Docker部署php-apache版Moodle实例：本地无响应排查求助

环境配置 #

• mariadb容器（镜像：mariadb:latest）
• php容器（镜像：php:8.3-apache）

Docker容器均显示正常运行，使用nmap扫描localhost结果如下：

Nmap scan report for localhost (127.0.0.1)
Host is up (0.000099s latency).
Not shown: 997 closed tcp ports (conn-refused)
PORT     STATE SERVICE
80/tcp   open  http
443/tcp  open  https
3306/tcp open  mysql

Nmap done: 1 IP address (1 host up) scanned in 0.05 seconds

代码取自Moodle官方仓库的MOODLE_405_STABLE分支，已部署至容器内/var/www/html/moodle路径。

问题现象 #

浏览器访问localhost时，收到提示 127.0.0.1 didn’t send any data.（浏览器原生提示，非Apache错误日志），且Docker容器内无任何错误日志输出。已修改Apache的DocumentRoot与WORKDIR保持一致，但问题仍未解决，缺少错误反馈导致难以定位问题。

Docker配置详情 #

目录结构 #

• 根目录创建moodle目录，存放克隆的仓库代码
• 创建空的moodledata目录，已配置读写权限

docker-compose.yml #
