The server requested authentication method unknown to the client [caching_sha2_password]

[al77ex1]

1. I created the entity.

<?php
//
// src/Entity/Post.php
namespace App\Entity;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass="App\Repository\PostRepository")
 */
class Post
{
    /**
     * @ORM\Id
     * @ORM\GeneratedValue
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(type="string", length=128)
     */
    protected $name;

    /**
     * @ORM\Column(type="string", length=128)
     */
    protected $last_name; 
    
    /**
     * @ORM\Column(type="string", length=32)
     */
    protected $phone; 
    
    /**
     * @ORM\Column(type="string", length=32)
     */
    protected $profession; 
    
    /**
     * @ORM\Column(type="decimal", nullable=true)
     */
    protected $age; 
    
    /**
     * @ORM\Column(type="decimal", nullable=true)
     */
    protected $salary; 

    /**
     * @ORM\Column(type="text", nullable=true)
     */
    protected $notice;

    /**
     * @ORM\Column(type="datetime", nullable=true)
     */
    protected $created;

    /**
     * @ORM\Column(type="datetime", nullable=true)
     */
    protected $updated;
}

2. I execute the command: bin/console doc:sch:crea and after that, the console:

 !                                                                                                                      
 ! [CAUTION] This operation should not be executed in a production environment!                                         
 !

Hi @al77ex1 ,

There seems to be a problem with MySql 8.0 forcing new password formats... More info here

Try changing mysql version in docker-compose.yml

from

mysql:8.0

to

mysql:5.6

That should make it work, as MySql 5.6 is a stable version.

Cheers,
Joey

Try changing mysql version in docker-compose.yml
from
mysql:8.0
to
mysql:5.6

now in the console:

 !                                                                                                                      
 ! [CAUTION] This operation should not be executed in a production environment!

Hi again @al77ex1 ,

It seems as if it can't connect to the database. Have you updated the .env file with the parameters from the mysql image?

Here's a guide on how to do this (check step 6)

[al77ex1]

It works now!

Thank you very much!

[carlosguijarro]

Where is docker-compose.yml located?

[joeymasip]

It's in the project root.

Bonjour à tous,

je me permet de poster ce commentaire pour donner la solution que j'ai trouvé à cette même erreur que j'ai rencontré aujourd'hui.

Il s'avère que mon problème se trouvait au niveau du fichier .env à la ligne suivante :

DATABASE_URL="mysql://db_user:password@127.0.0.1:3306/dbname?serverVersion=5.7"

Afin de créer une base de donnée en symfony, il est primordial d'adapter cette ligne à votre configuration. Vous devez remplacer db_user par root, password par root pour ceux pour lesquels le mot de passe est root (pour ma part par exemple) ou sinon ne rien mettre, pour certain serveur local il n'a pas de mot de passe. Ensuite à la place de dbname, vous devez mettre le nom que vous voulez donner à votre futur base. MAIS CE N'EST PAS FINI !! Si vous vous contentez seulement de ces modifications, vous rencontrerez la même erreur ou pas ! Pour ma part, j'ai rencontré cette erreur, car je devais aussi changer le numéro de port, qui est initialement 3306, sauf pour ceux qui utilise MAMP (sur mac), le port qu'utilise MAMP pour mysql est 8889. Donc en remplaçant 3306 par 8889 cela fonctionne :).
