Hyperledger fabric Hyperledger结构：在运行raft网络中添加订购者

我想在正在运行的hyperledger fabric网络中添加一个新的订购者节点。我使用了etcdraft作为订购方之间的共识

我遵循了一步一步的过程。在步骤#15中提到，我必须从系统频道获取最新的配置块，并将此块用作新订购服务的创世纪块

因此，我将config块复制到通道工件文件夹[文件名：config_block.pb]，然后使用docker-compose.yaml文件启动一个新容器。作为参考，我将docker-compose.yaml文件发布在此处：

version: '2'

volumes:
  orderer6.example.com:

networks:
  byfn:

services:

  orderer6.example.com:
    image: hyperledger/fabric-orderer:latest
    environment:
      - FABRIC_LOGGING_SPEC=INFO
      - ORDERER_GENERAL_LISTENADDRESS=0.0.0.0
      - ORDERER_GENERAL_GENESISMETHOD=file
      - ORDERER_GENERAL_GENESISFILE=/var/hyperledger/orderer/orderer.genesis.block
      - ORDERER_GENERAL_LOCALMSPID=OrdererMSP
      - ORDERER_GENERAL_LOCALMSPDIR=/var/hyperledger/orderer/msp
      # enabled TLS
      - ORDERER_GENERAL_TLS_ENABLED=true
      - ORDERER_GENERAL_TLS_PRIVATEKEY=/var/hyperledger/orderer/tls/server.key
      - ORDERER_GENERAL_TLS_CERTIFICATE=/var/hyperledger/orderer/tls/server.crt
      - ORDERER_GENERAL_TLS_ROOTCAS=[/var/hyperledger/orderer/tls/ca.crt]
      - ORDERER_KAFKA_TOPIC_REPLICATIONFACTOR=1
      - ORDERER_KAFKA_VERBOSE=true
      - ORDERER_GENERAL_CLUSTER_CLIENTCERTIFICATE=/var/hyperledger/orderer/tls/server.crt
      - ORDERER_GENERAL_CLUSTER_CLIENTPRIVATEKEY=/var/hyperledger/orderer/tls/server.key
      - ORDERER_GENERAL_CLUSTER_ROOTCAS=[/var/hyperledger/orderer/tls/ca.crt]
    working_dir: /opt/gopath/src/github.com/hyperledger/fabric
    command: orderer
    container_name: orderer6.example.com
    networks:
    - byfn
    volumes:
        - ./channel-artifacts/config_block.pb:/var/hyperledger/orderer/orderer.genesis.block
        - ./crypto-config/ordererOrganizations/example.com/orderers/orderer6.example.com/msp:/var/hyperledger/orderer/msp
        - ./crypto-config/ordererOrganizations/example.com/orderers/orderer6.example.com/tls/:/var/hyperledger/orderer/tls
        - orderer6.example.com:/var/hyperledger/production/orderer
    ports:
    - 13050:7050

最后，我使用以下命令运行orderer服务：

docker-compose -f orderer6.yaml up 

容器启动，几秒钟后崩溃。容器的日志文件显示：

订购方的详细信息日志位于中

我的方法有什么问题？我使用了byfn网络作为我的测试平台，运行：

/byfn up-o etcdraft

---

装载到新Order容器的卷存在问题。它正在为新的订购者使用现有的卷，因为您可能一直在拉下“byfn.sh”脚本，然后再次使用它来启动网络

转到

docker compose

文件，该文件用于启动新的订购者节点。检查文件顶部的

volumes

部分以及实际装入的容器定义中的内容：

卷：
order6.example.com：

及

-order6.example.com:/var/hyperledger/production/order

将正在创建和装入的卷的名称更改为全新名称。官方文件中提到的每一个步骤在此后都很有效
