Memcached – Removing Redis from Laravel Project in Windows

My project will not start without Redis running. I get this message if I try to open a page without redis running in Laravel:

“No connection could be made because the target machine actively refused it. [tcp://127.0.0.1:6379]”

I’ve tried
1) php artisan config:cache,
2) php artisan clear:cache,
3) composer remove predis/predis
4) composer remove predis
5) removing instances of redis
6) uninstall redis through command line

Any help would be greatly appreciated! Thanks!

    If you don’t want to install any cache service like Redis or Memcached, you can use the file or database driver on Laravel.

    To change the cache driver you must change the CACHE_DRIVER variable your .env file to file, or modify the config/cache.php file.

    The default cache.php config file looks like this:

    /*
|--------------------------------------------------------------------------
| Default Cache Store
|--------------------------------------------------------------------------
|
| This option controls the default cache connection that gets used while
| using this caching library. This connection is used when another is
| not explicitly specified when executing a given caching function.
|
| Supported: "apc", "array", "database", "file",
|            "memcached", "redis", "dynamodb"
|
*/
'default' => env('CACHE_DRIVER', 'file'),

    The env() function get the data from environment variable defined on first parameter, and fallback to the value defined on second parameter. So if your .env file define a CACHE_DRIVER variable, it will ignore the second parameter value.

    I got the same issue just now. The error:

    "No connection could be made because the target machine actively refused it. [tcp://127.0.0.1:6379]"

    This means there is something in the app that still use redis for its service.

    1. Check controllers and/or models for redis connection or redis methods and remove all of those.
    2. On the config, you wanna check cache, database, queue and filesystem. To do this make sure your env file is clear of anything related to redis:
    // .env
CACHE_DRIVER=redis // change this to file
QUEUE_CONNECTION=redis // change this to sync

// I was using redis for azure cache and I missed this one because it was hard coded,
// now I placed it inside env file
AZURE_CACHE_STORE=redis // change this to file

// In fact u can skip commenting this out
#REDIS_CLIENT=predis
#REDIS_HOST=redis
#REDIS_PASSWORD=null
#REDIS_PORT=6379

    No need to comment or remove Redis in config/app.php

    If you are planning of simply switching out redis for later, no need to remove use Redis; in the files that will need it in the future. On production better remove these completely.

    Same with phpredis or predis, no need to remove them if you will use it for later otherwise.

    Key here is to check all your config to better have idea where whose redis things are or simply by using your text editor, just search all through the files with redis keyword.
