![]() ![]() What you will need for this, beside a little bit of experience with Linux operating system and some basics with networking, are four virtual machine nodes, which can be rented on Hetzner or DigitalOcean for as little as few bucks a month.Īll nodes have to have an extra network adapter, for communication/replication between the nodes, and separation of nodes from the Internet for security reasons. In this tutorial, we will install and configure a cluster of database servers, running Percona XtraDB (Percona is a fully compatible, drop-in replacement for MySQL), version 5.7, and HAProxy high availability load balancing proxy server which will handle all the traffic directed to the database nodes. ![]() Instead, using clusters of database servers becomes a viable variant, especially with virtual machine nodes becoming available for as little as 2.5$ a month for a single node.Ĭonfiguration of such clusters ain’t exactly a walk in the park though, and aim of this tutorial is to change that, well as much as possible at least. With our websites increasingly richer with data, and apps that reach millions of users overnight, it often ain’t enough anymore to have a single database server handling all the traffic.
