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
