phpmyadmin,cant access

i have moved mysql data files to another dir.
and changed mysql config files.
so now mysql database can be access and used.

but when using phpmyadmin,it says wrong username/password.
what else can i do?

i think the reason may be i moved mysql data files.
how can i set the phpmyadmin working?

thank you.

 

thank you.
i just reset the root password in WHM
it says:
DBI connect('mysql:localhost','root',...) failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) at /scripts/restartsrv_mysql line 74
mysql has failed, please contact the sysadmin (result was "mysql has failed").


what can i do?
thank you.

 

yeah.i fixed it.
just place a shortcut to the mysql.sock
