+# Nginx 配置说明
+
+## 配置文件
+
+- `nginx.conf` - 主配置文件
+
+## 功能特性
+
+1. **前端静态文件服务** - 服务 React 构建后的静态文件
+2. **API 代理** - 将 `/api` 请求代理到后端服务器 (localhost:3001)
+3. **SPA 路由支持** - 支持 React Router 的客户端路由
+4. **静态资源缓存** - 优化静态资源加载性能
+5. **健康检查** - `/health` 端点用于健康检查
+
+## 部署步骤
+
+### 1. 构建前端
+
+```bash
+cd frontend
+npm run build
+```
+
+构建输出在 `frontend/dist/` 目录
+
+### 2. 配置 Nginx
+
+编辑 `nginx.conf` 文件，修改以下配置：
+
+- `server_name`: 改为您的域名
+- `root`: 改为前端构建文件的绝对路径
+- `upstream backend`: 确保后端服务器地址正确
+
+### 3. 安装配置文件
+
+```bash
+# 复制配置文件到 nginx 配置目录
+sudo cp nginx/nginx.conf /etc/nginx/sites-available/ai-learning-platform
+
+# 创建符号链接
+sudo ln -s /etc/nginx/sites-available/ai-learning-platform /etc/nginx/sites-enabled/
+
+# 测试配置
+sudo nginx -t
+
+# 重新加载 nginx
+sudo systemctl reload nginx
+```
+
+### 4. 启动后端服务
+
+确保后端服务在 3001 端口运行：
+
+```bash
+cd backend
+npm run build
+npm start
+```
+
+或者使用 PM2 管理：
+
+```bash
+pm2 start backend/dist/index.js --name ai-learning-backend
+```
+
+## 配置说明
+
+### 前端路径
+
+默认配置假设前端构建文件在：
+```
+/var/www/ai-learning-platform/frontend/dist
+```
+
+请根据实际部署路径修改 `root` 指令。
+
+### 后端代理
+
+API 请求会被代理到：
+```
+http://localhost:3001
+```
+
+如果需要修改，编辑 `upstream backend` 部分。
+
+### 静态资源缓存
+
+静态资源（JS、CSS、图片等）会缓存 1 年，提高性能。
+
+### SPA 路由支持
+
+`try_files $uri $uri/ /index.html;` 确保所有路由都返回 `index.html`，支持 React Router。
+
+## HTTPS 配置（可选）
+
+如果需要 HTTPS，取消注释配置文件中的 HTTPS 部分，并：
+
+1. 获取 SSL 证书（Let's Encrypt 免费证书）
+2. 修改证书路径
+3. 重新加载 nginx
+
+### 使用 Let's Encrypt
+
+```bash
+# 安装 certbot
+sudo apt-get install certbot python3-certbot-nginx
+
+# 获取证书
+sudo certbot --nginx -d yourdomain.com
+```
+
+## 性能优化
+
+### Gzip 压缩
+
+在 nginx 主配置文件中添加：
+
+```nginx
+gzip on;
+gzip_vary on;
+gzip_min_length 1024;
+gzip_types text/plain text/css text/xml text/javascript application/x-javascript application/xml+rss application/json;
+```
+
+### 缓存优化
+
+静态资源已配置长期缓存，生产环境建议使用 CDN。
+
+## 监控和日志
+
+- 访问日志：`/var/log/nginx/ai-learning-access.log`
+- 错误日志：`/var/log/nginx/ai-learning-error.log`
+
+## 故障排查
+
+### 检查 nginx 状态
+
+```bash
+sudo systemctl status nginx
+```
+
+### 查看错误日志
+
+```bash
+sudo tail -f /var/log/nginx/ai-learning-error.log
+```
+
+### 测试配置
+
+```bash
+sudo nginx -t
+```
+
+### 重新加载配置
+
+```bash
+sudo systemctl reload nginx
+```
+
+## Docker 部署（可选）
+
+如果使用 Docker，可以创建 `Dockerfile.nginx`：
+
+```dockerfile
+FROM nginx:alpine
+COPY nginx/nginx.conf /etc/nginx/conf.d/default.conf
+COPY frontend/dist /usr/share/nginx/html
+EXPOSE 80
+CMD ["nginx", "-g", "daemon off;"]
+```
