Reset MySQL Root User Password


Go to start of metadata
If you don't remember the Mysql root user's password, you can use this tip:
root@server:~# mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
1) Debian has an user for manteinance jobs on mysql, and the credentials are saved on a file:
root@server:~# cat /etc/mysql/debian.cnf
# Automatically generated for Debian scripts. DO NOT TOUCH!
[client]
host = localhost
user = debian-sys-maint
password = xxxxxxxxxxxxxxxx
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host = localhost
user = debian-sys-maint
password = p2DsK1FdSRgfrafjT
socket = /var/run/mysqld/mysqld.sock
basedir = /usr
root@server:~#
2) Now access mysql with debian's user&pass and change the password for root user:
root@server#>mysql -u debian-sys-maint -p
mysql> use mysql;
mysql> UPDATE user SET password=PASSWORD('new_pass') WHERE user='root';
Query OK, 1 rows affected (0.07 sec)
Rows matched: 1 Changed: 1 Warnings: 0
 
3) Then exit and reload Mysql
mysql> exit
root@server:~# service mysql reload
root@server:~# mysql -u root -pnew_pass
