# Introduction

If your Redis service is running on your web server, it is highly recommended that you use Unix sockets instead of TCP ports to communicate with your web server.

Based on the Redis official benchmark, you can improve performance by upto 50% using unix sockets (versus TCP ports) on Redis.

Of course, unix sockets can only be used if both your Laravel application and Redis are running on the same server.

# How To Enable Unix Sockets

First, create the redis folder that the unix socket will be in and set appropriate permissions:

$ sudo mkdir -p /var/run/redis/
$ sudo chown -R redis:www-data /var/run/redis

Next, add the unix socket path and permissions in your Redis configuration file (typically at /etc/redis/redis.conf):

unixsocket /var/run/redis/redis.sock
unixsocketperm 770

Finally, set your corresponding env variables to the socket path as above:

REDIS_HOST=/var/run/redis/redis.sock
REDIS_PORT=null
REDIS_SCHEME=unix

Ensure that you have your config/database.php file refer to the above variables (notice the scheme addition below):







 



















'redis' => [
    'client' => env('REDIS_CLIENT', 'phpredis'),
    
    'options' => [
        'cluster' => env('REDIS_CLUSTER', 'redis'),
        'prefix' => env('REDIS_PREFIX', Str::slug(env('APP_NAME', 'laravel'), '_').'_database_'),
        'scheme' => env('REDIS_SCHEME', 'tcp'),
    ],

    'default' => [
        'url' => env('REDIS_URL'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD', null),
        'port' => env('REDIS_PORT', '6379'),
        'database' => env('REDIS_DB', '0'),
    ],

    'cache' => [
        'url' => env('REDIS_URL'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD', null),
        'port' => env('REDIS_PORT', '6379'),
        'database' => env('REDIS_CACHE_DB', '1'),
    ],
],

# Skip Condition

This analyzer is skipped for local environments (if the skip_env_specific configuration option is set to true) or if your application does not use Redis.
