Step-by-Step Guide: Installing wrk (HTTP Benchmarking Tool) on Amazon Linux

CloudGrains — Sat, 13 Dec 2025 10:32:11 +0000

If you're working with auto-scaling, load testing, or performance tuning on AWS, then wrk is one of the most powerful yet lightweight benchmarking tools you can use.

However, Amazon Linux doesn’t provide wrk via yum, so you must build it from source.
In this guide, I’ll walk you through a clean and reliable installation process — perfect for EC2 users.

🧠 What Is wrk?
wrk is a modern HTTP benchmarking tool capable of generating significant load from a single machine.
It uses:

multithreading
event-driven architecture (epoll/kqueue)
Lua scripting for advanced testing
This makes it ideal for testing:
API performance
Auto-scaling groups
Load balancers
Backend throughput

✅ Prerequisites
You’ll need:

An Amazon Linux / Amazon Linux 2 EC2 instance

sudo access

Basic yum packages (which we install anyway)

🛠 Step-by-Step Instructions to Install wrk on Amazon Linux

1️⃣ Install Development Tools & Dependencies
Amazon Linux requires build tools to compile wrk:

sudo yum groupinstall -y "Development Tools"
sudo yum install -y git

This installs:

gcc
make
automake
binutils
git
and other build dependencies

2️⃣ Clone the wrk Repository
Download the official wrk source code from GitHub:

git clone https://github.com/wg/wrk.git cd wrk

This brings you into the project directory, ready for building.

3️⃣ Build wrk Using make
Compile:

make

The process is fast — you'll get a binary named wrk inside the same folder.

4️⃣ Move wrk to Your PATH
Move the binary to a system-wide location such as /usr/local/bin:

sudo mv wrk /usr/local/bin/

Now you can run wrk globally from any shell.

🎯 Final Command Summary
Here’s the complete installation sequence:

sudo yum groupinstall -y "Development Tools"
sudo yum install -y git
git clone https://github.com/wg/wrk.git
cd wrk
make
sudo mv wrk /usr/local/bin/

🚀 How to Use wrk
Once installed, try generating load:

wrk -t12 -c400 -d30s http://your-server-endpoint/

Explanation:

-t12 → number of threads

-c400 → number of open connections

-d30s → duration of test

URL → your target API or load balancer

🏁 Summary
Installing wrk on Amazon Linux is straightforward once you install development tools.
You simply:

Install build dependencies

Clone wrk

Compile it

Move the binary

After that, you can benchmark anything from APIs to auto-scaling groups with a single command.

K9s Installation Script for Amazon Linux / RHEL-Based Systems-

CloudGrains — Fri, 12 Dec 2025 12:10:34 +0000

This guide provides a shell script to automatically install the latest version of K9s, a terminal UI for managing Kubernetes clusters.

🚀 What This Script Does

Updates system packages

Installs required dependencies (wget, tar)

Fetches the latest K9s release version from GitHub

Downloads and installs the K9s binary

Cleans up leftover files

Verifies the installation

#!/bin/bash

# Update packages and install necessary dependencies
sudo yum update -y
sudo yum install -y wget tar

# Fetch the latest K9s version
K9S_VERSION=$(curl -s https://api.github.com/repos/derailed/k9s/releases/latest | grep tag_name | cut -d '"' -f 4)

# Download the latest K9s release
wget https://github.com/derailed/k9s/releases/download/${K9S_VERSION}/k9s_Linux_amd64.tar.gz

# Check if the download was successful
if [ $? -ne 0 ]; then
  echo "Failed to download K9s. Please check the version number and URL."
  exit 1
fi

# Extract the tarball and move the binary to /usr/local/bin
tar -xzf k9s_Linux_amd64.tar.gz
sudo mv k9s /usr/local/bin/

# Clean up
rm k9s_Linux_amd64.tar.gz

# Verify installation
k9s version

🧩 Usage Instructions

Save the script to a file

nano install_k9s.sh

Paste the script and save.

Make the script executable

chmod +x install_k9s.sh

Run the script

sh install_k9s.sh

✅ Verify Installation

Run the following command:


## k9s version

You should see the installed version printed.
