Laravel changes

After this you can change the laravel configuration file, since now we only need 2 databases, they can be 0 and 1

REDIS_PORT=6380
REDIS_DB_NUM=0
REDIS_DB_CACHE=1

And change the laravel-echo-server.json file also:

...

databaseConfig": {
    "redis": {
            "port": "6380",
            "host": "127.0.0.1",
            "options": {
                    "db": 1
            }
    },

...
