SQLSTATE [HY000] [2002] Laravel 宅基地内的连接被拒绝

2022-01-23 00:00:00 migration php laravel-5 homestead laravel-artisan

在 Laravel 5.2 中使用 Mac OS X 和 Homestead 2.2.1.

Using Mac OS X and Homestead 2.2.1 with Laravel 5.2.

在终端(在我的项目文件夹中的宅基地内)我可以执行 php artisan 来查看所有可用的命令.当我尝试运行 php artisan migrate 时出现连接错误:
SQLSTATE[HY000] [2002] 连接被拒绝

In terminal (within homestead in my project folder) I can do php artisan to see all the available commands. When I try to run php artisan migrate I get a connection error:
SQLSTATE[HY000] [2002] Connection refused

我已经使用这些 .env 设置设置了一个 Laravel 项目

I have setup a Laravel project with these .env settings 

DB_HOST=127.0.0.1
DB_DATABASE=tcv
DB_USERNAME=homestead
DB_PASSWORD=secret

我还为 DB_HOST 尝试了 localhost，为 DB_USERNAME 和 DB_PASSWORD 尝试了 root.并将这些的所有可能变化放在一起！

I have also tried localhost for DB_HOST and root for DB_USERNAME and DB_PASSWORD. And all possible variations of these put together!

在 Sequel Pro(数据库管理应用程序)中，我可以使用这些设置进行连接

In Sequel Pro (db management application) I CAN connect with these settings

Host       127.0.0.1
Username   homestead
Password   secret
Database   tcv
Port       33060

但是这个数据库显然是空的，因为我不能从终端迁移到它...

But this database is obviously empty, because I cant migrate to it from terminal ...

据我所知，这是一个配置问题，因为我可以使用 Sequel Pro 连接到它.但老实说，我完全不知道设置有什么问题.

As far as I can make out it is a configuration issue, since I can connect to it with Sequel Pro. But I have honestly no freaking idea what is setup wrong.

感谢您的帮助！！

编辑
出于某种原因，在将我的项目移动到 MAMP 并运行 php artisan migrate 时，我得到了相同的 SQLSTATE[HY000] [2002] Connection denied 错误.
现在我完全迷失了......

EDIT
For some reason I get the same SQLSTATE[HY000] [2002] Connection refused error when moving my project to MAMP and running php artisan migrate.
Now I am completely lost ...

问题

在 Laravel 中，您有 config/database.php，所有连接设置都位于其中.您的项目的根目录中还有一个 .env 文件(每个人都使用它来节省时间).这包含可用于整个项目的变量.

In Laravel you have config/database.php where all the setup for the connection is located. You also have a .env file in the root directory in your project (which everyone uses for timesaving). This contains variables that you can use for the entire project.

在标准 L5 项目中，config/database.php 的 MySql 部分如下所示:

On a standard L5 project the MySql section of config/database.php looks like this:

    'mysql' => [
        'driver'    => 'mysql',
        'host'      => env('DB_HOST', 'localhost'),
        'database'  => env('DB_DATABASE', 'forge'),
        'username'  => env('DB_USERNAME', 'forge'),
        'password'  => env('DB_PASSWORD', ''),
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
        'strict'    => false,
        'engine'    => null,
    ],

注意没有设置端口！

虽然在我的 .env 文件中我设置了 DB_PORT=33060.但是那个 value (3306) 从未读入 config/database.php.
所以不要像我一样笨，忘记检查 database.php 文件.

Although in my .env file I had set DB_PORT=33060. But that value (3306) was never read into the config/database.php.
So don't be a dumbass like myself and forget to check the database.php file.

<小时>修复
只需添加 'port' =>env('DB_PORT', 3306), 到您的 config/database.php 并在 .env 中设置该值，如下所示 DB_PORT=3306

FIX
Simply add 'port' => env('DB_PORT', 3306), to your config/database.php and set that value in .env like this DB_PORT=3306
