SQLSTATE[HY000] [1698] Access denied for user 'root'@'localhost'

Question

I just installed Ubuntu 16.04 and installed web server on it. Everything works well, but I cannot access database. Even if I create new user and grant all privileges, I can\

Answer 1

To create user for phpMyAdmin :

sudo mysql -p -u root

Now you can add a new MySQL user with the username of your choice.

CREATE USER 'USERNAME'@'%' IDENTIFIED BY 'PASSWORD';

And finally grant superuser privileges to the user you just created.

GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'%' WITH GRANT OPTION;
