从0搭建Hyperledger Fabric2.5环境

Hyperledger Fabric 2.5环境搭建

一.Linux环境准备

# root登录
yum -y install git curl docker docker-compose tree
yum -y install autoconf autotools-dev automake m4 perl
yum -y install libtool
autoreconf -ivf
# 安装jq相关包
cd /opt
git clone --recursive https://github.com/jqlang/jq.git
cd jq
autoreconf -i
./configure --disable-maintainer-mode
make
make install

# 强制删除之前的镜像
docker rmi --force $(docker images -q)

# 创建用户，设置密码
useradd fabric
passwd fabric
# 添加sudo权限
vi /etc/sudoers
# 在wheel下添加fabric配置
## Same thing without a password
# %wheel        ALL=(ALL)       NOPASSWD: ALL
fabric          ALL=(ALL)       NOPASSWD: ALL
# :wq保存
# 验证是否配置成功
[root@localhost ~]# visudo -cf /etc/sudoers
/etc/sudoers：解析正确

# 切换fabric用户
su - fabric

# 安装过后检查版本
docker --version
docker-compose --version
# docker后台运行
sudo systemctl start docker
# 开机自启
sudo systemctl enable docker
# 用户添加到组
sudo usermod -a -G docker fabric

# 安装go
cd /home/fabric
wget https://golang.google.cn/dl/go1.20.5.linux-amd64.tar.gz
mkdir godir
tar -zxvf go1.20.5.linux-amd64.tar.gz -C ./godir
# 配置环境变量
sudo vi /etc/profile
#golang env config,1.18版本之后无需export GO111MODULE=on,可不设置gopath
export GOROOT=/home/fabric/godir/go
export PATH=$PATH:$GOROOT/bin
export GOPROXY=https://goproxy.cn

source /etc/profile
# 设置代理或者
# go env -w GOPROXY=https://goproxy.cn,direct

二.安装Fabric 、Fabric Samples

• 克隆超级账本/结构样本存储库。
• 下载最新的Hyperledger Fabric Docker镜像并将其标记为latest
• 将以下特定于平台的超级账本 Fabric CLI 工具二进制文件和配置文件下载到fabric-samples /bin 和 /config目录中。

这些二进制文件将帮助您与测试网络进行交互。fabric-samples/bin/config

configtxgen,
configtxlator,
cryptogen,
discover,
idemixgen,
orderer,
osnadmin,
peer,
fabric-ca-client,
fabric-ca-server

下载示例、Docker镜像和二进制文件

su - fabric
# 创建目录
mkdir -p $HOME/go/src/github.com/myproject
cd $HOME/go/src/github.com/myproject
# 获取安装脚本
curl -sSLO https://raw.githubusercontent.com/hyperledger/fabric/main/scripts/install-fabric.sh && chmod +x install-fabric.sh
# 查看帮助
./install-fabric.sh -h

选择组件

• docker以使用 Docker 下载结构容器镜像
• podman使用 podman 下载结构容器镜像
• binary下载结构二进制文件
• samples将构造示例 GitHub 存储库克隆到当前目录

# 下载之前修改脚本，添加github代理
#在download附近的https，前面加上https://ghproxy.com/
download "${BINARY_FILE}" "https://github.com/hyperledger/fabric/releases/download/v${VERSION}/${BINARY_FILE}"
修改为
download "${BINARY_FILE}" "https://ghproxy.com/https://github.com/hyperledger/fabric/releases/download/v${VERSION}/${BINARY_FILE}"

download "${CA_BINARY_FILE}" "https://github.com/hyperledger/fabric-ca/releases/download/v${CA_VERSION}/${CA_BINARY_FILE}"
修改为
download "${CA_BINARY_FILE}" "https://ghproxy.com/https://github.com/hyperledger/fabric-ca/releases/download/v${CA_VERSION}/${CA_BINARY_FILE}"

# 执行安装，当前默认fabric 2.5.0, fabric-ca 1.5.6
./install-fabric.sh docker samples binary
or
./install-fabric.sh d s b

# 若需要选择fabric版本，则执行如下
# --fabric-version -ca-version 简写分别为-f -c,此处默认ca 1.5.6版本
# ./install-fabric.sh --fabric-version 2.5.0 binary

三.运行测试网络(test network)

启动test network

启动网络，创建一个orderer 两个peer,此时不含通道

cd fabric-samples/test-network
# 删除之前运行的容器或项目
./network.sh down
# 清理容器
docker ps -qa | xargs docker rm
# 启动网络，创建一个orderer 两个peer,此时不含通道
./network.sh up

