一 Fabric-X86

1.查看虚拟机环境 

uname -a

显示X86架构 centos7发行版本

在这里插入图片描述

2.源码克隆

选定位置进行GitHub代码克隆，命令为 

git clone https://github.com/hyperledger/fabric.git

在这里插入图片描述

克隆成功后生成文件夹fabric，源码克隆成功

在fabric目录切换版本至V2.2.5 

cd fabric
git checkout v2.2.5

3.golang版本升级

根据要求部署fabric2.2.5版本，go的版本需要最低达到1.14.1版本

下载安装包 

wget https://storage.googleapis.com/golang/go1.19.3.linux-amd64.tar.gz

解压至固定位置 

tar -xvf go1.19.3.linux-amd64.tar.gz -C /usr/local/

配置环境变量 

vi /etc/profile

末尾添加 

export GOROOT=/usr/local/go
export GOPATH=/root/go
export PATH=$PATH:/usr/local/go/bin

刷新环境变量： 

source /etc/profile

查看go版本信息 

go version

4.拉取fabric镜像

进入 /fabric/scripts 目录 

cd fabric/scripts/

修改 bootstrap.sh 脚本 

vi bootstrap.sh

在这里插入图片描述

修改完毕后运行脚本拉取镜像 

 ./bootstrap.sh

查看拉取的镜像 

docker images

5.启动测试网络

将 bin 和 config 复制到 fabric-samples 目录下： 

[root@localhost ~]# cp -r bin/ fabric-samples/
[root@localhost ~]# cp -r config/ fabric-samples/

将 fabric-samples 的 bin 加入路径PATH： 

vi /etc/profile
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin:/root/fabric-samples/bin
source /etc/profile

到test-network目录下运行启动脚本 

./network.sh up

在这里插入图片描述

Fabric测试网络启动成功

关闭测试网络

./network.sh down

6.将智能合约部署到通道

创建通道 

./network.sh up createChannel

该命令创建一个以两个通道成员 Org1 和 Org2 命名的通道

在这里插入图片描述

使用Java链码，打包智能合约

进入Java文件夹 

cd fabric-samples/chaincode/fabcar/java

安装智能合约依赖项 

./gradlew installDist

在这里插入图片描述

命令成功，能够在文件夹中找到构建的智能合约

使用 CLI 创建所需格式的链码包 

cd ../../../test-network

二进制文件添加到 CLI 路径 

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

检查二进制文件的版本 

peer version

在这里插入图片描述

创建链码包 

peer  lifecycle  chaincode  package fabcar.tar.gz --path ../chaincode/fabcar/java/build/
install/fabcar --lang java --label fabcar_1

安装链码包

在 Org1 上安装链码，设置以下环境变量以 Org1 管理员用户身份操作 CLI 

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

在 Peer节点上安装链码 

peer lifecycle chaincode install fabcar.tar.gz

在这里插入图片描述

在 Org2 上安装链码，以下环境变量设置以Org2为管理员和目标 

export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_TLS_ROOTCERT_FILE=${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

安装链码 

peer lifecycle chaincode install fabcar.tar.gz

在这里插入图片描述

批准链码定义 

peer lifecycle chaincode queryinstalled

返回包id，在下一步骤需要使用

在这里插入图片描述

使用包id，设置环境变量 

export CC_PACKAGE_ID=fabcar_1:cf8172d318266bd1e58a4112c32340b14c1fbf4d787824c4f312dae9a701bc0d

分发给其他节点 

peer  lifecycle  chaincode  approveformyorg -o  localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name fabcar --version 1.0 --package-id $CC_PACKAGE_ID --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

在这里插入图片描述

设置以下环境变量以 Org1 管理员身份运行 

export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/
org1.example.com/users/Admin@org1.example.com/msp
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/
peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_ADDRESS=localhost:7051

批准链码定义为 Org1 

peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverrideorderer.example.com --channelID mychannel --name fabcar --version 1.0 --package-id $CC_PACKAGE_ID --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

在这里插入图片描述

将链码定义提交到通道 

peer lifecycle  chaincode  checkcommitreadiness--channelID mychannel --name fabcar --version 1.0 --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --output json

在这里插入图片描述

提交命令将链码定义提交到通道 

peer lifecycle chaincode commit -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name fabcar --version 1.0 --sequence 1 --tls --cafile${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --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

在这里插入图片描述

通过查询提交命令来确认链码定义已提交到通道 

peer lifecycle chaincode querycommitted --channelID mychannel --name fabcar --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

返回链码定义的序列和版本

调用链码 

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 fabcar --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":[]}'
