Wondering how to reset the MariaDB root password on EC2? We can help you.
By default, MariaDB 5.5 on Amazon Linux 2 doesn’t have a root password.
While we create a root password for MariaDB and then lock yourself out of the database, we must reset the root password.
Here, at Bobcares, we assist our customers with several AWS queries as part of our AWS Support Services.
Today, let us see how we can reset the root password.
Reset the MariaDB root password on EC2
We need to make note that, while we reset the root password, we will not be able to query the database.
Moving ahead, let us see how our Support Techs go about the password reset.
- First and foremost, we need to verify that we have a recent snapshot of the volume on which the MariaDB data directory resides. If necessary, we can recreate the volume from this snapshot.
- Then we go ahead and stop the MariaDB service:
sudo systemctl stop mariadb
Copy Code - After that, we start MariaDB in safe mode:
sudo mysqld_safe --skip-grant-tables --skip-networking &
Copy Code - We then log in to the MariaDB monitor:
mysql -u root
Copy Code - Here, we update the MariaDB root password:
UPDATE mysql.user SET Password = PASSWORD('new_password_here') WHERE User = 'root'; The output looks like this: Query OK, 1 row affected (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 0
Copy Code - Then we flush the privileges to reload the grant tables. Once, it reloads, the new password takes effect.
FLUSH PRIVILEGES;
Copy Code - Now we exit the MariaDB monitor:
exit
Copy Code - Eventually, we stop the MariaDB process:
sudo kill `sudo cat /var/run/mariadb/mariadb.pid`
Copy Code - Then we start the MariaDB service:
sudo systemctl start mariadb
Copy Code - Finally, we test the new MariaDB root password:
mysql -u root -p
Copy Code
