Laravel [1045] 解决方法 Access denied for user 'homestead'@'localhost'

## 1.确认database.php文件配置正确。

首先检查database.php中自己填写的信息是正确的。

## 2.检查.env文件

这是默认的.env文件

APP_ENV=local
APP_KEY=
APP_DEBUG=true
APP_LOG_LEVEL=debug
APP_URL=http://localhost

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

BROADCAST_DRIVER=log
CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

PUSHER_APP_ID=
PUSHER_KEY=
PUSHER_SECRET=

取对应的数据库部分
我用的是mysql数据库

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

## 3.修改.env文件

将上述的部分做如下修改

DB_CONNECTION=mysql
DB_HOST=[你的数据库地址]
DB_PORT=[端口（3306）]
DB_DATABASE=[数据库]
DB_USERNAME=[用户名]
DB_PASSWORD=[密码]

## 4.重启服务

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

cd app/Providers

vim AppServiceProvider.php:

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Schema;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        Schema::defaultStringLength(191);
    }

    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}
