I installed hyperledger fabric v1.1.0-rc1 using byfn.sh.

(Reference: http://hyperledger-fabric.readthedocs.io/en/lastest/build_network.html)

But I got some failure. It's Fabric CA problem?

[executed]

./byfn.sh -m generate

./byfn.sh -m up

../bin/cryptogen generate --config=./crypto-config.yaml

export FABRIC_CFG_PATH=$PWD

../bin/configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

export CHANNEL_NAME=mychannel

./bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME

my configtx.yaml is https://github.com/hyperledger/fabric-samples/blob/release-1.1/first-network/configtx.yaml

回答1:

I faced a similar issue. What helped me was to start over.

• Bring down the network: ./byfn.sh -m down
• Clean up the generated artifacts
  • rm crypto-config
  • rm channel-artifacts

Then issue again the commands. This helped me, the channel.tx and other were successfully created. No need to change the configtx.yaml from the sample.

You don't have to delete files you just need to make sure that ./byfn.sh -m down was executed prior to steps in Crypto Generator section
