Cómo instalar Nginx con PHP y MariaDB (LEMP Stack) en Fedora 31

Con MariaDB 10.4, ahora se te preguntará entre utilizar la contraseña de root o el plugin unix_socket. El plugin unix_socket te permite iniciar sesión en MariaDB con tus credenciales de usuario de Linux. Se considera más seguro, aunque necesitarás un nombre de usuario/contraseña tradicional para utilizar aplicaciones de terceros como PhpMyAdmin. En este tutorial nos limitaremos a utilizar el plugin unix_socket. Puedes seguir utilizando PhpMyAdmin a través de cualquier usuario específico que crees para tus bases de datos.

Al pulsar Intro se elige la opción por defecto (la que está en mayúsculas, Y en este caso).

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): [PRESS 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] [PRESS ENTER]
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] [ANSWER n]

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] [PRESS ENTER]
 ... 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] [PRESS ENTER]
 ... 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] [PRESS ENTER]
 \- 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] [PRESS ENTER]
 ... 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!
