php无法连接MySQL

ascend1

安装php 5.1.4，MySQL 5.0.24，Apache2，动态连接库方式安装。

写一个php用来测试连接MySQL：

  1 <?php
  2 $link = mysql_connect('localhost', 'root', 'mypassword')
  3
  4    or die('Could not connect: ' . mysql_error());
  5
  6 echo 'Connected successfully';
  7 ?>

连接失败，提示：

Warning: mysql_connect() [function.mysql-connect]: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in /usr/local/Apache2/htdocs/rico.org/test.php on line 2
Could not connect: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

查看发现/var/run下没有mysqld目录，更没有那个.sock文件，不知这个问题如何解决，还请各位高手帮忙，感谢！！！
