Redis is an open source software which is used for advanced key-value cache and store. It is often referred to as a data structure server. If we running Redis server in our system, EtherCalc will prefer it over file-based storage to improve performance.

$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:rwky/redis
$ sudo apt-get update
$ sudo apt-get install redis-server

To check status:

$ redis-cli ping