# 查看test-network运行的容器
docker ps -a

与Fabric 网络交互的每个节点和用户都需要属于 组织，以便参与网络。测试内容 网络包括两个对等组织，即组织1 和组织 2。它还包括一个维护网络排序服务的排序者组织。

Peers 节点存储区块链分类账并在交易之前验证交易 提交到账本。Peers运行包含业务的智能合约 用于管理区块链账本上的资产的逻辑。

网络中的每个peer都需要属于一个组织。在test network中每个组织各自运行一个peer，如peer0.org1.example.com，peer0.org2.example.com

每个Fabric网络还包括一个ordering service (排序服务)。 当peer验证事务并将事务块添加到 区块链分类账，他们不决定交易顺序或包括 他们进入新的块。在分布式网络上，peer可能彼此相距很远，并且对事务何时创建没有共同的看法。就交易顺序达成共识是一个成本高昂的过程，会给peer带来很高的开销。

ordering service (排序服务)允许peer专注于验证交易和 将它们提交到账本。排序节点从客户端收到背书交易后，他们就交易顺序达成共识，然后添加交易信息到区块中。然后将区块分发到peer节点，peer节点将区块添加到区块链分类账本中。

示例网络使用由orderer组织运营的单节点Raft ordering service (orderer.example.com)。
测试网络：单节点排序服务
生产环境：多个排序节点，一个或多个orderer 组织。
不同的排序节点将使用 Raft 共识算法就网络上的交易顺序达成一致。

四.创建通道channel

在 Org1和Org2之间交易创建Fabric通道。通道是特定网络成员之间的专用通信层。 通道只能由受邀加入通道的组织使用，并且对网络的其他成员不可见。每个通道都有一个单独的区块链分类账。已被邀请的组织将其peers加入通道，以存储通道分类账并验证通道上的交易。

# 创建默认通道 mychannel
./network.sh createChannel
# 自定义通道名称
#./network.sh createChannel -c channel1
# 创建多个通道，上述创建完成后，还可以创建通道
./network.sh createChannel -c channel2

# 若需要创建通道和启动网络，则可执行
# ./network.sh up createChannel

创建通道日志

[fabric@localhost test-network]$ ./network.sh createChannel

通道名称注意事项

1. 仅包含小写 ASCII 字母数字、点 ‘.’ 和短划线 ‘-’
2. 少于 250 个字符
3. 以字母开头

五.在通道上启动链码

通道之间分类账通过智能合约进行交互。

1. 智能合约包含业务逻辑管理区块链分类账上的资产。网络成员运行的应用程序调用智能合约在分类账上创建资产、更改和转移这些资产。应用程序可查询智能合约以读取账本上的数据。

2. 为了确保交易有效，使用智能合约创建的交易通常需要由多个组织签名才能提交到通道分类账。多重签名是 Fabric 信任模型不可或缺的一部分。要求对一笔交易进行多次背书可以防止渠道上的一个组织篡改其peer的分类账或使用未经同意的业务逻辑。要签署交易，每个组织都需要在其peer上调用并执行智能合约，然后对交易输出进行签名。如果输出是一致的，并且已经由足够多的组织签名，则可以将交易提交到分类账。指定通道上需要执行智能合约的集合组织的策略被称为背书策略，该策略是为每个链代码设置的，作为链代码定义的一部分。

3. 在 Fabric 中，智能合约以称为链码。链码安装在组织的peer节点上，然后部署到通道中，可用于背书交易和与区块链分类账交互。在将链码部署到通道之前，通道的成员需要就建立链码治理的链码定义达成一致。当所需数量的组织达成一致时，可以将链码定义提交到通道，链码则可以使用。

在通道上启动链码

# 使用network.sh创建通道后，可以使用以下命令在通道上启动链代码：

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

deployCC 子命令将在peer0.org1.example.com和peer0.org2.example.com安装asset-transfer (basic)链码，在使用通道标志指定的通道上部署链码（默认mychannel）。第一次部署链码，将安装链码相关依赖。使用语言标志-ccl，可以指定安装Go、Typescript或 JavaScript 链码。 您可以在fabric-samples的asset-transfer-basic文件夹中找到asset-transfer (basic)链码。此文件夹包含作为示例提供的示例链码和教程。

