How To Install Grafana K6 on Rocky Linux 8.5

In today’s guide we will teach you on how to install Grafana K6 on Rocky Linux 8.5. Before moving into the installation step, we will ask you some fundamental knowledge about what is actually K6? So, Grafana K6 is a free, open-source load testing tool to doing easily performance testing and productive dor engineering teams. You can use K6 freely without spend money to use it, since it free open-source software (FOSS), developer-centric, and extensible.

You can know the stability and reliability of your system performance after doing test with Grafana K6. Currently Grafana k6 is maintenanced and developed by Grafana Labs and open-source software community. So, you can catch performance regressions and issues found on your system previously. Using K6 you can also build resilient and scalable applications.

PRE-REQUISITES:

* VPS, Cloud, or Bare-Metal Server
* Running under Linux-Based Operating System
* Server IPv4 Address with Superuser Privileges (Root Access)
* Gnome Terminal for Linux Desktop
* PuTTy SSH Client for Windows or Mac
* Powershell for Windows 10/11

1.) Adding Fedora/CentOS Repository

K6 are available for some operating system like Windows, Linux and Mac or even you can run Grafana K6 on Docker container and a standalone binary. From this step we will use a Fedora/CentOS repository to install Grafana K6 on Rocky Linux 8.5. You can use a yum or dnf command.

$ dnf install https://dl.k6.io/rpm/repo.rpm

2.) Install Grafana K6

Simply run the following command to install Grafana K6 on your Rocky Linux machine.

$ dnf install k6

3.) Running K6 on Local Tests

Before doing in production environment, you can running local test with Grafana K6. We will write simple local script to make K6 running on local system. Simply create a file called a script.js and then paste the following code into script.js file.

import http from 'k6/http';
import { sleep } from 'k6';

export default function () {
http.get('https://test.k6.io');
sleep(1);
}

Then don’t forget to save above file and it will make K6 running with your machine resource. However, you can also run the test on your cloud server with the same methods.

4.) Let’s Run K6

After that simply run the following command to working K6 on your machine.

$ k6 run script.js

And the output as below or similar with this one.

CONCLUSIONS:

You have successfully in setting up Grafana K6 on Rocky Linux 8.5. You can do it on your self, either it run on local system or cloud compute like AWS or GCP.
