Fabric2.2.1从零开始搭建网络(非脚本)

Fabric2.2.1从零开始搭建网络(非脚本)

1. 生成证书

这里使用cryptogen工具来生成证书文件

cryptogen showtemplate > crypto-template.yaml  # 生成一份模板证书配置文件

生成的内容去掉英文注释后大概如下

OrdererOrgs:               # orderer组织的配置
  - Name: Orderer          # 组织名称
    Domain: example.com    # 组织的域名
    EnableNodeOUs: true    # 设置了EnableNodeOUs，会在map下生成config.yaml文件
    Specs:
      - Hostname: orderer  # 生成的证书文件会以{{Hostname}}.{{Domain}}呈现　当前的文件名就是                               
        SANS: 
          - localhost                    # orderer.example.com

PeerOrgs:                  
  - Name: Org1　　　　　　　　　 　　　
    Domain: org1.example.com
    EnableNodeOUs: true
    # template根据count来生成指定份数的证书文件
    # 我的理解是给当前这个组织中的节点生成证书文件　
    # 例如一个组织中有3个节点那么这个count就是3
    Template:
      Count: 1
      SANS: 
        - localhost
      # Start: 5   指定生成的节点从几开始，不指定就从0开始　peer0.org1.example.com
    Users:   # 组织中除了Admin之外还需要生成多少个用户，数量由count决定
      Count: 1

  - Name: Org2
    Domain: org2.example.com
    EnableNodeOUs: true
    Template:
      Count: 1
      SANS: 
        - localhost
    Users:
      Count: 1

根据配置生成证书
注意:这里的SANS一定要填节点真实的地址,不然会导致后面加入通道加入不进去

 cryptogen generate --config=./crypto-template.yaml --output=organizations

2. 生成创世区块

生成创世区块也需要一份配置文件configtx.yaml 我这里直接复制了test-network/configtx/configtx.yaml下面的

Organizations:
    - &OrdererOrg
        Name: OrdererOrg     # 组织名称
        ID: OrdererMSP        # 组织id 用来引用组织   
        MSPDir: organizations/ordererOrganizations/example.com/msp    # 组织的msp文件目录
        Policies:         # 定义组织的一些策略

        AnchorPeers:                       # 定义组织的锚节点

            Capabilities:
                <<: *ApplicationCapabilities

弄好配置文件之后就可以使用configtxgen工具来生成创世区块了

configtxgen -configPath ./ -profile TwoOrgsOrdererGenesis -channelID system-channel -outputBlock ./system-genesis-block/genesis.block

选项	值
profile	在配置文件中配置的Profile
configPath	`configtx.yaml`的文件夹路径`注意这里是文件夹的路径而不是具体的文件的路径`
channeID	`system-channel` 这是fabric的一个默认的通道
outputBlock	要写入创世块的路径,包含文件名

3. 启动网络

    command: peer node start
    ports:
      - 9051:9051
    networks:
      - test

启动网络
这里需要注意CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE需要设置当前docker网络名称默认是当前文件夹名称_test

docker-compose -f {{你的文件名}} up -d

4. 生成通道和锚节点更新交易配置

使用configtxgen 不仅可以生成创建创世区块还可以生成一些交易的配置,他们的关系如下

生成通道交易配置

configtxgen -configPath ./ -profile TwoOrgsChannel -channelID mychannel -outputCreateChannelTx ./channel-artifacts/mychannel.tx

生成两个组织的锚节点更新交易配置

configtxgen -configPath ./ -profile TwoOrgsChannel -channelID mychannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -asOrg Org1
configtxgen -configPath ./ -profile TwoOrgsChannel -channelID mychannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -asOrg Org2
## 这里的 -asOrg 的值是configtx中配置的组织的Name

5. 创建通道加入组织并更新锚节点

先配置组织身份环境变量

export CORE_PEER_LOCALMSPID=Org1MSP
export CORE_PEER_ADDRESS=localhost:7051
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/Admin@org1.example.com/msp
export CORE_PEER_TLS_ENABLED=true

使用我们之前生成的通道交易配置来创建通道证书的路径需要配置绝对路径使用相对路径会读不到

peer channel create -o localhost:7050 -c mychannel --ordererTLSHostnameOverride orderer.example.com -f ./channel-artifacts/mychannel.tx --outputBlock ./channel-artifacts/mychannel.block --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

Org1加入通道并更新锚节点

peer channel join -b ./channel-artifacts/mychannel.block

peer channel update -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com -c mychannel -f ./channel-artifacts/Org1MSPanchors.tx --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

Org2加入通道并更新锚节点

export CORE_PEER_LOCALMSPID=Org2MSP
export CORE_PEER_ADDRESS=localhost:9051
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/Admin@org2.example.com/msp
export CORE_PEER_TLS_ENABLED=true

peer channel join -b ./channel-artifacts/mychannel.block

peer channel update -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com -c mychannel -f ./channel-artifacts/Org2MSPanchors.tx --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

6. 安装链码测试

1. 打包链码这里以fabric的asset-transfer-basic/chaincode-go 为例子

peer lifecycle chaincode package basic.tar.gz --path ./chaincode-go --lang golang --label basic_1

2. Org1和Org2安装链码

export CORE_PEER_LOCALMSPID=Org1MSP
export CORE_PEER_ADDRESS=localhost:7051
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/Admin@org1.example.com/msp
export CORE_PEER_TLS_ENABLED=true

peer lifecycle chaincode install basic.tar.gz

export CORE_PEER_LOCALMSPID=Org2MSP
export CORE_PEER_ADDRESS=localhost:9051
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/Admin@org2.example.com/msp
export CORE_PEER_TLS_ENABLED=true

peer lifecycle chaincode install basic.tar.gz

3. 审议链码定义

先获取链码的package_id

peer lifecycle chaincode queryinstalled

# 这串就是packageid每个人都不一样的
# basic_1:d612c5afb52543307c8d75b79da3de6b3b8d2f984e005a92db9528d0d9176f7d

用Org1和Org2的身份执行下面的命令来审议链码定义 环境变量在上面

peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name basic --version 1.0 --package-id Package ID: {{你的packageId}} --sequence 1 --tls true --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

可以使用checkcommitreadiness来查询链码审议情况通道中大部分的组织同意即可提交

peer lifecycle chaincode checkcommitreadiness --channelID mychannel --name basic --version 1.0 --sequence 1 --tls true --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --output json

4. 提交链码定义

使用一个组织身份提交即可

peer lifecycle chaincode commit -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name basic --version 1.0 --sequence 1 --tls true --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

使用querycommitted可以查询当前通道中提交的链码

peer lifecycle chaincode querycommitted -C mychannel

5. 调用链码

peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls true --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n basic --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 '{"function":"InitLedger","Args":[]}'

查询链码

 peer chaincode query -C mychannel -n basic -c '{"Args":["GetAllAssets"]}'

如果能够查到初始化的数据,那么恭喜你网络搭建成功了!

Fabric2.2.1从零开始搭建网络(非脚本)

Fabric2.2.1从零开始搭建网络(非脚本)

1. 生成证书

2. 生成创世区块

3. 启动网络

4. 生成通道和锚节点更新交易配置

5. 创建通道加入组织并更新锚节点

6. 安装链码测试

1. 打包链码 这里以fabric的asset-transfer-basic/chaincode-go 为例子

2. Org1和Org2安装链码

3. 审议链码定义

4. 提交链码定义

5. 调用链码

1. 打包链码这里以fabric的asset-transfer-basic/chaincode-go 为例子
