Hyperledger Fabric远程多节点环境部署过程

阅读更多

        很多Hyperledger Fabric的初学者会从官方的github上clone一份代码到本地,运行其中的demo(fabric下的e2e_cli或者fabric-samples下的first-network),在本地利用虚拟机搭建fabric网络来进行开发测试,那种方式按照官方的wiki以及md教程比较容易,只需要安装好必要的基础软件如docker,docker-compose,go...即可通过提供的.yaml和.sh脚本快速的运行起来。但是对于准生产或者生产环境就不能这么简单的完成了,如果不购买第三方提供的Baas服务,则需要自己一个个的进行安装配置,在这个手动操作的过程中也会遇到不少问题,在此将我在某家银行现场一步步安装配置搭建Fabric网络的准生产环境的过程分享出来,希望能够对有需要的朋友有所帮助。

 

首先说明下硬件环境的一个基本配置:4台CentOS 7.5云主机,4核CPU+16G内存,5M带宽。

 

如果将4台机器分别编号为A,B,C,D,那么他们各自需要安装的软件及充当的角色如下:


 

下面依次介绍需要安装的这些软件安装及配置

 

1、安装JDK-1.8 

关于JDK的安装配置,这里不做过多阐述

 

2、安装Zookeeper-3.4.12(以机器A为例)

  1. 将安装包zookeeper-3.4.12.tar.gz上传到当前登录用户工作空间soft目录下;
  2. 解压缩安装包到目标安装目录下并进入到conf目录,复制一份zoo_sample.cfg改名为zoo.cfg;
  3. 编辑zoo.cfg配置文件,对配置信息做如下修改

    dataDir=/appdata/zookeeper

    server.1=A:2888:3888

    server.2=B:2888:3888

    server.3=C:2888:3888

    说明:

    2181是对外通讯的端口

    2888是集群内机器通讯使用的端口(Leader监听此端口)

    3888是选举leader时监听的端口

  4. 创建/appdata/zookeeper目录并授权(chown -R user:group /appdata/zookeeper)给当前登录用户,在该目录下创建myid配置文件,写入对应的值(机器A写入1,机器B写入2,机器C写入3)
  5. 切换到zookeeper安装目下的bin目录,执行如下命令启动server
    zkServer.sh start
  6. 默认的日志文件存放在/appdata/zookeeper目录下面
    tail -f /appdata/zookeeper/version-2/log.100000001

3、安装kafka-2.11-1.0.1.tgz(以机器A为例)

  1. 将安装包kafka_2.11-1.0.1.tgz上传到当前登录用户工作空间soft目录下;
  2. 解压缩安装包到目标安装目录下并进入到config目录;
  3. 编辑server.properties,对配置信息做如下修改

     

    #kafka broker id,4台主机分别为1,2,3,4
    
    broker.id=1
    
    listeners=PLAINTEXT://A:9092
    
    #kafka主机名
    
    host.name=A
    
    #zookeeper server列表
    
    zookeeper.connect=A:2181,B:2181,C:2181 

     

  4. 切换到kafka安装目录下,执行如下命令启动kafka
    nohup bin/kafka-server-start.sh config/server.properties & 
  5. 默认的日志文件存放在/tmp/kafka-logs目录下,如果想要自己指定日志目录,用如下命令启动
    nohup ./bin/kafka-server-start.sh ./config/server.properties >logs/kafka.log 2>1 & 
    # 注意logs/kafka.log需要手动创建好,不然会报 -bash: logs/kafka.log: No such file or directory错误

 

4、安装Docker

可以参考我的另一篇博文《Ubuntu 16.04环境下安装Docker17.12.0-ce详细步骤

 

5、安装Go

说明:要通过哪台机器连接peer节点进行chaincode的安装才需要在哪台机器上安装go

 

