Fabric 2.2 fabric-samples 3d2875c180c67d9f3b3a166bb15b9c73fb6c7091 fabric-samples 15275a0d4d46696c22e652a0674e36c570431a33
演示证书模板生成
cryptogen showtemplate > crypto-config.yaml
修改crypto-config.yaml
文件中3处有关EnableNodeOUs
的部分为true
。
sed -i 's/EnableNodeOUs: false/EnableNodeOUs: true/g' crypto-config.yaml
根据crypto-config.yaml
生成相关证书
cryptogen generate --config=crypto-config.yaml
这期课程生成组织文件,会生成crypto-config
目录。
创建通道所需的配置,需要选择Sep 16, 2020
的提交
wget https://raw.githubusercontent.com/hyperledger/fabric-samples/3d2875c180c67d9f3b3a166bb15b9c73fb6c7091/test-network/configtx/configtx.yaml -O configtx.yaml
更改msp路径为项目具体的路径。
搜索所有包含../organizations
文本的路径,替换为crypto-config
当前路径。
sed -i 's/..\/organizations/crypto-config/g' configtx.yaml
修改Profiles
中的部分,按照官方文档中的内容来。
所选提交无需修改Profiles
部分。
使用官方工具,生成通道配置。
# 生成创世块文件
configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block -channelID fabric-channel
# 生成通道文件
configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID mychannel
# 生成组织1锚节点文件
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/OrglMSPanchors.tx -channelID mychannel -asOrg Org1MSP
# 生成组织2锚节点文件
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID mychannel -asOrg Org2MSP
在channel-artifacts
中会生成4个文件。
创建peer与排序节点
wget https://raw.githubusercontent.com/hyperledger/fabric-samples/15275a0d4d46696c22e652a0674e36c570431a33/test-network/docker/docker-compose-test-net.yaml -O docker-compose.yaml
修改networks.test.name
为:twonodes_test
。
修改volumes
中对应的宿主机路径。
修改组织1与组织2的网络名称和挂载路径
修改peer0.org2.example.com
环境变量中的CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE
为twonodes_test
。
把cli拆成cli1和cli2,分别表示两个组织的cli,环境变量部分,参考测试网络中的内容进行配置。
热心网友提供的docker-compose.yml
文件
第三期中的docker-compose中还有一处需要修改,有关节点启动方式,详看视频。或者直接拿热心网友的文件过来用。 启动集群
mkdir -p chaincode/go/
docker-compose up -d
docker-compose ps
进入到终端节点
使用cli1创建一个通道mychannel.block
,并加入到该通道。
docker exec -it cli1 bash
peer channel create -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/channel.tx --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/msp/tlscacerts/tlsca.example.com-cert.pem
ls mychannel.block
peer channel join -b mychannel.block
exit
将创建好的通道复制到本地宿主机,将其传入cli2中,并加入到该通道。
docker cp cli1:/opt/gopath/src/github.com/hyperledger/fabric/peer/mychannel.block ./
docker cp ./mychannel.block cli2:/opt/gopath/src/github.com/hyperledger/fabric/peer/mychannel.block
docker exec -it cli2 bash
ls mychannel.block
peer channel join -b mychannel.block
exit
更新锚节点
docker exec -it cli1 bash
peer channel update -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/OrglMSPanchors.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
exit
docker exec -it cli2 bash
peer channel update -o orderer.example.com:7050 -c mychannel -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
exit
关于链码生命周期的操作
# 下载链码
wget https://raw.githubusercontent.com/hyperledger/fabric-samples/3d2875c180c67d9f3b3a166bb15b9c73fb6c7091/chaincode/sacc/sacc.go -O chaincode/go/sacc.go
# 编译链码
docker exec -it cli1 bash
cd /opt/gopath/src/github.com/hyperledger/fabric/examples/chaincode/go
设置goproxy代理:go env -w GOPROXY=https://goproxy.cn,direct
go mod init
go mod tidy
go mod vendor
# 打包链码并分发链码
cd /opt/gopath/src/github.com/hyperledger/fabric/peer
peer lifecycle chaincode package sacc.tar.gz --path /opt/gopath/src/github.com/hyperledger/fabric/examples/chaincode/go/ --label sacc_1
ls sacc.tar.gz
exit
docker cp cli1:/opt/gopath/src/github.com/hyperledger/fabric/peer/sacc.tar.gz ./
docker cp ./sacc.tar.gz cli2:/opt/gopath/src/github.com/hyperledger/fabric/peer/sacc.tar.gz
开启两个终端,分别进入cli1和cli2,执行以下命令。
# 安装链码
peer lifecycle chaincode install sacc.tar.gz

# 查询已安装链码id
peer lifecycle chaincode queryinstalled

链码的整个生命周期完成 链码调用
peer chaincode invoke -o orderer.example.com:7050 --isInit --ordererTLSHostnameOverride orderer.example.com --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n sacc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["a","bb"]}'
链码查询
peer chaincode query -C mychannel -n sacc -c '{"Args":["query","a"]}'
链码测试键值对["a","cc"]
peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n sacc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["set","a","cc"]}'
