Fabric 1.1.0下载

克隆hyperledger提供的fabric-samples项目

git clone https://github.com/hyperledger/fabric-samples.gitcd fabric-samples

git checkout v1.1.0 #切至1.1版本，以便跟后续安装的fabric版本相匹配

2. 下载fabric相关镜像和二进制文件

执行如下命令，下载fabric相关镜像和二进制文件（版本1.1.0）

curl -sSL https://goo.gl/6wtTN5 | bash -s 1.1.0

运行以下页面中的脚本自动下载镜像

https://hyperledger-fabric.readthedocs.io/en/release-1.2/install.html

1.1.0

docker pull hyperledger/fabric-ca:x86_64-1.1.0 \

&& docker pull hyperledger/fabric-peer:x86_64-1.1.0 \

&& docker pull hyperledger/fabric-orderer:x86_64-1.1.0 \

&& docker tag hyperledger/fabric-tools:x86_64-1.1.0 hyperledger/fabric-tools\

&& docker tag hyperledger/fabric-zookeeper:0.4.10 hyperledger/fabric-zookeeper\

启动docker

service docker start

启动docker实例

docker start 容器ID或容器名

1. 先查看已经暂停的容器实例信息

2. 通过docker start 59ec 启动容器

3. 通过docker ps 查看当前启动的容器

需要升级docker中的go版本

wget https://dl.google.com/go/go1.10.3.linux-amd64.tar.gz

sudo rm -rf /opt/go

sudo tar -C /opt -xzvf go1.10.3.linux-amd64.tar.gz

export $GOPATH=/opt/gopath

export $GOROOT=/usr/local/go

byfn.sh -m up

byfn.sh -m restart

(之后)

进⼊ docker 容器

docker exec -it cli bash

（之前必须docker-compose-cli.yaml中的cli command行改sleep

tail -f /dev/null

）

./scripts/script.sh mychannel

（开始）

往docker中传文件：

docker inspect -f '{{.Id}}' cli

194574f1b9ea4548a732291531e9f291ca488b0f4e5c19a364b843ba171b6835

docker cp /opt/gopath/src/mychaincode/ 194574f1b9ea4548a732291531e9f291ca488b0f4e5c19a364b843ba171b6835:/opt/gopath/src/

先要进docker

mkdir -p /opt/go/src/github.com/hyperledger/fabric

docker cp /opt/gopath/src/github.com/hyperledger/fabric

77815deec96b04d6ef5ab65ec95ecd77de0f45b0973e94604122d4f464c00bfa:/opt/go/src/github.com/hyperledger/

#从docker拷出文件

#docker cp 43e1a09ae943e91e721c72f70fc2282bb04a210da085de741404632e9c769e22:/opt/gopath/src/github.com/hyperledger/fabric/peer /opt/gopath/src/github.com/hyperledger/fabric/peer

# docker cp go1.10.3.linux-amd64.tar.gz 43e1a09ae943e91e721c72f70fc2282bb04a210da085de741404632e9c769e22:/opt/gopath/src/github.com/hyperledger/fabric

1、下载hyperledger/fabric-sample

2、切换到release-1.0

git checkout release-1.0

git branch -vv

3、下载bin到fabric-sample目录

https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/hyperledger-fabric/linux-amd64-1.0.0/

https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/hyperledger-fabric/linux-amd64-1.2.0/

wget https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/hyperledger-fabric/linux-amd64-1.2.0/hyperledger-fabric-linux-amd64-1.2.0.tar.gz

4、关闭

./byfn.sh -m down

3、进入first-network文件夹

./byfn.sh -m up

以下忽略，返回

#5、初始化

./byfn.sh -m generate

vi byfn.sh

⽣成初始区块（进入开发步骤）

$ ../bin/cryptogen generate --config=./crypto-config.yaml

$ export FABRIC_CFG_PATH=$PWD

$ ../bin/configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

$ ../bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP

操作⽹络(v1.2.0后不需要操作Alex.Zhang20180817)

编辑 docker-compose-cli.yaml ,注释到 command 命令

working_dir: /opt/gopath/src/github.com/hyperledger/fabric/peer #

command: /bin/bash -c './scripts/script.sh ${CHANNEL_NAME}; sleep

$TIMEOUT' volumes

操作网络

$ CHANNEL_NAME=$CHANNEL_NAME TIMEOUT=600 docker-compose -f docker-compose-cli.yaml up -d

进⼊ docker 容器

$ docker exec -it cli bash

创建通道

$ export CHANNEL_NAME=tangchannel

$ peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

加⼊通道

$ peer channel join -b tangchannel.block

(回上)

