MySql ERROR 1045 (28000): Access denied for user &

Question

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.

Answer 1

mysql -u root -p;

And mysql will ask for the password

Answer 2

Comment by @Niagaradad helped me. I was entering the wrong password the whole time.

Notice the error message

ERROR 1045 (28000): Access denied for user 'ayaz'@'localhost' (using password: YES)

It says, Password: Yes. That means I am sending the password to SQL and that is wrong.

Usually root account doesn't have password if you haven't set one. If you have installed mysql via homebrew then root account won't have a password.

Here is the comment.

so, not exactly the same then. NO means you are not sending a password to MySQL. YES means you are sending a password to MySQL but the incorrect one. Did you specifically set a password for the mysql root user when you installed MySQL? By default there is no password so you can use mysql -u root -p and hit enter.

Answer 3

If you need to skip the password prompt for some reason, you can input the password in the command (Dangerous)

mysql -u root --password=secret

Answer 4

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.

Answer 5

Try this (on Windows, i don't know how in others), if you have changed password a now don't work.

1) kill mysql 2) back up /mysql/data folder 3) go to folder /mysql/backup 4) copy files from /mysql/backup/mysql folder to /mysql/data/mysql (rewrite) 5) run mysql

In my XAMPP on Win7 it works.

Answer 6

For security reason mysql -u root wont work untill you pass -p in command so try with below way

 mysql -u root -p[Enter]
 //enter your localhost password
