Fabcar 案例部署
本教程基于 Fabric-1.4.1 进行部署
官方文档：点击这里
准备好一个环境初始化好的虚拟机（教程地址）
原理
利用fabric-node-sdk程序来与Fabric网络进行交互
准备工作
移除以往运行过的链码镜像和所有的容器:
# 查看镜像
docker images
# 查看容器
docker ps -a
# 停止并移除所有容器
docker stop $(docker ps -aq) && docker rm $(docker ps -aq)
# 移除指定的镜像
docker rmi 镜像ID
安装node和npm
# 创建目录并进入目录
mkdir -p /home/scripts && cd /home/scripts
# 下载node
wget https://nodejs.org/download/release/v8.9.4/node-v8.9.4-linux-x64.tar.gz
# 解压node
tar -zxvf node-v8.9.4-linux-x64.tar.gz
# 复制到/opt目录
mv node-v8.9.4-linux-x64 /opt
# 建立软连接
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
设置淘宝镜像
npm install -g cnpm --registry=https://registry.npm.taobao.org
npm config set registry http://registry.npm.taobao.org/
升级node和npm
Note: 可选操作
# npm升级到最新版本，-g全局安装
cnpm install npm -g
# 已经升级了
npm -v
# 安装nodejs的版本管理模块n
cnpm install -g n
# 查看版本
n -V
# nodejs版本升级到最新，参数可换：latest/stable/lts/vx.x.x
n latest
# 安装稳定版
n stable
# 安装指定版本
n v7.10.0
# 查看已安装版本
n
# 删除指定版本
n rm 6.4.0
克隆Fabric-sample库
# 创建工作目录并进入该目录
mkdir -p /home/scripts && cd /home/scripts
# 下载脚本
curl -sS https://raw.githubusercontent.com/hyperledger/fabric/master/scripts/bootstrap.sh -o ./bootstrap.sh
# 赋予脚本执行权限
chmod +x ./bootstrap.sh
# 执行脚本来克隆fabric-samples库
# 镜像我们在前面的课程拉取过，这里跳过特定平台二进制文件的下载（很慢，自行通过浏览器下载，再上传到虚拟机）
./bootstrap.sh 1.4.1 1.4.1 0.4.15 -d -b
# 如果没有拉取fabric镜像的执行下面这条命令
./bootstrap.sh 1.4.1 1.4.1 0.4.15 -b
启动网络
# 进入fabcar目录
cd /home/scripts/fabric-samples/fabcar
# 启动网络、创建通道、部署合约
./startFabric.sh javascript
安装依赖
# 进入javascript目录
cd /home/scripts/fabric-samples/fabcar/javascript
# 安装依赖
npm install
注意：如果出现以下错误
npm WARN deprecated [email protected]: 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.)
