hyperledger fabric环境搭建

生成秘钥

配置文件：crypto-config.yaml
首先，应该将整个网络的结构在该配置文件中定义好。cryptogen工具将按照网络定义分别为不同的node生成相应的公私钥文件，存放在crypto-config目录下。

cryptogen generate --config=./crypto-config.yaml
res=$?
if [ $res -ne 0 ]; then
  echo "Failed to generate certificates..."
  exit 1
fi

生成完成**之后，记得将对应**分配给node。例如，如果使用docker作为node，则记得用sed命令替换docker配置文件中的**。

生成配置区块/transaction

配置文件：configtx.yaml

genesis block

configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block
res=$?
if [ $res -ne 0 ]; then
  echo "Failed to generate orderer genesis block..."
  exit 1
fi

channel configuration transaction

configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME
res=$?
if [ $res -ne 0 ]; then
  echo "Failed to generate channel configuration transaction..."
  exit 1
fi

anchor peer configuration transaction

configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP
res=$?
if [ $res -ne 0 ]; then
  echo "Failed to generate channel configuration transaction..."
  exit 1
fi
