peer0.org2.example.com peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org2MSPanchors.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
6.安装和实例化链码
- 链码的实例化只需要一次
- 链码的安装针对每个背书节点，都需要安装一次。
在 Org1 的 peer0 节点上安装 Go 链码（如果安装出现问题请配置环境后再次尝试）
peer chaincode install -n mycc -v 1.0 -p github.com/chaincode/chaincode_example02/go/
在 Org2 的 peer0 节点上也安装链码
# Environment variables for PEER0 in Org2 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 chaincode install -n mycc -v 1.0 -p github.com/chaincode/chaincode_example02/go/
实例化链码
peer chaincode instantiate -o orderer.example.com:7050 --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 -C $CHANNEL_NAME -n mycc -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}' -P "AND ('Org1MSP.peer','Org2MSP.peer')"
7.查询与调用
查询 a 的值，以确保链码被正确实例化并且向状态数据库写入了数据
peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}'
调用，从 a 账户向 b 账户转账 10
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","a","b","10"]}'
再次查询
peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}'
由于 a 的初始值为 100 ，你会发现
Query Result: 90
8.后续可以继续为其他节点安装链码
在 Org2 的 peer1 节点上安装链码
# Environment variables for PEER1 in Org2 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 chaincode install -n mycc -v 1.0 -p github.com/chaincode/chaincode_example02/go/
查询
# Org2 的 peer1 需要先加入通道才可以响应查询
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 peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}'
结果
Query Result: 90
