使用其他同行扩展Hyperledger fabric fabcar示例时出错

Question

这是我的第一篇文章，因此我将尝试尽可能详细，并显示重现这些错误的步骤。我想用额外的对等体扩展给定的Fabcar示例，但我无法查询/调用扩展系统。如果我尝试查询系统，我会收到以下错误：

Query has completed, checking results
error from query =  Error: make sure the chaincode fabcar has been successfully instantiated and try again: getccdata mychannel/fabcar responded with error: could not find chaincode with name 'fabcar'
    at /home/hyperledger/Dokumente/Hyperledger_test/Fabric-SamplesV4/fabric-samples/fabcar/node_modules/fabric-client/lib/Channel.js:2638:24
    at <anonymous>

如果我运行docker ps -a命令，它会显示：

正如你所看到的那样，devpeer缺失了，如果你构建原始的Fabcar示例，这个同伴就会出现。

如果我为peer0运行docker logs命令，它会显示：

我重现这一结果的步骤：

在基本网络文件夹中进行了更改：

Crypto-config.yaml - 将模板计数值更改为2
Docker-compose.yml - 重复的peer0和couchdb以及更改的端口/名称

运行generate.sh文件以创建所需的加密材料
扩展start.sh文件以在整个系统中创建新对等体


    # don't rewrite paths for Windows Git Bash users
    export MSYS_NO_PATHCONV=1

    docker-compose -f docker-compose.yml down

    docker-compose -f docker-compose.yml up -d ca.example.com orderer.example.com peer0.org1.example.com couchdb

    sleep 0.2

    docker-compose -f docker-compose.yml up -d peer1.org1.example.com couchdb1

    # wait for Hyperledger Fabric to start
    # incase of errors when running later commands, issue export FABRIC_START_TIMEOUT=
    export FABRIC_START_TIMEOUT=10
    #echo ${FABRIC_START_TIMEOUT}
    sleep ${FABRIC_START_TIMEOUT}

    # Create the channel
    docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer0.org1.example.com peer channel create -o orderer.example.com:7050 -c mychannel -f /etc/hyperledger/configtx/channel.tx
    # Join peer0.org1.example.com to the channel.
    docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer0.org1.example.com peer channel join -b mychannel.block

    docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer1.org1.example.com peer channel join -b mychannel.block

运行start.sh文件以启动系统运行docker logs ca.example以获取新的ca.example私钥并更改docker-compose.yml文件中的旧密钥再次运行start.sh文件，现在您应该能够在docker环境中看到新的peer peer1的docker exec命令出错：

docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer1.org1.example.com peer channel join -b mychannel.block
2018-08-16 08:06:35.608 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
Error: genesis block file not found open mychannel.block: no such file or directory

为什么第二个对等体的起源块丢失，这个对等体是否可能无法访问该块？切换到fabcar文件夹并运行startFabric.sh文件注册管理员并注册用户尝试查询新系统，您将收到上面显示的查询错误

问题：这些步骤中是否缺少某些内容，或者为什么无法在对等设备上安装链代码并正确运行网络？

Answer 1

运行此命令时会创建mychannel.block：

    docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer0.org1.example.com peer channel create -o orderer.example.com:7050 -c mychannel -f /etc/hyperledger/configtx/channel.tx

mychannel.block在peer0.org1.example.com docker容器中创建。

当您运行此命令时，它从peer1.org1.example.com docker容器运行，因此不会有mychannel.block文件，因此您必须获取该文件，然后运行第二个对等连接命令。

  docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer1.org1.example.com peer channel join -b mychannel.block

获取命令是：

 docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer1.org1.example.com peer channel fetch 0 mychannel.block -o orderer.example.com:7050 -c mychannel

所以在加入第二个peer之前添加这个fetch命令（peer1.org1.example.com）

像这样：

# Create the channel
    docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer0.org1.example.com peer channel create -o orderer.example.com:7050 -c mychannel -f /etc/hyperledger/configtx/channel.tx
    # Join peer0.org1.example.com to the channel.
    docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer0.org1.example.com peer channel join -b mychannel.block

docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer1.org1.example.com peer channel fetch 0 mychannel.block -o orderer.example.com:7050 -c mychannel
    docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/[email protected]/msp" peer1.org1.example.com peer channel join -b mychannel.block
