MySql ERROR 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: NO)

MySQL

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.

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 – brew install thesql on macOS

I think one can end up in this position with older versions of mysql already installed. I had the same problem and none of the above solutions worked for me. I fixed it thus:

Used brew's remove & cleanup commands, unloaded the launchctl script, then deleted the mysql directory in /usr/local/var, deleted my existing /etc/my.cnf (leave that one up to you, should it apply) and launchctl plist

Updated the string for the plist. Note also your alternate security script directory will be based on which version of MySQL you are installing.

Step-by-step:

brew remove mysql

brew cleanup

launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

sudo rm -rf /usr/local/var/mysql

I then started from scratch:

installed mysql with brew install mysql

ran the commands brew suggested: (see note: below)

unset TMPDIR

mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

Start mysql with mysql.server start command, to be able to log on it

Used the alternate security script:

/usr/local/Cellar/mysql/5.5.10/bin/mysql_secure_installation

Followed the launchctl section from the brew package script output such as,

#start
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

#stop
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

Note: the --force bit on brew cleanup will also cleanup outdated kegs, think it's a new-ish homebrew feature.

Note the second: a commenter says step 2 is not required. I don't want to test it, so YMMV!

Mysql – Enable remote MySQL connection: ERROR 1045 (28000): Access denied for user

You have to put this as root:

GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'IP' IDENTIFIED BY 'PASSWORD' with grant option;

;

where IP is the IP you want to allow access, USERNAME is the user you use to connect, and PASSWORD is the relevant password.

If you want to allow access from any IP just put % instead of your IP

and then you only have to put

FLUSH PRIVILEGES;

Or restart mysql server and that's it.
