使用最新的github上fabric-samples/master项目

测试网络说明

  • solo共识模式：1 orderer， 2 orgs [ 1 peer / org]

参考文档

默认版本：deployCC是装的asset合约

一、使用fabric源码编译相关的工具

  1. 下载源码
$ cd $GOPATH/src/github.com/hyperledger
$ git clone https://github.com/hyperledger/fabric.git
$ git checkout release-2.2

$ git clone https://github.com/hyperledger/fabric-samples.git
  1. 修改Docker的镜像

参考：Docker和alpine镜像内国内源配置

  1. 编译相关工具
$ cd $GOPATH/src/github.com/hyperledger/fabric
$ make checks
$ make configtxgen cryptogen orderer peer docker
  1. 拷贝其他环境
$ cd $GOPATH/src/github.com/hyperledger/fabric
$ mkdir ../fabric-samples/bin 
$ mkdir ../fabric-samples/config 
$ cp build/bin/* ../fabric-samples/bin
$ cp sampleconfig/* ../fabric-samples/config

$ export PATH=PATH:$GOPATH/src/github.com/hyperledger/fabric-samples/bin

二、network.sh 使用说明

$ ./network.sh -h
Usage:
  network.sh <Mode> [Flags]
    <Mode>
      - 'up' - bring up fabric orderer and peer nodes. No channel is created
      - 'up createChannel' - bring up fabric network with one channel
      - 'createChannel' - create and join a channel after the network is created
      - 'deployCC' - deploy the fabcar chaincode on the channel
      - 'down' - clear the network with docker-compose down
      - 'restart' - restart the network

    Flags:
    -ca <use CAs> -  create Certificate Authorities to generate the crypto material
    -c <channel name> - channel name to use (defaults to "mychannel")
    -s <dbtype> - the database backend to use: goleveldb (default) or couchdb
    -r <max retry> - CLI times out after certain number of attempts (defaults to 5)
    -d <delay> - delay duration in seconds (defaults to 3)
    -l <language> - the programming language of the chaincode to deploy: go (default), javascript, or java
    -v <version>  - chaincode version. Must be a round number, 1, 2, 3, etc
    -i <imagetag> - the tag to be used to launch the network (defaults to "latest")
    -verbose - verbose mode
  network.sh -h (print this message)

 Possible Mode and flags
  network.sh up -ca -c -r -d -s -i -verbose
  network.sh up createChannel -ca -c -r -d -s -i -verbose
  network.sh createChannel -c -r -d -verbose
  network.sh deployCC -l -v -r -d -verbose

 Taking all defaults:
    network.sh up

 Examples:
  network.sh up createChannel -ca -c mychannel -s couchdb -i 2.0.0
  network.sh createChannel -c channelName
  network.sh deployCC -l javascript

三、启动测试网络

./network.sh up

  • 只启动节点，没有通道
  • 目前启动的网络是solo模式（1个orderer、2个peer）
  • ./network.sh up createChannel mychannel启动网络时同时启动mychannel

创建channel

  • ./network.sh createChannel
  • 启动了mychannel
  • ./network.sh createChannel -c channel1 指定channel的名称，通道名称只能小写

./network.sh createChannel -c newchannel的具体过程（链码生命周期管理过程）如下：

verayy@verayy-VirtualBox:~/codes/go/src/github.com/hyperledger/fabric-samples/test-network$ ./network.sh createChannel -c newchannel

If network is not up, starting nodes with CLI timeout of '5' tries and CLI delay of '3' seconds and using database 'leveldb

Chaincode initialization is not required

四、Interacting with the network

1. 设置变量

Make sure that you are operating from the test-network directory

export PATH=${PWD}/../bin:${PWD}:$PATH
export FABRIC_CFG_PATH=$PWD/../config/

# 下面Org1和Org2选择一个配置即可

# Environment variables for Org1
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/[email protected]/msp
export CORE_PEER_ADDRESS=localhost:7051

# Environment variables for Org2
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/[email protected]/msp
export CORE_PEER_ADDRESS=localhost:9051

2. 查询fabcar链码

$ peer chaincode query -C mychannel -n fabcar -c '{"Args":["QueryAllCars"]}'

3. 调用fabcar链码

peer chaincode invoke \
-o localhost:7050 \
--ordererTLSHostnameOverride orderer.example.com \
--tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem \
--peerAddresses localhost:7051 \
--tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt \
--peerAddresses localhost:9051 \
--tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt \
-C mychannel \
-n fabcar \
-c '{"function":"InitLedger","Args":[]}'

4. 创建新的通道

// 生成通道配置文件
$ configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/testchannel.tx -channelID testchannel  -configPath ./configtx/

// 生成org1的锚节点配置文件
$ configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID testchannel -asOrg Org1MSP -configPath ./configtx/

// 生成org2的锚节点配置文件
$ configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID testchannel -asOrg Org2MSP -configPath ./configtx/

// 创建通道
$ peer channel create -o localhost:7050 -c testchannel --ordererTLSHostnameOverride orderer.example.com \
-f ./channel-artifacts/testchannel.tx \
--outputBlock ./channel-artifacts/testchannel.block \
--tls --cafile /home/verayy/codes/go/src/github.com/hyperledger/fabric-samples/test-network/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

// 每个org加入通道，需要切换上述的配置文件
$ peer channel join -b ./channel-artifacts/testchannel.block

// 使用每个org的管理员身份更新锚节点配置
$ peer channel update -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com -c testchannel -f ./channel-artifacts/Org1MSPanchors.tx --tls --cafile /home/verayy/codes/go/src/github.com/hyperledger/fabric-samples/test-network/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
