Install haproxy and configure haproxy

Date Posted:25-02-2017

Assumption:

1. Ubuntu Server
2. Any custom Service. In our example, we will forward the port 8080 request to other server.

We are gonna explain on how to install haproxy on Ubuntu server. Additionally, we will show up on how to configure service which forwards a requests from haproxy to specific service.

Implementation:

Lets install haproxy on the server.

apt-get install haproxy

Start the service and enable the service on system startup.

systemctl start haproxy

systemctl enable haproxy

Configuration:

We don’t make any changes on default settings. This post uses all the default haproxy values.

Open haprxoy configuration and add the below mentioned lines. This will forward the request from  port 8080 request to server xx.xx.xx.xx port 8080

vi /etc/haproxy/haproxy.cfg

listen nameapp 0.0.0.0:8080
	mode http
	balance roundrobin
	server server1 xx.xx.xx.xx:8080 check

The above configuration forwards the port 8080 request from haproxy server to xx.xx.xx.xx.

balance roundrobin – This is used to balance the traffic between multiple servers incase multiple server added

Restart the service to make into effect.

systemctl restart haproxy

Verification:

Access the page using the port number on the browser and you can see the traffic will be routed to server1.
