Setup Guide for HAProxy on RHEL 9
High traffic can put a lot of pressure on a single server, and that is where a tool like HAProxy becomes valuable. It helps you spread requests across several servers so your applications stay responsive and stable. This guide explains what HAProxy does and shows you how to set it up on RHEL nine in a clear, easy way.
Introduction to HAProxy
HAProxy is a free tool that helps share incoming traffic across several servers so your site or app stays fast and stable. It receives each request and sends it to a healthy server, keeping the backend hidden from users. It also checks server health and avoids servers that stop responding, which helps reduce downtime. Its simple setup fits many types of applications and environments.
Steps to Install and Configure HAProxy on RHEL 9
Step 1: Install HAProxy
Update your system and install the haproxy package. After the installation, check the package details to make sure it is installed correctly.
Step 2: Back up and open the config file
Make a copy of the default haproxy.cfg file so you have a safe backup. Then open the main configuration file in a text editor to start making changes.

Step 3: Add your frontend and backend
Inside the config file, set up a frontend that listens on port eighty. Then add a backend section and list the servers that should receive the traffic. You can use roundrobin and basic health checks for a simple setup.
Step 4: Update firewall and SELinux settings
Allow traffic on the needed ports through the firewall. If SELinux blocks connections, switch it to permissive mode for now or create a rule later that allows HAProxy to work with your web servers.
Step 5: Start and enable HAProxy
Start the HAProxy service and enable it so it runs automatically whenever the server starts.
Step 6: Check that everything is working
Open your server’s IP address in a browser to see if traffic reaches your backend servers. Then open the stats page you set in the config to view live details about how HAProxy is handling requests.
