多机部署fabric kafka共识

1. 角色分配

主机1 主机 2
Org1 peer0 1 Org2 peer 0 1
Orderer 0 1 Orderer 2
kafka 0 1 kafka 2 3
zookeeper 0 1 zookeeper 2

2. 配置文件生成及准备yaml文件

2.1 修改配置文件

configtx-kafka.yaml

Addresses:
        - orderer0.example.com:7050
        - orderer1.example.com:8050
        - orderer2.example.com:7050
Kafka:
        # Brokers: A list of Kafka brokers to which the orderer connects. Edit
        # this list to identify the brokers of the ordering service.
        # NOTE: Use IP:port notation.
        Brokers:
            - kafka0:9092
            - kafka1:10092
            - kafka2:9092
            - kafka3:10092

crypto-config-kafka.yaml

OrdererOrgs:
  # ---------------------------------------------------------------------------
  # Orderer
  # ---------------------------------------------------------------------------
  - Name: Orderer
    Domain: example.com
    CA:
        Country: US
        Province: California
        Locality: San Francisco
    # ---------------------------------------------------------------------------
    # "Specs" - See PeerOrgs below for complete description
    # ---------------------------------------------------------------------------
    Specs:
      - Hostname: orderer0
      - Hostname: orderer1
      - Hostname: orderer2

2.2 生成配置文件

./generateArtifacts.sh mychannel kafka

分步执行操作如下：
1、生成公私钥和证书
[centos@jiliguo e2e_cli]$ ../../release/linux-amd64/bin/cryptogen generate --config=./crypto-config-kafka.yaml
2、生成创世区块
cp configtx-raft.yaml configtx.yaml
../../release/linux-amd64/bin/configtxgen -profile TwoOrgsOrdererGenesis  -outputBlock ./channel-artifacts/genesis.block
3、生成Channel配置区块
CONFIGTXGEN=../../release/linux-amd64/bin/configtxgen
CHANNEL_NAME=mychannel
$CONFIGTXGEN -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME
4、更新锚节点
$CONFIGTXGEN -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP
$CONFIGTXGEN -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP

2.3 zookeeper、kafka等yaml文件生成

其中 ZOO_MY_ID 表示 ZK 服务的 id, 它是1-255 之间的整数, 必须在集群中唯一. ZOO_SERVERS 是ZK 集群的主机列表.

1、2181：对client端提供服务
2、3888：选举leader使用
3、2888：集群内机器通讯使用（Leader监听此端口）
zookeeper

version: '2'
services:
  zookeeper0:
    container_name: zookeeper0
    image: hyperledger/fabric-zookeeper
    restart: always
    ports:
      - 2181:2181
      - 2888:2888
      - 3888:3888
    environment:
      - ZOO_MY_ID=1
      - ZOO_SERVERS=server.1=0.0.0.0:2888:3888 server.2=zookeeper1:5888:4888 server.3=zookeeper2:2888:3888
    extra_hosts:
      - "zookeeper0:0.0.0.0"
      - "zookeeper1:192.168.9.110"
      - "zookeeper2:192.168.9.96"
      - "kafka0:192.168.9.110"
      - "kafka1:192.168.9.110"
      - "kafka2:192.168.9.96"
      - "kafka3:192.168.9.96"

注意：ZOO_SERVERS中本机的地址一律写出0.0.0.0:2888:3888；端口号是2888:3888，不是映射到host的端口号,其他写映射的ip和端口

kafka

version: '2'

services:
  kafka0:
    container_name: kafka0
    image: hyperledger/fabric-kafka
    restart: always
    environment:
      - KAFKA_BROKER_ID=0
      - KAFKA_MIN_INSYNC_REPLICAS=2
      - KAFKA_DEFAULT_REPLICATION_FACTOR=3
      - KAFKA_ZOOKEEPER_CONNECT=zookeeper0:2181,zookeeper1:3181,zookeeper2:2181
      - KAFKA_MESSAGE_MAX_BYTES=103809024 # 99 * 1024 * 1024 B
      - KAFKA_REPLICA_FETCH_MAX_BYTES=103809024 # 99 * 1024 * 1024 B
      - KAFKA_UNCLEAN_LEADER_ELECTION_ENABLE=false
      - KAFKA_ADVERTISED_HOST_NAME=192.168.9.110
      - KAFKA_ADVERTISED_PORT=9092
    ports:
      - 9092:9092
    extra_hosts:
      - "zookeeper0:192.168.9.110"
      - "zookeeper1:192.168.9.110"
      - "zookeeper2:192.168.9.96"
      - "kafka0:192.168.9.110"
      - "kafka1:192.168.9.110"
      - "kafka2:192.168.9.96"
      - "kafka3:192.168.9.96"

注意：一定要配KAFKA_ADVERTISED_HOST_NAME和KAFKA_ADVERTISED_PORT，为host的IP和映射到host的端口

orderer

version: '2'

services:
  orderer2.example.com:
    container_name: orderer2.example.com
