# 整体部署：构建并部署 zMainPage（含子模块）+ zTools2（后端）到生产环境。
#
# 生产拓扑：
#   Apache(:80) -> 静态文件 /var/www/html（zMainPage 构建产物）
#              -> 反代 /api、/pdf、/pdf-admin、/ws 等到 zTools2(127.0.0.1:6867)
#   zTools2(127.0.0.1:6867) -> MySQL(3306) + uploads/ 磁盘
#
# 前提：zMainPage 与 zTools2 在同一主机（zMainPage 父项目，zTools2 同级目录）。
# 用法：./deploy.sh [--no-restart]  （--no-restart 仅更新文件不重启 zTools2）
