Question

whenever I am trying to connect phpMyadmin through php script it is showing some errors like this Warning: mysql_connect(): Access denied for user 'www-data'@'localhost' (using password: NO) I am using ubuntu 11.04.So can you tell me how to solve this?

Answer 1

This error simply means that your connection information is incorrect. You are trying to connect to the MySQL database using the username “www-data@localhost” with no password. Check your MySQL permissions to see what you need to do. Either this login needs a password or this login is not specified as being permitted to access the data.

To check what permissions you have for that user, run this MySQL script:

SELECT * FROM user WHERE user='www-data';

To add rights to that user (if they are missing), run this script:

GRANT SELECT ON database.* TO 'www-data'@'localhost';
