In my linux server , there is phpmyadmin installed , I can use root user to login phpmyadmin via web browser , after I changed the mysql root password ( use command line ) , I no longer use the root user to login phpmyadmin .
I just tried to reset the mysql root password in command line , but still can not use the new password to lgoin phpmyadmin , the error is #2002 Cannot log in to the MySQL server , would advise how to fix it ? is it possible to change the phpmyadmin to null password ? thanks

I advise against using phpmyadmin. It is a common attack vector for hacking servers. You would better be served by learning MySQL and creating yourself scripts for common tasks (e.g. backing up the database, etc). I realize most people who use phpmyadmin don't like to hear that but I implore you to avoid using it.

Update the root password using following query after reaching on mysql prompt

Quote:

UPDATE mysql.user SET Password=PASSWORD('new-password-here') WHERE User='root' AND Host='host-name-here';

Do you know the correct hostname of user root?

Are you able to log into mysql root account through command line? Suppose your host is 127.0.0.1, your username is root.

Quote:

# mysql -h 127.0.0.1 -u root -p

It will ask for password. Put your password here. It should open mysql prompt.

Are you not able to open mysql prompt as a user root?

Did you restart mysql after updating root password?

Yes, it should be.
If you can log into mysql prompt, can you paste output of this query?

Code:

SELECT * FROM mysql.user WHERE User='root';

You can not login using blank password in phpmyadmin but you can log into mysql command prompt using blank password.
If you want to log into phpmyadmin without password, you have to give hard coded username password in config.inc.php file of phpmyadmin.

If you have used older versions of xampp where XAMPP security concept was not implemented, you can log into phpmyadmin without login screen as a root user. Just open the link http://localhost/phpmyadmin and you are inside the phpmyadmin.

If you put these values in config.inc.php of phpmyadmin where root password is blank in user table of mysql database, it does not promt for username and password and you can loginto phpmyadmin without login credentials.

Code:

$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
$cfg['Servers'][$i]['extension'] = 'mysql';
$cfg['Servers'][$i]['AllowNoPassword'] = true;

By the way, How many accounts of LQ do you have, it is not the same account from where you asked the question.
