一键搭建轻量论坛脚本(xiuno)

一键搭建一个轻量级论坛脚本 ：

bash <(curl -sL https://fastyw.com/wp-content/uploads/2022/12/bbs.sh)

代码分析：

使用了 php:7.2-apache 作为基础镜像

安装了 pdo-mysql 拓展

源码采用 githab 上开源代码

docker-compose 编排了 2 个 docker

为了安全外部只暴露了一个 80 端口

整个项目容器化，方便使用和迁移

数据目录储存在 /data 目录下

如果需要备份，可以备份 /data 目录

脚本源代码 ：

#!/bin/bash
# Author: 有人说我白

RED="\033[31m"      # Error message
GREEN="\033[32m"    # Success message
YELLOW="\033[33m"   # Warning message
BLUE="\033[36m"     # Info message
PLAIN='\033[0m'
