Resetting the root MySQL Password on Debian 7.11

The easiest way to reset the root users mysql password on most Debian systems is to use the debian-sys-maint user. The login details for which can be found below:


With the password found in there, you should be able to log in as such.

root@debian7:~# mysql -u debian-sys-maint -p'4St4LWE97I2E'

Now once you’re logged into MySQL, change the root users password like follows:

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('Tkh#4WBI$6%%');
Query OK, 0 rows affected (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

Quit MySQL by typing exit or simply ‘\q‘:

mysql> \q

Then test the login works:

root@debian7:~# mysql -u root -p'Tkh#4WBI$6%%'

Assuming that worked, you might want to create a ~/my.cnf file for easier logins in the future.

root@debian7:~# vim ~/.my.cnf

Replace with your password.

root@debian7:~# cat ~/.my.cnf

Make sure only the intended user can access. Here this is root.

root@debian7:~# chmod -v 600 ~/.my.cnf
mode of `/root/.my.cnf' changed from 0644 (rw-r--r--) to 0600 (rw-------)

Now you should be able to access MySQL as the root user simply with “mysql“:

root@debian7:~# mysql
