Cannot connect_Access Denied

Hi Iam very new to this and don't know very much about mysql but would like to learn but I cannot seem to get everything working right. Ihave set up apache which is working and php which is working and also msql but whenever I try to access mysql i get
Warning: mysql_connect() [function.mysql-connect]: Access denied for user: 'xxxx@127.0.0.1' (Using password: YES) in c:\public_html\test.php on line 3
I set the username and password in the Mysql admin do I need to set the password elsewhere? Not sure if I have layed out enough info if not I can explain more. Thanks for any help

try using the following code to connect to your database

$dbConn = mysql_connect("localhost","root");

I couldnt connect to mysql server with the above code
Web server returned the following error:


But the code $dbConn = mysql_connect("172.16.4.1","root") is OK (the connect is suscessfull)
Could you tell me why ?

Ive Installed RedHat Linux7, Apache, PHP4.01, mySQL (rpm files included in RedHat Linux7 CDs) on the same server.

search for localhost or 127.0.0.1 in ur config file

it seems that you ' ve set your server to work online (with a constant IP)
pointing ur browser to URL(your IP)/phpinfo.php might help u get more info about ur settings
