一、参考文档

  • hyperledger超级账本官方文档地址：https://hyperledger-fabric.readthedocs.io/en/release-2.2/

  • hyperledger中文文档：https://hyperledgercn.github.io/hyperledgerDocs/

二、环境依赖

  • ubuntu 20.04.1
  • go version go1.16.3 linux/amd64
  • git version 2.25.1
  • docker 20.10.17
  • docker-compose 1.29.2

三、Fabric源码安装

3.1、创建链目录

mkdir -p $GOPATH/src/github.com/hyperledger

3.2、下载源码

cd $GOPATH/src/github.com/hyperledger
git clone https://gitee.com/hyperledger/fabric.git -b v2.2.0

3.3、修改安装脚本

vim $GOPATH/src/github.com/hyperledger/fabric/scripts/bootstrap.sh
  1. 把 https://github.com/hyperledger/fabric-samples.git 修改为 https://gitee.com/hyperledger/fabric-samples.git
  2. 注释 pullBinaries

3.4、开始安装

3.4.1、执行安装脚本

cd $GOPATH/src/github.com/hyperledger/fabric/scripts/
./bootstrap.sh

若报错：

Pull Hyperledger Fabric docker imagesFABRIC_IMAGES: peer orderer ccenv tools nodeenv baseos javaenv
===> Pulling fabric Images
====> hyperledger/fabric-peer:2.2.0
Error response from daemon: error parsing HTTP 408 response body: invalid character '<' looking for beginning of value: "<html><body><h1>408 Request Time-out</h1>\nYour browser didn't send a complete request in time.\n</body></html>\n"
Error response from daemon: No such image: hyperledger/fabric-peer:2.2.0
Error response from daemon: No such image: hyperledger/fabric-peer:2.2.0
====> hyperledger/fabric-orderer:2.2.0

error parsing HTTP 408 response body: invalid character '<' looking for beginning of value: "<html><body><h1>408 Request Time-out</h1>\nYour browser didn't send a complete request in time.\n</body></html>\n"
Error response from daemon: No such image: hyperledger/fabric-orderer:2.2.0
Error response from daemon: No such image: hyperledger/fabric-orderer:2.2.0
====> hyperledger/fabric-ccenv:2.2.0

则尝试调整/etc/docker/daemon.json：

{"registry-mirrors": ["http://hub-mirror.c.163.com","https://registry.docker-cn.com","https://docker.mirrors.ustc.edu.cn"]
}

sudo systemctl daemon-reload
sudo systemctl restart docker

3.4.2、手动下载ca和二进制配置包

下载bootstrap.sh中指定的对应版本ca和二进制配置的包：

# VERSION=2.2.0
wget https://github.com/hyperledger/fabric/releases/download/v2.2.0/hyperledger-fabric-linux-amd64-2.2.0.tar.gz
# CA_VERSION=1.4.7
wget https://github.com/hyperledger/fabric-ca/releases/download/v1.4.7/hyperledger-fabric-ca-linux-amd64-1.4.7.tar.gz

复制到fabric-samples目录：

tar -zxvf hyperledger-fabric-linux-amd64-2.2.0.tar.gz
tar -zxvf hyperledger-fabric-ca-linux-amd64-1.4.7.tar.gz
cp -r bin fabric-samples/
cp -r config fabric-samples/

四、启动测试网络

cd $GOPATH/src/github.com/hyperledger/fabric/scripts/fabric-samples/test-network
# cryptogen启动方式
./network.sh up
# ca-server启动方式
# ./network.sh up -ca

看到docker的2个peer节点容器、1个orderer节点容器和客户端tools容器都正常运行，测试网络启动成功。

五、使用测试网络

5.1、创建应用通道

使用network.sh脚本在org1和org2之间创建通道并加入他们的对等节点，执行以下命令创建一个通道：

./network.sh createChannel -c mychannel

5.2、部署链码

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

5.3、发送交易

配置环境变量：

cd $GOPATH/src/github.com/hyperledger/fabric/scripts/fabric-samples/test-networkexport PATH=${PWD}/../bin:$PATH
# 该目录下包含peer节点的core.yaml
export FABRIC_CFG_PATH=$PWD/../config/# 客户端连接peer0
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

发交易，初始化资产（调用链码的初始化方法InitLedger）：

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":[]}'

查询初始化后的资产（调用链码的GetAllAssets方法）：

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

六、关闭测试网络

./network.sh down
