Расширенная конфигурация кэша объектов.

Используйте эту опцию для определения имен классов и параметров конструкторов, которые используются для различных типов кэша. Пользовательские типы кэша могут быть определены здесь и ссылаться на $wgMainCacheType , $wgMessageCacheType или $wgParserCacheType .

Формат представляет собой ассоциативный массив, где ключ - идентификатор кэша, а значение - ассоциативный массив параметров. Параметр "class" - это имя класса, который будет использоваться. В качестве альтернативы можно указать параметр "factory", который дает вызываемую функцию, генерирующую подходящий объект кэша.

Standard cache types

  • CACHE_ANYTHING - try to find the best available option automatically. Most caches default to this. Will try $wgMainCacheType then MessageCacheType then ParserCacheType (as long as they are set to something usable), then CACHE_DB.
  • CACHE_DB - use the objectcache DB table. Always available but somewhat slow. On a wiki farm, by default it's not shared between multiple wikis, which can cause problems for some use cases.
  • CACHE_MEMCACHED - use Memcached.
  • CACHE_ACCEL - use APCu (or quietly disable caching if it's not available). When writing code, usually you should use MediaWikiServices::getLocalServerObjectCache() instead of using it directly.
  • CACHE_HASH - use in-memory caching, not persisted across requests. Not really useful outside of testing.
  • CACHE_NONE - disable the given type of caching. Usually a bad idea.

Пользовательские типы кэша

Вы также можете создавать другие конфигурации кэша в дополнение к встроенным константам CACHE_, добавляя их. Например, чтобы использовать redis в качестве кэша (который не имеет встроенной константы CACHE_XXX), вы можете сделать следующее: 

$wgObjectCaches['redis'] = [
	'class' => 'RedisBagOStuff',
	'servers' => [
		'127.0.0.1:6379'
	],
	'password' => 'Your-Redis-password', // Highly recommended, otherwise comment out this line.
	'persistent' => true,
];
$wgMainCacheType = 'redis';

На устройстве MediaWiki-Vagrant работает служба redis, и при такой конфигурации.

You can also change the definition of the default cache types. For example, to make the DB cache be shared across wikis: 

$wgObjectCaches[CACHE_DB] = [
	'class' => SqlBagOStuff::class,
	'loggroup' => 'SQLBagOStuff',
	'server' => [
		'type' => $wgDBtype,
		'host' => $wgDBserver,
		'user' => $wgDBuser,
		'password' => $wgDBpassword,
		// or whatever database you use for central data
		'dbname' => 'shared',
	]
];

Значение по умолчанию

The 'slaveOnly' option for SqlBagOStuff (устарело в 1.34), was removed. Use 'replicaOnly' instead.
