- Install HAProxy Enterprise Edition (HAPEE), which is a long-term maintained HAProxy package accompanied by a well-polished collection of software, scripts, configuration files and documentation which significantly simplifies the setup and maintenance of a completely operational solution; it is particularly suited to Cloud environments where.

HAProxy-WI will install SELinux policy, if this does not happen then install the package: sudo yum install haproxy-wi-selinux Fail2ban Installing If you use RPM you have not do anything. This tutorial will guide you through setting up haproxy on a fresh Ununtu box using Ansible. We will follow the steps outlined in How To Use HAProxy to Set Up HTTP Load Balancing on an Ubuntu VPS. Except: instead of doing it manually, this time, we will do it with. An available option is the HAProxy appliance, one of the first third-party load balancing partners working with VMware the networking side of things for Tanzu. This post will take a closer look at how to install HAProxy in VMware vSphere with Tanzu Kubernetes.
In this tutorial you will be shown how to scale your MySQL database, and balance traffic across all slave nodes.
Your application load has grown too large for your backend database server, and you need a solution to do so that his highly available and balanced.
You could use DNS round-robin load balancing, however, your DNS service is unlikely to know the state your backend service. If an endpoint goes down, DNS would continue directing traffic to it.
A better solution is to use a TCP proxy service, such as HAProxy.

Deploy MySQL Servers
Creating a new MySQL cluster is not covered in this post. However, the instructions are available in a previous post called How to Create MySQL Master Slave Clusters.
You will need at least one master node and one slave node to get started.
Define the Backend Service in HAProxy
The first step is to create a service proxy for the backend read-only database servers. The service is what your the application we target as the database read endpoints.

An example haproxy configuration is shown below. The configuration in the example creates a frontend service called app1_read_db. We bind it to a network interface and port on the haproxy host.
The second part is to define our backend service, which is where we place the read-only databases. We create a server entry for each, give it a name, and set its network endpoint.
Round Robin MySQL Load Balancing
Robin-robin load balancing a simple model for balancing traffic across your backend servers. Traffic will will rotate between each server in sequential order. For example, if you have three servers defined as your backend, then the first connection would go to server 1, the second connection would go to server 2, and the third connection would go to server 3.
Use Case: The round-robin model works best in environments where all servers are of the same spec.
Cons: HAProxy will not monitor the amount of open connections to your servers. Since not all database connections are equal, there is a chance the one or more of your servers become overwhelmed with traffic, while others sit idle.
Least Connections MySQL Load Balancing

The least connections model will attempt to priorities backend servers with the least amount of connections. HAProxy will monitor how many open connections each database server has. New traffic will be directed to servers with the least amount of connections first.
Simplifying Configuration using Listen

In the two examples above there is a frontend and a backend configuration for each service. We can combine these two into a single listener configuration. This is a common practice for proxying TCP network services.
