超级账本中的第一个网络 [英] First network in hyperledger

问题描述

我正在尝试在Hyperledger Fabric中的第一个网络上工作.使用以下文档 http://hyperledger-fabric.readthedocs.io/en/latest/build_network. html

I am trying to work on my first network in Hyperledger Fabric. Using the following documentation http://hyperledger-fabric.readthedocs.io/en/latest/build_network.html

我已经完成设置，直到 http://hyperledger-fabric.readthedocs.io/zh/latest/build_network.html#create-join-channel

I have completed the setup till http://hyperledger-fabric.readthedocs.io/en/latest/build_network.html#create-join-channel

但是当我运行

peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

我遇到错误

错误:出现意外状态:BAD_REQUEST

搜索我遇到的问题 http://hyperledgerdocs.readthedocs.io/en/latest/asset_trouble.html

因此，我尝试使用给定的新频道名称(旧频道名称= mychannel)， 我已经在cmds下面尝试过

Hence I've tried to use a new channel name as given(old channel name=mychannel), I've tried below cmds

CORE_PEER_COMMITTER_LEDGER_ORDERER=orderer:7050 peer channel create -c myc1

CORE_PEER_COMMITTER_LEDGER_ORDERER=orderer.example.com:7050 peer channel create -c myc1

CORE_PEER_COMMITTER_LEDGER_ORDERER=172.18.0.2:7050 peer channel create -c myc1

对于这三个我都出错了

错误:订购服务端点无效或缺失 用法: 对等频道创建[标志]

Error: Ordering service endpoint is not valid or missing Usage: peer channel create [flags]

此外，我还假设已创建频道，因此尝试过跳过它. 因此跑了

Also I've tried to skip it assuming the channel is already created. hence ran

peer channel join -b ./mychannel.block

但是得到了

错误:投标失败(错误:rpc错误:代码=未知desc =链码错误(状态:500，消息:由于LedgerID已经存在，无法从创始块创建分类帐))

我的操作系统是Ubuntu 16.04

推荐答案

让我们尝试确保您按照

Let's try to make sure you run thru all the steps as outlined in docs.

1. 首先，您需要在 cli 部分中编辑docker-compose-cli.yaml文件，以注释掉负责运行频道自动创建和加入流程的行:

1. First of all you need to edit your docker-compose-cli.yaml file the cli section to comment out line responsible to run automatic flow of channel creation and join:

command: /bin/bash -c './scripts/script.sh ${CHANNEL_NAME}; sleep $TIMEOUT'

例如

# command: /bin/bash -c './scripts/script.sh ${CHANNEL_NAME}; sleep $TIMEOUT'

1. 您正在使用的下一个导出频道名称:

1. Next export channel name you are working with:

export CHANNEL_NAME=mychannel

启动网络(使用60秒的默认超时):

Start the network (use default timeout of 60s):

CHANNEL_NAME=$CHANNEL_NAME docker-compose -f docker-compose-cli.yaml up -d

输入cli容器:

docker exec -it cli bash

导出环境变量:

export CHANNEL_NAME=mychannel

创建频道:

peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

加入频道:

Join the channel:

peer channel join -b mychannel.block
