Laravel: SQLSTATE[HY000] [2054] The server requested authentication method unknown to the client

Question

after installing a new laravel app 5.7 and trying to migrate I get this error:

Illuminate\Database\QueryException : SQLSTATE[HY000] [2054] The server requested authentication method unknown to the client (SQL: select * from information_schema.tables where table_schema = xxx_db and table_name = migrations)

at C:\xampp\htdocs\xxxxx\vendor\laravel\framework\src\Illuminate\Database\Connection.php:664 660| // If an exception occurs when attempting to run a query, we'll format the error 661| // message to include the bindings with SQL, which will make this exception a 662| // lot more helpful to the developer instead of just the database's errors. 663| catch (Exception $e) {

664| throw new QueryException( 665| $query, $this->prepareBindings($bindings), $e 666| ); 667| } 668|

Exception trace:

This query solved my problem.

 ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root@123';

Worked for me on Ubuntu 18.04.4 :) – Gucu112 Jun 03 '20 at 19:26

better solution than reinstall mysql. **pay attention to the command. The last "root" (... by 'root';) is the password, not the username – alvaropgl Nov 27 '20 at 09:00

worked for me on macOS for Server version: 8.0.21 - Homebrew. just want to mention 'some_password' can be your current working password as well, no need to set new password. – Rohutech Feb 08 '21 at 02:09

Enter to your mysql as root and run this query

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '1234';

You can change 1234 to be your password

Run these commands

php artisan config:clear

php artisan migrate

Note: this worked for me.

Re installed MySQL choosing Legacy Authentication Method as shown in iamge attached SQL Authentication method

Database parameters in .env as follows

DB_CONNECTION=mysql  
DB_HOST=127.0.0.1  
DB_PORT=3306  
DB_DATABASE=database_name  
DB_USERNAME=database_username  
DB_PASSWORD=database_password(if any)

Database parameters in config/database.php

'mysql' => [  
    'driver' => 'mysql',  
    'url' => env('DATABASE_URL'),  
    'host' => env('DB_HOST', '127.0.0.1'),  
    'port' => env('DB_PORT', '3306'),  
    'database' => env('DB_DATABASE', 'database_name'),  
    'username' => env('DB_USERNAME', 'database_username'),  
    'password' => env('DB_PASSWORD', 'database_password'),  
    'unix_socket' => env('DB_SOCKET', ''),  
    'charset' => 'utf8mb4',  
    'collation' => 'utf8mb4_unicode_ci',  
    'prefix' => '',  
    'prefix_indexes' => true,  
    'strict' => true,  
    'engine' => null,

        PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),  
    ]) : [],  
],

Run php artisan migrate from the projects terminal

By Providing DB_SOCKET in .env file this issue can be resolved like this :

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=8889
DB_DATABASE=my_db
DB_USERNAME=root
DB_PASSWORD=
DB_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock

Please Check Server localhost Port on phpmyadmin and .env file like (3306,3307,8889)

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3307
DB_DATABASE=mydb
DB_USERNAME=root
DB_PASSWORD=masterpass

Unfortunetly you changes your mysql user or password. If you user/password changed then go to .env file and change your phpmyadmin user and password. Give your database name

DB_DATABASE=hrms
DB_USERNAME=username
DB_PASSWORD=password

Solution is here with 2 step:

Step 1. You have to edit /etc/mysql/my.cnf file and append this setting in mysqld section:

[mysqld]
default_authentication_plugin= mysql_native_password

Step 2. Then run following mysql command:

CREATE USER 'new_root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123';
GRANT ALL PRIVILEGES ON *.* TO 'new_root'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;

It is better if you restart your mysql service.

   sudo systemctl restart mysql

This problem happens when you have install mysql8 and your code compatible with mysql5
