无法在Hyperledger Fabric网络中设置Kaka订购者：意外的主题级元数据错误：kafka服务器：复制因子无效

标签： apache-kafka apache-zookeeper hyperledger-fabric

配置如下： 我有4台服务器。我分别在Server1，Server2，Server3中分别启动zookeeper0，zookeeper1，zookeeper2，如下所示（其中i = 0,1,2）

`docker run -itd --network="networkName" --name zookeeperi \
-e ZOO_MY_ID=i+1 \
-e ZOO_SERVERS.1=zookeeper0IP:2888:3888 \
-e ZOO_SERVERS.2=zookeeper1IP:2888:3888 \
-e ZOO_SERVERS.3=zookeeper2IP:2888:3888 \
-p 2181:2181 \
-p 2888:2888 \
-p 3888:3888 \
-v /opt/share/hyperledger/zookeeper:/tmp/zookeeper \
hyperledger/fabric-zookeeper:latest`

接下来，我要在4台分别的服务器中启动4个kafka经纪人。 （其中i = 0,1,2,3）

`docker run -itd --network="networkName" --name kafkai --restart always \
-e KAFKA_BROKER_ID=i \
-e KAFKA_ZOOKEEPER_CONNECT=zookeeper0IP:2181,zookeeper1IP,zookeeper2IP:2181 
\
-e KAFKA_LOG_RETENTION_MS=-1 \
-e KAFKA_MESSAGE_MAX_BYTES=103809024 \
-e KAFKA_REPLICA_FETCH_MAX_BYTES=103809024 \
-e KAFKA_UNCLEAN_LEADER_ELECTION_ENABLE=false \
-e KAFKA_DEFAULT_REPLICATION_FACTOR=3 \
-e KAFKA_MIN_INSYNC_REPLICAS=2 \
-e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://kafka0:9092 \
-p 9092:9092 \
-p 9093:9093 \
hyperledger/fabric-kafka:latest`

最后，我要在3个不同的服务器中启动orderer0，orderer1，orderer2。 （其中i = 0,1,2）

`docker run --rm  -it --network="networkName" --name ordereri -p 7055:7050 \
-e ORDERER_GENERAL_LOGLEVEL=debug \
-e ORDERER_GENERAL_LISTENADDRESS=0.0.0.0 \
-e ORDERER_GENERAL_GENESISMETHOD=file \
-e ORDERER_GENERAL_GENESISFILE=/opt/hyperledger/fabric/msp/crypto- 
config/ordererOrganizations/genesis.block \
-e ORDERER_GENERAL_LOCALMSPID=OrdererMSP \
-e ORDERER_GENERAL_LOCALMSPDIR=/opt/hyperledger/fabric/msp/crypto- 
config/ordererOrganizations/test.com/orderers/ordereri/msp \
-e ORDERER_GENERAL_TLS_ENABLED=false \
-e ORDERER_GENERAL_LISTENPORT=7050 \
-e CONFIGTX_ORDERER_ORDERERTYPE=kafka \
-e CONFIGTX_ORDERER_KAFKA_BROKERS= 
[kafka0:9092,kafka1:9092,kafka2:9092,kafka3:9092] \
-e ORDERER_KAFKA_RETRY_SHORTINTERVAL=1s \
-e ORDERER_KAFKA_RETRY_SHORTTOTAL=30s \
-e ORDERER_KAFKA_VERBOSE=true \
-e ORDERER_GENERAL_LEDGERTYPE=ram \
-e ORDERER_GENERAL_TLS_ENABLED=false \
--mount type=bind,source=/opt/share/hyperledger/crypto- 
config,destination=/opt/hyperledger/fabric/msp/crypto-config \
-w /opt/gopath/src/github.com/hyperledger/fabric \
hyperledger/fabric-orderer:x86_64-1.1.0 orderer`

但是订购者日志中出现以下kafka错误：

感谢您的帮助。

似乎您的“订购者”节点只是在捡起kafka2和kafka1：

2018-07-02 06:29:00.222 UTC [orderer/consensus/kafka/sarama] registerBroker -> DEBU 09e client/brokers registered new broker #2 at kafka2:9092
2018-07-02 06:29:00.222 UTC [orderer/consensus/kafka/sarama] registerBroker -> DEBU 09f client/brokers registered new broker #1 at kafka1:9092

在configtx.yaml中检查订购者和创世模块的配置。

Orderer: &OrdererDefaults

    OrdererType: kafka

    Addresses:
        - orderer.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
            - kafka1:9092
            - kafka2:9092
            - kafka3:9092

您提供了以下环境变量：CONFIGTX_ORDERER_ORDERERTYPE和CONFIGTX_ORDERER_KAFKA_BROKERS。 我不确定它们是否受支持。
