错误一
Missing channelID, please specify it with ‘-channelID’
解决方法：
export CHANNEL_NAME=mychannel
/home/aka/go/bin/configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block -channelID $CHANNEL_NAME
错误二
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
报错
Error: failed to create deliver client for orderer: orderer client failed to connect to orderer.example.com:7050: failed to create new connection: connection error: desc = “transport: error while dialing: dial tcp 127.0.0.1:7050: connect: connection refused”
然后查看orderer容器，发现orderer容器exit
查看了docker日志，
docker logs orderer.example.com
找到做错误：
Not bootstrapping because of 2 existing channels
由于 2 个现有通道而无法引导
可能是数据卷映射的问题，然后查看了docker volume的内容
docker volume ls
将orderer本地映射的数据卷删除
docker volume rm -f fixtures_orderer.example.com
重新启动docker-compose.yaml
