math_cms/deploy.sh

#!/bin/bash
#
# math_cms 统一部署脚本
#
# 用法：
#   ./deploy.sh                    # 部署第一台服务器（主站）
#   ./deploy.sh api                # 部署第二台服务器（API）
#   ./deploy.sh pdf                # 部署第三/四台服务器（PDF Worker）
#   ./deploy.sh all                # 部署当前服务器所有服务
#
# 流程：git pull → 前端构建 → 清 Laravel 缓存 → 重建并重启容器
#