六. 与网络交互

使用peer的CLI进行网络交互，peer CLI调用已部署的智能合约，更新通道或安装、部署新的智能合约。

环境变量设置

cd fabric-samples/test-network
# 确保能使用fabric-samples二进制文件
export PATH=${
    
    PWD}/../bin:$PATH
# 如configtxgen  configtxlator  cryptogen  discover  fabric-ca-client  fabric-ca-server  ledgerutil  orderer  osnadmin  peer

# 设置FABRIC_CFG_PATH指向fabric-samples中的core.yaml的文件
export FABRIC_CFG_PATH=$PWD/../config/
ls $FABRIC_CFG_PATH

设置Org1的peer使用CLI的环境变量

# Environment variables for Org1

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/[email protected]/msp
export CORE_PEER_ADDRESS=localhost:7051

CORE_PEER_TLS_ROOTCERT_FILE和CORE_PEER_MSPCONFIGPATH环境变量指向organizations文件夹中的Org1加密材料。

初始化账本

使用资产初始化账本，CLI 不访问Fabric Gateway peer，因此必须指定每个认可的peer。

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":[]}'

查询账本

从 CLI 查询账本，查询已添加到通道账本的资产列表。

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

查询结果

[{
    
    "AppraisedValue":300,"Color":"blue","ID":"asset1","Owner":"Tomoko","Size":5},{
    
    "AppraisedValue":400,"Color":"red","ID":"asset2","Owner":"Brad","Size":5},{
    
    "AppraisedValue":500,"Color":"green","ID":"asset3","Owner":"Jin Soo","Size":10},{
    
    "AppraisedValue":600,"Color":"yellow","ID":"asset4","Owner":"Max","Size":10},{
    
    "AppraisedValue":700,"Color":"black","ID":"asset5","Owner":"Adriana","Size":15},{
    
    "AppraisedValue":800,"Color":"white","ID":"asset6","Owner":"Michel","Size":15}]

资产转移

网络成员调用链码转移或更改账本上的资产。使用以下命令通过调用资产转移（基本）链码来更改账本上资产的所有者：

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"]}'

因为资产转移（基本）链码的背书策略交易需要要由Org1和 Org2 签名，链码调用命令需要peer0.org1.example.com和peer0.org2.example.com使用–peerAddresses标记。网络启用了 TLS，因此该命令还需要–tlsRootCertFiles标志使用每个peer的 TLS 证书。

查询账本

在我们调用链码之后，我们可以使用另一个查询来查看调用如何 更改了区块链分类账上的资产。由于我们已经查询了 Org1 peer，我们可以查询 Org2 peer上运行的链码。将以下环境变量设置为作为 Org2 运行：

# Environment variables for Org2
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/[email protected]/msp
export CORE_PEER_ADDRESS=localhost:9051

##在peer0.org2.example.com上查询asset-transfer (basic)链码
peer chaincode query -C mychannel -n basic -c '{"Args":["ReadAsset","asset6"]}'

七.关闭网络

该命令将停止并删除节点和链码容器，删除 组织加密材料，并从您的 Docker 注册表中删除链码镜像。该命令还会从以前的运行中删除通道和 docker卷 。

./network.sh down

八.目录结构

上述操作完成观察目录结构

九. Fabric CA使用

Hyperledger Fabric使用公钥基础设施（PKI）来验证所有网络参与者的行为。每个节点、网络管理员和提交交易的用户都需要有一个公共证书和私钥来验证其身份。这些身份需要有一个有效的信任根，确定这些证书是由一个网络成员的组织颁发的。network.sh脚本在创建peer节点和ordering节点之前，会创建所有部署和运行网络所需的加密材料。

1. 默认network.sh脚本使用cryptogen工具来创建证书和密钥
2. cryptogen工具用于开发和测试环境（为具有有效信任根的Fabric 组织快速创建所需的加密材料）

cryptogen 工具为 Org1、Org2 和 Orderer Org 创建证书和密钥。

测试和生产都可以使用CA创建组织身份。
生产环境：每个组织运行一个CA(或多个中间CA)
一个组织执行的CA创建的所有身份都共享一个信任根。

# 使用CA启动测试网络
./network down
./network.sh up -ca
# network.sh会调用organizations/fabric-ca/registerEnroll.sh脚本生成加密文件

使用Fabric CA客户端向每个组织的CA注册节点和用户身份。

1. 脚本使用 enroll 命令为每个身份生成一个 MSP 文件夹。
2. MSP文件夹包含了每个身份的证书和私钥，并建立了该身份在运营CA的组织中的角色和成员资格。
