创建自己的fabric网络

前提是已经安装好fabric的相关环境

安装相关网络环境请看另一篇

文件简介并需要提前准备的

1. crypto-config.yaml: 密钥配置文件
   ·order节点配置：个数、名称等
   ·peer节点配置：个数、名称等

2. configtx.yaml: 组织、通道配置文件
   ·联盟配置：系统链（全局组织信息）；业务链
   ·组织链配置：
   ·order组织配置：solo（共识类型、出块时间间隔、块大小）Kafka

3. docker-compose: docker镜像配置，如order节点、peer节点的配置

创建命令流程

1. 清除环境

docker rm $(docker ps -aq)
systemctl restart docker

2. 设置路径

export FABRIC_CFG_PATH=$GOPATH/src/github.com/hyperledger/my-network

3. 编译生成cryptogen

cd ~/go/src/github.com/hyperledger/fabric
make cryptogen

4. 编辑crypto-config.yaml，生成证书

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

5. 编译生成configtxgen

make configtxgen

6. 编辑configtx.yaml

6.1 生成创世区块

configtxgen -profile OneOrgOrdererGenesis -outputBlock ./config/genesis.block

6.2 生成通道

configtxgen -profile TwoOrgChannel -outputCreateChannelTx ./config/kuanchannel.tx -channelID kuanchannel

6.3 锚节点配置

configtxgen -profile TwoOrgChannel -outputAnchorPeersUpdate ./config/Org0MSPanchors.tx -channelID kuanchannel -asOrg Org0MSP
configtxgen -profile TwoOrgChannel -outputAnchorPeersUpdate ./config/Org1MSPanchors.tx -channelID kuanchannel -asOrg Org1MSP

7. 编辑docker-compose，启动网络

docker-compose up -d

8. 创建通道

peer channel create -o orderer.kuan.com:7050 -c kuanchannel -f /etc/hyperledger/config/kuanchannel.tx

9. 加入通道

peer channel join -b kuanchannel.block 
其他节点加入通道需要将kuanchannel.block复制到其他通道再执行该命令

10. 创建锚节点

peer channel update -o orderer.kuan.com:7050 -c kuanchannel -f /etc/hyperledger/config/Org1MSPanchors.tx

11. 安装链码(java或者node链码需要额外添加一个参数 -l java 或者-l node )

peer chaincode install -n cc_sample -v 1.0 -p ChainCode/cmd

12. 初始化链码(java或者node链码需要额外添加一个参数 -l java 或者-l node )

peer chaincode instantiate -o orderer.kuan.com:7050  -C kuanchannel -n cc_sample -v 1.0 -c '{"Args":["init"]}'  --tls false --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

13. 更新链码

peer chaincode upgrade -o orderer.kuan.com:7050  -C kuanchannel -n cc_sample -v 1.0 -c '{"Args":["init"]}'  --tls false --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

14. 调用链码

peer chaincode invoke -o orderer.kuan.com:7050 -C kuanchannel -n cc_filebackup -c '{"Args":["newFile","12","a","111","1","sad,sa","asd","123213","http://noname.com","2018-06-06","132"]}' --tls false --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
