Integrate Redis with Magento 2

 Description: Here I have explained, How to install and Integrate Redis with Magento.

Install Redis using apt command 

# apt-get install redis

After installation start and enable redis service 

# systemctl start redis

#systemctl enable redis

# systemctl status redis

Verify the installation using redis-cli command 

We can integrate redis with magento 2 ways, 

1> Edit the  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'
       )
    )
  )
),

2> Also configure same using command line as follow

# php bin/magento setup:config:set --cache-backend=redis --cache-backend-redis-server=127.0.0.1 --cache-backend-redis-db=10 --page-cache=redis --page-cache-redis-server=127.0.0.1 --page-cache-redis-db=11 --session-save=redis --session-save-redis-host=127.0.0.1 --session-save-redis-log-level=3 --session-save-redis-db=12
