CnetOS 7.4 部署 Hyperledger Fabric 1.4

VMware 安裝 CentOS 7.4 請參考 https://blog.csdn.net/qq_39135287/article/details/83993574 前兩部分即可，其中第二部分步驟20可省略

1. 關閉CentOS防火牆

systemctl stop firewalld && systemctl disable firewalld

2. 安裝環境

• curl、git、Python系統自帶，無需安裝

• Docker安裝，官方示例 https://docs.docker.com/install/linux/docker-ce/centos/

  yum install -y yum-utils device-mapper-persistent-data lvm2
  
  yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
  
  yum makecache fast
  
  yum -y install docker-ce
  
  mkdir -p  /etc/docker/
  
  echo -e '{\n  "data-root":"/home/docker",\n  "registry-mirrors": ["https://1e7waog4.mirror.aliyuncs.com"]\n}' > /etc/docker/daemon.json
  
  systemctl start docker && systemctl enable docker
  
  # 驗證版本
  docker --version
  

• Docker-Compose安裝，官方示例 https://github.com/docker/compose/releases

  sudo curl -L https://github.com/docker/compose/releases/download/1.25.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
  
  sudo chmod +x /usr/local/bin/docker-compose
  
  # 驗證版本
  docker-compose --version
  

• GO語言安裝，資源路徑 https://golang.google.cn/dl/

  wget https://studygolang.com/dl/golang/go1.11.13.linux-amd64.tar.gz -O /opt/go1.11.13.linux-amd64.tar.gz
  
  cd /opt/
  
  tar -zxvf go1.11.13.linux-amd64.tar.gz
  
  rm -rf /opt/go1.11.13.linux-amd64.tar.gz
  
  mkdir /opt/gopath
  
  echo -e 'export GOROOT=/opt/go \n export GOBIN=$GOROOT/bin \n export PATH=$PATH:$GOBIN \n export GOPATH=/opt/gopath' >> /etc/profile
  
  source /etc/profile
  
  # 驗證版本
  go version
  

• Node.js安裝

  wget https://npm.taobao.org/mirrors/node/v8.9.4/node-v8.9.4-linux-x64.tar.xz -O /opt/node-v8.9.4-linux-x64.tar.xz
  
  cd /opt/
  
  tar -xvf node-v8.9.4-linux-x64.tar.xz
  
  rm -rf /opt/node-v8.9.4-linux-x64.tar.xz
  
  ln -s /opt/node-v8.9.4-linux-x64/bin/npm /usr/local/bin/npm
  
  ln -s /opt/node-v8.9.4-linux-x64/bin/node /usr/local/bin/node
  
  # 驗證版本
  node -v

3. 安裝Fabric

mkdir -p $GOPATH/src/github.com/hyperledger

cd $GOPATH/src/github.com/hyperledger

git clone https://github.com/hyperledger/fabric.git

cd fabric

git checkout v1.4.0

echo 'export PATH=$GOPATH/src/github.com/hyperledger/fabric/scripts/fabric-samples/bin:$PATH' >> /etc/profile

source /etc/profile

cd scripts

./bootstrap.sh

---

4. 構建及管理Fabric網絡

官方示例：https://hyperledgercn.github.io/hyperledgerDocs/build_network_zh/

• 運行fabric

  cd $GOPATH/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network
  
  ./byfn.sh generate
  
  ./byfn.sh up
  

• 查看到節點啓動情況

  docker ps
  

• 停止網絡

  ./byfn.sh down
  

---

至此Fabric已在CentOS部署完畢

---

部署ChainCode

• 在下方目錄內新建文件夾chaincode_test，並將編寫好的ChainCode放在其中（重點）

  # 網上很多示例說是把 chaincode 放在
  # 	/opt/gopath/src/github.com/hyperledger/fabric/examples/chaincode 裏面
  # 但是我試了很多次都不行
  # 後來看了第4步 ./byfn.sh up 時打印的信息
  # 	peer chaincode install -n mycc -v 1.0 -l golang -p github.com/chaincode/chaincode_example02/go/
  # 發現如果路徑不是 github.com/chaincode/... 就會報錯
  
  /opt/gopath/src/github.com/hyperledger/fabric/scripts/fabric/fabric-samples/chaincode
  

• 切換節點

  docker exec -it cli bash
  
  CORE_PEER_LOCALMSPID="Org1MSP" 
  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 
  CORE_PEER_ADDRESS=peer0.org1.example.com:7051
  

• 安裝ChainCode，可參照第4步 ./byfn.sh up 時的打印信息

  peer chaincode install -n testcc -v 1.0 -l golang -p github.com/chaincode/chaincode_test
  

• 實例化ChainCode，可參照第4步 ./byfn.sh up 時的打印信息

  peer chaincode instantiate -o orderer.example.com:7050 --tls true --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 mychannel -n testcc -l golang -v 1.0 -c '{"Args":[""]}' -P "OR ('Org1MSP.member','Org2MSP.member')"
  

• 切換至節點org2，再次安裝ChainCode，此次無需實例化

  CORE_PEER_LOCALMSPID="Org2MSP" 
  CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt 
  CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/[email protected]/msp 
  CORE_PEER_ADDRESS=peer0.org2.example.com:7051
  

• 可根據ChainCode執行query和invoke

安裝區塊鏈瀏覽器可參照上篇文章

• 直接安裝jq會報錯，需按以下步驟操作

  yum install epel-release
  
  yum install jq
  

• 構建Hyperledger Explorer ./main.sh install 報錯

  gyp WARN EACCES user "root" does not have permission to access the dev dir "/opt/gopath/src/github.com/hyperledger/blockchain-explorer/node_modules/pkcs11js/.node-gyp/8.9.4"
  gyp WARN EACCES attempting to reinstall using temporary dev dir "/opt/gopath/src/github.com/hyperledger/blockchain-explorer/node_modules/pkcs11js/.node-gyp"
  
  # 修改 main.sh 文件
  # 在所有 npm install $VERBOSE 後面添加 --unsafe-perm 跳過權限驗證
  # function do_install () {
  #		...
  #		npm install $VERBOSE --unsafe-perm=true --allow-root
  # }	
  

• Hyperledger Explorer ./start.sh 報錯

  # error 信息
  ['Default client peer is down and no channel details available database']
  
  # 解決方案
  # 修改 blockchain-explorer/app/platform/fabric/connection-profile/first-network.json
  # true 改爲 false
  "tlsEnable" : false
  # grpcs 改爲 grpc
  "url" : "grpc://localhost:7051",
  "eventUrl" : "grpc://localhost:7053"
