SQLSTATE[HY000] [2002] 连接被拒绝 Laravel 5.8.35

Question

使用 Mac OS X、MAMP 5.5 和 Laravel 5.8.35

当我使用 'php artisan migrate' 时，我收到以下错误消息：

Illuminate\Database\QueryException : SQLSTATE[HY000] [2002] 连接被拒绝 (SQL: select * 来自 information_schema.tables 其中 table_schema = auth and table_name = migrations and table_type = 'BASE TABLE')

在 /Applications/MAMP/htdocs/auth/vendor/laravel/framework/src/Illuminate/Database/Connection.php:664

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

文件.env

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=auth
DB_USERNAME=etn
DB_PASSWORD=pass

与

相同

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=auth
DB_USERNAME=etn
DB_PASSWORD=pass

迁移文件

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUsersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->string('email')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('users');
    }
}

第二个迁移文件：

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreatePasswordResetsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('password_resets', function (Blueprint $table) {
            $table->string('email')->index();
            $table->string('token');
            $table->timestamp('created_at')->nullable();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('password_resets');
    }
}

Answer 1

试试这个改变

  DB_PORT=33060

或

 DB_PORT=8889

更改后停止并重新启动服务器。

Answer 2

其中一个原因是服务器 XAMPP 尚未启动，请尝试检查您在本地主机上是否正确启动它的服务器。
