ubuntu环境下安装hyperledger fabric

docker安装

使用阿里云镜像通过官方脚本自动安装，可以先去修改软件源，用国内的源速度更快

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

检验docker的安装

docker -v

显示当前安装的版本，安装成功

docker-compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

修改为可执行模式

sudo chmod +x /usr/local/bin/docker-compose

检验方法类似

docker-compose -v

go语言安装

详情见我的另一篇文章
ubuntu18.04下搭建golang环境

安装fabric

这里条件允许的话建议挂vpn，用官方提供的脚本安装，不容易出问题

curl -sSL https://bit.ly/2ysbOFE | bash -s

脚本会自动下载fabric的二进制文件和docker镜像，完成后出现fabric-samples文件夹

安装测试 测试前的准备

在测试前需要安装一个go语言的依赖包
先把golang的代理地址切换成国内地址

go env -w GOPROXY="https://goproxy.cn,direct"

在fabric-samples下进入go语言链码目录

cd asset-transfer-basic/chaincode-go

安装vendor

go mod vendor

启动测试网络

进入到fabric测试用例

cd ../test-network

运行测试网络脚本

./network.sh up

日志显示各节点创建成功，docker镜像也成功启动

创建通道

./network.sh createChannel

通道创建成功后，会显示Org1和Org2的锚节点anchor peer都加入了创建的通道“mychannel”

安装链码

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

与联盟链进行交互

先引入相关的环境变量

export PATH=${PWD}/../bin:$PATH
export FABRIC_CFG_PATH=$PWD/../config/

引入Org1的环境变量

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

初始化账本资产

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":[]}'

显示设置成功

查询

peer chaincode query -C mychannel -n basic -c '{"Args":["GetAllAssets"]}'

返回查询结果

调用资产转移链码来转移链上的资产

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"]}'

同样，后续可以通过引入Org2的环境变量，从Org2的节点进行查询和链码调用 *** 作

export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
export CORE_PEER_ADDRESS=localhost:9051

关闭网络

*** 作结束后切记及时关闭网络，否则后续再次 *** 作时，会因docker镜像没有关闭报错

./network.sh down
