hyperledger fabric1.0动态添加peer节点之添加peer节点

前言：

在前面已经介绍了环境和证书（fabric-ca），不明白的地方可先查阅前两篇文章。

hyperledger fabric1.0动态添加peer节点之fabric-ca环境配置

hyperledger fabric1.0动态添加peer节点之fabric-ca应用

一、新增节点证书文件

从上篇文章中已获取到了peer2目录，这里参照peer0.org1.example.com或peer1.org1.example.com新增peer2.org1.example.com，并将msp目录替换，tls目录可以为空，上篇中已经关闭了tls功能。

二、修改network_setup.sh

#文件最后进行修改
#新增dynamic判断
if [ "${UP_DOWN}" == "up" ]; then
	networkUp
elif [ "${UP_DOWN}" == "dynamic" ]; then ## Clear the network
    networkDynamic
elif [ "${UP_DOWN}" == "down" ]; then ## Clear the network
	networkDown
elif [ "${UP_DOWN}" == "restart" ]; then ## Restart the network
	networkDown
	networkUp
else
	printHelp
	exit 1
fi

#同时在文件上方新增networkDynamic方法

function networkDynamic () {
    if [ -f "./crypto-config" ]; then
      echo "crypto-config directory already exists."
      exit 1
    fi
    CHANNEL_NAME=$CH_NAME TIMEOUT=$CLI_TIMEOUT docker-compose -f $COMPOSE_FILE_dynamic up -d 2>&1
    docker logs -f cli-dynamic
}

#networkDynamic方法新增了变量$COMPOSE_FILE_dynamic
#文件大概17行新增变量

COMPOSE_FILE_dynamic=docker-compose-dynamic.yaml

三、新增docker-compose-dynamic.yaml文件

我们为新增的节点重新创建文件，不去影响之前的启动文件。具体如下

version: '2'

services:
  peer2.org1.example.com:
    container_name: peer2.org1.example.com
    extends:
      file:  base/docker-compose-dynamic.yaml
      service: peer2.org1.example.com

  cli-dynamic:
    container_name: cli-dynamic
    image: hyperledger/fabric-tools
    tty: true
    environment:
      - GOPATH=/opt/gopath
      - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
      - CORE_LOGGING_LEVEL=DEBUG
      - CORE_PEER_ID=cli-dynamic
      - CORE_PEER_ADDRESS=peer0.org1.example.com:7051
      - CORE_PEER_LOCALMSPID=Org1MSP
      - CORE_PEER_TLS_ENABLED=false
      - CORE_PEER_TLS_CERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.crt
      - CORE_PEER_TLS_KEY_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.key
      - CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
      - CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp
    working_dir: /opt/gopath/src/github.com/hyperledger/fabric/peer
    command: /bin/bash -c './scripts/script_dy.sh ${CHANNEL_NAME}; sleep $TIMEOUT'
    volumes:
        - /var/run/:/host/var/run/
        - ../chaincode/go/:/opt/gopath/src/github.com/hyperledger/fabric/examples/chaincode/go
        - ./crypto-config:/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/
        - ./scripts:/opt/gopath/src/github.com/hyperledger/fabric/peer/scripts/
        - ./channel-artifacts:/opt/gopath/src/github.com/hyperledger/fabric/peer/channel-artifacts
        - ./channel/mychannel.block:/opt/gopath/src/github.com/hyperledger/fabric/peer/mychannel.block
    depends_on:
      - peer2.org1.example.com

新增添加的启动节点和cli-dynamic，新增了文件base/docker-compose-dynamic.yaml和scripts/script_dy.sh，并在之前的cli容器的基础上多映射了一个目录文件channel/mychannel.block。

四、新增base/docker-compose-dynamic.yaml

version: '2'

services:

  peer2.org1.example.com:
    container_name: peer0.org1.example.com
    extends:
      file: peer-base.yaml
      service: peer-base
    environment:
      - CORE_PEER_ID=peer2.org1.example.com
      - CORE_PEER_ADDRESS=peer2.org1.example.com:7051
      - CORE_PEER_CHAINCODELISTENADDRESS=peer2.org1.example.com:7052
      - CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer2.org1.example.com:7051
      - CORE_PEER_GOSSIP_BOOTSTRAP=peer0.org1.example.com:7051
      - CORE_PEER_LOCALMSPID=Org1MSP
    volumes:
        - /var/run/:/host/var/run/
        - ../crypto-config/peerOrganizations/org1.example.com/peers/peer2.org1.example.com/msp:/etc/hyperledger/fabric/msp
        - ../crypto-config/peerOrganizations/org1.example.com/peers/peer2.org1.example.com/tls:/etc/hyperledger/fabric/tls
    ports:
      - 6051:7051
      - 6052:7052
      - 6053:7053

注意：端口号可以自行配置，映射端口不可修改。组织锚节点不可随意修改。

五、通道block文件

通道文件需要使用网络启动时创建通道生成的文件，此文件在cli容器中，需要先从容器中拷贝一份。

#拷贝容器文件到主机目录
docker cp cli:/opt/gopath/src/github.com/hyperledger/fabric/peer/mychannel.block  /Users/cuishuai/Documents/

#在e2e_cli中新增channel目录
#将mychannel.block文件拷贝至channel目录

六、新增scripts/script_dy.sh

#复制scripts/script.sh文件
#大概190行，删除createChannel，updateAnchorPeers

#修改joinChannel方法
for ch in 0 1 2 3; do
为
for ch in 0; do

#修改setGlobals方法

CORE_PEER_ADDRESS=peer0.org1.example.com:7051
为
CORE_PEER_ADDRESS=peer2.org1.example.com:7051

#大概190行之后的执行内容如下

## Join all the peers to the channel
echo "Having all peers join the channel..."
joinChannel

## Install chaincode on Peer0/Org1 and Peer2/Org2
echo "Installing chaincode on org1/peer0..."
installChaincode 0

echo "Instantiating chaincode on org1/peer0..."
instantiateChaincode 0

#Query on chaincode on Peer0/Org1
echo "Querying chaincode on org1/peer0..."
chaincodeQuery 0 90

#Invoke on chaincode on Peer0/Org1
echo "Sending invoke transaction on org1/peer0..."
chaincodeInvoke 0

注意：chaincodeQuery 0 90 此处的90为账本中的数，启动网络时由于进行了一个invoke操作，值由100变为了90，这里90做为验证，如果这里的值与账本中的值不一致，程序执行到这里时超时。如果不确定账本中的值为多少时，可查看链码容器日志

docker logs dev-peer2.org1.example.com-mycc-1.0

七、执行命令

#执行新增命令
./network_setup.sh dynamic
#如果新增过程中出现问题，可单独结束已启的容器
#查看所有容器
docker ps -a
docker rm -f 容器ID
#如果使用./network_setup.sh down会停止整个网络。
