Fabric实战（2）运行一个简单的fabric网络（容器外）

本文章所有操作基于的操作系统版本是：ubuntu16.04 64位

上一节中我们成功安装Fabric之后，就可以启动相关模块开始工作了，但是Fabric的配置和启动过程比较繁琐，在后续文章中会介绍详细的模块使用方法，在这之前我们先搭建一个简单的Fabric网络，这个网络虽然简单，但是包含了fabric的核心组成部分。

docker容器可以很方便的部署fabric节点，但是却不能很容易的调式fabric的源代码，如果要深入学习fabric源码，可能要经常进行fabric 源码调式，所以我们在容器外来搭建这个简单的fabric网络。

首先创建一个目录，并切换到该目录下，这个简单的网路所有配置文件放到这个目录下：

 mkdir -p ~/fabric-ws/simple-demo/

 cd ~/fabric-ws/simple-demo

1.生成证书文件

创建一个名为crypto-config.yaml的配置文件，内容如下：

OrdererOrgs:
  - Name: Orderer
    Domain: simple-network.com
    Specs:
      - Hostname: orderer

PeerOrgs:
  - Name: Org1
    Domain: org1.simple-network.com
    Template:
      Count: 2
    Users:
      Count: 2

  - Name: Org2
    Domain: org2.simple-network.com
    Template:
      Count: 2
    Users:
      Count: 2

生成证书

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

修改端口映射文件：

sudo vi /etc/host

追加如下内容：

127.0.0.1 orderer.simple-network.com
127.0.0.1 peer0.org1.simple-network.com
127.0.0.1 peer1.org1.simple-network.com
127.0.0.1 peer0.org2.simple-network.com
127.0.0.1 peer1.org2.simple-network.com

注意 ：hosts文件中的127.0.0.1是本机IP，如果是多台机器部署请根据各个机器的IP指定，不要照抄。

测试是否能ping通

ping orderer.simple-network.com

2.生成创世块、通道和锚点文件

首先创建一个order目录，来存放order的相关配置

mkdir -p ~/fabric-ws/simple-demo/order

cd ~/fabric-ws/simple-demo/order

在order目录中创建一个名为configtx.yaml的配置文件，内容如下：

Profiles: 
    TestTwoOrgsOrdererGenesis:
        Orderer:
            <<: *OrdererDefaults
            Organizations:
                    - *OrdererOrg
        Consortiums:
            SampleConsortium:
                Organizations:
                        - *Org1
                        - *Org2

    TestTwoOrgsChannel:
        Consortium: SampleConsortium
        Application:
                <<: *ApplicationDefaults
                Organizations:
                        - *Org1
                        - *Org2
Organizations:

    - &OrdererOrg
        Name: OrdererOrg
        ID: OrdererMSP
        
        MSPDir: /home/zym/fabric-ws/simple-demo/crypto-config/ordererOrganizations/simple-network.com/msp
        
    - &Org1
        Name: Org1MSP
        ID: Org1MSP
        MSPDir: /home/zym/fabric-ws/simple-demo/crypto-config/peerOrganizations/org1.simple-network.com/msp
        AnchorPeers:
                - Host: peer0.org1.simple-network.com
                - Port: 7051
    - &Org2
        Name: Org2MSP
        ID: Org2MSP
        MSPDir: /home/zym/fabric-ws/simple-demo/crypto-config/peerOrganizations/org2.simple-network.com/msp
        AnchorPeers:
                - Host: peer0.org2.simple-network.com
                - Port: 7051
     
Orderer: &OrdererDefaults

    OrdererType: solo

    Addresses:
        - orderer.simple-network.com:7050

    BatchTimeout: 2s

    BatchSize:

        MaxMessageCount: 10

        AbsoluteMaxBytes: 98 MB

        PreferredMaxBytes: 512 KB

    Kafka:
        Brokers:
            - 127.0.0.1:9092

    Organizations:

Application: &ApplicationDefaults

    Organizations:

2.1 生成创世块

根据configtx.yaml的配置生成创世区块

configtxgen -profile TestTwoOrgsOrdererGenesis -outputBlock ./orderer.genesis.block

2.2 创建channel文件

根据configtx.yaml的配置生成名为testChannel的channel文件

configtxgen -profile TestTwoOrgsChannel  -outputCreateChannelTx ./testchannel.tx -channelID testchannel

2.3 创建锚点文件

根据configtx.yaml的配置生成锚点文件

//org1的锚点文件
configtxgen -profile TestTwoOrgsChannel -outputAnchorPeersUpdate ./Org1MSPanchors.tx -channelID testchannel -asOrg Org1MSP
//org2的锚点文件
configtxgen -profile TestTwoOrgsChannel -outputAnchorPeersUpdate ./Org2MSPanchors.tx -channelID testchannel -asOrg Org2MSP

3.启动Order节点

编辑Order节点配置信息文件，可以使用Fabric中源码提供的模板进行修改。
拷贝模板文件到order目录中：

 cd  /home/zym/fabric-ws/simple-demo/order
 
 cp ~/go/src/github.com/hyperledger/fabric/sampleconfig/orderer.yaml  .

