Question

我一直关注此链接：http://hyperledger-fabric.readthedocs.io/en/latest/build_network.html#troubleshoot用于启动我的第一个网络，使用byfn.sh文件，并执行了所有步骤

export CHANNEL_NAME=mychannel  && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME

我得到的错误是：

himani@himani-HP-Notebook:~/fabric-samples/first-network$ export CHANNEL_NAME=mychannelthis  && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME2018-06-07 11:42:00.552 IST [common/tools/configtxgen] main -> INFO 001 Loading configuration

我尝试过命令的变体，

export CHANNEL_NAME=mychannelanother  && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME

export CHANNEL_NAME=mychannelanother  && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $mychannelanother

export CHANNEL_NAME=mychannel  && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $mychannel

我甚至尝试在不使用byfn.sh文件的情况下创建频道，但出现了不同的错误

himani@himani-HP-Notebook:~/fabric-samples/first-network$ peer channel create -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/channel.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

我通过引用修改了 /home/himani/fabric-samples/first-network/crypto-config/ordererOrganizations/example.com/tlsca/tlsca.example.com-cert.pem doc到这个链接：https://gerrit.hyperledger.org/r/#/c/18177/，并再次执行命令，但无济于事。

我的证书是否过时了？我在哪里可以找到合适的？这个问题还有别处吗？

更新在提到类似问题的解决方案Hyperledger Fabric v1.1.0 byfn tutorial on Ubuntu 16.04之后，我关闭了我的网络并试图清理工件，但我无法执行这些命令。 Channel artifacts文件夹为空。

I couldn't execute those commands

Answer 1

此命令用于在channel-artifacts文件夹中添加文件，但由于某种原因，该文件夹未自动创建。在创建一个具有足够权限的情况下，创建了执行的命令和创建块。

Answer 2

我不知道您是否解决了问题，但是那里有些错误。

如果您正在学习本教程，则CHANNEL_NAME应该为mychannel。

对于第三个版本，应该是这样

export CHANNEL_NAME=mychannel  && ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME

对于创建通道，对等通道创建只能在docker容器内发送。如果您是直接从命令行发送的，请尝试

docker exec -it yourCliContainerName peer channel create -o orderer.example.com:7050 -c mychannelthis -f ./channel-artifacts/channel.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

但请记住先启动容器。

希望这会有所帮助
