【中文标题】SQLSTATE[HY000] [2002] 连接被拒绝 Laravel 5.8.35【英文标题】：SQLSTATE[HY000] [2002] Connection refused Laravel 5.8.35 【发布时间】：2020-03-26 21:06:09 【问题描述】：

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] Connection denied (SQL: select * from information_schema.tables where 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

同样的事情

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');

【问题讨论】：

你试过运行php artisan config:clear 是的，都使用 php artisan config:cache 和 php artisan config:clear 在迁移文件中分享您的查询您确定您的数据库已经在运行吗？连接被拒绝意味着您的应用无法连接到数据库 @SalunkeAkash 添加了 【参考方案1】：

试试这个改变
