Hyperledger Fabric(七)------加入新的Org

开始接下来的步骤之前确保脚本执行没有问题

先启动连个2个Org的： ./byfn.sh up

加入第三个Org： ./eyfn.sh up

如果以上都没问题，最后会输出：

========= All GOOD, EYFN test execution completed ===========

下面就可以开始分步执行了
关于byfn的部分在上一篇博客里已经说的很清楚了，还不清楚的同学可以去看下。

开始之前先清理doker环境：

docker stop $(docker ps -q) 
docker rm $(docker ps -aq)

---

BYFN

先用脚本启动BYFN

./byfn.sh up

准备材料

• 用cryptogen生成需要的证书

  在org3-artifacts目录下，../../bin/cryptogen generate --config=./org3-crypto.yaml

• 生成加入Org3需要的配置文件（JSON格式）

  export FABRIC_CFG_PATH=$PWD && ../../bin/configtxgen -printOrg Org3MSP > ../channel-artifacts/org3.json

• 将orderer的相关证书复制一份到Org3的目录下

  cd ../ && cp -r crypto-config/ordererOrganizations org3-artifacts/crypto-config/

更新Channel

• 进入CLI：docker exec -it cli bash

  导入环境变量（orderer的tls证书和channel名字）：export ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem && export CHANNEL_NAME=mychannel

• 接下来就是一系列pb文件和json文件的转换,比较繁琐,建议直接去看官方文档,我这里画了个转换的流程图作为参考.

  

  到这一步我们应该得到了最终需要的文件org3_update_in_envelope.pb

• 对这个文件进行签名,根据policy先前的两个Org都要签名.

  peer0.Org1签名:peer channel signconfigtx -f org3_update_in_envelope.pb

  peer0.org2签名:

  环境变量:

  export CORE_PEER_LOCALMSPID="Org2MSP"
  export 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
  export CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/[email protected].example.com/msp
  export CORE_PEER_ADDRESS=peer0.org2.example.com:7051

  签名peer channel signconfigtx -f org3_update_in_envelope.pb

• 更新channel

  peer channel update -f org3_update_in_envelope.pb -c $CHANNEL_NAME -o orderer.example.com:7050 --tls --cafile $ORDERER_CA

  如果成功则会输出：Successfully submitted channel update

文档中提到的leading peer选举我们配置文件里定义了动态选举.

CORE_PEER_GOSSIP_USELEADERELECTION=true
CORE_PEER_GOSSIP_ORGLEADER=false

加入网络

• 启动Org3相关的容器：docker-compose -f docker-compose-org3.yaml up -d

• 进入Org3CLI:docker exec -it Org3cli bash

• 导入orderer的tls证书路径和channel名:export ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem && export CHANNEL_NAME=mychannel

• 用peer channel fetch取得genesis block

  peer channel fetch 0 mychannel.block -o orderer.example.com:7050 -c $CHANNEL_NAME --tls --cafile $ORDERER_CA

• 将peer0.Org3加入网络：peer channel join -b mychannel.block

• 将peer1.Org3加入网络:

  export CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org3.example.com/peers/peer1.org3.example.com/tls/ca.crt && export CORE_PEER_ADDRESS=peer1.org3.example.com:7051
  peer channel join -b mychannel.block

• install chaincode(这里安装在了peer1.Org3上):
  peer chaincode install -n mycc -v 2.0 -p github.com/chaincode/chaincode_example02/go/

• 打开新的终端进入CLI：docker exec -it cli bash

  export CORE_PEER_LOCALMSPID="Org1MSP"
  export 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
  export CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected].example.com/msp
  export CORE_PEER_ADDRESS=peer0.org1.example.com:7051

  这时是peer0.Org1身份

  install chaincode：peer chaincode install -n mycc -v 2.0 -p github.com/chaincode/chaincode_example02/go/

  CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/[email protected].example.com/msp
  CORE_PEER_ADDRESS=peer0.org2.example.com:7051
  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

  这时是peer0.Org2身份

  install chaincode：peer chaincode install -n mycc -v 2.0 -p github.com/chaincode/chaincode_example02/go/

• 更新chaincode了

  peer chaincode upgrade -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA -C $CHANNEL_NAME -n mycc -v 2.0 -c '{"Args":["init","a","90","b","210"]}' -P "OR ('Org1MSP.peer','Org2MSP.peer','Org3MSP.peer')"

  这里指定了新的共识策略-P "OR ('Org1MSP.peer','Org2MSP.peer','Org3MSP.peer')"

• 接下来就可以转账查询了

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

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