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

Question

I\'m setting up a new server and keep running into this problem.

When I try to login to the MySQL database with the root user, I get the error:

Answer 1

I found my solution after hours of research here.

Stop MySQL

sudo service mysql stop

Make MySQL service directory.

sudo mkdir /var/run/mysqld

Give MySQL user permission to write to the service directory.

sudo chown mysql: /var/run/mysqld

Start MySQL manually, without permission checks or networking.

sudo mysqld_safe --skip-grant-tables --skip-networking &

Log in without a password.

 mysql -uroot mysql

update password

UPDATE mysql.user SET authentication_string=PASSWORD('YOURNEWPASSWORD'), plugin='mysql_native_password' WHERE User='root' AND Host='%';
EXIT;

Turn off MySQL.

sudo mysqladmin -S /var/run/mysqld/mysqld.sock shutdown

Start the MySQL service normally.

sudo service mysql start
