+## 宿主机 Nginx 配置（可选）
+
+如果需要通过宿主机 Nginx 统一管理入口（配置域名、SSL证书），可参考 `deploy/nginx.conf.example`：
+
+```bash
+# 复制配置文件
+sudo cp deploy/nginx.conf.example /etc/nginx/conf.d/ai-service.conf
+
+# 修改配置中的域名
+sudo vim /etc/nginx/conf.d/ai-service.conf
+
+# 测试配置
+sudo nginx -t
+
+# 重载 Nginx
+sudo nginx -s reload
+```
