Hyperledger Fabric1.4 手动搭建过程

1、生成证书：

#路径需要更改为自己的路径
cd ~/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network/  

#在这里可能会报错，通常是权限问题，可以添加sudo重新执行
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.

2、Orderer服务 生成创世区块，通道配置，锚节点配置文件

#路径需要更改为自己的路径
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..）

-profile :configtx.yaml中的Profiles配置项，用于指定生成初始区块还是通道交易配置文件。
-asOrg：用于指定有权设置的写集中的值的Org组织名称。

3、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

4、创建通道

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 指定要创建的应用通道名称
-f 指定创建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

5、将节点加入应用通道

peer channel join -b mychannel.block 

6、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

7、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命令可以安装指定的ChainCode并对其命名：

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

8、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')"

9、查询并发起交易

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

在另一个节点查询交易
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"]}'

10、查看日志

docker logs -f peer0.org1.example.com
