部署指南

环境准备

系统要求

Linux (Ubuntu 22.04+ / Debian 12+ 推荐)
2+ CPU 核心（启用独立 Worker 建议 4+）
4GB+ 内存
50GB+ 磁盘空间

依赖安装

# Ubuntu/Debian
sudo apt update
sudo apt install -y \
    build-essential \
    pkg-config \
    libssl-dev \
    libpq-dev \
    cmake \
    nasm \
    libjpeg-dev \
    libpng-dev \
    libwebp-dev

# 安装 Rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source ~/.cargo/env

# 初始化数据库会用到 psql（建议安装 PostgreSQL client）
sudo apt install -y postgresql-client

# 安装 Node.js (前端构建)
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
sudo apt install -y nodejs

本地开发

1. 启动数据库服务

# 使用 Docker Compose 启动 PostgreSQL 和 Redis
docker-compose -f docker/docker-compose.dev.yml up -d

docker/docker-compose.dev.yml:

version: '3.8'

services:
  postgres:
    image: postgres:16-alpine
    environment:
      POSTGRES_USER: imageforge
      POSTGRES_PASSWORD: devpassword
      POSTGRES_DB: imageforge
    ports:
      - "5432:5432"
    volumes:
      - postgres_data:/var/lib/postgresql/data

  redis:
    image: redis:7-alpine
    ports:
      - "6379:6379"
    volumes:
      - redis_data:/data

  # 可选：MinIO（S3 兼容，本地开发更接近生产）
  # minio:
  #   image: minio/minio:RELEASE.2024-01-28T20-20-01Z
  #   command: server /data --console-address ":9001"
  #   environment:
  #     MINIO_ROOT_USER: minioadmin
  #     MINIO_ROOT_PASSWORD: minioadmin
  #   ports:
  #     - "9000:9000"
  #     - "9001:9001"
  #   volumes:
  #     - minio_data:/data

volumes:
  postgres_data:
  redis_data:
  minio_data:

2. 配置环境变量

cp .env.example .env

.env.example:

# 运行模式：建议将 API 与 Worker 分开运行
IMAGEFORGE_ROLE=api # api | worker

# 服务配置
HOST=0.0.0.0
PORT=8080
PUBLIC_BASE_URL=http://localhost:8080
RUST_LOG=info,imageforge=debug

# 数据库
DATABASE_URL=postgres://imageforge:devpassword@localhost:5432/imageforge

# Redis
REDIS_URL=redis://localhost:6379

# JWT（网站/管理后台）
JWT_SECRET=your-super-secret-key-change-in-production
JWT_EXPIRY_HOURS=168

# API Key
API_KEY_PEPPER=please-change-this-in-production

# 存储（生产建议 S3/MinIO + 预签名 URL）
STORAGE_TYPE=local  # local | s3
STORAGE_PATH=./uploads
# 预签名下载链接过期（分钟）
SIGNED_URL_TTL_MINUTES=60

# S3 配置（如果使用 S3/MinIO）
# S3_ENDPOINT=http://localhost:9000
# S3_BUCKET=your-bucket
# S3_REGION=us-east-1
# S3_ACCESS_KEY=xxx
# S3_SECRET_KEY=xxx

# 计费（已确认：Stripe）
BILLING_PROVIDER=stripe
STRIPE_SECRET_KEY=sk_test_xxx
STRIPE_WEBHOOK_SECRET=whsec_xxx

# 限制（默认值；最终以套餐/用户覆盖为准）
ALLOW_ANONYMOUS_UPLOAD=true
ANON_MAX_FILE_SIZE_MB=5
ANON_MAX_FILES_PER_BATCH=5
ANON_DAILY_UNITS=10
MAX_IMAGE_PIXELS=40000000
IDEMPOTENCY_TTL_HOURS=24

