Problem with poller.php

[Astro]

Whenn I trie to start the poller.php by typing "php poller.php" I get the following Error:

Warning: mysql_pconnect(): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) in /opt/lampp/htdocs/cacti/lib/adodb/drivers/adodb-mysql.inc.php on line 355

my mysqld.sock is in /opt/lampp/run/mysqld.sock

how can I change this?
