HyperLedger Fabric - 超级账本（5）使用多通道

使用多通道

$ cd ~/hyfa/fabric-samples/chaincode-docker-devmode

$ sudo docker-compose -f docker-compose-simple.yaml down   

$ cd ../first-network

创建一个应用通道的配置交易

务必替换$CHANNEL_NAME或设置CHANNEL_NAME为可在整个说明中使用的环境变量

$ export CHANNEL_NAME=mychannel2 

指定使用 configtx.yaml 配置文件中的 TwoOrgsChannel 模板, 来生成新建通道的配置交易文件,

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

输出如下

11:13:24.984 CST [common/tools/configtxgen] main -> INFO 001 Loading configuration
11:13:24.992 CST [common/tools/configtxgen] doOutputChannelCreateTx -> INFO 002 Generating new channel configtx
11:13:24.993 CST [msp] getMspConfig -> INFO 003 Loading NodeOUs
11:13:24.994 CST [msp] getMspConfig -> INFO 004 Loading NodeOUs
11:13:25.016 CST [common/tools/configtxgen] doOutputChannelCreateTx -> INFO 005 Writing new channel tx

生成锚节点配置更新文件

锚节点配置更新文件用来对组织的锚节点进行配置

同样基于 configtx.yaml 配置文件生成新建通道文件, 每个组织都需要分别生成且注意指定对应的组织名称

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

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

启动网络

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

进入Docker容器

执行如下命令进入到CLI容器中

$ sudo docker exec -it cli bash

创建通道

检查环境变量是否正确设置

echo $CHANNEL_NAME

设置环境变量

export CHANNEL_NAME=mychannel2

创建通道

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

加入通道

应用通道所包含组织的成员节点可以加入通道中

peer channel join -b mychannel2.block -o orderer:7050

---

更新锚点

使用Org1的管理员身份更新锚节点配置

peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org1MSPanchors.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

使用Org2的管理员身份更新锚节点配置

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 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 peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org2MSPanchors.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

列出所加入的通道

peer channel list

list命令会列出指定的Peer节点已经加入的所有应用通道的列表.
