laravel实现数据库多库配置,读写分离配置或者多读写分离配置

	'connections' => array(
         //默认mysql配置,访问test库
		'mysql' => array(
			'driver'    => 'mysql',
			'host'      => '192.168.16.70',
			'port'		=>  '3306',
			'database'  => 'test',
			'username'  => 'test',
			'password'  => '123456',
			'charset'   => 'utf8',
			'collation' => 'utf8_unicode_ci',
			'prefix'    => '',
		),
        //自定义mysql连接,访问media库
		'media' => array(
			'read' => array(
		        array('host' => '192.168.16.74','port' => 3306),
		        array('host' => '192.168.16.70','port' => 3306),
	   		),
		    'write' => array(
		        'host' => '192.168.16.70', 'port'=> 3306
		    ),
			'driver'    => 'mysql',
			'database'  => 'media',
			'username'  => 'test',
			'password'  => '123456',
			'charset'   => 'utf8',
			'collation' => 'utf8_unicode_ci',
			'prefix'    => '',
		),
     )

　　

这样使用,新建一模型User.php

class User extends Eloquent{
 //不设置属性，默认连接mysql配置
	protected $connection = 'media';
}
