#Lsyncd-AWS-AutoScaling

Lsyncd auto configuration that works with Amazon Web Services (AWS) Auto Scaling.

Lsyncd is Live Syncing (Mirror) Daemon.

It does the following:

1. Monitors auto scaled instances that are attached to a load balancer.
2. Automatically configures Lsyncd to sync across all attached instances to a load balancer.
3. Monitors Lsyncd and make sure Lsyncd is always up and running, while Lsyncd does the syncing of files from master to auto-scaled slaves.

##Pre-requisites & assumptions

Lsyncd-AWS-AutoScaling requires the following to be set up and running on your master server:

1. lsyncd is set up on your master.
2. Passwordless SSH is possible from master to slave via the use of a private key.

This project is tested on Lsyncd v2.0.7 and on Ubuntu 12.04.1 LTS instances.

##Set Up

1. Set up Composer
2. composer install to install the dependencies.
3. cp config.php.default config.php and edit accordingly.

##Run

php monitor.php

That's all.

It is recommended to set it to run via crontab to ensure that it is run periodically and automatically.
