2. 创建Channel

参考：创建一个新的channel

创建通道：

运行下面的程序来为coreandfirstchannel通道创建一个“创建通道的交易”

1
configtxgen -profile CoreAndFirstChannel -outputCreateChannelTx ./channel-artifacts/coreandfirstchannel.tx -channelID coreandfirstchannel

执行结果如下：

2020-12-24 14:29:40.750 CST [common.tools.configtxgen] doOutputChannelCreateTx -> INFO 004 Writing new channel tx

设置环境变量，以核心企业(core.supply.com)管理员身份操作peerCLI;然后使用下面的命令把交易发给order服务创建通道：

1
peer channel create -o localhost:8050  --ordererTLSHostnameOverride orderer.supply.com -c coreandfirstchannel -f ./channel-artifacts/coreandfirstchannel.tx --outputBlock ./channel-artifacts/coreandfirstchannel.block --tls --cafile ${PWD}/organizations/ordererOrganizations/supply.com/orderers/orderer.supply.com/msp/tlscacerts/tlsca.supply.com-cert.pem

正确执行之后的日志：

错误原因：peer channel create -o localhost:8051 命令-o应该传入order服务的地址和端口。

把核心企业和一级供应商的peer加入通道

核心企业的peer加入通道

使用下面的命令将核心企业的peer加入通道（确认已经设置了核心企业的环境变量）：

1
peer channel join -b ./channel-artifacts/coreandfirstchannel.block

成功信息如下：

Error: error getting endorser client for channel: endorser client failed to connect to localhost:8051: failed to create new connection: context deadline exceeded

**错误原因：**未知。

**解决方式：**把Profiles里面的Organizations信息统一修改，与环境变量保持一致

Organizations:
    - *GylCoreOrg1MSP
    - *GylFOrg1MSP
    - *GylSOrg1MSP
    - *GylSOrg2MSP

然后把上面步骤中生成的加密材料信息、区块信息都删除，容器和volume全部删除；重新执行一遍。

通过获取通道信息确认加入成功

获取通道信息

1
peer channel getinfo -c coreandfirstchannel

可以看到如下信息：

2020-12-24 16:53:01.633 CST [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
Blockchain info: {"height":1,"currentBlockHash":"kXOOwW8prt0XPvgEGMDrzdt1nNH8T7qlObL9eT8FZ7c="}

一级供应商加入通道

设置环境变量，然后拉取通道的创世纪区块(因为是测试本次忽略)：

1
peer channel fetch 0 ./channel-artifacts/coreandfirstchannel.block -o localhost:8050  --ordererTLSHostnameOverride orderer.supply.com -c coreandfirstchannel --tls --cafile ${PWD}/organizations/ordererOrganizations/supply.com/orderers/orderer.supply.com/msp/tlscacerts/tlsca.supply.com-cert.pem

加入通道：

1
peer channel join -b ./channel-artifacts/coreandfirstchannel.block

成功信息如下：

**错误原因：**因为在设置环境变量时不是在supply-finance目录下设置的，所以设置的环境变量有问题，重新设置一下。

设置锚节点

为GylFOrg1MSP设置锚节点

因为上面已经设置了一级供应商（GylFOrg1MSP）的环境变量，所以先设置GylFOrg1MSP的锚节点：

拉取最新的channel配置区块
1
peer channel fetch config channel-artifacts/coreandfirstchannel_config_block.pb -o localhost:8050 --ordererTLSHostnameOverride orderer.supply.com -c coreandfirstchannel --tls --cafile ${PWD}/organizations/ordererOrganizations/supply.com/orderers/orderer.supply.com/msp/tlscacerts/tlsca.supply.com-cert.pem

修改通道配置区块

切换到channel-artifacts然后把区块内容转换成json格式：

1

cd channel-artifacts
configtxlator proto_decode --input coreandfirstchannel_config_block.pb --type common.Block --output coreandfirstchannel_config_block.json
jq .data.data[0].payload.data.config coreandfirstchannel_config_block.json > coreandfirstchannel_config.json
# copy一份
cp coreandfirstchannel_config.json coreandfirstchannel_config_copy.json

