Install HAProxy Ubuntu 16.04

In this tutorial we’ll learn how to install HAProxy on Ubuntu 16.04. We will also install and configure its prerequisites. HAProxy is an open-source solution that works TCP- and – HTTP-based software. This alternative provides transparent connections, server offloading, policy authorities, connection limiting, and more. If you’re afraid adding such a coating to your web servers will be too complex, panic not. Installing and setting up HAProxy is remarkably easy.

I recommend to use a minimal Ubuntu server setup as a basis for the tutorial, that can be a virtual or a root server image with an Ubuntu 16.04 minimal install from a web hosting company or you use our minimal server tutorial to install a server from scratch.

Install HAProxy Ubuntu 16.04

Step 1. First, ensure your system and apt package lists are fully up-to-date by running the following:

apt-get update -y
apt-get upgrade -y

Step 2. Installing HAProxy.

First, you will need to add the new repository with the following command:

sudo add-apt-repository ppa:vbernat/haproxy-1.7

Run the below command to install HAProxy:

sudo apt update
sudo apt install -y haproxy

Once the installation is done successfully, you can make sure of that by running the below command on the terminal to ensure that HAProxy is working:

haproxy -v

Result:

HA-Proxy version 1.7.8-1ppa1~xenial 2017/07/09

Step 3. Configure HAProxy.

Open the configuration file, for example, using nano with the command underneath:

nano /etc/haproxy/haproxy.cfg

Add the following sections to the end of the file. Replace the <server name> with what ever you want to call you servers on the statistics page and the <private IP> with the private IPs for the servers you wish to direct the web traffic to:

frontend http_front
 bind *:80
 stats uri /haproxy?stats
 default_backend http_back

backend http_back
 balance roundrobin
 server <server1 name> <private IP 1>:80 check
 server <server2 name> <private IP 2>:80 check

After making the configurations, save the file and restart HAProxy with the next command:

systemctl restart haproxy

Congratulation’s! You have successfully install and configure HAProxy on your Ubuntu 16.04 server. Thanks for using this tutorial for installing HAProxy on Ubuntu system.
