使用fabric-sdk-go 構建第一個區塊鏈程式 之【搭建fabric網路】
阿新 • • 發佈：2018-12-11
環境：mac os
準備：
Docker:
- 先註冊docker hub的一個賬號->docker hub
- 下載安裝docker下載地址
- 使用之前註冊好的賬號進行登入
- 切換映象源，推薦使用daocloude註冊地址(具體更換方法自行百度吧)
ps: docker for mac 不需要單獨在安裝docker-compose, centos 或者 ubuntu 需要單獨進行安裝
Go: 這個肯定不用說了~~~ 相信您已經安裝了
安裝指南
使用 Hyperledger fabric 1.0.5構建一個簡單的網路
1、建立專案目錄
mkdir -p $GOPATH/src/github.com/chainHero/heroes-service-network
2、這裡為了簡化部署網路部署，提供了二進位制檔案，方便安裝
倉庫地址： (Linux x64 ):
cd $GOPATH/src/github.com/chainHero/heroes-service-network && git clone https://github.com/chainHero/heroes-service-network/branches/master/bin
ps：這個地址貌似有點問題所以提供了下面的下載連結，解壓後將整個bin目錄移動到 之前建好的目錄中
3、我們要知道我們的網路由那些東西組成所以需要一個配置檔案，配置檔案包含網路拓撲，並根據組織和元件生成證書和祕鑰
cd $GOPATH/src/github.com/chainHero/heroes-service-network && touch crypto-config.yaml && vim crypto-config.yaml
並將下面的內容複製到crypto-config.yaml 檔案中 （檔案內容申明瞭我們的網路有一個組織和兩個peer 節點）
# "OrdererOrgs" - Definition of organizations managing orderer nodes OrdererOrgs: - Name: ChainHero Domain: hf.chainhero.io # Specs is an array of Spec entries. Each Spec entry consists of two fields : Hostname and CommonName Specs: - Hostname: orderer # "PeerOrgs" - Definition of organizations managing peer nodes PeerOrgs: - Name: Org1ChainHero Domain: org1.hf.chainhero.io # Allows for the definition of 1 or more hosts that are created sequentially # from a template. By default, this looks like "peer%d" from 0 to Count-1. # You may override the number of nodes (Count), the starting index (Start) # or the template used to construct the name (Hostname). Template: Count: 2 Users: # The number of user accounts _in addition_ to Admin Count: 2
4、使用Cryptogen 生成加密材料
cd $GOPATH/src/github.com/chainHero/heroes-service-network && mkdir -p crypto-config && ./bin/cryptogen generate --config=./crypto-config.yaml
這時候crypto-config下就多了兩個資料夾
5、為了初始化我們的網路我們還需要做一下操作：
- 創世區塊
- channel
- peer 節點
繼續我們的操作
cd $GOPATH/src/github.com/chainHero/heroes-service-network && touch configtx.yaml && vim configtx.yaml
將一下內容複製到configtx.yaml 中

配置檔案已經生成好了，我們需要用configtxgen 來生成我們的創世區塊
cd $GOPATH/src/github.com/chainHero/heroes-service-network &&
mkdir -p artifacts
cd $GOPATH/src/github.com/chainHero/heroes-service-network &&
FABRIC_CFG_PATH=$PWD ./bin/configtxgen -profile ChainHero -outputBlock ./artifacts/orderer.genesis.block
建立我們的channel
FABRIC_CFG_PATH=$PWD ./bin/configtxgen -profile ChainHero -outputCreateChannelTx ./artifacts/chainhero.channel.tx -channelID chainhero
建立一個peer 節點
FABRIC_CFG_PATH=$PWD ./bin/configtxgen -profile ChainHero -outputAnchorPeersUpdate ./artifacts/org1.chainhero.anchors.tx -channelID chainhero -asOrg ChainHeroOrganization1
區塊鏈網路我們已經搭建完成了，接下來是怎麼啟動他們~~~
我們使用docker-compose來啟動建立一個docker-compose.yaml檔案

這需要改動一點東西：
將內容中的 --HERE--替換為heroes-service-network/crypto-config/peerOrganizations/org1.hf.chainhero.io/ca/xxxx_sk
這裡的xxxx_sk圖中的檔名
啟動網路：
cd $GOPATH/src/github.com/chainHero/heroes-service-network && docker-compose up -d
檢視容器是否都啟動了
第一部分已經完成
