laravel 连接数据库出现错误  

PDOException in Connector.php line 55:SQLSTATE[HY000] [1045] 
Access denied for user 'homestead'@'localhost' (using password: YES)

  

1. 确认./config/database.php 

 env('DB_CONNECTION', 'mysql'),
      'connections' => [

        'sqlite' => [
            'driver' => 'sqlite',
            'database' => env('DB_DATABASE', database_path('database.sqlite')),
            'prefix' => '',
        ],

        'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'studyonline'),
            'username' => env('DB_USERNAME', 'root'),
            'password' => env('DB_PASSWORD', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8',
            'collation' => 'utf8_general_ci',
            'prefix' => '',
            'strict' => true,
            'engine' => null,
        ],
        // ...
     ]
]

  

2. 检查.env文件

  默认的配置导致的错误

DB_DATABASE=homestead

DB_USERNAME=homestead

DB_PASSWORD=secret

APP_NAME=Laravel
APP_ENV=local
APP_KEY=base64:cdQLOKNt6JfRuIwfABQ/rqDuR42lgFi8qCC5b4R/KsI=
APP_DEBUG=true
APP_URL=http://localhost

LOG_CHANNEL=stack

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=studyonline
DB_USERNAME=root
DB_PASSWORD=

  

3. 重启服务

php artisan cache:clear
php artisan config:clear
php artisan serve

  

cd ./public
php -S localhost:9000

  

laravel artisan 一些命令

* 创建model

php artisan make:model Video

 执行后生成 ./app/Video.php

  

* 创建Controller

php artisan make:controller UserController

 执行后生成  ./app/Http/Controllers/UserController.php

 

* 创建数据库消息队列的数据表迁移文件

php artisan queue:table

  => database/migrations/2018_07_21_033228_create_jobs_table.php

php

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

class CreateJobsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('jobs', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('queue')->index();
            $table->longText('payload');
            $table->unsignedTinyInteger('attempts');
            $table->unsignedInteger('reserved_at')->nullable();
            $table->unsignedInteger('available_at');
            $table->unsignedInteger('created_at');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('jobs');
    }
}
迁移文件
php artisan migrate

jobs.sql

 假设数据库名为 laravel, 导出这个表

mysqldump -uroot -hlocalhost -p --databases laravel --tables jobs > jobs.sql

  创建controller

php artisan make:controller WelcomeController

Timestamps

By default, Eloquent expects created_at and updated_at columns to exist on your tables. If you do not wish to have these columns automatically managed by Eloquent, set the $timestamps property on your model to false:
