+## Docker 部署（推荐）
+
+### docker-compose.yml 示例
+
+```yaml
+version: '3.8'
+
+services:
+  nginx:
+    image: nginx:alpine
+    ports:
+      - "80:80"
+    volumes:

+    volumes:
+      - ./server:/var/www/html
+      - /data:/data          # 数据库挂载到独立目录，避免权限问题
+    environment:
+      - DB_PATH=/data/chat.db    # 通过环境变量覆盖数据库路径
+      - JWT_SECRET=your-secret   # 生产环境务必修改
+      - CHAT_PASSWORD=your-pass  # 生产环境务必修改
+```
+
+### 环境变量说明
+
+| 变量 | 默认值 | 说明 |
+|------|--------|------|
+| `DB_PATH` | `server/chat.db` | SQLite 数据库路径，建议挂载到独立目录 |
+| `JWT_SECRET` | `chat-terminal-secret-key-change-in-production` | JWT 签名密钥，**生产环境必须修改** |
+| `CHAT_PASSWORD` | `admin` | 登录密码，**生产环境必须修改** |
+
