Magento使用Memcached 缓存数据方法

修改 

app/etc/env.php

添加以下代码

 'cache' => [
        'frontend' => [
            'default' => [
                'backend' => 'Magento\Framework\Cache\Backend\Memcached',
                'backend_options' => [
                    'servers' => [
                        [
                            'host' => '127.0.0.1',
                            'port' => '11211'
                        ]
                    ],
                    'compression' => false
                ]
            ],
            'page_cache' => [
                'backend' => 'Magento\Framework\Cache\Backend\Memcached',
                'backend_options' => [
                    'servers' => [
                        [
                            'host' => '127.0.0.1',
                            'port' => '11211'
                        ]
                    ],
                    'compression' => false
                ]
            ]
        ]
    ],

默认放sesession到DB中

   'session' => [
        'save' => 'db'
    ],

可以修改把session放到memcached中

'session' =>
    array (
      'save' => 'memcached',
      'save_path' => 127.0.0.1:11211'
),
