Question

我有两个在不同端口（3333和3306）上运行MySQL的实例

来自工作台的图片

我的laravel项目正在处理3333端口的那个使用这些代码

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3333
DB_DATABASE=bglee
DB_USERNAME=root
DB_PASSWORD=

我现在想让它处理端口3306

我将上述代码编辑为

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

但现在他仍然使用第一个端口（3333）

如果运行php artisan migrate，它会在第一个实例（3333）中创建表

不幸的是，我希望Laravel能够处理第二个问题（3306）

因为它已更新MySQL版本

在Laravel文档中有关于此的一些信息，如5.6版所示： https://laravel.com/docs/5.6/database#using-multiple-database-connections

因此，在config/database.php文件中，您将创建另一个镜像原始连接的连接，但使用正确的端口，可能是这样的：

...
'connections' => [
    ...
        'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'strict' => true,
            'engine' => null,
        ],

        'mysql_2' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST_2', '127.0.0.1'),
            'port' => env('DB_PORT_2', '3306'),
            'database' => env('DB_DATABASE_2', 'forge'),
            'username' => env('DB_USERNAME_2', 'forge'),
            'password' => env('DB_PASSWORD_2', ''),
            'unix_socket' => env('DB_SOCKET_2', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'strict' => true,
            'engine' => null,
        ],
    ...
],

然后，在.env文件中，您可以输入以下值：

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

DB_CONNECTION_2=mysql_2
DB_HOST_2=127.0.0.1
DB_PORT_2=3333
DB_DATABASE_2=bglee
DB_USERNAME_2=root
DB_PASSWORD_2=

最后，您可以使用php artisan migrate --database=mysql_2迁移到特定数据库。

不确定这是否是适合您情况的最佳方式，但这就是我尝试和接近它的方式。

将laravel连接到另一个MySQL
