信不信由你（LAMP+Discuz+Ucenter）

一个脚本实现LAMP+Discuz+Ucenter，信不信由你。灵感来至51cto论坛，一个脚本实现LAMP构建论坛，帖子中错误很多（wenchy回复了也说明了一些问题），在本人反复实验的情况，加以修改，成就了此文，以免将错误继续放大。

#!/bin/bash
# 说明：环境是AS4,这运行脚本之前一定要装上gcc和libxml2-devel。其中httpd-2.2.11.tar.bz2、mysql-5.0.56.tar.gz、php-5.2.9.tar.bz2放在根目录下，Disucz_6.1.0_SC_UTF8.zip、UCenter_1.0.0_SC_UTF8.zip分别放在根目录下discuz和ucenter目录。
