How to Implement Redis in Drupal 8?

For one of my project, I have implemented the Redis module in Drupal 8. I have used the following configurations as follows:

• First I download Redis module for a Drupal 8 environment and stored it in 'modules/contrib' directory and enabled the same.
• For the working of Redis module we need its libraries, so first you have to download the phpredis php extension library from https://github.com/nicolasff/phpredis. Extract the entire contents of the archive into the 'libraries/' folder.

For the working of Redis in local server we have add php extension to our local server. For this follow the steps for seting up Redis Server

• After that update the settings.php file with the following code:

  $settings['redis.connection']['interface'] = 'PhpRedis';
      // Host ip address.
      $settings['redis.connection']['host']      = '127.0.0.1';
      $settings['cache']['default'] = 'cache.backend.redis';
      // Redis port.
      $settings['redis.connection']['port']      = '6379';
      $settings['redis.connection']['base']      = 12;
      // Password of redis updated in php.ini file.
      $settings['redis.connection']['password'] = "password";
      $settings['cache']['bins']['bootstrap'] = 'cache.backend.chainedfast';
      $settings['cache']['bins']['discovery'] = 'cache.backend.chainedfast';
      $settings['cache']['bins']['config'] = 'cache.backend.chainedfast';
  

• Create services.yml and add the below code in it.

  services:
    # Cache tag checksum backend. Used by redis and most other cache backend
    # to deal with cache tag invalidations.
    cache_tags.invalidator.checksum:
     class: Drupal\redis\Cache\RedisCacheTagsChecksum
     arguments: ['@redis.factory']
     tags:
       - { name: cache_tags_invalidator }
  
    # Replaces the default lock backend with a redis implementation.
    lock:
      class: Drupal\Core\Lock\LockBackendInterface
      factory: ['@redis.lock.factory', get]
  
    # Replaces the default persistent lock backend with a redis implementation.
    lock.persistent:
      class: Drupal\Core\Lock\LockBackendInterface
      factory: ['@redis.lock.factory', get]
      arguments: [true]
  
    # Replaces the default flood backend with a redis implementation.
    flood:
      class: Drupal\Core\Flood\FloodInterface
      factory: ['@redis.flood.factory', get]
  

Hope this is useful.
