 #### 步骤三：Systemd 服务配置
-创建系统服务文件 `/etc/systemd/system/work-hours-tracker.service`：
+仓库内已带与线上运行一致的单元文件 `server/work-hours-tracker.service`，拷贝后启用即可：
+```bash
+cp server/work-hours-tracker.service /etc/systemd/system/work-hours-tracker.service
+# 部署路径不同时，先修改单元文件里的 WorkingDirectory 再 daemon-reload
+systemctl daemon-reload
+systemctl enable --now work-hours-tracker.service
+```
+
+单元文件关键内容（端口固定 9522：localStorage 按 origin 隔离，换端口 = 换 origin，
+已有打卡数据会看不见，勿改）：
