ubuntu20.04搭建Fabric教程

news2024/10/7 2:30:54

本章节环境配置

ubuntu: 20.04
go：1.16.3
docker: 20.10.6
docker-compose: 1.27.2
fabric：2.2.0
fabric-ca: 1.4.9

一搭建通道

新建工作目录

mkdir fabric && cd fabric

配置go代理

go env -w GO111MODULE=on

#更新下载包的镜像
go env -w GOPROXY=https://goproxy.cn,direct
go env -w GOPRIVATE=.gitlab.com,.gitee.com
go env -w GOSUMDB="sum.golang.google.cn"

这里我提供了基本环境搭建的脚本

git clone https://gitee.com/mrwhite123/bootstrap.git

#可能会有点慢，稍等即可
bash bootstrap.sh

确保docker已经开启

#开启docker服务
systemctl start docker

#重启服务
systemctl restart  docker

拉取docker镜像

#这里我也提供了脚本，拉取运行即可
git clone https://gitee.com/mrwhite123/shell.git

#可能会有点慢，稍等即可
bash shell/shell.sh

使用如下命令测试镜像是否安装完毕：

docker images

使用测试网络

#进入到test-network目录
cd fabric-samples/test-network

#运行如下命令，以从任何先前运行中删除任何容器或工件：
#若是第一次运行，则同时下载缺少的依赖
./network.sh down

#通过发出以下命令来启动网络。
./network.sh up

#启动后，可以使用如下命令进行查看组成部分：
docker ps -a

创建通道

./network.sh createChannel

在通道上安装链码(部署合约)

./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go

网络进行交互，先配置环境变量，注意，此命令要在test-network目录下使用

export PATH=${PWD}/../bin:$PATH
export FABRIC_CFG_PATH=$PWD/../config/
//配置ORG1的相关设置
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
export CORE_PEER_ADDRESS=localhost:7051

调用链码，初始化脚本

peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n basic --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"function":"InitLedger","Args":[]}'

调用链码，获取资产列表

eer chaincode query -C mychannel -n basic -c '{"Args":["GetAllAssets"]}'
[{"ID":"asset1","color":"blue","size":5,"owner":"Tomoko","appraisedValue":300},{"ID":"asset2","color":"red","size":5,"ow

调用链码，改变账本上的资产所有者

peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n basic --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"function":"TransferAsset","Args":["asset6","Christopher"]}'
