Installing Drupal

Hi all,

I'm a newbie in this world, I'd created a DB in PostgreSQL, but not able to reach it.

I'm having this error message when installing DB :
SQLSTATE[HY000] [2006] MySQL server has gone away.

I'm sure of my password & username, also the port (5433).It's hosted locally.

I'm guessing it's coming from Wamp, who doesn't kinda "know" PostgreSQL.

Do you have any idea / tip ?

Thanks a lot.

Package doctrine/reflection is abandoned, you should avoid using it. Use roave/better-reflection instead.

We found this message when we get the composer update.

Drupal 9 requires a higher version of MariaDB ( 10.3.7 ) than earlier versions ( 7/8 ).  Our host only allows one version of the DB per VPS. Will the higher Maria DB version break Drupal 7 or 8 installations?  Thanks.

Steps taken so far:
* Created database MS SQL on a production server
* downloaded Drupal 9.2.7
* Installed php 7.4.24
* Added extensions for pdo, zend, xdebug, opcache etc.
* Ran composer require drupal/sqlsrv:^4.2 to install SQL-driver in my Drupal-folder
* Using Visual Studio Code, I serve the page on my local host and start the installation of Drupal.

Hello,

I am installing drupal 9 with composer and I am getting an all white screen(but strangely, there is drupal icon in header) when I have installed it with composer but before any drupal setup. I have installed Mariadb with DB, Apache, updated PHP, used composer to manually do drupal setup with quick-start script with no change to white screen. I am wondering if anyone has any suggestions. thanks!

I have read that from version 8 it is better to install Drupal with composer.
I have read this article
https://www.morpht.com/blog/drupal-and-composer-part-1-understanding-com...
and if I understand correctly apart from the difficulties of installing drupal with composer on a shared web space (composer installation problems and access from CLI, with plesk or other) it is also critical and should be installed locally and then copied to a production site .
