Fabcar 案例部署
本教程基於 Fabric-1.4.1 進行部署，部署環境是Centos7
官方文檔：點擊這里
准備好一個環境初始化好的虛擬機（教程地址）
原理
利用fabric-node-sdk程序來與Fabric網絡進行交互
准備工作
移除以往運行過的鏈碼鏡像和所有的容器:
# 查看鏡像
docker images
# 查看容器
docker ps -a
# 停止並移除所有容器
docker stop $(docker ps -aq) && docker rm $(docker ps -aq)
# 移除指定的鏡像
docker rmi 鏡像ID
安裝node和npm
# 創建目錄並進入目錄
mkdir -p /home/scripts && cd /home/scripts
# 下載node
wget https://nodejs.org/download/release/v8.9.4/node-v8.9.4-linux-x64.tar.gz
# 解壓node
tar -zxvf node-v8.9.4-linux-x64.tar.gz
# 復制到/opt目錄
mv node-v8.9.4-linux-x64 /opt
# 建立軟連接
ln -s /opt/node-v8.9.4-linux-x64/bin/node /usr/local/bin/node
ln -s /opt/node-v8.9.4-linux-x64/bin/npm /usr/local/bin/npm
# 查看版本
node -v
npm -v
設置淘寶鏡像
npm config set registry http://registry.npm.taobao.org/
npm install -g cnpm --registry=https://registry.npm.taobao.org
升級node和npm
Note: 可選操作
# npm升級到最新版本，-g全局安裝
cnpm install npm -g
# 已經升級了
npm -v
# 安裝nodejs的版本管理模塊n
cnpm install -g n
# 查看版本
n -V
# nodejs版本升級到最新，參數可換：latest/stable/lts/vx.x.x
n latest
# 安裝穩定版
n stable
# 安裝指定版本
n v7.10.0
# 查看已安裝版本
n
# 刪除指定版本
n rm 6.4.0
克隆Fabric-sample庫
工具下載
# 創建工作目錄並進入該目錄
mkdir -p /home/scripts && cd /home/scripts
# 下載腳本
curl -sS https://raw.githubusercontent.com/hyperledger/fabric/master/scripts/bootstrap.sh -o ./bootstrap.sh
# 賦予腳本執行權限
chmod +x ./bootstrap.sh
# 執行腳本來克隆fabric-samples庫
# 鏡像我們在前面的課程拉取過，這里跳過特定平台二進制文件的下載（很慢，自行通過瀏覽器下載，再上傳到虛擬機）
./bootstrap.sh 1.4.1 1.4.1 0.4.15 -d -b
# 如果沒有拉取fabric鏡像的執行下面這條命令
./bootstrap.sh 1.4.1 1.4.1 0.4.15 -b
# 將工具解壓到fabric-tools目錄（自行上傳，使用rz命令或者Filezilla工具均可以上傳）
tar -zxvf hyperledger-fabric-linux-amd64-1.4.1.tar.gz -C ./fabric-tools
# 將fabric-tools目錄下的bin文件夾復制到fabric-samples目錄下
cp -r ./fabric-tools/bin ./fabric-samples/bin
啟動網絡
# 進入fabcar目錄
cd /home/scripts/fabric-samples/fabcar
# 啟動網絡、創建通道、部署合約
./startFabric.sh javascript
安裝依賴
# 進入javascript目錄
cd /home/scripts/fabric-samples/fabcar/javascript
# 安裝依賴
npm install
注意：如果出現以下錯誤
npm WARN deprecated mkdirp@0.5.3: Legacy versions of mkdirp are no longer supported. Please update to mkdirp 1.x. (Note that the API surface has changed to use Promises in 1.x.)
