newer version of mysql only allow root login on root user that mean you can only use root user if you run mysql command on root . to fix it just add a password to the account i forget which it is but it look like the method that is mentioned above . after that you can login as root in mysql . i encounter this when i install mysql on ubuntu 18.04 to found out it use the new version that cannot login to root . i spent lot of time reading some stack overflow and finally found the solution
