PDOException（1045）SQLSTATE [HY000] [1045] Laravel 4.2 MySQL 5.7

Question

感谢您阅读我的问题，我花了一周时间研究这个错误，阅读了 ServerFault、Stackoverflow 和 AskUbuntu 中的问题，但无法找出问题所在。

我有

• Lubuntu 16.04（Ubuntu 发行版）
• Nginx
• Laravel 4.2.17
• MySQL 5.7

我有一个从 GitHub 克隆的预先存在的项目，一切进展顺利，但是当我转到必须连接到数据库的页面（例如尝试登录）时，出现此错误：

PDOException（1045）帮助

SQLSTATE[HY000] [1045] 拒绝用户 'homestead'@'localhost' 访问（使用密码：是）

错误的图形描述

涉及文件

我在项目中有一个 .env 文件，我将其命名为.env.本地.php这是文件：

<?php
/**

* Si se requiere cargar otros valores para un entorno diferente al de produccion (local, development, etc.)
* cree un archivo con el nombre asi:

return [

我有一个数据库.php/var/www/kinbuweb/app/config/local/database.php 中的文件我突出显示了我一直在阅读的 /config/local 路径，如果我有一个本地环境，则该路径是配置（并且我将我的文件命名为 .env。当地的.php) 文件路径为：

我曾尝试过

1. 使用本地的凭证（/var/www/kinbuweb/app/config/local/database.php）数据库.php配置如下：

   <?php
   /**
   * Variables de entorno .env.php
   * Si se requiere cargar otros valores para un entorno diferente al de produccion (local, development, etc.)
   * cree un archivo con el nombre asi:
   *  - local => .env.local.php
   *  - development => .env.development.php
   */
   return [
   
   'DATABASE_NAME' => 'homestead',
   'DATABASE_USER' => 'homestead',
   'DATABASE_PASSWORD' => 'secret',
   
   
   
   'GOOGLE_IDENTIFIER'     => 'GOOGLE_IDENTIFIER',
   'GOOGLE_SECRET'         => 'GOOGLE_SECRET',
   'GOOGLE_CALLBACK_URI'   => 'GOOGLE_CALLBACK_URI',
   
   'FACEBOOK_IDENTIFIER'   => 'FACEBOOK_IDENTIFIER',
   'FACEBOOK_SECRET'       => 'FACEBOOK_SECRET',
   'FACEBOOK_CALLBACK_URI' => 'FACEBOOK_CALLBACK_URI',
   
   
   'PAYU_MACRO_ACCOUNT_ID' => 654321,
   'PAYU_MICRO_ACCOUNT_ID' => 123456,
   'PAYU_MERCHANT_ID' => 123456,
   'PAYU_API_KEY' => 'ABCabc123DEFdef456GHIghi78',
   'PAYU_API_LOGIN' => '123abc456def789',
   'PAYU_TEST' => 1,
   
   ];
   

2. 将端口聚合到本地文件夹中的数据库配置，如下所示：

   <?php
   
   return [
   
   'connections' => [
   
   'mysql' => [
       'driver'   => 'mysql',
       'host'     => 'localhost:3306',
       'database' => 'homestead',
       'username' => 'homestead',
       'password' => 'secret',
       'charset'  => 'utf8',
       'collation' => 'utf8_unicode_ci',
       'prefix'   => '',
       ],
   
   'pgsql' => [
       'driver'  => 'pgsql',
       'host'    => 'localhost',
       'database' => 'homestead',
       'username' => 'homestead',
       'password' => 'secret',
       'charset' => 'utf8',
       'prefix'  => '',
       'schema'  => 'public',
      ],
   
   ],
   
   ];
   

当我遇到同样的错误时： PDOException（1045）帮助

SQLSTATE[HY000] [1045] 拒绝用户 'homestead'@'localhost' 访问（使用密码：是）

有什么办法可以解决这个问题吗？谢谢

Answer 1

尝试在您的 mysql 数据库中为您的用户“homestead”添加权限。

登录mysql并添加权限如下：

mysql -u root -p

输入你的MySQL密码

mysql > grant all privileges on homestead *.* to 'homestead'@'localhost' identified by 'password'; 

这里的“密码”在你的 database.php 中

如果您在本地环境中，database.php 的路径是：

你的项目文件夹/app/config/local

mysql > FLUSH PRIVILEGES;
