Debian12.14 : MariaDB , WordPress Install

1. MariaDB

1.1 Install

# apt -y install mariadb-server

MariaDB version confirmation

# mariadb -V
mariadb  Ver 15.1 Distrib 10.11.14-MariaDB, for debian-linux-gnu (x86_64) using  EditLine wrapper

1.2 MariaDB Server Security Settings

MariaDB comes with a default security script, mariadb-secure-installation, which can be used to improve the security of your MariaDB installation, including

Set a password for the root account (if necessary).
Disable remote root login to the database.
Delete anonymous user accounts.
Delete the test database to which anonymous users have access by default.

# systemctl restart mariadb
# mariadb-secure-installation

Installation Status

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): [Enter]
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]y
Enabled successfully!
Reloading privilege tables..
 … Success!

You already have your root account protected, so you can safely answer 'n'.

Change the root password? [Y/n] y
New password: [Any Password]
Re-enter new password: [Any Password again]
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!
