# 方案 C — 预构建镜像部署（服务器不编译）
## 一、上传
1. 镜像/yubao-app-image.tar → 服务器 /home/project/yubao/deploy/yubao-app-image.tar
2. 部署/deploy/ 内全部 → 服务器 /home/project/yubao/deploy/（覆盖同名脚本）
3. 数据库/（若尚未导入）→ 宝塔导入 email_forecast.sql 到 yubao 库
## 二、服务器首次启动
```bash
cd /home/project/yubao
chmod +x deploy/install-prebuilt-image.sh
bash deploy/install-prebuilt-image.sh
```
## 三、后续更新（只换镜像）
开发机重新 pack-prebuilt-upload.ps1，上传新 tar 后：
bash deploy/update-prebuilt-image.sh deploy/yubao-app-image.tar
## 访问
http://192.168.2.14:30327/login
服务器运行时内存约 1~1.5GB，无需在服务器上编译 Next.js。
