sudo apt update sudo apt full-upgrade sudo apt install build-essential tcl
- Set up redis:
- Download latest copy via this link or with this
curl -O http://download.redis.io/redis-stable.tar.gz
- Create a temporary folder for it in say your
/home/username/redis-stable
directory - Move into created folder and extract it
