   $ cd $GOPATH/src/github.com/kongyixueyuan.com/

2. 下载项目

   $ git clone https://github.com/kevin-hf/education.git

3. 进入fixtures目录启动网络

   $ cd $GOPATH/src/github.com/kongyixueyuan.com/education/fixtures
   $ docker-compose up

4. 返回至项目根目录

   $ cd $GOPATH/src/github.com/kongyixueyuan.com/education

5. 编译

   $ go build

6. 启动服务

   $ ./education

7. 浏览器访问

   http://localhost:9000

8. 登录用户名及密码

   用户名：Hanxiaodong
   密码：123456
   

9. 停止服务

./education时，peer加入通道失败。

Fabric SDK初始化成功
通道已成功创建，

Peers加入通道失败: join channel failed: Multiple errors occurred:

SendProposal failed: Transaction processing for endorser [localhost:7151]: Endorser Client Status Code: (2) CONNECTION_FAILED. Description: dialing connection timed out [localhost:7151]

peer节点启动不了

环境都是一样的，应该是配置文件yml有问题吧，只有peer节点起不来

import cycle not allowed

在编译go build的时候总是报错：import cycle not allowed

请问该怎么解决？

这个web是用的什么框架哇

前端的{{}}调用语句我想改一下，但是不知道怎么改

请问如何实现不同用户对chaincode操作的访问控制

你好，我正在学习HyperLedger Fabric，之前只接触过公链，发现两者的账户体系有很大区别，非常想弄明白您这个项目中，如何限制不同用户访问chaincode不同接口的机制。在chaincode的源码中未发现相关的处理，望答复，谢谢。

创建通道失败问题

请问在go build之后，执行./education命令。报错如下：
Fabric SDK初始化成功
创建应用通道失败: create channel failed: SendEnvelope failed: calling orderer 'localhost:7050' failed: Orderer Server Status Code: (400) BAD_REQUEST. Description: error authorizing update: error validating ReadSet: readset expected key [Group] /Channel/Application at version 0, but got version 1
这个怎么解决呢？

docker-compose up 时couchdb报错

docker-compose up 时报错

请问这个怎么解决？

执行./education报错

据指定的资源管理客户端Context创建通道管理客户端失败: failed to create resmgmt client due to context error: user not found
这一步要怎么解决呢

./education 出现错误——请问有人帮忙看一下吗

关于configtx.yaml与crypto-config.yaml

您好！看到您的项目感觉非常感兴趣，想麻烦问一下您关于fixture文件夹里configtx.yaml与crypto-config.yaml这两个文件能不能给一下？万分感谢！

type Education struct的问题

这个ObjectType 是做什么用的

如何能够做到在多个机器节点部署？
