mysql can't login as root, reinstall doesnt work

Question

I just installed mysql, but i think I did something wrong when changing root password. After the password change, I can't login as root anymore.

The error is :

mysql -uroot
ERROR 1524 (HY000): Plugin '*81F5E21E35407D884A6CD4A731AEBFB6AF209E1B' is not loaded

I have tried to reinstall and delete everything, but after reinstall, still can't login. It seems that the user data remain intact. Any idea how?

Additional note : If we login with command "mysql", although we have the mysql prompt, we can't do anything, we dont have right for anything.

Thank a lot

Answer 1

how about you download latest version of MySQL and try reinstall after remove everything. That should solve you problem as the error stated about missing plugin.
