1.修改configtx.yaml
将OrdererType修改成kafka
修改Addresses，这里我是设置了三个orderer：orderer0、orderer1、orderer2
修改Kafka的Brokers，这里我使用三台虚拟机运行kafka
################################################################################## SECTION: Orderer## - This section defines the values to encode into a config transaction or# genesis block for orderer related parameters#################################################################################Orderer: &OrdererDefaults # Orderer Type: The orderer implementation to start # Available types are "solo" and "kafka" OrdererType: kafka Addresses: - orderer0.example.com:7050 - orderer1.example.com:7050 - orderer2.example.com:7050 # Batch Timeout: The amount of time to wait before creating a batch BatchTimeout: 2s # Batch Size: Controls the number of messages batched into a block BatchSize: # Max Message Count: The maximum number of messages to permit in a batch MaxMessageCount: 10 # Absolute Max Bytes: The absolute maximum number of bytes allowed for # the serialized messages in a batch. AbsoluteMaxBytes: 98 MB # Preferred Max Bytes: The preferred maximum number of bytes allowed for # the serialized messages in a batch. A message larger than the preferred # max bytes will result in a batch larger than preferred max bytes. PreferredMaxBytes: 512 KB 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.

2.修改crypto-config.yaml
修改Specs，设置三个orderer：orderer0、orderer1、orderer2
# ---------------------------------------------------------------------------# "OrdererOrgs" - Definition of organizations managing orderer nodes# ---------------------------------------------------------------------------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# ---------------------------------------------------------------------------# "PeerOrgs" - Definition of organizations managing peer nodes# ---------------------------------------------------------------------------
3.生成channe-artifacts和crypto-config文件
在e2e_cli目录下，打开命令终端，执行如下命令：
./generateArtifacts.sh
执行完毕后，会在e2e_cli目录下生成channel-artifacts和crypto-config两个文件夹。内容分别如下：
channel-artifacts:
channel-artifacts.png
crypto-config/ordererOrgnizations/example.com/orderers目录如下：
orderers.png
生成的channel-artifacts和crypto-config文件夹要拷贝到其他节点，确保不同org使用同一套文件
4.配置zookeeper.yaml
创建zookeeper.yaml（我创建了三个zookeeper节点zookeeper0、zookeeper1、zookeeper2，所以也创建了三个配置文件：zookeeper0.yaml、zookeeper1.yaml、zookeeper2.yaml），我们以zookeeper0.yaml为例说明
修改
service名称为zookeeper0修改
container_name为zookeeper0修改
-ZOO_MY_ID等于1（此ID是zookeeper节点在集群中的唯一标识，不可重复，我定义的是1 、 2 、3）修改
extra_hosts中的zookeeper0映射的ip为0.0.0.0（同理zookeeper1/2.yaml文件中zookeeper1/2映射的ip为0.0.0.0）
# Copyright IBM Corp.

ZOO_MY_ID是zookeeper节点在集群中的唯一标识，不可重复，我分别定义成1 、 2 、3 - ZOO_SERVERS=server.1=zookeeper0:2888:3888 server.2=zookeeper1:2888:3888 server.3=zookeeper2:2888:3888 ports: - "2181:2181" - "2888:2888" - "3888:3888" extra_hosts: - "zookeeper0:0.0.0.0" #zookeeper0.yaml文件中zookeeper0映射的ip改成0.0.0.0， - "zookeeper1:10.10.12.31" - "zookeeper2:10.10.12.32" - "kafka0:10.10.12.30" - "kafka1:10.10.12.31" - "kafka2:10.10.12.32"
5.修改kafka.yaml
创建kafka.yaml文件（我创建了3个kafka节点kafka0、kafka1、kafka2，所以也创建了三个配置文件kafka0.yaml、kafka1.yaml、kafka2.yaml），以kafka0.yaml为例进行说明
service名称修改成kafka0container_name名称修改成kafka0添加
hostname，并将名称改为kafka0修改
KAFKA_BROKER_ID=0（此ID为kafka节点在集群中的唯一标识，不可重复，我定义的是0\1\2）

6.修改orderer.yaml
创建orderer.yaml（我创建了三个orderer节点：orderer0、orderer1、orderer2，所以也创建了三个orderer配置文件：orderer0.yaml、orderer1.yaml、orderer2.yaml）。这里以orderer0.yaml为例进行说明
service名称改为orderer0.example.comcontainer_name名称改为orderer0.example.comORDERER_KAFKA_BROKERS集合改成[10.10.12.30:9092,10.10.12.31:9092,10.10.12.32:9092]（此处为三个kafka节点的地址）

7.修改peer.yaml
创建peer.yaml（我创建了2个org，每个org有两个peer，所以相应地创建了四个peer.yaml文件：docker-compose-peer0org1.yaml、docker-compose-peer1org1.yaml、docker-compose-peer0org2.yaml、docker-compose-peer0org2.yaml）。这里以docker-compose-peer0org1.yaml为例进行说明
需要特别说明的是，environment中的路径每个节点未必相同（peer0、peer1、org1、org2）
