完成 Fabric 1.4 环境搭建后，可以调用 first-network 的 byfn.sh 程序来验证是否环境搭建成功。该shell脚本实际上就是搭建了4个peer节点，1个order，1个cli的组网，之后通过链码的安装，实例化和调用来验证环境是否搭建成功。但我们已经对其中的配置和流程较为模糊。为此，我们仿照byfn脚本的内容完成了手动的全流程实现，对配置和组网细节进行深入了解，便于之后的学习使用。
- 将 Fabric 二进制工具放到环境变量中，用于之后生成文件使用
# 将工具放入环境变量
export PATH=/opt/go-project/src/github.com/hyperledger/fabric/scripts/fabric-samples/bin:$PATH
# 创建开发目录
cd /opt/go-project/src/github.com/hyperledger/fabric/scripts/fabric-samples
mkdir my-network
cd my-network

- 配置
crypto-config.yaml文件，利用cryptogen得到证书文件
# 拷贝crypto-config.yaml的配置文件
cp ../first-network/crypto-config.yaml .
# 利用配置文件生成相关的证书文件
cryptogen generate --config=./crypto-config.yaml
image-20221207200447106.png
- 配置
configtx.yaml文件，利用configtxgen生成创世块文件、通道和锚节点
# 拷贝configtx.yaml的配置文件
cp ../first-network/configtx.yaml .
# 用于后续映射文件操作
mkdir channel-artifacts
mkdir chaincode
# 生成创始块文件
configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block
# 生成通道文件 -channelID通道名字 默认为 mychannel
export CHANNEL_NAME=mychannel
configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME
# 生成锚节点更新文件
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP

- 配置
docker-compose-cli.yaml文件，用于启动主机
# 拷贝docker-compose-cli.yaml及其依赖的配置文件
cp -r ../first-network/base/ .
cp ../first-network/docker-compose-cli.yaml .
# 设置docker镜像版本和工程名称
export IMAGE_TAG=latest
export COMPOSE_PROJECT_NAME=net
# docker-compose up -d
docker-compose -f docker-compose-cli.yaml up -d
# 查看是否启动成功
docker-compose -f docker-compose-cli.yaml ps
# 关闭容器
# docker-compose -f docker-compose-cli.yaml down -v
image-20221207204019314.png
- 进入cli容器
# 进入客户端操作
docker exec -it cli bash
- 在cli容器中创建通道
export CHANNEL_NAME=mychannel
export ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
# 创建通道
# -o 指定Orderer节点地址:端口
# -c 指定要创建的应用通道名称
# -f 指定创建应用通道时所使用的应用通道交易配置文件
# --tls 开启tls验证
# --cafile orderer节点pem格式的证书文件(绝对路径)
peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls true --cafile $ORDERER_CA
- 将每个peer节点分别加入通道

至此，完成了Fabric 初始测试程序byfn的手动实现。
