How To Implement SSL Termination With HAProxy on Ubuntu 14.04

Introduction

This tutorial will show you how to implement SSL termination with HAProxy on Ubuntu 14.04. SSL termination is the process of removing the SSL encryption from incoming traffic and forwarding it to the backend servers in plain HTTP. HAProxy is a powerful open-source load balancer and proxy server that can handle SSL termination and load balancing efficiently.

Prerequisites

Before you start, make sure you have the following prerequisites:

  • An Ubuntu 14.04 server
  • Root access to the server
  • HAProxy installed on the server
  • A domain name and SSL certificate
  • The backend servers that will receive the traffic

Step 1: Install SSL Certificate on the Server

To implement SSL termination with HAProxy, you need to install the SSL certificate on the server. You can obtain the SSL certificate from a trusted Certificate Authority or create a self-signed certificate. Once you have the SSL certificate, copy the certificate and private key to the server. 

				
					$ sudo mkdir /etc/haproxy/certs
					$ sudo cp /path/to/cert.crt /etc/haproxy/certs/
					$ sudo cp /path/to/cert.key /etc/haproxy/certs/

Step 2: Configure HAProxy for SSL Termination

Next, you need to configure HAProxy for SSL termination. Open the HAProxy configuration file in your favorite text editor: 

				
					$ sudo nano /etc/haproxy/haproxy.cfg

Find the frontend section and add the following lines: 

				
					frontend https_frontend
					bind *:443 ssl crt /etc/haproxy/certs/cert.pem
					mode http
					default_backend app_servers

Save and close the file.

Step 3: Configure the Backend Servers

Now, you need to configure the backend servers that will receive the traffic. Open the HAProxy configuration file again: 

				
					$ sudo nano /etc/haproxy/haproxy.cfg
