生成创世区块
configtxgen 命令允许用户创建和查看通道配置相关构件。所生成的构件取决于 configtx.yaml 的内容。
-profile:：对应 configtx.yaml 文件中的 Profiles的配置项
-channelID：通道ID，自己命名
FABRIC_CFG_PATH ：这个路径下一定要有 configtx.yaml 和 crypto-config
configtxgen -profile OrdererGenesis -configPath $FABRIC_CFG_PATH -channelID $sys_channel -outputBlock ./channel-artifacts/genesis.block
执行成功后的结果：
生成通道文件
channelID：通道ID
configtxgen -profile BasicChannel -configPath . -outputCreateChannelTx ../channel-artifacts/mychannel.tx -channelID mychannel
执行结果如下：
生成锚节点
configtxgen -profile BasicChannel -configPath . -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID mychannel -asOrg Org1MSP
configtxgen -profile BasicChannel -configPath . -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID mychannel -asOrg Org2MSP
执行结果如下：
