Question 121508 in Redis Question posted in
The official documentation can be found here.

Symfony Redis keeps connecting to localhost instead of defined host in env file

We have a new Symfony setup with Redis as cache mechanism. We want to connect to a specific host, not the default localhost. On production, the ./bin/console debug:dotenv gives the correct REDIS_HOST. This is configured in our .env and .env.local.php.

The error we get is:

Connection refused: tcp:127.0.0.1/6379

This is our config:

services.yml

services:
    Redis:
        # you can also use RedisArray, RedisCluster or PredisClient classes
        class: PredisClient
        calls:
            - connect:
                  - '%env(REDIS_HOST)%'
                  - '%env(int:REDIS_PORT)%'
    SymfonyComponentHttpFoundationSessionStorageHandlerRedisSessionHandler:
        arguments:
            - '@Redis'
            - prefix: sp_ss_
            - ttl: 1800

cache.yml

framework:
    cache:
        app: cache.adapter.redis
        default_redis_provider: 'Redis'
        pools:
            site.cache:
                adapter: cache.app

And our .env file:

APP_ENV=prod
APP_SECRET=****
MESSENGER_TRANSPORT_DSN=redis://redis.local:6379/messages
REDIS_HOST=redis.local
REDIS_PORT=6379
REDIS_URL=redis://redis.local:6379

    There might be hidden other .env files. May you check out the files list with the following code at the root of your projects? Are there other env files such as .env.prod, .env.local?

    ls -lah

    The Symfony’s documentation suggest to use "calls -> connect", but it’s used only when you was defined the class as ‘Redis’. When you use ‘PredisClient’, you need to use the settings bellow:

    "config/services.yaml"

        Redis:
        # you can also use RedisArray, RedisCluster or PredisClient classes
        class: PredisClient
        # See all parameters here: https://github.com/predis/predis/wiki/Connection-Parameters#list-of-connection-parameters
        arguments:
            - host: '%env(REDIS_HOST)%'
            - port: '%env(int:REDIS_PORT)%'
            # uncomment the following if your Redis server requires a password
            # - password: '%env(REDIS_PASSWORD)%'

    I’m also using the ‘PredisClient’ and after to change to ‘arguments’ the connection was worked here.
