Windows7环境下Apache连接MySQL提示“连接已重置”的解决办法

win7下手动搭建wamp环境，碰到的几个坑总结下，

1.能正常访问php和html类型文件，但是访问项目文件时老是连接被重置，后来总结是数据库的问题，就写测试用例测试php能否成功调用数据库，

 1 <?php
 2    echo "mysql";
 3 
 4    $mysql_conf = array(
 5     'host'    => '127.0.0.1', 
 6     'db'      => 'drupal628', 
 7     'db_user' => 'root', 
 8     'db_pwd'  => 'admin', 
 9     );
10     $mysql_conn = @mysql_connect($mysql_conf['host'], $mysql_conf['db_user'], $mysql_conf['db_pwd']);
11     if (!$mysql_conn) {
12         echo "失败";
13         die("could not connect to the database:\n" . mysql_error());//诊断连接错误
14     }else{
15         echo "连接成功";
16     }
17 
18 ?>
