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

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/[email protected]/msp/admincerts/[email protected]"                         },                         "x-adminKeyStore": {                                 "path": "/YOUR_FABRIC_SAMPLE_PATH/basic-network/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/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
    at _cryptoSuite.importKey.then.then (/home/yan/workspace/marbles/node_modules/fabric-client/lib/User.js:255:45)
error: [fcw] could not format error
error: Exhausted all CAs. There are no more CAs to try.
error: could not enroll...
warn: Error enrolling admin

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
