官方的first-network执行一个脚本单机 docker 就可以启动 fabric 网络环 很多书和网络上也都是基于first-network教学,下面教程基于拆解first-network,不但对我们更深入了解 fabric 网络搭建有很大帮助,也有利于我们真实生产环境的搭建操作。

主机列表

节点 IP
order.example.com 192.168.11.11
peer0.org0.example.com 192.168.11.12
peer1.org0.example.com 192.168.11.13
peer0.org1.example.com 192.168.11.14
peer1.org1.example.com 192.168.11.15

由于域名并非真实解析的公网,所以需要将以上加入各个主机的/etc/hosts

环境依赖安装

以下依赖安装没有特别说明需要在各个主机中安装操作

docker 安装

apt-get update
apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
add-apt-repository \
   "deb [arch=arm64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"
apt-get update
apt-get install docker-ce docker-ce-cli containerd.io
docker --version

docker-compose 安装

curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
docker-compose --version

Golang 安装

 wget https://dl.google.com/go/go1.13.4.linux-amd64.tar.gz
 tar -C /usr/local -xzf go1.13.4.linux-amd64.tar.gz

设置 go 环境变量

vi ~/.bashrc

添加

export PATH=$PATH:/usr/local/go/bin

执行source ~/.bashrc

Node.js 安装

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
apt install nodejs

安装示例、二进制文件和 Docker 镜像

 mkdir fabric && cd fabric && curl -sSL https://bit.ly/2ysbOFE | bash -s

将 bin 目录加入到 PATH:

export PATH=$PATH:~/fabric/bin

生成公私钥和证书

我们把order.example.com这台主机直接作为 cli 主机,在上面进行客户端操作。

crypto-config.yaml配置:

OrdererOrgs:
    - Name: Orderer
      Domain: example.com
      EnableNodeOUs: true
      Specs:
          - Hostname: orderer
          - Hostname: orderer2
          - Hostname: orderer3
          - Hostname: orderer4
          - Hostname: orderer5

PeerOrgs:
    - Name: Org1
      Domain: org1.example.com
      EnableNodeOUs: true
      Template:
          Count: 2
      Users:
          Count: 1
    - Name: Org2
      Domain: org2.example.com
      EnableNodeOUs: true
      Template:
          Count: 2
      Users:
          Count: 1

执行命令:

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

生成 Orderer 和两个 Org 的公私钥和证书 ##生成创世区块和 Channel 配置 ###生成创世区块 configtxgen来生成配置区块和配置交易,创世块用于 Ordering 服务,配置网络中的策略configtx.yaml配置:

#   SECTION: Capabilities
#
#   - This section defines the capabilities of fabric network. This is a new
#   concept as of v1.1.0 and should not be utilized in mixed networks with
#   v1.0.x peers and orderers.  Capabilities define features which must be
#   present in a fabric binary for that binary to safely participate in the
#   fabric network.  For instance, if a new MSP type is added, newer binaries
#   might recognize and validate the signatures from this type, while older
#   binaries without this support would be unable to validate those
#   transactions.  This could lead to different versions of the fabric binaries
#   having different world states.  Instead, defining a capability for a channel
#   informs those binaries without this capability that they must cease
#   processing transactions until they have been upgraded.  For v1.0.x if any
#   capabilities are defined (including a map with all capabilities turned off)
#   then the v1.0.x peer will deliberately crash.

                - *Org2

执行命令:

 mkdir channel-artifacts && configtxgen -profile SampleMultiNodeEtcdRaft -channelID sys-channel -outputBlock ./channel-artifacts/genesis.block

生成了系统通道的创世块,sys-channel是我们设置的系统创世块名,./channel-artifacts/genesis.block该创世区块在后面的 Orderer 启动和网络配置会使用到. ###生成通道配置 Channel 配置区块,新建 ID 为mychannel的通道,指定通道成员以及访问策略.

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

锚节点更新文件

锚节点负责代表组织与其他组织中的节点进行 Gossip 通信

configtxgen -configPath ./ -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID mychannel -asOrg Org1MSP
configtxgen -configPath ./ -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID mychannel -asOrg Org2MSP

到此创世块和 channel 配置已完成:

channel-artifacts/
├── channel.tx
├── genesis.block
├── Org1MSPanchors.tx
└── Org2MSPanchors.tx

配置启动 Order 节点 ###配置 docker-compose file

启动 Order:

docker-compose -f docker-compose-order-etcdraft.yaml up -d

配置启动 Peer 节点

拷贝 crypto-config 、channel-artifacts 目录到其他节点服务器 ##配置 docker-compose file 使用 couchdb 作为数据库 docker-compose-peer-couch.yaml:

version: '2'

volumes:
    peer0.org1.example.com:

