再给你个php的配置教程.我就是根据这个配置的.
先从各官方网站下了APACHE2.050、PHP5、MYSQL4.0.20、PHPMYADMIN2.57apache_2.0.50-win32-x86-no_ssl.msi
php-5.0.0-Win32.zip
mysql-4.0.20d-win.zip
phpMyAdmin-2.5.7.zip操作系统 win2003 系统盘为: D盘第一步: 安装apache 并配置支持PHP点击安装文件apache_2.0.50-win32-x86-no_ssl.msi
将apache安装在 D:\apache2 目录（随自己喜好）下
将php-5.0.0-Win32.zip 里内容解压到 D:\php 里
找到 php目录里的 php.ini-dist 重命名为 php.ini 并拷到 windows目录里(win2k 里为winnt)
如我的php.ini是拷到 D:\windows目录
再将php目录里的 php5ts.dll,libmysql.dll 拷到 系统目录(system/system32) 如我的是D:\windows\system里配置apache里的httpd.conf
打开 D:\Apache2\conf\httpd.conf 这个文件
找到 AddDefaultCharset ISO-8859-1 将其改为 AddDefaultCharset GB2312 （让默认语言编码为简体中文）
找到 DocumentRoot "D:/Apache2/htdocs" 将其改为你的WEB目录（可不改）如我的为 DocumentRoot "D:/website"
找到 DirectoryIndex index.html index.html.var 在后面加入 index.htm index.php选择安装模式： 模块化模式安装 或 CGI模式安装 （选一样即可）--------------模块化安装配置------------------------------------
找到 #LoadModule ssl_module modules/mod_ssl.so 这行，在此行后加入一行
LoadModule php5_module d:/php/php5apache2.dll
其中d:/php/php5apache2.dll 为你php目录中php5apache2.dll所在的位置
找到 AddType application/x-gzip .gz .tgz 这行，在此行后加入一行
AddType application/x-httpd-php .php
-----------------------------------------------------------------------------CGI安装配置--------------------------------------
找到 AddType application/x-gzip .gz .tgz 这行，加入如下即可
ScriptAlias /php/ "d:/php/"
AddType application/x-httpd-php .php
Action application/x-httpd-php "/php/php-cgi.exe"
---------------------------------------------------------------此时PHP环境基本已经配置成功
在WEB根目录（如我的D:\website）里建一个名为test.php的文件内容如下
<? echo phpinfo(); ?>
重新启动apache服务
用浏览器打开 http://localhost/test.php
如果可以看到php配置输出信息就OK了第二步 安装mysql将mysql安装到指定目录，如我的是d:/mysql 如下载的是非安装的mysql压缩包，直接解压到指定目录就可以了
然后点击D:\mysql\bin\winmysqladmin.exe这个文件 其中D:\mysql是你的mysql安装目录
输入winmysqladmin的初始用户、密码 （注：这不是mysql里的用户、密码）随便填不必在意
确定之后你的右下角任务的启动栏会出现一个红绿灯的图标，红灯亮代表服务停止，绿灯亮代表服务正常，左击这个图标->winnt->install the service 安装此服务
再左击这个图标->winnt->start the service 启动mysql服务修改mysql数据库的root密码
用cmd进入命今行模式输入如下命令: ( 注: d:\mysql 为mysql安装目录)
cd d:\mysql\bin
mysqladmin -u root -p password 123456
回车出现
Enter password: ( 注:这是叫你输入原密码. 刚安装时密码为空,所以直接回车即可)
此时mysql 中账号 root 的密码 被改为 123456 安装完毕三、配置php.ini并测试mysql（php.ini为 d:\windows下的 php.ini）找到extension_dir = "./" 改为 extension_dir = "d:/php/ext"
找到
;extension=php_mysql.dll
将';'去掉改为
extension=php_mysql.dll
找到
;session.save_path = "/tmp"
将';'去掉 设置你保存session的目录，如
session.save_path = "D:/php/session_temp";重启apache服务
在Web根目录下（如 D:\website）建立testdb.php文件内容如下：
<?php
$link=mysql_connect('localhost','root','123456');
if(!$link) echo "fail";
else echo "success";
mysql_close();
?>
用浏览器打开http://localhost/testdb.php 如果输出success就OK了四、phpmyadmin的安装配置将phpMyAdmin-2.5.7.zip解压到WEB根目录中去，重命名文件夹为phpmyadmin或其它
打开phpmyadmin 目录中的 config.inc.php
找到
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '123456';
分别填上你mysql的用户和密码即可如不是本地使用，最好加上验证新
以上各位告诉我的方法都是windows下的。我想请教大家能否提供Linux下的解决方法。
