First Network 详细分析

生成 fabric 证书和配置等文件

./byfn.sh generate

日志分析并手动构建细节

  • 1. 以获取生成将用于crypto-config.yaml文件中定义的网络配置的证书,对应手工配置:

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

    对应输出日志:

    org1.example.com
    org2.example.com

    证书和密钥(即MSP材料)将输出到 first-network 目录中的 crypto-config 文件夹。

  • 2. configtxgen 工具在哪里查找配置文件 configtx.yaml 并调用 configtxgen 工具来创建 orderer 创世区块,对应手工配置:

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

    对应输出类似日志:

    2018-08-23 10:36:13.825 CST [common/tools/configtxgen] main -> WARN 001 Omitting the channel ID for configtxgen is deprecated.  Explicitly passing the channel ID will be required in the future, defaulting to 'testchainid'.

    创世区块 genesis.block 将输出到 first-network 目录中的 channel-artifacts 文件夹。

  • 3. 创建通道配置文件,对应手工配置:

    export CHANNEL_NAME=mychannel  && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME

    对应输出类似日志:

    通道上为Org2定义锚对等节点配置文件 Org2MSPanchors.tx 将输出到 first-network 目录中的 channel-artifacts 文件夹。

网络启动

./byfn.sh up

 日志分析可以分为两部分并手动构建细节

  • 第一日志部分

    Creating network "net_byfn" with the default driver
    Creating volume "net_orderer.example.com" with default driver
    Creating volume "net_peer0.org1.example.com" with default driver
    Creating volume "net_peer1.org1.example.com" with default driver
    Creating volume "net_peer0.org2.example.com" with default driver
    Creating volume "net_peer1.org2.example.com" with default driver
    Creating peer0.org2.example.com ... done
    Creating orderer.example.com    ... done

    Creating peer1.org2.example.com ... done
    Creating peer0.org1.example.com ... done
    Creating cli                    ... done

    这部分其实是利用 docker-compose 启动容器编排,具体命令为:

    docker-compose -f docker-compose-cli.yaml up -d

    这部分其实是利用 docker exec 命令 进入 cli 容器中执行 scripts/script.sh 脚本,其参数为 mychannel 3 golang 10 false,具体命令为:

    docker exec cli scripts/script.sh mychannel 3 golang 10 false

         第二部分日志具体分析

    • 首先进入 cli 容器:

      docker exec -it cli bash

    • 接下来在容器里操作,配置环境变量:

      export CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
      export CORE_PEER_ADDRESS=peer0.org1.example.com:7051
      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

    • 创建 mychannel 通道(相当于通过创世区块创建区块链,每个通道相当于每条独立的区块链):

      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

      输出日志:

      2018-08-23 06:56:14.257 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
      2018-08-23 06:56:14.273 UTC [cli/common] readBlock -> INFO 002 Got status: &{NOT_FOUND}
      2018-08-23 06:56:14.274 UTC [channelCmd] InitCmdFactory -> INFO 003 Endorser and orderer connections initialized
      2018-08-23 06:56:14.480 UTC [cli/common] readBlock -> INFO 004 Received block: 0

    • 节点加入 mychannel 通道(相当于节点加入区块链网络): 加入通道需要用到环境变量的值,默认为 peer0.org1 节点加入通道。

      peer channel join -b mychannel.block

      输出日志:

      2018-08-23 07:10:09.620 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized

      要其他节点也加入 mychannel 通道,需要修改环境变量的值,也很简单,举个例子,如果 peer1.org2 节点加入通道,只要把所有环境变量值出现 org1 替换成 org2 ,并把 CORE_PEER_ADDRESS值中的 peer0替换成 peer1 ,如下:

      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: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

      修改后继续执行:peer channel join -b mychannel.block,同理完成 peer0.org2,peer1.org1,peer1.org2 加入 mychannel 通道。

    • 更新通道的锚节点,实质上是在通道的创世块之上添加了额外的配置信息(所谓锚节点就是某联盟在通道中公开链接的一个或多个节点) 更新通道中 Org1 组织的锚节点为 peer0.org1.example.com: 首先确保环境变量是 peer0.org1 的信息:

      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

      然后更新

      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

      更新通道中 Org2 组织的锚节点为 peer0.org2.example.com: 首先确保环境变量是 peer0.org2 的信息:

      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: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

      然后更新

      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

    • 安装和实例化Chaincode 安装 golang版 Chaincode ,安装到的节点为环境变量的配置节点:

      peer chaincode install -n mycc -v 1.0 -p github.com/chaincode/chaincode_example02/go/

      日志输出:

      2018-08-23 11:25:20.439 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
      2018-08-23 11:25:20.439 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc
      2018-08-23 11:25:20.831 UTC [chaincodeCmd] install -> INFO 003 Installed remotely response:

      接下来,在通道上实例化链码。这将初始化通道上的链代码,设置链代码的认可策略,并为目标节点启动链代码容器:

      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')"

      日志输出:

      2018-08-23 11:31:33.050 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
      2018-08-23 11:31:33.050 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc

    • 查询以确保链代码已正确实例化并填充状态数据库:

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

      日志输出:

      100

    • 调用,a取10给b

      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:7051 --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"]}'

      输出

      INFO 001 Chaincode invoke successful. result: status:200

      查询结果得到: a:90,b:210,成功结束 !!!
