Hyperledger Fabric 演练 - 《基于联盟区块链的政务大数据共享》
1. 背景
为了继续深入研究Fabric的加密通道逻辑，找了一个现成的例子，并修正了一个新手部署可能遇到的问题，
修正的主要点是
- 修改实例代码相对
fabric-samples路径， - 细化一些操作步骤，方便新手傻瓜式运行
1.1 区域链（基于证书准入的联盟链）网络
1.2 业务流程时序
2. 演示系统环境
OS: Ubuntu 18.04
Fabric: release-1.4
Go: go1.14.4 linux/amd64
Docker: 19.03.11
3. 源代码仓库
gitee: https://gitee.com/BCSkill/fcc
4. 实例部署
4.1 克隆源代码
git clone https://gitee.com/BCSkill/fcc.git4.2 部署fabric-samples运行环境
细节的话可以参考《fabric-samples 部署测试》，我们这里不做详细描述，直接运行封装好的脚本
./1-1.hy-sample.sh大概过程中会分为几步，
- 克隆
fabric-samples到当前源码目录 - 下载编译到好的
fabric二进制文件，并解压到fabric-samples/bin,记得将此目录添加到环境变量 - 拉取所需要的Docker镜像
4.3 启动示例网络，创建区块链网络（2个组织，每组织2个节点）
./1-2.startNetwork.sh成功后输出========= All GOOD, BYFN execution completed ===========
4.4 加入第3个组织，2个节点
./2.addOrg3.sh完成后，结果显示========= Org3 is now halfway onto your first network =========
4.5 部署政务智能合约，并实例化
./3-1.installNetcon.sh #合约：网签合同备案
./3-2.installEstateBook.sh #合约：不动产权证书
./3-3.installEstateTax.sh #合约：不动产业务缴税完成后，结果显示
Get instantiated chaincodes on channel mychannel:
Name: estatebook, Version: 1.0, Path: github.com/chaincode/estatebook, Escc: escc, Vscc: vscc
Name: estatetax, Version: 1.0, Path: github.com/chaincode/estatetax, Escc: escc, Vscc: vscc
Name: netcon, Version: 1.0, Path: github.com/chaincode/netcon, Escc: escc, Vscc: vscc此时链环境和链合约已经部署好了。下面开始部署项目的服务端和Web前台
4.6 编译后台。
代码位于appcode/fccserver/src 可自行编译，或直接使用已编译完成的可执行文件
chmod +x appcode/fccserver/src/fccserver启动后台容器
./4.startAppcli.sh
docker logs -f appcli如果启动正常，会显示
[fcc-server] 2019/12/12 03:03:55 system db initiated successfully.
[fcc-server] 2019/12/12 03:03:56 Chaincode client initialed successfully.
[fcc-server] 2019/12/12 03:03:56 Server started on :12064.7 编译和部署前端
前端采用VUE，也可使用其它前端框架或HTML。使用GNINX或其它WEB服务器部署编译后的前端代码。注：当前未使用登录和权限设置
前台部署依赖yarn,《ubuntu 安装最新版本 yarn》
cd ./appcode/fcc-client // 进到Web前端代码目录
yarn install // 安装依赖
yarn serve // 运行前端如果出现
运行成功后，就会显示访问地址
App running at:
- Local: http://localhost:8080/
- Network: http://192.168.31.134:8080/浏览器打开地址，就能看到实例演示了
