I've tried multiple solutions from StackOverflow but haven't had any success. I'm on Mac OSX (Sierra 10.12.3) trying to create a new database and user. From terminal I enter:
mysql -u root
which outputs this error:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
To try and resolve it I stopped mysql from 'System Preferences', then from terminal typed:
sudo mysqld_safe —skip-grant-tables
I opened a second tab and entered:
mysql -u root
Then from in mysql:
update mysql.user set password_expired = 'N', authentication_string=PASSWORD('newpassword') where user = 'root';
flush privileges;
I then restart the computer (killing the process with CMD + C doesn't work). After restarting, trying mysql -u root still produces the same error.
I am able to access mysql via a MySQL client and a non-root user.
Any help is appreciated.
Just to confirm: You are sure you are running MySQL 5.7, and not MySQL 5.6 or earlier version. And the plugin column contains "mysql_native_password". (Before MySQL 5.7, the password hash was stored in a column named password. Starting in MySQL 5.7, the password column is removed, and the password has is stored in the authentication_string column.) And you've also verified the contents of authentication string matches the return from PASSWORD('mysecret'). Also, is there a reason we are using DML against the mysql.user table instead of using the SET PASSWORD FOR syntax? – spencer7593
So Basically Just make sure that the Plugin Column contains "mysql_native_password".
Not my work but I read comments and noticed that this was stated as the answer but was not posted as a possible answer yet.
