Install Kapacitor on Ubuntu 20.04

In this tutorial, we will show you how to install Kapacitor on Ubuntu 20.04 LTS. For those of you who didn’t know, Kapacitor is an open-source framework for processing, monitoring, and alerting time series data. Kapacitor can process both stream and batch data from InfluxDB, acting on this data in real-time via its programming language TICKscript.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Kapacitor real-time streaming data processing engine on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.


  • A server running one of the following operating systems: Ubuntu 20.04, 18.04, and any other Debian-based distribution like Linux Mint or elementary OS.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