修改orderer.yaml文件， 下面是修改以后的内容：

    LedgerType: file

    ListenPort: 7050

    Version:

在orderer.yaml所在目录运行如下命令启动orderer:

orderer start

4.启动peer节点

创建一个peer目录，将Fabirc源码中的示例配置文件拷贝中peer0-org1目录中：

mkdir -p /home/zym/fabric-ws/simple-demo/peer0-org1

cd /home/zym/fabric-ws/simple-demo/peer0-org1

cp ~/go/src/github.com/hyperledger/fabric/sampleconfig/core.yaml  .

修改配置文件，修改后的内容如下：

logging:

    peer:       debug

    cauthdsl:   warning
    gossip:     warning
    ledger:     info
    msp:        warning

在core.yaml所在文件夹内执行一下命令启动order节点:

export set FABRIC_FCG_PATH=/home/zym/fabric-ws/simple-demo/peer0-org1/
peer node start >> log_peer.log 2>&1 &

5.创建通道

首先切换到simple-demo目录, 然后在simple-demo下执行后续操作：

cd ~/fabric-ws/simple-demo

第一步：创建通道

export set CORE_PEER_LOCALMSPID=Org1MSP

export set CORE_PEER_MSPCONFIGPATH=/home/zym/fabric-ws/simple-demo/crypto-config/peerOrganizations/org1.simple-network.com/users/[email protected]/msp

peer channel create -t 50 -o orderer.simple-network.com:7050 -c  testchannel -f /home/zym/fabric-ws/simple-demo/order/testchannel.tx

第二步：让已经运行的peer加入到通道中

export set CORE_PEER_LOCALMSPID=Org1MSP

export set CORE_PEER_MSPCONFIGPATH=/home/zym/fabric-ws/simple-demo/crypto-config/peerOrganizations/org1.simple-network.com/users/[email protected]/msp
export set CORE_PEER_ADDRESS=peer0.org1.simple-network.com:7051

peer  channel join -b /home/zym/fabric-ws/simple-demo/testchannel.block

第三步：更新锚节点

export set CORE_PEER_LOCALMSPID=Org1MSP

export set CORE_PEER_MSPCONFIGPATH=/home/zym/fabric-ws/simple-demo/crypto-config/peerOrganizations/org1.simple-network.com/users/[email protected]/msp
export set CORE_PEER_ADDRESS=peer0.org1.simple-network.com:7051

peer channel update -o orderer.simple-network.com:7050 -c testchannel -f /home/zym/fabric-ws/simple-demo/order/Org1MSPanchors.tx

6.部署和调用chaincode

我们这里测试部署Fabric源码自带的Chaincode：

$GOPATH/src/github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02

第一步：部署chaincode代码

export set CORE_PEER_LOCALMSPID=Org1MSP

export set CORE_PEER_MSPCONFIGPATH=/home/zym/fabric-ws/simple-demo/crypto-config/peerOrganizations/org1.simple-network.com/users/[email protected]/msp
export set CORE_PEER_ADDRESS=peer0.org1.simple-network.com:7051

peer chaincode install -n r_test_cc6 -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02

第二步：部署实例化chaincode代码

export set CORE_PEER_LOCALMSPID=Org1MSP

export set CORE_PEER_MSPCONFIGPATH=/home/zym/fabric-ws/simple-demo/crypto-config/peerOrganizations/org1.simple-network.com/users/[email protected]/msp
export set CORE_PEER_ADDRESS=peer0.org1.simple-network.com:7051

peer chaincode instantiate -o orderer.simple-network.com:7050 -C testchannel -n r_test_cc6 -v 1.0    -c '{"Args":["init", "a", "100", "b", "200"]}'  -P "OR ('Org1MSP.member', 'Org2MSP.member')"

第三步：调用chaincode写入

export set CORE_PEER_LOCALMSPID=Org1MSP

export set CORE_PEER_MSPCONFIGPATH=/home/zym/fabric-ws/simple-demo/crypto-config/peerOrganizations/org1.simple-network.com/users/[email protected]/msp
export set CORE_PEER_ADDRESS=peer0.org1.simple-network.com:7051

peer chaincode invoke -o orderer.simple-network.com:7050 -C testchannel -n r_test_cc6 -v 1.0    -c '{"Args":["invoke", "a", "b", "1"]}'

第四步：调用chaincode查询

export set CORE_PEER_LOCALMSPID=Org1MSP

export set CORE_PEER_MSPCONFIGPATH=/home/zym/fabric-ws/simple-demo/crypto-config/peerOrganizations/org1.simple-network.com/users/[email protected]/msp
export set CORE_PEER_ADDRESS=peer0.org1.simple-network.com:7051

peer chaincode query -o orderer.simple-network.com:7050 -C testchannel -n r_test_cc6 -v 1.0    -c '{"Args":["query", "a"]}'

7.总结

本篇文章介绍了运行一个Fabric系统所需要的步骤，包括Fabric核心模块的编译，运行和配置。同时还介绍了Fabric核心概念Channel的创建和使用，最后介绍了Fabric的智能合约安装、实例化、以及调用的方法。
