Ubuntu 16.04上的Hyperledger Fabric v1.1.0 byfn教程

Question

我使用 byfn.sh 安装了 hyperledger fabric v1.1.0-rc1。

（参考： http://hyperledger-fabric.readthedocs.io/en/lastest/build_network.html)

但我遇到了一些失败。是 Fabric CA 的问题吗？

[执行]

./byfn.sh -m generate

./byfn.sh -m up

../bin/cryptogen generate --config=./crypto-config.yaml

export FABRIC_CFG_PATH=$PWD

../bin/configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

export CHANNEL_NAME=mychannel

./bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME

我的 configtx.yaml 是 https://github.com/hyperledger/fabric-samples/blob/release-1.1/first-network/configtx.yaml

Answer 1

我遇到了类似的问题。帮助我的是重新开始。

• 关闭网络：./byfn.sh -m down
• 清理生成的工件
  • rm crypto-config
  • rm channel-artifacts

然后再次发出命令。这对我有帮助，成功创建了 channel.tx 和其他。无需更改示例中的 configtx.yaml。

Answer 2

您不必删除文件，只需确保在 Crypto Generator 部分中的步骤之前执行了 ./byfn.sh -m down
