I’m wanting to do some development on my laptop so as MariaDB has replaced mySQL I’ve installed that. It was simple enough all you need to do is run dnf install mariadb done.
However when I ran my usual mysql -uroot -p the password for root on my laptop didn’t work. So what was the root password.
Well in my case it was the default and on Fedora 24 that’s a blank password.
[root@sheldon paulmellors]# mysql -u root -p
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 3

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the current input statement.
ok so now i’m in, but I don’t want a blank root password what do I do.
Well you can just set the root password using a funky sql command, however there is a tool that comes with MariaDB that does it all for you.
[root@sheldon paulmellors]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we’ll need the current
password for the root user. If you’ve just installed MariaDB, and
you haven’t set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on…
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] y
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
Remove anonymous users? [Y/n]
Normally, root should only be allowed to connect from ‘localhost’. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n]
By default, MariaDB comes with a database named ‘test’ that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n]
– Dropping test database…
– Removing privileges on test database…
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n]
All done! If you’ve completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
There you go, simple when you know how.
