How to get MySql 8 to run with laravel?

Question

I'm having difficulty getting MySQL 8 to work. This is the error that appears everytime I attempt a php artisan migrate. I've reinstalled MySQL only once so far because I didn't want to hurt my head anymore on what was going on. I've edited the database.php from other possible answers, but that also doesn't seem to work. I saw a possible answer that it's because of MySQL 8's sha256 encryption of the root password, which is why I want to go back to MySQL 5.7 which I've looked up works with laravel just fine. Though, I want to keep the packages up to date and keep MySQL 8 only if i can get it to work with laravel.

How do I get MySQL 8 to work with Laravel?

 'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix' => '',
            'prefix_indexes' => true,
            'strict' => true,
            'engine' => null,
            'version' => 8,
            'modes' => [
                'ONLY_FULL_GROUP_BY',
                'STRICT_TRANS_TABLES',
                'NO_ZERO_IN_DATE',
                'NO_ZERO_DATE',
                'ERROR_FOR_DIVISION_BY_ZERO',
                'NO_ENGINE_SUBSTITUTION',
            ],
        ],

UPDATE ANOTHER FIX I DID TO FIX THIS: With a fresh install of MySQL, i selected NO for encrypting passwords in the set up ( using legacy encryption, not the SHA encryption ) and it started to work with Laravel without any problems - Just use a long and strong password. reference of the installation step: https://www.percona.com/blog/wp-content/uploads/2018/05/Installing-MySQL-8.0-on-Ubuntu-2.png

Solution 1

Since PHP doesn't understand caching_sha2_password, set the user back to mysql_native_password:

ALTER USER 'forge'@'localhost'
IDENTIFIED WITH mysql_native_password BY 'new_password'

Solution 2

When running a PHP version before 7.1.16, or PHP 7.2 before 7.2.4, set MySQL 8 Server's default password plugin to mysql_native_password or else you will see errors similar to The server requested authentication method unknown to the client [caching_sha2_password] even when caching_sha2_password is not used.

This worked for me with an addition to the my.ini default_authentication_plugin=mysql_native_password and removing old caching_sha2_password value.

This worked for me when working with a MySQL 8.0+ and doing the Magento 2.3.1 web installation. Don't forget to add the ";" character at the end of the command if you don't want to make additional changes.
