Step 5: Securing MariaDB on Ubuntu 20.04

As there are by default settings so for security reasons we’ve to update the settings so that we are not open to vulnerabilities. To do this secure the MariaDB installation on Ubuntu 20.04 with the help of below command.

sudo mysql_secure_installation

You’ll see the similar output.

sabi@Ubuntu-20:~$ sudo mysql_secure_installation
 [sudo] password for sabi: 
 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
 haven't set the root password yet, you should just press enter here.
 Enter current password for root (enter for none): 
 OK, successfully used password, moving on…
 Setting the root password or using the unix_socket ensures that nobody
 can log into the MariaDB root user without the proper authorisation.
 You already have your root account protected, so you can safely answer 'n'.
 Switch to unix_socket authentication [Y/n] N
  … skipping.
 You already have your root account protected, so you can safely answer 'n'.
 Change the root password? [Y/n] Y
 New password: 
 Re-enter new password: 
 Password updated successfully!
 Reloading privilege tables..
  … Success!
 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
 production environment.
 Remove anonymous users? [Y/n] y
  … Success!
 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] y
  … Success!
 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] y
 Dropping test database…
 … Success!
 Removing privileges on test database…
 … Success! 
 Reloading the privilege tables will ensure that all changes made so far
 will take effect immediately.
 Reload privilege tables now? [Y/n] y
  … Success!
 Cleaning up…
 All done!  If you've completed all of the above steps, your MariaDB
 installation should now be secure.
 Thanks for using MariaDB!

Make sure to check the MariaDB Server status as it will start automatically after completing the installation. Run the below command to see the status of MariaDB on Ubuntu 20.04.

systemctl status mysql

After it test the login by providing the above details configured in the above step.

sabi@Ubuntu-20:~$ mysql -u root -p
 Enter password:
