Then, restart HaProxy server to reload the changes: $ sudo service haproxy restart Remember to replace the backend server private IP address with the actual private IP addresses for your Alibaba ECS instances. Option httpchk HEAD / HTTP/1.1 Host:localhost Http-request add-header X-Forwarded-Proto https if Http-request set-header X-Forwarded-Port % We can now go ahead and add the backend configuration details as follows: backend ourwebsiteendpoint At the end of the text, we have specified ourwebsiteendpoint as the directive where our endpoints are located. The bind parameter tells HaProxy to listen to port 80 for connections. So, towards the end of the file, add the content below: frontend ourwebsitefrontend However, the file does not contain any load balancing information, and we need to create the frontend and backend settings for our servers. These two sections should work by default. The defaults section handles login- and error-related issues. The global section lists different parameters such as user and the group under which HAproxy runs.

This is where we are going to install HaProxy Server.Д«efore we do this, we need to update the package information index using the command below: $ sudo apt-get update SSH to the first ECS instance using its Public IP address. Step 1: Configuring haproxy-server (Frontend)

HaProxy-server : Port 80 http and port 32600 for statistics.

backend-server2 : private IP address 172.16.0.2, public IP address 198.18.0.2ДЄlso, you need to create a security group that allows the following ports for the servers:.

haproxy-server : public IP address 198.18.0.1.

We will still need to connect to all three instances via public IP addresses through SSH to install all required applications.ДЇor the sake of simplicity, we will assume the following IP addresses and hostnames for the instances: We will also require the public IP address for the frontend server for accessing your web application or website. We will use Alibaba Cloud ECS instance private IP addresses for the two endpoints. We will be using one ECS instance as the frontend and two more as endpoints where the load is going to be distributed.

A non-root user that can perform sudo privileges on all three instances.

HAProxy works by distributing concurrent connections to multiple backend servers based on a load balancing algorithm.

It is used by the world's highly trafficked websites, including Twitter, Tumblr, Amazon Web Service, and GoDaddy to spread incoming requests across multiple endpoints.

HAProxy (High Availability Proxy) is an intelligent software solution that offers load balancing and a high level of uptime performance for TCP- and HTTP-based applications.
