Login ERROR 1698 (28000): Access denied for user 'root'@'localhost'

Question

I just installed MySQL server on my Ubuntu machine. All installed ok, when it asked for my password, I simply hit 'enter' so as to leave the password blank. Now when I try to login:

mysql -u root -p

and simply hit enter, I get the following error:

ERROR 1698 (28000): Access denied for user 'root'@'localhost'

I don't understand what the error is or how to fix it. Please can someone help? I've tried to read the MYSQL Docs but I don't understand what they're saying.

I also get an "Access Denied" page when I try to access phpMyAdmin

Answer 1

Had the same issue. Executing with Super user privileges worked for me.

sudo mysql -u root -p

Answer 2

您是否尝试省略-p进行免费密码登录？

mysql -u root
