I think that you need to install the PHP Redis Module in order for PHP to be able to communicate with Redis.

You could do that by running the following commands:

  • First, update your package manager cache by running:
sudo apt update
  • Then install the php-redis package:
apt install php-redis 
  • After that you should be able to see an .ini file for the php-redis module available at:

You might have to restart Apache in order for the new module to be picked up.

Hope that this helps!
