前言

Marbles專案的底層網路是Hyperledger Fabric（分散式的超級賬本），該專案最終會呈獻給我們通過圖形化介面，可以用來操作marbles。可以新增使用者，新增marble,刪除marble，交易marble，這些操作都會記錄到區塊鏈上。
　　啟動專案之前需要一些指定的設定，並且我們選擇搭建本地的Hyperledger Network來執行專案。我的系統環境：Ubuntu16.04。

設定

1 環境搭建

• 需要安裝(版本號要嚴格按照下面的來設定)：

  • Git
  • GoLang - 1.7.0 or higher(要設定好GOPATH)
  • Docker - v1.13 or higher
  • Node.js - node v6.2.0 - v6.10.0 (v7+不支援)

• 驗證安裝：

   	$  git  --version
   	git version 2.7.4
   	  
   	$  go version
   	go version go1.8.3 linux/amd64
   	
   	$  echo $GOPATH
   	/media/jiang/newspace/project/mygo
   	
   	$   docker -v
   	Docker version 17.06.0-ce, build 02c1d87
   	
   	$  docker-compose  -v
   	docker-compose version 1.14.0, build c7bdf9e
   	
   	$  node -v
   	v6.10.0
   	
   	$  npm -v
   	3.10.10
   
  

2 下載marbles倉庫

• 定位到存放目錄，執行命令：

   git clone https://github.com/IBM-Blockchain/marbles.git --depth 1
   git checkout v3.0
  

3 設定本地區塊鏈網路

•  cd marbles/scripts
   chmod +x download-dockerimages.sh
   sudo ./download-dockerimages.sh
  

  • 指令碼完成後會在命令列面板裡看到:

• 設定Fabric Node SDK

   cd marbles/scripts
   bash setup_sdk.sh
  

  指令碼執行完成後，會在scripts目錄下生成fabric-sdk-node資料夾。

  • 那麼這個指令碼都執行了什麼操作呢，請看下面：

     #!/bin/bash
     set -e
     
     # １　下載 SDK
     git clone https://github.com/hyperledger/fabric-sdk-node.git
     sleep 1
     cd ./fabric-sdk-node
     git checkout v1.0.0-alpha
     git branch
     sleep 1
     
     # 2 安裝依賴
     npm install
     npm install -g gulp
     gulp ca
     
     # 3 拷貝docker-compose 檔案到SDK指定資料夾
     cd ../
     cp ./docker-compose-marblesv3.yaml fabric-sdk-node/test/fixtures
     
     # 4 拷貝配置檔案到SDK指定資料夾
     cp ./config.json fabric-sdk-node/test/integration/e2e
     　　　
    

• 啟動網路

   docker rm -f $(docker ps -aq)
   cd ./fabric-sdk-node/test/fixtures
   docker-compose -f docker-compose-marblesv3.yaml up -d
  

  • 一旦執行成功，執行docker ps命令，會看到docker中有8個執行中的容器：

     CONTAINER ID        IMAGE                        COMMAND                  CREATED             STATUS                       PORTS                                            NAMES
