hyperledger-fabric 如何在现有的区块链联盟中加入新的企业机构

本案例依然基于First Network示例进行操作演示，Fisrt Network示例中已经存在org1、org2，现操作演示加入org3。

1.快速启动Fisrt Network

[root@huangzhenhua first-network]# cd /opt/gopath/src/github.com/hyperledger/fabric-samples/first-network

[root@huangzhenhua first-network]# ./byfn.sh up

2.为org3生成通讯密钥

[root@huangzhenhua first-network]# ls

base     channel-artifacts  crypto-config       docker-compose-cli.yaml         docker-compose-couch.yaml         docker-compose-e2e.yaml   eyfn.sh         README.md

byfn.sh  configtx.yaml      crypto-config.yaml  docker-compose-couch-org3.yaml  docker-compose-e2e-template.yaml  docker-compose-org3.yaml  org3-artifacts  scripts

[root@huangzhenhua first-network]# cd org3-artifacts/

[root@huangzhenhua org3-artifacts]# ls

configtx.yaml  org3-crypto.yaml

[root@huangzhenhua org3-artifacts]# ../../bin/cryptogen generate --config=./org3-crypto.yaml

org3.example.com

3.使用configtxgen工具将密钥导出到一个json文件中

[root@huangzhenhua org3-artifacts]# export FABRIC_CFG_PATH=$PWD && ../../bin/configtxgen -printOrg Org3MSP > ../channel-artifacts/org3.json

2018-03-30 15:50:57.522 CST [common/tools/configtxgen] main -> INFO 001 Loading configuration

2018-03-30 15:50:57.569 CST [msp] getMspConfig -> INFO 002 Loading NodeOUs

4.复制共识服务节点密钥到org3密钥存放目录

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

5.配置CLI docker容器环境

5.1.进入CLI容器

[root@huangzhenhua first-network]# docker exec -it cli bash

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# 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

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# echo $ORDERER_CA && echo $CHANNEL_NAME

/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

mychannel

5.2.在CLI容器安装jq工具

root@9e2f31f76519:/opt/gopath/src/github.com/hyperledger/fabric/peer# apt update && apt install -y jq

6.生成相应配置文件

6.1.获取orderer的block配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer channel fetch config config_block.pb -o orderer.example.com:7050 -c $CHANNEL_NAME --tls --cafile $ORDERER_CA

查看是否生成config_block.pb配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# ls

channel-artifacts  config_block.pb  crypto  log.txt  mychannel.block  scripts

6.2.通过configtxlator工具将config_block.pb配置文件转换为json配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# configtxlator proto_decode --input config_block.pb --type common.Block | jq .data.data[0].payload.data.config > config.json

查看是否生成config.json配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# ls

channel-artifacts  config.json  config_block.pb  crypto  log.txt  mychannel.block  scripts

6.3.使用jq工具在org3.json配置文件中添加部分信息，并重新生成modified_config.json配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# jq -s '.[0] * {"channel_group":{"groups":{"Application":{"groups": {"Org3MSP":.[1]}}}}}' config.json ./channel-artifacts/org3.json > modified_config.json

查看是否生成modified_config.json配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# ls

channel-artifacts  config.json  config_block.pb  crypto  log.txt  modified_config.json  mychannel.block  scripts

6.4.通过configtxlator工具将config.json配置文件转换为config.pb配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# configtxlator proto_encode --input config.json --type common.Config --output config.pb

查看是否生成config.pb配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# ls

channel-artifacts  config.json  config.pb  config_block.pb  crypto  log.txt  modified_config.json  mychannel.block  scripts

6.5.通过configtxlator工具将modified_config.json配置文件转换为modified_config.pb配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# configtxlator proto_encode --input modified_config.json --type common.Config --output modified_config.pb

查看是否生成config.pb配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# ls

channel-artifacts  config.json  config.pb  config_block.pb  crypto  log.txt  modified_config.json  modified_config.pb  mychannel.block  scripts

6.6.通过configtxlator工具计算config.pb、modified_config.pb配置增量变化，并生成org3_update.pb文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# configtxlator compute_update --channel_id $CHANNEL_NAME --original config.pb --updated modified_config.pb --output org3_update.pb

查看是否生成org3_update.pb配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# ls

channel-artifacts  config.json  config.pb  config_block.pb  crypto  log.txt  modified_config.json  modified_config.pb  mychannel.block  org3_update.pb  scripts

6.7.通过configtxlator工具将org3_update.pb配置文件转换为org3_update.json配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# configtxlator proto_decode --input org3_update.pb --type common.ConfigUpdate | jq . > org3_update.json

查看是否生成org3_update.json配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# ls

channel-artifacts  config.pb        crypto   modified_config.json  mychannel.block   org3_update.pb

config.json        config_block.pb  log.txt  modified_config.pb    org3_update.json  scripts

6.8.在org3_update.json中添加部分信息，并生成新的配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# echo '{"payload":{"header":{"channel_header":{"channel_id":"mychannel", "type":2}},"data":{"config_update":'$(cat org3_update.json)'}}}' | jq . > org3_update_in_envelope.json

查看是否生成org3_update_in_envelope.json配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# ls

channel-artifacts  config.pb        crypto   modified_config.json  mychannel.block   org3_update.pb                scripts

config.json        config_block.pb  log.txt  modified_config.pb    org3_update.json  org3_update_in_envelope.json

6.9.通过configtxlator工具将org3_update_in_envelope.json配置文件转换为org3_update_in_envelope.pb配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# configtxlator proto_encode --input org3_update_in_envelope.json --type common.Envelope --output org3_update_in_envelope.pb

查看是否生成org3_update_in_envelope.pb配置文件

root@d995c5e2873d:/opt/gopath/src/github.com/hyperledger/fabric/peer# ls

channel-artifacts  config.pb        crypto   modified_config.json  mychannel.block   org3_update.pb                org3_update_in_envelope.pb

config.json        config_block.pb  log.txt  modified_config.pb    org3_update.json  org3_update_in_envelope.json  scripts

7.更新org1和org2的配置信息
