基于blocksout搭建区块浏览器

下载开源项目：https://github.com/blockscout/blockscout

 

docker部署文档：https://docs.blockscout.com/setup/deployment/docker-compose-deployment

 

这样就可以了：

cd ./docker-compose
docker-compose up --build -d

参考文档：

backend参数：https://docs.blockscout.com/setup/env-variables/backend-env-variables

frontend参数：https://docs.blockscout.com/setup/env-variables/frontend-common-envs

参数修改：

我现在可以更完整地告诉您需要修改的文件：

1. 主配置文件 docker-compose/docker-compose.yml

     environment:
         ETHEREUM_JSONRPC_HTTP_URL: http://192.168.31.213:8545/
         ETHEREUM_JSONRPC_TRACE_URL: http://192.168.31.213:8545/
         ETHEREUM_JSONRPC_WS_URL: ws://192.168.31.213:8546/
         CHAIN_ID: '15656'
         NETWORK: 'OSC'
         SUBNETWORK: 'TESTNET'

2. 环境变量文件 docker-compose/envs/common-blockscout.env

需要修改的关键配置：

# 链的类型配置
   ETHEREUM_JSONRPC_VARIANT=geth  # 如果您使用的是 geth 客户端，保持不变
   
   # 数据库配置（已经配置好，一般不需要修改）
   DATABASE_URL=postgresql://blockscout:ceWb1MeLBEeOIfk65gU8EjF8@db:5432/blockscout
   
   # 币种配置
   COIN_NAME=OSC  # 设置为您的币种名称
   COIN=OSC       # 设置为您的币种符号
   
   # API 配置
   API_V2_ENABLED=true  # 启用 V2 API
   
   # 市场数据配置
   DISABLE_MARKET=true  # 如果不需要显示市场数据，保持为 true
   
   # 性能配置
   POOL_SIZE=80        # 数据库连接池大小
   POOL_SIZE_API=10    # API 数据库连接池大小
   
   # 心跳超时
   HEART_BEAT_TIMEOUT=30

3. 前端环境变量文件 docker-compose/envs/common-frontend.env

需要修改的配置：

NEXT_PUBLIC_API_HOST=192.168.31.215
NEXT_PUBLIC_API_PROTOCOL=http
NEXT_PUBLIC_STATS_API_HOST=http://192.168.31.215:8080
NEXT_PUBLIC_NETWORK_NAME=Octobus smart chain
NEXT_PUBLIC_NETWORK_SHORT_NAME=Octobus
NEXT_PUBLIC_NETWORK_ID=1029
NEXT_PUBLIC_NETWORK_CURRENCY_NAME=ONB
NEXT_PUBLIC_NETWORK_CURRENCY_SYMBOL=ONB
NEXT_PUBLIC_NETWORK_CURRENCY_DECIMALS=18
NEXT_PUBLIC_API_BASE_PATH=/
NEXT_PUBLIC_APP_HOST=192.168.31.215
NEXT_PUBLIC_APP_PROTOCOL=http
NEXT_PUBLIC_HOMEPAGE_CHARTS=['daily_txs']
NEXT_PUBLIC_VISUALIZE_API_HOST=http://192.168.31.215:8081
NEXT_PUBLIC_IS_TESTNET=true
NEXT_PUBLIC_API_WEBSOCKET_PROTOCOL=ws
NEXT_PUBLIC_API_SPEC_URL=https://raw.githubusercontent.com/blockscout/blockscout-api-v2-swagger/main/swagger.yaml
# Required to enable blockchain interaction
# NEXT_PUBLIC_WALLET_CONNECT_PROJECT_ID=

  注意host需要配置成docker容器内部可以访问的变量

  4. nginx配置文件 docker-compose/proxy/default.conf.template

允许跨域

server {
    listen       80;
    server_name  localhost;
    proxy_http_version 1.1;
    add_header 'Access-Control-Allow-Origin' '*' always;
    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PUT, DELETE, PATCH' always;
    add_header 'Access-Control-Allow-Headers' 'DNT,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization,x-csrf-token' always;

    location ~ ^/(api(?!-docs$)|socket|sitemap.xml|auth/auth0|auth/auth0/callback|auth/logout) {
        proxy_pass            ${BACK_PROXY_PASS};
        proxy_http_version    1.1;
        proxy_set_header      Host "$host";
        proxy_set_header      X-Real-IP "$remote_addr";
        proxy_set_header      X-Forwarded-For "$proxy_add_x_forwarded_for";
        proxy_set_header      X-Forwarded-Proto "$scheme";
        proxy_set_header      Upgrade "$http_upgrade";
        proxy_set_header      Connection $connection_upgrade;
        proxy_cache_bypass    $http_upgrade;

        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Allow-Origin' '*' always;
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PUT, DELETE, PATCH' always;
            add_header 'Access-Control-Allow-Headers' 'DNT,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization,x-csrf-token' always;
            add_header 'Access-Control-Max-Age' 1728000;
            add_header 'Content-Type' 'text/plain charset=UTF-8';
            add_header 'Content-Length' 0;
            return 204;
        }
    }

允许跨域需要加上，不然会报错：

    add_header 'Access-Control-Allow-Origin' '*' always;
      add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PUT, DELETE, PATCH' always;
      add_header 'Access-Control-Allow-Headers' 'DNT,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization,x-csrf-token' always;

 

修改这些文件后，需要重启服务：

docker-compose down
docker-compose up -d

非常简单，一键部署
