Fabric区块链浏览器搭建

书接这一回 Fabric二进制建链，在建好链之后，将为这条链部署一个区块链浏览器。

• Hyperledger Fabric区块链浏览器地址：https://github.com/hyperledger-labs/blockchain-explorer

一、创建区块链浏览器相关目录

mkdir -p /home/songzehao/fabric/explorer/connection-profile
1

二、配置docker-compose

vim /home/songzehao/fabric/explorer/docker-compose.yaml
1

内容如下：

​
volumes:
  pgdata:
  walletstore:
​
networks:
  mynetwork.com:
    external: false
    name: fabric_dev
​
services:

    container_name: explorerdb.mynetwork.com
    hostname: explorerdb.mynetwork.com
    environment:
      - DATABASE_DATABASE=fabricexplorer
      - DATABASE_USERNAME=hppoc
      - DATABASE_PASSWORD=password
    healthcheck:
      test: "pg_isready -h localhost -p 5432 -q -U postgres"
      interval: 30s
      timeout: 10s
      retries: 5
    volumes:
      - pgdata:/var/lib/postgresql/data
    networks:

    hostname: explorer.mynetwork.com
    environment:
      - DATABASE_HOST=explorerdb.mynetwork.com
      - DATABASE_DATABASE=fabricexplorer

      - LOG_CONSOLE_STDOUT=true
      - DISCOVERY_AS_LOCALHOST=false
      - PORT=${PORT:-8080}
    volumes:
      - ./config.json:/opt/explorer/app/platform/fabric/config.json
      - ./connection-profile:/opt/explorer/app/platform/fabric/connection-profile
      - /home/songzehao/fabric/organizations:/tmp/crypto
      - walletstore:/opt/explorer/wallet
    ports:
      - ${PORT:-8080}:${PORT:-8080}
    depends_on:
      explorerdb.mynetwork.com:
        condition: service_healthy

三、配置区块链浏览器

创建配置文件config.json：

vim /home/songzehao/fabric/explorer/config.json
1

内容如下：

{
    "network-configs": {
        "fabric_dev": {
            "name": "Fabric for dev",
            "profile": "./connection-profile/fabric_dev.json"
        }
    },
    "license": "Apache-2.0"
}

继续配置节点证书相关fabric_dev.json：

vim /home/songzehao/fabric/explorer/connection-profile/fabric_dev.json
1

内容如下：

{
    "name": "fabric_dev",
    "version": "1.0.0",
    "client": {
        "tlsEnable": true,
        "adminCredential": {
            "id": "exploreradmin",
            "password": "exploreradminpw"
        },
        "enableAuthentication": false,
        "organization": "Org1MSP",
        "connection": {
            "timeout": {

                    "endorser": "300"
                },
                "orderer": "300"
            }
        }
    },
    "channels": {
        "channel1": {
            "peers": {
                "peer0.org1.example.com": {}
            }
        }
    },
    "organizations": {
        "Org1MSP": {
            "mspid": "Org1MSP",
            "adminPrivateKey": {
                "path": "/tmp/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp/keystore/priv_sk"
            },
            "peers": ["peer0.org1.example.com"],
            "signedCert": {
                "path": "/tmp/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp/signcerts/cert.pem"
            }
        }
    },
    "peers": {
        "peer0.org1.example.com": {
            "tlsCACerts": {
                "path": "/tmp/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt"
            },
            "url": "grpcs://192.168.3.128:7051"

四、启动区块链浏览器

$ cd /home/songzehao/fabric/explorer && docker-compose -f docker-compose.yaml up -d
Creating network "fabric_dev" with the default driver
Creating explorerdb.mynetwork.com ... done
Creating explorer.mynetwork.com   ... done

启动完成，查看docker容器：

$ docker ps
CONTAINER ID   IMAGE                                            COMMAND                  CREATED          STATUS                    PORTS                                       NAMES
