mysql problem !!!
 

[3]+ Stopped vim db_conf.php
[root@www config]# mysql
ERROR 1045: Access denied for user: 'root@localhost' (Using password: NO)
[root@www config]# mysql -u root
ERROR 1045: Access denied for user: 'root@localhost' (Using password: NO)
[root@www config]# mysql -u root -p
Enter password:
ERROR 1045: Access denied for user: 'root@localhost' (Using password: YES)
[root@www config]#

what happen ?
Why I can't login to mysql prompt ?

Thanks in advance.

Did you change your hostname after setting up mysql? Did you ever setup root to have a login from localhost? Did you remove that access from localhost? Did you setup any other users with access to login and hopefully have full access?
