Redis can be installed on the Ubuntu machines by using the command:-

sudo apt-get install Redis-server

If the user wants Redis to be installed as an object cache for Wordpress or any other PHP, then the following command can be used:-

sudo apt-get install php-redis

If the user wants to configure the Redis as a cache, /etc/Redis/redis.conf file needs to be updated, and the text editor nano can be used for this purpose.

sudo nano /etc/redis/redis.conf

Any text editor can be used.
