Fabcar 案例部署

本教程基于 Fabric-1.4.1 进行部署，部署环境是Centos7

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 config set registry http://registry.npm.taobao.org/

npm install -g cnpm --registry=https://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

工具下载

# 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

# 将工具解压到fabric-tools目录（自行上传，使用rz命令或者Filezilla工具均可以上传）
tar -zxvf hyperledger-fabric-linux-amd64-1.4.1.tar.gz -C ./fabric-tools

# 将fabric-tools目录下的bin文件夹复制到fabric-samples目录下
cp -r ./fabric-tools/bin ./fabric-samples/bin

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 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.)
npm WARN deprecated mkdirp@0.5.1: 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.)
