接入 Eloquent ORM 时如何配置多个主从数据库？

单读库配置（一主一从）

多写多读配置（多主多从）

针对不同的model或者不同的业务，切换connection，可以吗

创建 DB 类，定义多个数据库方法

<?php
use Illuminate\Database\Capsule\Manager as Capsule;
use Illuminate\Events\Dispatcher;
use Illuminate\Container\Container;

class DB
{
    static public function mysqlMaster()
    {
        $capsule = new Capsule;
        $capsule->addConnection([
            'driver' => 'mysql',
            'host' => '',
            'database' => '',
            'username' => '',
            'password' => '',
            'charset' => '',
            'collation' => 'utf8_unicode_ci',
            'prefix' => '',
        ]);

        $capsule->setEventDispatcher(new Dispatcher(new Container));
        $capsule->setAsGlobal();
        $capsule->bootEloquent();
        return $capsule->getConnection();
    }
}

使用

DB::mysqlMaster()->table('')->where()->get();