# 结果保留（匿名默认；登录用户按套餐 retention_days）
ANON_RETENTION_HOURS=24

# 管理员初始账户
ADMIN_EMAIL=admin@example.com
ADMIN_PASSWORD=changeme123

3. 初始化数据库

# 运行首期迁移（可重复执行）
psql "$DATABASE_URL" -f migrations/001_init.sql

4. 启动开发服务器

# 后端 API (热重载)
cargo install cargo-watch
IMAGEFORGE_ROLE=api cargo watch -x run

# 后端 Worker（另一个终端，处理异步/批量任务）
IMAGEFORGE_ROLE=worker cargo watch -x run

# 前端 (另一个终端)
cd frontend
npm install
npm run dev

5. Stripe Webhook 本地调试（可选）

本地调试 Stripe 订阅/支付状态，通常需要将 Stripe Webhook 转发到本机：

# 1) 安装并登录 Stripe CLI（按官方文档）
# 2) 监听并转发到你的后端回调地址
stripe listen --forward-to http://localhost:8080/api/v1/webhooks/stripe

# CLI 会输出一个 whsec_...，写入 .env 的 STRIPE_WEBHOOK_SECRET

生产部署

注意：以下内容为生产部署模板示例；仓库当前首期仅提供开发用 docker/docker-compose.dev.yml，生产 compose/Dockerfile/nginx/k8s 等可在开工阶段按需落地并调整。

部署步骤

# 1. 创建 .env 文件
cat > .env << EOF
DB_PASSWORD=your-secure-db-password
JWT_SECRET=your-very-long-random-jwt-secret-at-least-32-chars
STRIPE_SECRET_KEY=sk_live_xxx
STRIPE_WEBHOOK_SECRET=whsec_xxx
EOF

# 2. 获取 SSL 证书
sudo certbot certonly --standalone -d your-domain.com

# 3. 构建并启动
docker-compose -f docker/docker-compose.prod.yml up -d --build

# 4. 查看日志
docker-compose -f docker/docker-compose.prod.yml logs -f api

监控与日志

Prometheus 指标

应用暴露 /metrics 端点：

// 在代码中添加指标
use prometheus::{Counter, Histogram};

lazy_static! {
    static ref COMPRESSION_REQUESTS: Counter = Counter::new(
        "imageforge_compression_requests_total",
        "Total number of compression requests"
    ).unwrap();

    static ref COMPRESSION_DURATION: Histogram = Histogram::with_opts(
        HistogramOpts::new(
            "imageforge_compression_duration_seconds",
            "Time spent compressing images"
        )
    ).unwrap();
}

Grafana 仪表板

监控项目：

请求量 / QPS
响应时间 P50/P95/P99
错误率
压缩任务队列长度
CPU / 内存使用率
磁盘使用率

日志聚合

使用 ELK Stack 或 Loki：

# docker-compose 添加 Loki
loki:
  image: grafana/loki:2.9.0
  ports:
    - "3100:3100"
  command: -config.file=/etc/loki/local-config.yaml

promtail:
  image: grafana/promtail:2.9.0
  volumes:
    - /var/log:/var/log
    - ./promtail-config.yml:/etc/promtail/config.yml
  command: -config.file=/etc/promtail/config.yml

备份策略

数据库备份

#!/bin/bash
# backup.sh

DATE=$(date +%Y%m%d_%H%M%S)
BACKUP_DIR=/backups

# PostgreSQL 备份
docker exec postgres pg_dump -U imageforge imageforge | gzip > $BACKUP_DIR/db_$DATE.sql.gz

# 保留最近 7 天的备份
find $BACKUP_DIR -name "db_*.sql.gz" -mtime +7 -delete

# 可选：上传到 S3
# aws s3 cp $BACKUP_DIR/db_$DATE.sql.gz s3://your-bucket/backups/

添加到 crontab：

0 3 * * * /path/to/backup.sh

上传文件备份

如果使用本地存储，定期同步到 S3：

aws s3 sync /app/uploads s3://your-bucket/uploads --delete

故障排查

常见问题

1. 数据库连接失败

# 检查 PostgreSQL 状态
docker-compose logs postgres

# 测试连接
docker exec -it postgres psql -U imageforge -d imageforge -c "SELECT 1"

2. 压缩失败

# 检查应用日志
docker-compose logs api | grep ERROR
docker-compose logs worker | grep ERROR

# 检查磁盘空间
df -h

3. 内存不足

# 查看内存使用
docker stats

# 调整容器内存限制

4. 上传超时

# 检查 Nginx 配置
# client_max_body_size 和 proxy_read_timeout

健康检查端点

GET /health

  "status": "healthy",
  "database": "connected",
  "redis": "connected",
  "storage": "available",
