[mysql] MySql ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

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.

This question is related to mysql

The answer is

Is it possible the root password is not what you think it is? Have you checked the file /root/.mysql_secret for the password? That is the default location for the automated root password that is generated from starting from version 5.7.

cat /root/.mysql_secret

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.

just use:

$ sudo mysql

without the "-u root" parameter.

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

You must run your mysql by xampp-controle.exe in folder XAMPP. After that login:

mysql -u root

In my case, I needed to Edit Inbound Rules on my AWS RDS instance to accept All Traffic. The default TCP/IP constraint prevented me from creating a database from my local machine otherwise.

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

mysql -u root -p;

And mysql will ask for the password

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.