链上代码（链码）

安装链码

$ peer chaincode install -n tang -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02

实例化链码

$ peer chaincode instantiate -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n mycc -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}' -P "OR ('Org1MSP.member','Org2MSP.member')"

查询

$ peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}‘

转账

$ peer chaincode invoke -o orderer.example.com:7050 --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n mycc -c '{"Args":["invoke","a","b","10"]}’

以下启动REST API的web服务

在 GOPATH 的 root 目录中创建 docker-compose.yml 文件。粘贴以下内容：

membersrvc:

image: hyperledger/fabric-membersrvc

ports:

- "7054:7054"

command: membersrvc

部署示例

Hyperledger Fabric 提供了一个用于与该结构交互的 REST Web 服务接口。与 fabric 的第一次交互是部署链代码。确保本地区块链网络正在运行，然后启动 SoapUI，单击 REST 按钮创建一个新的 REST 项目。您会看到一个类似图 3 的对话框，在其中输入用于所有 REST 请求的基础 URL：

图 3. SoapUI New REST Project 对话框

输入 http://localhost:7050 作为 URL，然后单击 OK。端口 7050 是 fabric 使用的默认 REST 端口，而且因为区块链网络是在本地计算机上运行的，所以将使用 localhost 作为主机名。

在 SoapUI 启动后，可以执行一次快速冒烟测试，以确保它能与本地区块链网络进行通信。展开刚创建的新的 REST 资源，直到看到 Request 1，然后在 Editor 窗口中打开它。使用 GET 方法，在 resource 下输入 /chain。确保单击了 output 选项卡上的 JSON 选项，然后运行请求（通过单击 arrow 图标）。执行此请求时，会在 Editor 窗口右侧的输出选项卡中返回当前区块的哈希值，如图 4 所示

2、关闭原有例子

3、第一终端进入chaincode-docker-devmode，启动网络

docker-compose -f docker-compose-simple.yaml up

4、第二终端进入docker

docker exec -it chaincode bash

5、第二终端进入chaincode文件夹

/opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode

6、第二个终端启动chaincode

CORE_PEER_ADDRESS=peer:7051 CORE_CHAINCODE_ID_NAME=mycc:0 ./chaincode002

7、第三个终端

docker exec -it cli bash

安装链码

peer chaincode install -p chaincodedev/chaincode/chaincode002 -n mycc -v 0

实例化链码

peer chaincode instantiate -n mycc -v 0 -c '{"Args":["str","helloworld"]}' -C myc

# 查询链码

$ peer chaincode query -n mycc -c '{"Args":["get","str"]}' -C myc

# 调用链码

peer chaincode invoke -n mycc -c '{"Args":["set", "str", "helloworld111"]}'

-C myc

# 查询链码

$ peer chaincode query -n mycc -c '{"Args":["get","str"]}' -C myc

docker rm -f $(docker ps -aq)

chaincode002

链码放入：

if res.Status != shim.OK {

fmt.Println("Init failed", string(res.Message))

t.FailNow()

}

func checkQuery(t *testing.T, stub *shim.MockStub, name string) {

res := stub.MockInvoke("1", [][]byte{[]byte("get"), []byte(name)})

if res.Status != shim.OK {

fmt.Println("Query", name, "failed", string(res.Message))

t.FailNow()

}

if res.Payload == nil {

fmt.Println("Query", name, "failed to get value")

t.FailNow()

}

fmt.Println("Query value", name, "was ", string(res.Payload))

}

func checkInvoke(t *testing.T, stub *shim.MockStub, args [][]byte) {

}

func Test_Helloworld(t *testing.T) {

hello := new(Helloworld)

stub := shim.NewMockStub("hello", hello)

checkInit(t, stub, [][]byte{[]byte("str"), []byte("helloworld")})

checkQuery(t, stub, "str")

checkInvoke(t, stub, [][]byte{[]byte("set"), []byte("str"),[]byte("helloworld-1111")})

checkQuery(t, stub, "str")

}

通过 go test -v helloworld_test.go helloworld.go 测试相应的方法，运行结果：

=== RUN Test_Helloworld

helloworld init

Query value str was helloworld

helloworld set

Query value str was helloworld-1111

--- PASS: Test_Helloworld (0.00s)

PASS ok command-line-arguments 0.028s

Cloning an Example Business Network Definition

The sample business network definitions are stored on GitHub at https://github.com/hyperledger/composer-sample-networks. You can git clone this repository to pull down all the sample networks. Each sample network is stored under the packages directory.
