Laravel/Laravel-admin 使用多个数据库连接

1、配置.env 文件

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



DB_HOST_CENTER=127.0.0.1
DB_PORT_CENTER=3306
DB_DATABASE_CENTER=yhadmin_sub
DB_USERNAME_CENTER=root
DB_PASSWORD_CENTER=root
DB_PREFIX=yh_

2、配置 config/database.php

   '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_center' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST_CENTER', 'localhost'),
            'port' => env('DB_PORT_CENTER', '3306'),
            'database' => env('DB_DATABASE_CENTER', 'forge'),
            'username' => env('DB_USERNAME_CENTER', 'forge'),
            'password' => env('DB_PASSWORD_CENTER', ''),
            'charset' => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix' => env('DB_PREFIX', ''), //数据库前缀
            'strict' => false,
            'engine' => null,
        ],

3、创建 model

a、这个model将采用默认的'mysql'连接
class UserModel extends Model
{
        // 数据库'database'中的users表
        protected $table = "users";
}

b、 这个model将使用mysql_center连接
class UserModel extends Model
{
    // 数据库'dadtabase_center'中的users表
        protected $connection = 'mysql_center';
        protected $table = "users";

}
