php 连接mysql失败

hinswhale 2012-04-28 10:07:36

复制以下代码粘贴至conn_mysql.php文件，把“你的密码”改成你的mysql密码
<?php
$connection = mysql_connect ("localhost","root","你的密码");
mysql_select_db ("mysql");
if($connection){
echo "<script>alert('数据库连接正常');</script>";
}
else{
echo "<script>alert('数据库连接失败,请检mysqle服务是否启动');</script>";
}
?>

在浏览器里输入：http://127.0.0.1/conn_mysql.php后失败
显示：Not Found

The requested URL /conn_mysql.php was not found on this server.
这是怎么回事，本人是菜鸟，求大侠们知道。

检查你的php环境和，先检查你的WEB服务器环境吧如果是Apache的话检查配置是否正常，监测方法：尝试输出 <? phpinfo();?>

根目录新建个文件

<?php
phpinfo();
?>

然后看看是否正常

这是error.log内容，在浏览器里输入：http://127.0.0.1/conn_mysql.php后网页还是打不开
