This article demonstrates how to Config Redis for Magento 2: page and session. It contains the following section:
Magento’s caching is implemented by Magento\Framework\App\CacheInterface
Add a configuration similar to the following to app/etc/env.php
'cache' =>
array(
'frontend' =>
array(
// Default Cache
'default' =>
array(
'backend' => 'Cm_Cache_Backend_Redis',
'backend_options' =>
array(
'server' => '127.0.0.1',
'database' => '0',
'port' => '6379'
),
),
// Full page cache
'page_cache' =>
array(
'backend' => 'Cm_Cache_Backend_Redis',
'backend_options' =>
array(
'server' => '127.0.0.1',
'port' => '6379',
'database' => '1',
'compress_data' => '0'
)
)
)
),
default, page_cache: Specify the segment name to use a particular segment or a default shortcut for all other caches.
The default cache segment enables you to configure all cache segments except for page_cache (the full page cache).
server: Absolute URL to your Redis server, or 127.0.0.1 if Redis is installed on the Magento server, or an absolute path to a UNIX socket.port: Redis server listen portdatabase: Required if you use Redis for both the default and full-page cache. You must specify the database number of one of the caches; the other cache uses 0 by default.
Important: If you use Redis for more than one type of caching (for example, default cache and page cache), the database numbers must be different.
password: Specifies a password if your Redis server requires authentication.compress_data: Required only for the full page cache. Set to 1 to compress the full page cache. Redis chooses a compression algorithm in the following order, based on availability: snappy, l4z, or lzf. If none of them available, Redis uses gzip.To verify that Redis and Magento are working together, use the following commands:
Redis ping command: redis-cli ping
You will receive PONG in the console
Redis monitor command: redis-cli monitor
Refresh your storefront page and you’ll see output similar to the following.
If you use Redis for page caching, you’ll see output similar to the following:
