+# 美国版服务器采购配置清单
+
+> 适用范围：美国版 Web 管理端 + UniApp 员工端  
+> 技术栈：.NET 8 API + MySQL + React 静态站  
+> 原则：独立环境，不与泰额版共用资源
+
+---
+
+## 1. 环境定位
+
+| 项 | 说明 |
+|---|---|
+| 用户区域 | 美国 |
+| 后端 | `Yi.Abp.Web`（.NET 8 + SqlSugar） |
+| 前端 | React 18 + Vite 静态托管 |
+| 移动端 | UniApp（调用同一套 API） |
+| 文件存储现状 | 本地磁盘（图片、批量导入模板） |
+| Redis | 配置存在，当前默认关闭 |
+
+---
+
+## 2. 必买清单
+
+| 序号 | 项 | 建议规格 | 备注 |
+|---|---|---|---|
+| 1 | 云厂商 + 地域 | AWS / Azure / GCP，**美东或美西** | 就近访问、合规 |
+| 2 | 应用服务器 | **4 核 8G**，系统盘 **40～80G SSD** ×1（建议预留扩到 2 台） | 运行 API |
+| 3 | MySQL（RDS） | **2～4 核 / 4～8G 内存**，存储 **50～100G SSD** | 开启自动备份 7～30 天 |
+| 4 | 负载均衡 / 公网 | SLB 或云 LB；带宽 **5～20Mbps** 或按量 | API 对外入口 |
+| 5 | 域名 + SSL | 1 个主域名；建议 `api.` / `admin.` 子域 | HTTPS 必需 |
+| 6 | 反向代理 | Nginx（可与 API 同机） | 反代 API + 托管 React 静态文件 |
+| 7 | 安全组 / 防火墙 | 仅开放 80/443；SSH 限 IP | 数据库不对公网开放 |
+| 8 | 备份 + 监控 | RDS 自动备份；CPU / 内存 / 磁盘 / 5xx 告警 | 云厂商自带即可 |
+
+---
+
+## 3. 建议购买（正式上线）
+
+| 序号 | 项 | 建议规格 | 备注 |
+|---|---|---|---|
+| 9 | 对象存储 S3 / OSS | **50～100G** + 按量流出 | 图片、导入文件；后期多实例必备 |
+| 10 | CDN（可选） | 绑定静态站 / 图片桶 | App 拉图更快 |
+
+---
+
+## 4. 可暂缓
+
+| 项 | 说明 |
+|---|---|
+| Redis | 当前关闭；验证码 / 多实例后再上，**1G** 即可 |
+| 第二台 API | 有滚动发布 / 高可用需求再买 |
+| 独立日志 / 消息队列 | 当前架构暂不需要 |
+| 独立邮件服务 | 已有 Office365 SMTP 可继续使用 |
+
+---
+
+## 5. OSS 结论
+
+| 阶段 | 是否购买 | 说明 |
+|---|---|---|
+| 内测 / 单机试跑 | 可不买 | 本地盘可用 |
+| 正式上线 | **建议购买** | 换机不丢文件，方便横向扩容 |
+| 容量建议 | 50～100G | 按租户 / 业务前缀隔离目录 |
+
+未切 OSS 前，本地目录参考：
+
+- 图片：`/www/wwwroot/FoodLabelingManagementUs/picture`
+- 批量导入模板：`/www/wwwroot/FoodLabelingManagementUs/batchImportOfFiles`
+
+未上 OSS 时，建议系统盘 **≥ 80G**，避免图片打满磁盘。
+
+> 说明：购买 OSS 后需改造上传逻辑（如 `PictureAppService`）；可先开桶，代码分迭代切换。
+
+---
+
+## 6. 软件与部署要求
+
+| 项 | 内容 |
+|---|---|
+| 运行时 | .NET 8 Runtime、Nginx |
+| API | `Yi.Abp.Web` |
+| 前端 | React Vite 构建产物由 Nginx 托管 |
+| 数据库访问 | 仅 VPC 内网，不对公网 |
+| 发布方式 | 建议预留第二台机器做滚动发布 |
+
+---
+
+## 7. 一页勾选版
+
+```
+美国版生产环境
+□ 美区 VPC / 账号
+□ ECS/VM  4C8G ×1（系统盘 80G）
+□ MySQL RDS  2～4C / 4～8G / 50～100G + 自动备份
+□ SLB + 公网带宽
+□ 域名 + SSL 证书
+□ Nginx（API 反代 + Web 静态）
+□ 安全组：80/443；RDS 仅内网
+□ 监控告警
+□ S3/OSS 50～100G（正式建议勾选）
+□（可选）Redis 1G
+□（可选）CDN
+□（可选）第二台 4C8G（高可用）
+```
+
+---
+
+## 8. 预算量级（仅供参考）
+
+| 场景 | 粗算月费 |
+|---|---|
+| 起步（1 台 API + RDS + 小容量 S3） | 约 **$80～200 / 月** |
+| 扩容方向 | 优先加 RDS 规格，其次加第二台 API；OSS 按量扩容 |
+
+---
+
+## 9. 采购顺序建议
+
+1. 确定云厂商与美区地域  
+2. 购买 RDS + 应用机 + 域名证书  
+3. 同步开通 S3/OSS 桶（即使第一期仍写本地）  
+4. 跑通发布后再评估 Redis、第二台 API、CDN