使用jq 工具来添加GylFOrg1MSP组织的锚节点到通道配置。

1
jq '.channel_group.groups.Application.groups.GylFOrg1MSP.values += {"AnchorPeers":{"mod_policy": "Admins","value":{"anchor_peers": [{"host": "peer0.f1.supply.com","port": 8053}]},"version": "0"}}' coreandfirstchannel_config_copy.json > modified_coreandfirstchannel_config.json

将原始的和修改后的通道配置都转换回protobuf格式，并计算它们之间的差异。

configtxlator proto_encode --input coreandfirstchannel_config.json --type common.Config --output coreandfirstchannel_config.pb

configtxlator compute_update --channel_id coreandfirstchannel --original coreandfirstchannel_config.pb --updated modified_coreandfirstchannel_config.pb --output coreandfirstchannel_config_update.pb
把更新后的交易打包成一个更新通道配置的交易：

configtxlator proto_decode --input coreandfirstchannel_config_update.pb --type common.ConfigUpdate --output coreandfirstchannel_config_update.json
echo '{"payload":{"header":{"channel_header":{"channel_id":"coreandfirstchannel", "type":2}},"data":{"config_update":'$(cat coreandfirstchannel_config_update.json)'}}}' | jq . > coreandfirstchannel_config_update_in_envelope.json
configtxlator proto_encode --input coreandfirstchannel_config_update_in_envelope.json --type common.Envelope --output coreandfirstchannel_config_update_in_envelope.pb
提交“更新通道配置的交易”

进到上一级目录cd ..，之后运行命令将交易提交给排序服务进行通道配置的更新：

1
2
cd ..
peer channel update -f channel-artifacts/coreandfirstchannel_config_update_in_envelope.pb -c coreandfirstchannel -o localhost:8050  --ordererTLSHostnameOverride orderer.supply.com --tls --cafile ${PWD}/organizations/ordererOrganizations/supply.com/orderers/orderer.supply.com/msp/tlscacerts/tlsca.supply.com-cert.pem

部署测试chaincode来确认

打包

1
peer lifecycle chaincode package basic.tar.gz --path /Users/apple/code/open-source/blockchain/hyperledger/fabric-samples/asset-transfer-basic/chaincode-go/ --lang golang --label basic_1.0

运行完上面的命令，查看当前目录会发现多了basic.tar.gz包，说明打包成功。

安装链码包

一级供应商和核心企业都要安装：
核心企业：

1
peer lifecycle chaincode install basic.tar.gz --peerAddresses localhost:8051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/core.supply.com/peers/peer0.core.supply.com/tls/ca.crt

一级供应商：

1
peer lifecycle chaincode install basic.tar.gz --peerAddresses localhost:8053 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/f1.supply.com/peers/peer0.f1.supply.com/tls/ca.crt

/supply-finance$     docker start bc47970e58a5
Error response from daemon: network _test not found
Error: failed to start containers: bc47970e58a5

问题解决：

因为在docker-compose.yml文件中配置了下面的环境变量，在启动chaincode容器时会链接到这个网络。

之前的配置是：

1
- CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=${COMPOSE_PROJECT_NAME}_test

修改后重新启动，问题解决。

1
- CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=docker_test

为什么修改成docker_test呢，可以查看使用docker-compose命令启动容器时的日志：

Creating network "docker_test" with the default driver

核心企业、一级和二级供应商加入同一个channel

创建通道：

运行下面的程序来为alljoinchannel通道创建一个“创建通道的交易”

3
configtxgen -profile AllPlayChannel -outputCreateChannelTx ./channel-artifacts/alljoinchannel.tx -channelID alljoinchannel
# 使用下面的命令把交易发给order服务创建通道：
peer channel create -o localhost:8050  --ordererTLSHostnameOverride orderer.supply.com -c alljoinchannel -f ./channel-artifacts/alljoinchannel.tx --outputBlock ./channel-artifacts/alljoinchannel.block --tls --cafile ${PWD}/organizations/ordererOrganizations/supply.com/orderers/orderer.supply.com/msp/tlscacerts/tlsca.supply.com-cert.pem

加入通道

使用下面的命令将peer加入通道,所有节点都需要执行：

1

3
peer channel join -b ./channel-artifacts/alljoinchannel.block
# 通过获取通道信息确认加入成功
peer channel getinfo -c alljoinchannel
