– Log in to your Linux virtual server via SSH as user root and stop the running MariaDB daemon:
# service mysql stop Shutting down MySQL. SUCCESS!
– Start MariaDB in safe mode with ‘skip-grant-tables’ option. Grant tables store the passwords, so using this option you can login to MariaDB without password:
# mysqld_safe --skip-grant-tables &  14721 131108 19:06:41 mysqld_safe Logging to '/var/lib/mysql/domain.com.err'. 131108 19:06:41 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
Now, you are able to log in to MariaDB without a password:
# mysql -u root Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 1 Server version: 5.5.33a-MariaDB MariaDB Server Copyright (c) 2000, 2013, Oracle, Monty Program Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MariaDB >
Once you are logged in, you can reset your MariaDB root password by executing the following SQL commands:
MariaDB [(none)]> use mysql; MariaDB [(none)]> update user set password=PASSWORD("NEWPASSWORD") where User='root';
Don’t forget to replace ‘NEWPASSWORD’ with your actual password.
Now, flush the privileges and exit from the MariaDB server:
MariaDB > flush privileges; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> exit; Bye
Finally, restart your MariaDB server:
# service mysql restart
Done. You old MariaDB root password is changed and you have a new password.
Now you can log in to MariaDB using the new password:
# mysql -u root -p
