Error in Mysql

Hi to all ! I have the following mistake when I attempt to connect to mysql. I do the following: $host = "localhost"; $user = "php"; $pass = "php"; $con = mysql_connect($host, $user, $pass); when I try to wacth the results on netscape I get the follwing message: Mysql Connection Failed. Cannot connect to local Mysql server trough socket /var/lib/mysql/mysql.sock As I recently installed mysql I thought that it could be a problem of not having the php user enabled, so I created a user php with password php and host localhost in the user table, is that ok? If not, how can I do to create a user to access certain databases?? Thanks a lot, Nicolas
