How To Install and Secure Redis on Ubuntu 18.04

Redis.sh

#!bin/sh

sudo apt update
sudo apt install redis-server

#Open this file with your preferred text editor. Inside the file, find the supervised directive. This directive allows you to declare an init system to manage Redis as a service, providing you with more control over its operation. The supervised directive is set to no by default. Since you are running Ubuntu, which uses the systemd init system, change this to (systemd):

sudo nano /etc/redis/redis.conf
  Add this (supervised systemd)
  
sudo systemctl restart redis.service
sudo systemctl status redis

#Extra desirable Settings

sudo systemctl disable redis

redis-cli
  ping
  Output
PONG

set test "It's working!"  
  Output
OK

get test
  "It's working!"
  
exit

#Securing Redis Installation

sudo nano /etc/redis/redis.conf

  #On the 'bind' section, change the IP address with your own internal network IP address.

bind INTERNAL-IP-ADDRESS  (127.0.0.1)

#Password Authentication. Uncomment the 'requirepass' section

requirepass G@kfse-labs321@#$
