+### 宝塔面板手动部署

+先下载并解压签名 Release；项目目录必须指向同时包含 `app.jar`、`VERSION`、`public/` 和 `ops/` 的目录。
+推荐采用版本目录加 `current` 软链接：
+
+```bash

+RELEASE_ROOT=/www/wwwroot/kaidi/releases/$VERSION
+sudo install -d -o root -g kaidi -m 0750 "$RELEASE_ROOT"

+
+| 字段 | 值 |
+| --- | --- |
+| 项目类型 | Spring Boot |
+| 项目路径 | `/www/wwwroot/kaidi/current` |
+| 项目名称 | `kaidi-finance` |
+| 项目 JDK | JDK 17 |
+| 项目启动命令 | `/www/wwwroot/kaidi/current/ops/baota-start.sh` |
+| 启动用户 | `kaidi`，禁止使用 root |
+| 项目端口 | `18080` |
+| 绑定域名 | 实际业务域名，例如 `fi.awaioi.com` |
+| 后端路由 | `/` |
+| 前端资源 | 留空，由 Spring Boot 提供 `public/` |
+| 进程守护 | 开启 |
+| 项目意外重启 | 勾选 |
+
+环境变量按 `ops/baota.env.example` 填入宝塔。已完成安装的服务器必须沿用
+`/var/lib/kaidi/setup/application.env` 中的 `DB_URL`、`DB_USERNAME`、`DB_PASSWORD`，以及
+`/etc/kaidi/kaidi.env` 中的 `FIELD_ENCRYPTION_KEY`；不要生成新的字段加密密钥。HTTP Preview 使用
+`SESSION_COOKIE_SECURE=false`，切换到 HTTPS 后改为 `true`。宝塔模式固定设置
+`FINANCE_UPDATE_ENABLED=false`，版本更新通过上传新目录、切换 `current`、重启项目完成。
+
+启用宝塔守护前停用原 systemd 进程，避免两个进程管理器反复争用端口或互相重启：
+
+```bash
+sudo systemctl disable --now kaidi-update.path kaidi-finance.service
+sudo systemctl stop kaidi-update.service
+```
+
+启动后在服务器验证 Java 上游，再配置域名反向代理：
