Listen Port (Read/Write): Port for read/write mode. Server Address: IP Address for our HAProxy server. The information that we need to introduce is: Go to ClusterControl -> Select Cluster -> Cluster Actions -> Add Load Balancer. How to Install and Configure HAProxy with ClusterControlįor this task, we’ll assume that you have ClusterControl installed (on-prem or in the cloud) and it’s currently managing your databases. Now, let’s see how ClusterControl can make this task in an easy way. For example: listen haproxy_readĭefault-server port 9201 inter 2s downinter 5s rise 3 fall 2 slowstart 60s maxconn 64 maxqueue 128 weight 100 listen haproxy_readĪs we mentioned before, there are several parameters to configure here, and this configuration depends on what we want to do. We want to create an HAProxy listener to balance the read traffic between the three nodes. In the first step, you must choose the EC2 instance operating system. Go to the Amazon EC2 section, and press on Launch Instance. Creating an Amazon EC2 Instanceįor this example, we’ll assume that you have an Amazon AWS account. Now, let’s see how to create an EC2 instance to deploy HAProxy there. It also allows you to quickly scale capacity, both up and down, as your computing requirements change.Īmazon EC2 supports different operating systems like Amazon Linux, Ubuntu, Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, Fedora, Debian, CentOS, Gentoo Linux, Oracle Linux, and FreeBSD. It gives you complete control of your computing resources and allows you to set up and configure everything within your instances from the operating system up to your applications. An Overview of Amazon EC2Īmazon Elastic Compute Cloud (or EC2) is a web service that provides resizable compute capacity in the cloud. If any of the destinations stops responding, it is marked as offline, and the traffic is sent to the rest of the available destinations. HAProxy is an open source proxy that can be used to implement high availability, load balancing, and proxying for TCP and HTTP based applications.Īs a load balancer, HAProxy distributes traffic from one origin to one or more destinations and can define specific rules and/or protocols for this task. In this blog, we’ll take a look at the popular database load balancer HAProxy and how to deploy it to Amazon AWS both manually and with ClusterControl’s help. To deploy it, you don’t need a physical server as you can deploy it in the cloud making it easier and faster. To achieve a split, you will need to use a load balancer to perform the task.Ī load balancer can redirect applications to available/healthy database nodes and then failover when required. Depending on the application, however, this may not be possible (if you have a single configurable endpoint). When this situation happens it’s useful to distribute the traffic across multiple servers, thus improving performance. When traffic to your database increases day-after-day it can start to become hard to manage.
