Laravel/Laravel-admin 使用多个数据库连接

Posted 2021-03-17 搬砖小伙子

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";

}
