1. 创建通道配置文件
在有系统通道的情况下搭建应用通道时在启动相关docker容器之前一定要先创建系统通道(应用通道可以等到容器启动之后创建)。所以这里要先创建系统通道配置文件configtx.yaml其具体内容如下

#在finance_network目录下执行
configtxgen -profile TwoOrgsOrdererGenesis -channelID system-channel -outputBlock ./system-genesis-block/genesis.block -configPath ./如果在启动docker容器之前没有创建系统通道的话可能会提示如下错误panic: unable to bootstrap orderer. Error reading genesis block file: read /var/hyperledger/orderer/orderer.genesis.block: is a directory。 出现这种错误是因为在docker配置文件中指定了系统通道文件路径docker容器会自己创建相关文件。
2. 创建docker配置文件
这里创建compose/compose-withsystem.yaml文件作为docker容器配置文件这里要增加系统通道相关的环境变量。文件具体内容如下

#在finance_network目录下执行
sudo DOCKER_SOCK/var/run/docker.sock docker-compose -f compose/compose-withsystem.yaml up -d创建应用通道及配置锚节点
接下来使用如下命令创建应用通道并配置各个组织的锚节点。
#创建应用通道
configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID mychannel
#设置组织Org1的锚节点
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID mychannel -asOrg Org1MSP
#设置组织Org2的锚节点
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID mychannel -asOrg Org2MSP接下来的peer节点加入通道及部署链码等的操作将使用Fabric-sdk-go来实现具体参考博客https://blog.csdn.net/yeshang_lady/article/details/134921528。 Tips:在使用Fabric-SDK-GO进行后续操作的时候要对docker容器进行重启(注意只需要重启docker容器)。因为Fabric-SDK-GO会依据我们生成的文件(channel.tx、Org1MSPanchors.tx、Org2MSPanchors.tx)重新进行创建应用通道及配置锚节点等操作。如果不重启则会提示如下错误 create channel failed: create channel failed: SendEnvelope failed: calling orderer orderer.finance.com:7050 failed: Orderer Server Status Code: (400) BAD_REQUEST. Description: error applying config update to existing channel mychannel: error authorizing update: error validating ReadSet: proposed update requires that key [Group] /Channel/Application be at version 0, but it is currently at version 1
