终于加了一个硬盘做了双系统,就是 PHP+Mysql 出现问题了!

硬盘一装的 Windows7
硬盘二 500G 装的 openSUSE,我用 iso 刻录到 U 盘,网络安装的,2 个小时才装好。汗!
然后用的 BCD 在 win7 下编辑的启动项进 openSUSE!

/srv/www/htdocs/phpinfo.php 把 phpinfo.php 移动到这里之后,127.0.0.1/phpinfo.php 访问是空白呢。

phpmyadmin 能够进去管理数据库。

描述得不是很清楚。你是 LAMP 还是 LNMP。双系统跟你这个问题没关系。

你可以放一个内容为

<html>
<head>Test</head>
<body>
<p style="font-weight: bold;color:red;">Test success!</p>
</body>
</html>

的 index.html 在那个位置,然后浏览器打开,看到字就证明是你 php 配置有问题,看不到字就是你网络服务器配置有问题或者服务没启动。
