實戰：區塊鏈hyperledger fabric 初體驗 - 4：基於區塊鏈鑽石交易展示平臺的搭建

本文Step by Step 搭建一個由IBM提供的基於Fabric的鑽石交易展示平臺。

本文環境是

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.設置本地環境

0.1 安裝git

省略

0.2 安裝Go

下載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
執行~/.bashrc

$ source ~/.bashrc

驗證安裝結果

$ go version

0.3 安裝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

安裝

$ 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
執行~/.bashrc

$ source ~/.bashrc

驗證安裝結果

$ node -v
$ npm -v

1、下載鑽石交易應用

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

2、創建區塊鏈網絡

2.1 下載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 運行setup_script.sh下載平臺相關的二進制文件和images

sudo bash setup_script.sh

2.4 爲下載的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 編輯.bashrc把下載的二進制文件加入PATH環境變量

export PATH=$PWD/bin:$PATH

2.6 執行.bashrc

$ source ~/.bashrc

2.7 啓動網絡

$ cd ./fabcar
$ ./startFabric.sh

2.8 檢查網絡，執行docker ps 應該有紅框內的5個containers.

2.9 安裝測試所需的軟件

$ npm install

2.10 用Fabcar測試網絡

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

3.安裝並實例化鏈代碼

3.1 安裝

$ cd /YOUR_PATH/marbles/
$ npm install

3.2 再次執行下面腳本去創建證書

$ 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 安裝鏈碼

$ ./scripts

$ node install_chaincode.js

3.5 實例化鏈碼

$ node instantiate_chaincode.js

4. 託管 Marbles

$ cd ..
$ sudo npm install gulp -g

BTW: 解決“sudo: npm：找不到命令”問題

$ 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 運行鑽石交易應用

$ 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