# networks:
#   byfn:

services:
    couchdb:
        container_name: couchdb
        image: hyperledger/fabric-couchdb
        # Populate the COUCHDB_USER and COUCHDB_PASSWORD to set an admin user and password
        # for CouchDB.  This will prevent CouchDB from operating in an "Admin Party" mode.
        environment:
            - COUCHDB_USER=
            - COUCHDB_PASSWORD=
        # Comment/Uncomment the port mapping if you want to hide/expose the CouchDB service,
        # for example map it to utilize Fauxton User Interface in dev environments.
        network_mode: 'host'
        # networks:
        #   - byfn
        ports:
            - '5984:5984'

    peer0.org1.example.com:
        container_name: peer0.org1.example.com
        extends:
            file: base/peer-base.yaml
            service: peer-base
        #    dns_search: .
        environment:
            - GODEBUG=netdns=go

        network_mode: 'host'
        ports:
            - 7051:7051

在节点服务器上运行节点 :

docker-compose -f docker-compose-peer-couch.yaml up -d

docker-compose-peer-couch.yaml配置中的 peer0、org1、CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESSO、rg1MSP 替换成不同节点服务器,然后如上同样的步骤在各个节点服务器中执行命令。

初始化 Fabric 网络 ###运行 cli 容器

我们后面会通过进入 cli 容器中来操作 Fabric 网络的一些客户端,其中 peer 节点的一些操作比如加入网络等实际生产环境也可以在 peer 节点服务器中的容器中操作。docker-compose-cli.yaml:

version: '2'

networks:
    byfn:

services:
    cli:
        container_name: cli
        image: hyperledger/fabric-tools:latest
        tty: true
        stdin_open: true
        environment:
            - SYS_CHANNEL=sys-channel
            - GOPATH=/opt/gopath
            - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
            - FABRIC_LOGGING_SPEC=INFO
            - CORE_PEER_ID=cli
            - CORE_PEER_ADDRESS=peer0.org1.example.com:7051
            - CORE_PEER_LOCALMSPID=Org1MSP
            - CORE_PEER_TLS_ENABLED=true
            - CORE_PEER_TLS_CERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.crt
            - CORE_PEER_TLS_KEY_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.key
            - 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
            - CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
        working_dir: /opt/gopath/src/github.com/hyperledger/fabric/peer
        command: /bin/bash
        volumes:
            - /var/run/:/host/var/run/
            - ./chaincode:/opt/gopath/src/github.com/chaincode
            - ./crypto-config:/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/
            - ./scripts:/opt/gopath/src/github.com/hyperledger/fabric/peer/scripts/
            - ./channel-artifacts:/opt/gopath/src/github.com/hyperledger/fabric/peer/channel-artifacts
        network_mode: 'host'

启动 cli 容器 :

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

创建 Channel

要进入 cli 容器内部,在里面创建 Channel:

docker exec -it cli bash

前面创建 Channel 的配置区块时,指定了 Channel 的名字是mychannel这里必须创建同样名字的 Channel:

ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
peer channel create -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/channel.tx --tls true --cafile $ORDERER_CA

第一行是环境变量配置,指定证书的位置,是本地证书路径映射映射到容器中的路径。

Peer 加入 Channel

上面 docker-compose-cli.yaml 中我们已经设置了默认的环境变量是 peer0.org1.example.com 的节点,先将 peer0.org1 加入到 channel:

peer channel join -b mychannel.block

添加其他几个节点同样的命令,但是要修改对于应节点的环境变量,比如要将 peer0.org2 加入到 channel 中执行如下:

CORE_PEER_ADDRESS=peer0.org2.example.com:7051
CORE_PEER_LOCALMSPID=Org2MSP
CORE_PEER_TLS_CERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/server.crt
CORE_PEER_TLS_KEY_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/server.key
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
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
peer channel join -b mychannel.block

更新锚节点

上面通过configtx.yaml我们已经配置并生成了 Org1 的锚节点为 peer0.org1,Org2 的锚节 peer0.org2,接下来更新锚节点:

ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
CORE_PEER_ADDRESS=peer0.org1.example.com:7051
CORE_PEER_LOCALMSPID=Org1MSP
CORE_PEER_TLS_CERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.crt
CORE_PEER_TLS_KEY_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.key
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
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
peer channel update -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/Org1MSPanchors.tx --tls true --cafile $ORDERER_CA

peer0.org2 同样的命令,只是设置不同的环境变量:

ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
CORE_PEER_ADDRESS=peer0.org2.example.com:7051
CORE_PEER_LOCALMSPID=Org2MSP
CORE_PEER_TLS_CERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/server.crt
CORE_PEER_TLS_KEY_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/server.key
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
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
peer channel update -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/Org2MSPanchors.tx --tls true --cafile $ORDERER_CA

安装和实例化链码

安装链码

这里直接用官方github.com/chaincode/chaincode_example02作为示例链码安装,安链需要安装在各个相关的 peer 上,和上面操作类似,可以在 CLI 容器中设置好环境变量,然后执行peer chaincode install,这里给出 peer0.org1 的示例,:

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

实例化链码

在通道上实例化链码。这会在通道上初始化链码,为链码指定背书策略,然后为目标节点启动链码容器。同时指定 -P "OR ('Org1MSP.member','Org2MSP.member')" 作为策略。

CORE_PEER_LOCALMSPID=Org1MSP
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile $ORDERER_CA -C mychannel -n mycc -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}' -P "OR ('Org1MSP.peer','Org2MSP.peer')"

验证链码

通过节点查询,结果返回 100,说明链码实例化成功:

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

在节点的 docker 容器中会多一个链码容器:

CONTAINER ID        IMAGE                                                                                                  COMMAND                  CREATED             STATUS              PORTS               NAMES

到此一个可以用于实际生产环境的多机 Hyperledger Fabric 区块链网络部署就完成了。
