How to run "configtxgen" command to build the orderer genesis block for BYFN (Build Your First Network)?

You can follow this tutorial to run "configtxgen" command to build Orderer Genesis Block for BYFN.

The "configtxgen" command file is located in the ../bin directory. It takes the configtx.yaml file as the input with the help of FABRIC_CFG_PATH environment variable:

$ cd hyperledger-binaries/fabric-samples/first-network

$ export FABRIC_CFG_PATH=./
$ mkdir ./channel-artifacts
$ ../bin/configtxgen -profile TwoOrgsOrdererGenesis -channelID byfn-sys-channel \
   -outputBlock ./channel-artifacts/genesis.block

...[common.tools.configtxgen] main -> INFO 001 Loading configuration
...[common.tools.configtxgen.localconfig] completeInitialization \
   -> INFO 002 orderer type: solo
...[common.tools.configtxgen.localconfig] Load -> INFO 003 Loaded configuration: \
   /home/fyicenter/hyperledger-binaries/fabric-samples/first-network/configtx.yaml
...[common.tools.configtxgen.localconfig] completeInitialization \
   -> INFO 004 orderer type: solo
...[common.tools.configtxgen.localconfig] LoadTopLevel -> INFO 005 Loaded configuration: \

...[common.tools.configtxgen] doOutputBlock -> INFO 006 Generating genesis block
...[common.tools.configtxgen] doOutputBlock -> INFO 007 Writing genesis block

The orderer genesis block is generated in the ./channel-artifacts sub-directory and named as "genesis.block":

$ ls -l ./channel-artifacts
