Go Vehicle Gateway Native Deployment

本目录用于 ECS 原生部署。当前 goal 后续不再使用 Docker/Portainer 作为 Go 接入链路的部署方式。

Services

systemd unit	Binary	Purpose
`lingniu-go-gateway.service`	`gateway`	GB32960 TCP `32960`、JT808 TCP `808`、宇通 MQTT 接入，写 Kafka RAW/unified
`lingniu-go-history-writer.service`	`history-writer`	消费 RAW topic，写 TDengine `raw_frames` 和核心时序表
`lingniu-go-stat-writer.service`	`stat-writer`	消费 RAW topic，写 MySQL `vehicle_daily_metric`
`lingniu-go-realtime-api.service`	`realtime-api`	消费 unified topic，写 Redis，并提供 realtime/raw/stat 查询 API

Build

在开发机或 CI 上构建 Linux amd64 二进制：

cd go/vehicle-gateway
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -trimpath -ldflags='-s -w' -o /tmp/lingniu-go-native/gateway ./cmd/gateway
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -trimpath -ldflags='-s -w' -o /tmp/lingniu-go-native/history-writer ./cmd/history-writer
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -trimpath -ldflags='-s -w' -o /tmp/lingniu-go-native/stat-writer ./cmd/stat-writer
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -trimpath -ldflags='-s -w' -o /tmp/lingniu-go-native/realtime-api ./cmd/realtime-api

Cutover Notes

先上传二进制到新 release 目录并更新 current symlink。
从现有生产 env 生成四个 systemd 专用 env 文件；不要把密钥写入仓库。
停止旧 Docker Go 容器或 Java 容器，释放 808、32960、20210。
执行：

systemctl daemon-reload
systemctl enable lingniu-go-gateway lingniu-go-history-writer lingniu-go-stat-writer lingniu-go-realtime-api
systemctl restart lingniu-go-gateway lingniu-go-history-writer lingniu-go-stat-writer lingniu-go-realtime-api

Verification

systemctl is-active lingniu-go-gateway lingniu-go-history-writer lingniu-go-stat-writer lingniu-go-realtime-api
ss -lntp | egrep ':(808|32960|20210)\b'
journalctl -u lingniu-go-gateway --since '5 minutes ago' --no-pager
curl -sS 'http://127.0.0.1:20210/api/history/raw-frames?protocol=JT808&limit=1'
curl -sS 'http://127.0.0.1:20210/api/history/raw-frames?protocol=GB32960&limit=1'
