Cache Back

Configuration

• The cache configuration file is located at ./config/cache.php.
• Laravel supports popular caching backends like Memcached and Redis out of the box.
• By default, Laravel is configured to use the file cache driver, which stores the serialized, cached objects in the filesystem.
• For larger applications, it is recommended that you use an in-memory cache such as Memcached or APC.

Cache Prerequisites(先決條件)

Database

• When using the database cache driver, you'll need to setup a table to contain the cache items.

Schema::create('cache', function($table){
    $table->string('key')->unique();
    $table->text('value');
    $talbe->integer('expiration');
});

Memcached

• Using the Memcached cache requires the Memcached PECL package to be installed.
• The default configuration uses TCP/IP based on Memcached::addServer.

'memcached' => [
    [
        'host' => '127.0.0.1',
        'port' => 11211,
        'weight' => 100
    ],
],

• You may also set the host option to a UNIX socket path. If you do this, the port option should be set to 0.

`memcached` => [
    [
        'host' => '/var/run/memcached/memcached.sock',
        'port' => 0,
        'weight' => 100
    ],
],

Redis

• Before using a Redis cache with Laravel, you will need to install the predis/predis package (~1.0) via Composer.
