secure enough. Would you like to setup VALIDATE PASSWORD component?

By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL 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? (Press y|Y for Yes, any other key for No) : 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? (Press y|Y for Yes, any other key for No) : Y
Success.
By default, MySQL 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? (Press y|Y for Yes, any other key for No) : 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? (Press y|Y for Yes, any other key for No) : Y
Success.
All done!
Login as root and create a dedicated admin account that is secured by a password.
$ sudo mysql
From within the shell, create a dedicated user with root privileges that is secured by a strong password. Replace admin and strong_password with the desired username and password.
mysql> CREATE USER 'admin'@'localhost' IDENTIFIED BY 'strong_password';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;
mysql> EXIT
Enable Mysql to automatically start with the system.
$ sudo systemctl enable mysql
$ sudo systemctl start mysql
$ sudo systemctl stop mysql
