Redis sessions, cache & queues

This library allows using Redis as cache, session and for the queue. You can only enable these services by using a local extender (the extend.php in the root of your Flarum installation). See the "Set up" section below.

This is an advanced utility for webmasters!

Installation

Install manually with composer:

composer require blomstra/flarum-redis:*

Set up

In your extend.php:

return [
    new Blomstra\Redis\Extend\Redis([
        'host' => '127.0.0.1',
        'password' => null,
        'port' => 6379,
        'database' => 1
    ])
];

This enables sessions, cache and queue to run on redis.

See "Use different database for each service" below to split up the database for cache vs sessions, queue because a cache clear action will clear sessions and queue jobs as well if they share the same database.

Advanced configuration

1. Disable specific services:

return [
    (new Blomstra\Redis\Extend\Redis([
        'host' => '127.0.0.1',
        'password' => null,
        'port' => 6379,
        'database' => 1,
    ]))->disable(['cache', 'queue'])
];

2. Use different database for each service:

return [
    (new Blomstra\Redis\Extend\Redis([
        'host' => '127.0.0.1',
        'password' => null,
        'port' => 6379
    ]))
    ->useDatabaseWith('cache', 1)
    ->useDatabaseWith('queue', 2)
    ->useDatabaseWith('session', 3)
];

3. Completely separate the config array:

return [
    (new Blomstra\Redis\Extend\Redis([
        'connections' => [
            'cache' => [
              'host' => 'cache.int.yoursite.com',
              'password' => 'foo-bar',
              'port' => 6379,
              'database' => 1,
            ],
            'queue' => [
              'host' => 'queue.int.yoursite.com',
              'password' => 'foo-bar',
              'port' => 6379,
              'database' => 1,
            ],
            'session' => [
              'host' => 'session.int.yoursite.com',
              'password' => 'foo-bar',
              'port' => 6379,
              'database' => 1,
            ],
        ],
    ]))
];

4. Use a cluster:

return [
    (new Blomstra\Redis\Extend\Redis([
        'host' => '127.0.0.1',
        'password' => null,
        'port' => 6379,
        'options' => [
          'replication' => 'sentinel',
          'service' => 'mymaster:26379',
        ]
    ]))
    ->useDatabaseWith('cache', 1)
    ->useDatabaseWith('queue', 2)
    ->useDatabaseWith('session', 3)
];

Queue

Make sure to start your queue workers, see the laravel documentation for specifics. To test the worker can start use php flarum queue:work.

Queue options

The queue allows for several options to be added, retry_after, block_for and after_commit. You can set these by adding a queue array in the configuration:

return [
    (new Blomstra\Redis\Extend\Redis([
        'host' => '127.0.0.1',
        'password' => null,
        'port' => 6379,
        'database' => 1,
        'queue' => [
            'retry_after' => 120, // seconds
            'block_for' => 5, // seconds
            'after_commit' => true 
        ]       
    ]))
    ->useDatabaseWith('cache', 1)
    ->useDatabaseWith('queue', 2)
    ->useDatabaseWith('session', 3)
];

You can read up on the meaning of these options in the Laravel Documentation.

Updating

composer update blomstra/flarum-redis

FAQ

Why are there still files in storage/cache? Some code still relies on physical files being present. This includes the formatter cache and the view caches.