  1. 将安装包go1.9.linux-amd64.tar.gz上传到当前登录用户工作空间soft目录下;
  2. 解压缩安装包到目标安装目录下,如:/opt/go
  3. 编辑当前用户的环境变量 vi ~/.bash_profile,在文件最后追加如下环境变量配置
    export GOPATH=/opt/gopath
    export GOROOT=/opt/go
    export PATH=$PATH:/opt/go/bin
  4. 重新编译载入环境变量
    source ~/.bash_profile
  5. 执行go version检验go是否安装成功

6、安装Fabric Binaries

  1. 将安装包hyperledger-fabric-linux-amd64-1.1.0.tar.gz上传到当前登录用户工作空间soft目录下;
  2. 解压缩安装包到/home/username/fabric目录下,Fabric binaries文件列表如下:

    fabric

    ├── bin

    │       ├── configtxgen          //创始区块生成工具

    │       ├── configtxlator         //channel修改工具

    │       ├── cryptogen            //pki证书生成工具

    │       ├── get-docker-images.sh

    │       ├── orderer                 //orderer节点运行程序

    │       └── peer                     //peer节点运行程序

    └── config

             ├── configtx.yaml        //创始区块定义文件

             ├── core.yaml             //peer配置文件

             └── orderer.yaml         //orderer配置文件

7、生成msp证书文件

  1. 定义部署orderer和peer各机构的msp结构模板crypto-config.yaml,可以参考fabric官方源码下的e2e_cli示例代码进行修改配置

    #    Template:
    #      Count: 2
    #    Users:
    #      Count: 1
     
  2. 生成orderer和peer的msp文件
    ./bin/cryptogen generate --config=./crypto-config.yaml
     

8、生成创始区块和channel定义

  1. 创始区块和channel定义在configtx.yaml文件中,内容如下:

  2. 手动创建一个文件夹channel-artifacts
    sudo mkdir channel-artifacts
     
  3. 执行命令生成创世区块
    sudo bin/configtxgen -profile OrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block
     
  4. 执行命令生成channel定义
    sudo bin/configtxgen -profile OrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID mychannel
     

9、配置orderer.yaml

  1. 拷贝orderer机器A上的crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp/和crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/目录到fabric/bin目录下
  2. 拷贝orderer机器B上的crypto-config/ordererOrganizations/example.com/orderers/orderer1.example.com/msp/和crypto-config/ordererOrganizations/example.com/orderers/orderer1.example.com/tls/目录到fabric/bin目录下
  3. 分别拷贝orderer机器A,B上的channel-artifacts/genesis.block到fabric/bin目录下
  4. 分别拷贝orderer机器A,B上的config/orderer.yaml到fabric/bin目录下,进行编辑
    32行 Enabled: false	改为:true		
    
    64行 GenesisMethod: provisional	改为:file
    
    76行 GenesisFile: genesisblock	改为:genesis.block
    
    137行 Location: /var/hyperledger/production/orderer	改为:/data/hyperledger/production/orderer
     

10、启动orderer节点

 

nohup ./orderer [./orderer.yaml] >logs/orderer.log 2>1 &

 

 

11、导入Fabric chaincode运行环境镜像

 在C,D两台peer机器上导入chaincode运行环境相关的基础镜像。

docker load --input fabric-ccenvx86_64-1.1.0.tar
docker load --input fabric-javaenvx86_64-1.1.0.tar
docker load --input fabric-baseos.tar
docker load --input fabric-baseimage.tar

查看已安装
docker images | grep -E *\(1.1.0\|0.4.6\)

 

 

12、配置core.yaml

  1. 拷贝peer机器C上的crypto-config/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/msp/和crypto-config/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/目录到fabric/bin目录下
  2. 拷贝peer机器D上的crypto-config/peerOrganizations/org2.example.com/peers/peer1.org2.example.com/msp/和crypto-config/peerOrganizations/org2.example.com/peers/peer1.org2.example.com/tls/目录到fabric/bin目录下
  3. 分别拷贝peer机器C,D上的config/core.yaml到fabric/bin目录下,进行编辑
    262行 enabled:  false		改为:true
    
    300行 fileSystemPath: /var/hyperledger/production	改为:/data/hyperledger/production
    
    328行 localMspId: DEFAULT	改为:Org2MSP
     

13、启动peer节点

nohup ./peer [./core.yaml] node start >logs/peer.log 2>1 &

 

14、Fabric网络初始化-创建通道

以在orderer机器A为例

  1. 切换当前目录到fabric/bin下面
  2. 拷贝orderer机器A上的crypto-config目录到fabric/bin下面
  3. 拷贝orderer机器A上的channel-artifacts/channel.tx到fabric/bin目录下
  4. 执行如下命令设置环境变量
    #### 命令行执行
    #### 环境变量设置
    export CORE_PEER_ADDRESS=peer0.org2.example.com:7051
    export CORE_PEER_LOCALMSPID=Org2MSP
    export CORE_PEER_TLS_ENABLED=true
    export CORE_PEER_TLS_CERT_FILE=crypto-config/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/server.crt
    export CORE_PEER_TLS_KEY_FILE=crypto-config/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/server.key
    export CORE_PEER_TLS_ROOTCERT_FILE=crypto-config/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
    export CORE_PEER_MSPCONFIGPATH=crypto-config/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
     
  5. 执行如下命令创建通道
    ./peer channel create -o orderer.example.com:7050 -c mychannel -f ./channel.tx --tls true --cafile crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
     

15、将peer节点加入通道

  1. 当前环境变量配置连接的是peer0节点,直接执行如下命令将peer0节点加入通道
    ./peer channel join -b mychannel.block
     
  2. 执行如下命令设置环境变量连接到peer1节点
    #### 命令行执行
    #### 环境变量设置
    export CORE_PEER_ADDRESS=peer1.org2.example.com:7051
    export CORE_PEER_LOCALMSPID=Org2MSP
    export CORE_PEER_TLS_ENABLED=true
    export CORE_PEER_TLS_CERT_FILE=crypto-config/peerOrganizations/org2.example.com/peers/peer1.org2.example.com/tls/server.crt
    export CORE_PEER_TLS_KEY_FILE=crypto-config/peerOrganizations/org2.example.com/peers/peer1.org2.example.com/tls/server.key
    export CORE_PEER_TLS_ROOTCERT_FILE=crypto-config/peerOrganizations/org2.example.com/peers/peer1.org2.example.com/tls/ca.crt
    export CORE_PEER_MSPCONFIGPATH=crypto-config/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
     
  3. 执行如下命令将peer1节点加入通道
    ./peer channel join -b mychannel.block
     

16、安装并实例化chaincode

  1. 准备go环境
  2. 配置环境变量以连接到某个peer节点上
  3. 切换到fabric/bin目录下安装chaincode
    ./peer chaincode install -n acctflow -v 1.0 -p github.com/hyperledger/fabric/chaincode/go/acctflow
     
  4. 实例化chaincode
    ./peer chaincode instantiate -o orderer.example.com:7050 --tls true --cafile crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n acctflow -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "OR ('Org2MSP.member')"
     

17、连接到某个peer节点进行chaincode调用

  1. 设置环境变量以连接到某个peer节点
  2. 进行chaincode写入、查询的调用
    ./peer chaincode invoke -o orderer.example.com:7050 --tls --cafile crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n acctflow -c '{"Args":["insert","{\"loanNumber\":\"1219171448700375376293400660\",\"happenDate\":\"2017/12/26\",\"currency\":\"156\",\"businessCode\":\"50099\",\"businessDesc\":\" 车款分期\",\"loanFlag\":\"D\",\"businessAmount\":950.00,\"branchNo\":\"\",\"productNo\":\"F02100900001\",\"subject\":\"1301\"}"]}'
    
    ./peer chaincode invoke -o orderer.example.com:7050 --tls --cafile crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n acctflow -c '{"Args":["query", "1219171448700375376293400660", "2017/12/26"]}'
     

至此,Fabric远程多节点环境手动部署过程全部结束!
