How to change root password to an empty one?
How can I change the root password to an empty one in MySql?
The following gives "Access denied for user 'root'@'localhost' (using password: YES)" error. I'm sure I've typed my password correct (it's only 123456)
mysqladmin -u root -p'123456' password ''
I've run this sql successfully but I can still access with my password 123456 and not with an empty one:
use mysql; update user set password=PASSWORD("") where User='root';
Answer
You should restart the MySQL server or run the following command:
FLUSH PRIVILEGES;
MySQL doesn't immediately "see" the changes you make to the tables containing user account data, hence the need for this additional step.
