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:

1# 查看镜像
2docker images
3
4# 查看容器
5docker ps -a
6
7# 停止并移除所有容器
8docker stop $(docker ps -aq) && docker rm $(docker ps -aq)
9
10# 移除指定的镜像
11docker rmi 镜像ID

安装node和npm

1# 创建目录并进入目录
2mkdir -p /home/scripts && cd /home/scripts
3
4# 下载node
5wget https://nodejs.org/download/release/v8.9.4/node-v8.9.4-linux-x64.tar.gz
6
7# 解压node
8tar -zxvf node-v8.9.4-linux-x64.tar.gz
9
10# 复制到/opt目录
11mv node-v8.9.4-linux-x64 /opt
12
13# 建立软连接
14ln -s /opt/node-v8.9.4-linux-x64/bin/node /usr/local/bin/node
15ln -s /opt/node-v8.9.4-linux-x64/bin/npm /usr/local/bin/npm
16
17# 查看版本
18node -v
19npm -v

设置淘宝镜像

1npm config set registry http://registry.npm.taobao.org/
2
3npm install -g cnpm --registry=https://registry.npm.taobao.org

升级node和npm

Note:<font color=orange> 可选操作 </font>

1# npm升级到最新版本，-g全局安装
2cnpm install npm -g
3
4# 已经升级了
5npm -v
6
7# 安装nodejs的版本管理模块n
8cnpm install -g n
9
10# 查看版本
11n -V
12
13# nodejs版本升级到最新，参数可换：latest/stable/lts/vx.x.x
14n latest
15
16# 安装稳定版
17n stable
18
19# 安装指定版本
20n v7.10.0
21
22#  查看已安装版本
23n
24
25# 删除指定版本
26n rm 6.4.0  

克隆Fabric-sample库

工具下载

1# 创建工作目录并进入该目录
2mkdir -p /home/scripts && cd /home/scripts
3
4# 下载脚本
5curl -sS https://raw.githubusercontent.com/hyperledger/fabric/master/scripts/bootstrap.sh -o ./bootstrap.sh
6
7# 赋予脚本执行权限
8chmod +x ./bootstrap.sh
9
10# 执行脚本来克隆fabric-samples库
11# 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）
12./bootstrap.sh 1.4.1 1.4.1 0.4.15 -d -b
13
14# 如果没有拉取fabric镜像的执行下面这条命令
15./bootstrap.sh 1.4.1 1.4.1 0.4.15 -b
16
17# 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）
18tar -zxvf hyperledger-fabric-linux-amd64-1.4.1.tar.gz -C ./fabric-tools
19
20# 将fabric-tools目录下的bin文件夹复制到fabric-samples目录下
21cp -r ./fabric-tools/bin ./fabric-samples/bin

启动网络

1# 进入fabcar目录
2cd /home/scripts/fabric-samples/fabcar
3
4# 启动网络、创建通道、部署合约
5./startFabric.sh javascript

安装依赖

1# 进入javascript目录
2cd /home/scripts/fabric-samples/fabcar/javascript
3
4# 安装依赖
5npm install

<font color=red>注意：如果出现以下错误</font>

1npm 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.)
