The following instructions works for MySQL 5.7. You will need to stop the MySQL server and start it with
mysqld_safe with the option
sudo service mysql stop sudo mysqld_safe --skip-grant-tables & mysql -u root mysql
If you get an error on start, chances are there is no folder created for the
mysqld_safe executable to run, on my tests I was able to solve by doing:
sudo mkdir /var/run/mysqld sudo chown -R mysql:mysql /var/run/mysqld
And then trying to start the
mysqld_safe process again.
After this, the MySQL console will pop up, and you need to set up a new password for
root. The second line is necessary due to a MySQL bug #79027:
UPDATE mysql.user SET authentication_string=PASSWORD('mypassword') WHERE User='root'; UPDATE mysql.user SET plugin="mysql_native_password" WHERE User='root'; FLUSH PRIVILEGES;
Once finished, kill all MySQL processes and start the service again:
ps aux | grep mysql sudo kill -9 [pid] sudo service mysql start
Done, you have reset the
root password! Make sure to keep it safe this time around!
