1. 打开Docker拉取镜像，在https://hub.docker.com/可以查看镜像版本，为了配合毕设我们拉取0.6版本，并把tag重命名为latest

docker pull hyperledger/ fabric-peer:x86\_64-0.6.1-preview

docker pull hyperledger/ fabric-membersrvc:latest

docker images

![SouthEast 1][]

![SouthEast 2][]

2. 将编写好的docker-compose.yml保存到本地c/Users/rjy以便后续运行使用

membersrvc:
      image: hyperledger/fabric-membersrvc
      ports:
        - "7054:7054"
      command: membersrvc
    vp0:
      image: hyperledger/fabric-peer
      ports:
        - "7050:7050"
        - "7051:7051"
        - "7053:7053"
      environment:
        - CORE_PEER_ADDRESSAUTODETECT=true
        - CORE_VM_ENDPOINT=unix:///var/run/docker.sock
        - CORE_LOGGING_LEVEL=DEBUG
        - CORE_PEER_ID=vp0
        - CORE_PEER_PKI_ECA_PADDR=membersrvc:7054
        - CORE_PEER_PKI_TCA_PADDR=membersrvc:7054
        - CORE_PEER_PKI_TLSCA_PADDR=membersrvc:7054
        - CORE_SECURITY_ENABLED=true
        - CORE_SECURITY_ENROLLID=test_vp0
        - CORE_SECURITY_ENROLLSECRET=MwYpmSRjupbT
      links:
        - membersrvc
      command: sh -c "sleep 5; peer node start --peer-chaincodedev"

3. docker输入docker-compose up

![SouthEast 3][]

4. mRemoteNG链接Docker，

Host : 192.168.99.100

User name : docker

Password : tcuser

协议 : SSHv2

![SouthEast 4][]

5. mRemoteNG输入docker ps

![SouthEast 5][]

6. mRemoteNG输入docker exec -it rjy\_vp0\_1 bash

7. 退回到.../github.com新建一个SaveState文件夹 mkdir SaveState

8. 进入SaveState，输入vi SaveState2.go新建一个SaveState.go文件

9. 按下i键，从下面复制代码，在mRemoteNG点击右键粘贴过来

package main
     
    import (
        "errors"
        "fmt"
        
     
        "github.com/hyperledger/fabric/core/chaincode/shim"
    )
     
     
    type SaveState2Chaincode struct {
    }
     
    func (t *SaveState2Chaincode) Init(stub shim.ChaincodeStubInterface, function string, args []string) ([]byte, error) {
        fmt.Printf("Init called with function %s!\n", function)
     
        return nil, nil
    }
     
    func (t *SaveState2Chaincode) Invoke(stub shim.ChaincodeStubInterface, function string, args []string) ([]byte, error) {
        fmt.Printf("Invoke called with function %s!\n", function)
     
        var key, value string
        key = args[0]
        value = args[1]
     
        var err error
        err = stub.PutState(key, []byte(value))
     
        if err != nil {
            return nil, err
        }
        return nil, nil    
    }
     
     
    func (t *SaveState2Chaincode) Query(stub shim.ChaincodeStubInterface, function string, args []string) ([]byte, error) {
        fmt.Printf("Query called with function %s!\n", function)
     
        var key string
        key = args[0]
     
        valInBytes, err := stub.GetState(key)
     
        if err != nil {
            return nil, errors.New("Failed to get state for " + key)
        }
     
        message := "State for "  + key + " = " + string(valInBytes)
     
        return []byte(message), nil
    }
     
    func main() {
        err := shim.Start(new(SaveState2Chaincode))
        if err != nil {
            fmt.Printf("Error starting Save State chaincode: %s", err)
        }
    }

10. :wq

11. go build ./   注意build后边有一个空格，运行完这一句会出现一个绿色的文件

12. export CORE\_CHAINCODE\_ID\_NAME=mycc

13. export CORE\_PEER\_ADDRESS=0.0.0.0:7051

14. ./SaveState &

15. 向Hyperledger服务接口http://192.168.99.100:7050/registrar 发送如下REST请求，使用内置的jim用户登录系统

"enrollId": "jim",

"enrollSecret": "6avZQLwcUe9b"

16. 向Hyperledger服务接口http://192.168.99.100:7050/chaincode 发送如下REST请求
