实战：区块链hyperledger fabric 初体验 - 4：基于区块链钻石交易展示平台的搭建-摩杜云开发者社区

本文Step by Step 搭建一个由IBM提供的基于Fabric的钻石交易展示平台。

本文环境是

ubuntu 16.04 4.4.0-104-generic

Docker version 17.03.0-ce, build 60ccb22

docker-compose version 1.14.0, build c7bdf9e

0.设置本地环境

0.1 安装git

省略

0.2 安装Go

下载Go for linux

https://studygolang.com/dl/golang/go1.10.linux-amd64.tar.gz

$ sudo tar -C /usr/local -xzf /your-download-path/go1.10.linux-amd64.tar.gz

修改.bashrc 添加
export PATH=$PATH:/usr/local/go/bin
执行~/.bashrc

$ source ~/.bashrc

验证安装结果

$ go version

0.3 安装Node.js

Download and install Node.js v6.2.0

https://nodejs.org/dist/v6.9.5/node-v6.9.5-linux-x64.tar.gz

安装

$ sudo tar -C /usr/local -xzf /your-download-pathnode-v6.9.5-linux-x64.tar.gz

修改.bashrc 添加
export PATH=$PATH:/usr/local/node-v6.9.5-linux-x64/bin
执行~/.bashrc

$ source ~/.bashrc

验证安装结果

$ node -v
$ npm -v

1、下载钻石交易应用

$ git clone https://github.com/IBM-Blockchain/marbles.git --depth 1
$ cd marbles/
$ git checkout master

2、创建区块链网络

2.1 下载Fabric Sample

$ git clone https://github.com/hyperledger/fabric-samples.git
$ cd fabric-samples

$ git checkout v1.1.0

$ curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/master/scripts/bootstrap.sh -o setup_script.sh

2.2 修改setup_script.sh

export VERSION=${1:-1.1.0}

export THIRDPARTY_IMAGE_VERSION=1.0.6

2.3 运行setup_script.sh下载平台相关的二进制文件和images

sudo bash setup_script.sh

2.4 为下载的image建立latest tag

docker tag hyperledger/fabric-tools:x86_64-1.1.0 hyperledger/fabric-tools:latest
docker tag hyperledger/fabric-orderer:x86_64-1.1.0 hyperledger/fabric-orderer:latest
docker tag hyperledger/fabric-peer:x86_64-1.1.0 hyperledger/fabric-peer:latest
docker tag hyperledger/fabric-javaenv:x86_64-1.1.0 hyperledger/fabric-javaenv:latest
docker tag hyperledger/fabric-ccenv:x86_64-1.1.0 hyperledger/fabric-ccenv:latest
docker tag hyperledger/fabric-couchdb:x86_64-1.0.6 hyperledger/fabric-couchdb:latest
docker tag hyperledger/fabric-kafka:x86_64-1.0.6 hyperledger/fabric-kafka:latest
docker tag hyperledger/fabric-zookeeper:x86_64-1.0.6 hyperledger/fabric-zookeeper:latest

2.5 编辑.bashrc把下载的二进制文件加入PATH环境变量

export PATH=$PWD/bin:$PATH

2.6 执行.bashrc

$ source ~/.bashrc

2.7 启动网络

$ cd ./fabcar
$ ./startFabric.sh

2.8 检查网络，执行docker ps 应该有红框内的5个containers.

2.9 安装测试所需的软件

$ npm install

2.10 用Fabcar测试网络

    node enrollAdmin.js
    node registerUser.js
    node query.js

3.安装并实例化链代码

3.1 安装

$ cd /YOUR_PATH/marbles/
$ npm install

3.2 再次执行下面脚本去创建证书

$ cd /YOUR_FABRIC_SAMPLE_PATH/fabcar

$ node enrollAdmin.js

$ node registerUser.js
$ node query.js

3.3 修改marbles/config/connection_profile_local.json

                "credentialStore": {
                        "path": "/YOUR_FABRIC_SAMPLE_PATH/fabcar/hfc-key-store"
                }
                        "x-adminCert": {
                                "path": "/YOUR_FABRIC_SAMPLE_PATH/basic-network/crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp/admincerts/Admin@org1.example.com-cert.pem"
                        },
                        "x-adminKeyStore": {
                                "path": "/YOUR_FABRIC_SAMPLE_PATH/basic-network/crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp/keystore/"
                        }

3.4 安装链码

$ ./scripts

$ node install_chaincode.js

3.5 实例化链码

$ node instantiate_chaincode.js

4. 托管 Marbles

$ cd ..
$ sudo npm install gulp -g

BTW: 解决“sudo: npm：找不到命令”问题

$ sudo ln -s /usr/local/node-v6.9.5-linux-x64/bin/node /usr/bin/node
$ sudo ln -s /usr/local/node-v6.9.5-linux-x64/lib/node /usr/lib/node
$ sudo ln -s /usr/local/node-v6.9.5-linux-x64/lib/npm /usr/lib/npm

$ npm install

4.5 运行钻石交易应用

$ gulp marbles_local

BTW：if you run into the issue like

error: [Client.js]: Failed to load user "admin" from local key value store. Error: TypeError: privateKey.isPublic is not a function
    at _cryptoSuite.importKey.then.then (/home/yan/workspace/marbles/node_modules/fabric-client/lib/User.js:255:45)
error: [Client.js]: Failed to load an instance of requested user "admin" from the state store on this Client instance. Error: TypeError: privateKey.isPublic is not a function
    at _cryptoSuite.importKey.then.then (/home/yan/workspace/marbles/node_modules/fabric-client/lib/User.js:255:45)
error: [fcw] Failed to get enrollment marblesDockerComposeNetworkmychannelOrg1MSPfabricpeerorg1 TypeError: privateKey.isPublic is not a function

you may need copy hfc-key-store directory to your home directory $HOME/.hfc-key-store, and re-config the client.credentialStore.path of connection_profile_local.json

5 使用 Marbles

5.1 访问http://localhost:3001/login
