Why I got errors running redis in laravel app? - laravel

Question

I need to run laravel 5 app on my local Kubuntu 18 and I need to run redis server for this app
I installed and in file /etc/redis/redis.conf I uncommented line :
requirepass foobared
in .env I modified redis config :
REDIS_HOST=http://127.0.0.1:8000 # I run app with command : php artisan serve
REDIS_PASSWORD=foobared
REDIS_PORT=6379 # default port
I restarted redis and check status:
$ sudo service redis status

I see that file Can't open PID file not found above
But I have this file:
root#AtHome:/run/redis# ls -la
total 4
drwxr-sr-x 2 redis redis 60 Feb 26 14:32 .
drwxr-xr-x 38 root root 1160 Feb 26 14:32 ..
-rw-rw---- 1 redis redis 6 Feb 26 14:32 redis-server.pid
root#AtHome:/run/redis# cat redis-server.pid
22676
aand I got error on next command :
$ laravel-echo-server start
Error: The config file could not be found.
Is this errors as PID file was not found above?
How can it be fixed?
In composer.json :
"laravel/framework": "5.5.*",
"predis/predis": "^1.1",
MODIFIED # :
In /etc/redis/redis.conf I found
pidfile /var/run/redis/redis-server.pid
When I installed the ubuntu I installed /var on separate partition, so I have in /etc/fstab :
UUID=e531d8c5-530c-4533-a949-9fd5a62e0821 / ext4 errors=remount-ro 0 1
# /boot was on /dev/sdb1 during installation
UUID=23cc34a1-2be9-43b1-9c79-8e53af7bc799 /boot ext4 defaults 0 2
# /var was on /dev/sdb5 during installation
UUID=57c14b70-da85-4c5b-be6f-45174147d987 /var ext4 defaults 0 2
that is why /var/run/redis/redis-server.pid looks like /run/redis/redis-server.pid in my console command.
I do not know can that be key of this problem? How can it be salved ?

Yes, redis started and it shows in status command :
Active: active (running)
I see error message
Feb 26 13:52:09 AtHome systemd[1]: redis-server.service: Can't open PID file /var/run/redis/redis-server.pid
I do not know how critical is it ?
I need to run in the root of my app laravel-echo-server for redis working
but I got error :
$ laravel-echo-server start
Error: The config file could not be found.
I suppose that 2) depends on 1), but not sure, I am new in redis and very common
knowledge about laravel-echo-server...
MODIFIED # 3 :
Searching how test redis I found how made tests, but looks like not all works properly :
app_root$ redis-cli
127.0.0.1:6379> set greetings "Hello World!"
(error) NOAUTH Authentication required.
127.0.0.1:6379> get greetings
(error) NOAUTH Authentication required.
127.0.0.1:6379> exit
app_root$ sudo systemctl restart redis

app_root$ redis-cli
127.0.0.1:6379> get greetings
(error) NOAUTH Authentication required.
127.0.0.1:6379>
But I am still not sure if it is reason that I got error running laravel-echo-server
Thanks!
