What is lsyncd?

lsyncd is a rsync-based tool that monitors specified directories (including subdirectories) for updates and modifications, and then syncs those changes to a specified destination. It is a lightweight command application that is easy to install and configure using the popular Lua language.

Introduction

All online businesses need to account for growth. As a business receives more visitors to its site, the underlying infrastructure needs to scale to provide the same level of performance that the visitors are accustomed to. Horizontal scaling, the addition of more servers rather than increasing the power of the existing servers, is an easy way to build our web servers' ability to handle a more significant amount of traffic and protect us against hardware failure. Ensuring that the additional web servers have the same files and data is a potentially time-consuming and challenging task. Automating that task using free, open-source software, such as lsyncd, is a way to ensure that we have a safe, secure, and repeatable method of copying files from one server to another.

Load balancing and replicating multiple servers has a great array of benefits, though orchestrating and keeping them in sync can be very tricky. Here, we will walk through some of the load balancing options available, as well as setting up a very basic one-way replication sync between two or more servers behind a load balancer.
