Hyperledger Fabric1.4 手动搭建过程

一、生成证书：

#路径须要更改成本身的路径
cd ~/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network/ 
#在这里可能会报错，一般是权限问题，能够添加sudo从新执行
cryptogen generate --config=./crypto-config.yaml 
#执行完毕后，当前文件夹下会出现一个新的文件夹：crypto-config，在该文件夹下就是刚刚生成的证书.

二、生成创世区块，通道配置，锚节点配置文件

#路径须要更改成本身的路径
cd ~/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network/ 

生成创世区块
configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

  生成通道配置信息

export CHANNEL_NAME=mychannel

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

  生成两个组织的锚节点配置文件

configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP

成功后在channel-artifacts有四个文件：

channel.tx genesis.block Org1MSPanchors.tx Org2MSPanchors.tx

-- 初始区块（genesis.block）和通道配置事务（channel.tx、Org1MSPanchors.tx..）

三、启动fabric网络

sudo docker-compose -f docker-compose-cli.yaml up -d

进入cli容器

sudo docker exec -it cli bash

 

四、建立通道

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

-o 指定Orderer节点地址
-c 指定要建立的应用通道名称
-f 指定建立应用通道时所使用的应用通道交易配置文件
--tls 开启tls验证
--cafile 指定tls_ca证书的所在路径

五、将节点加入应用通道

peer channel join -b mychannel.block 

六、更新锚节点

Org1更新锚节点：
CORE_PEER_LOCALMSPID="Org1MSP" 
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt 
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp 
CORE_PEER_ADDRESS=peer0.org1.example.com:7051
ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org1MSPanchors.tx --tls true --cafile $ORDERER_CA

Org2更新锚节点：
CORE_PEER_LOCALMSPID="Org2MSP" 
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt 
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp 
CORE_PEER_ADDRESS=peer0.org2.example.com:7051

peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org2MSPanchors.tx --tls true --cafile $ORDERER_CA

七、安装示例链码

先切换到peer0.org1这个节点
CORE_PEER_LOCALMSPID="Org1MSP" 
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt 
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp 
CORE_PEER_ADDRESS=peer0.org1.example.com:7051

使用peer chaincode install命令能够安装指定的ChainCode并对其命名：

peer chaincode install -n mycc -v 1.0 -p github.com/chaincode/chaincode_example02/go

八、实例化链码

peer chaincode instantiate -o orderer.example.com:7050 --tls true --cafile $ORDERER_CA -C $CHANNEL_NAME -n mycc -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "OR('Org1MSP.member','Org2MSP.member')"

九、查询并发起交易

peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

在另外一个节点查询交易
CORE_PEER_LOCALMSPID="Org2MSP" 
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt 
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp 
CORE_PEER_ADDRESS=peer0.org2.example.com:7051

peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

 

十、查看日志

docker logs -f peer0.org1.example.com
