i found answer.. some of the software was outdated on my nginx server for this i run some of the command.

sudo apt update

and 

sudo apt upgrade

after this you need to edit redis configuration file. in my case file was at sudo nano /etc/redis/redis.conf

here you have to confirm that you have replaced #maxmemory with

maxmemory 128mb
maxmemory-policy allkeys-lfu

then restart the redis and php using

sudo service redis-server restart
sudo service php7.2-fpm restart

then go for test using the code given below:

redis-cli
ping
set test "It's working"
get test

this will show the result "it's working"

now use command exit to exit

congratulations, problem solved
