Hyperledger Explorer是一個簡單、強大、易於使用、維護良好的開源工具，可以瀏覽底層區塊鏈網絡上的活動。 項目地址：https://github.com/hyperledger/blockchain-explorer
編寫 fabric 網絡連接配置文件
該連接配置文件要根據我們的網絡拓撲結構進行編寫。

編寫 config.json 配置文件
這個配置文件用來指定 fabric 網絡連接配置文件的路徑。
{
"network-configs": {
"prod-network": {
"name": "Prod Network",
"profile": "./connection-profile/org1ProdNetworkConnection.json"
}
},
"license": "Apache-2.0"
}
編寫 docker-compose 文件
docker-compose-explorer.yaml:
version: '2.0'
volumes:
pgdata:
walletstore:
services:
explorerdb.mynetwork.com:
image: hyperledger/explorer-db:latest
container_name: explorerdb.mynetwork.com
hostname: explorerdb.mynetwork.com
ports:
- 5432:5432
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
explorer.mynetwork.com:
image: hyperledger/explorer:latest
container_name: explorer.mynetwork.com
hostname: explorer.mynetwork.com
ports:
- 9090:8080
extra_hosts:
- "explorerdb.mynetwork.com:192.168.0.105"
- "orderer0.example.com:192.168.0.105"
- "orderer1.example.com:192.168.0.105"
- "orderer2.example.com:192.168.0.105"

- "peer0.org2.example.com:192.168.0.110"
- "peer1.org2.example.com:192.168.0.110"
environment:
- DATABASE_HOST=explorerdb.mynetwork.com
- DATABASE_DATABASE=fabricexplorer
- DATABASE_USERNAME=hppoc
- DATABASE_PASSWD=password
- LOG_LEVEL_APP=debug
- LOG_LEVEL_DB=info
- LOG_LEVEL_CONSOLE=debug
- LOG_CONSOLE_STDOUT=true
- DISCOVERY_AS_LOCALHOST=false
volumes:
- ./config.json:/opt/explorer/app/platform/fabric/config.json
- ./connection-profile:/opt/explorer/app/platform/fabric/connection-profile
- ../crypto-config:/tmp/crypto
- walletstore:/opt/explorer/wallet
depends_on:
explorerdb.mynetwork.com:
condition: service_healthy
這些文件都準備好了後目錄結構如下：
hyperledger-explorer/
├── config.json
├── connection-profile
│ └── org1ProdNetworkConnection.json
└── docker-compose-explorer.yaml
啓動 Hyperledger Explorer：
docker-compose -f docker-compose-explorer.yaml up -d
清理（不刪除持久性數據）：
docker-compose -f docker-compose-explorer.yaml down
徹底清理：
docker-compose -f docker-compose-explorer.yaml down -v
啓動後訪問 http://localhost:9090/:
