Apache

Running a redundant apache server does not require much from apache itself, but rather the underlying filesystem and a proxy in front of it. The filesystem is important, so the website and its php sessions can be shared between the servers. For this we will use GlusterFS. The proxy in front of apache will be a combination of HA-proxy and Corosync.

In this setup we will configure 2 apache servers.

Software

apt-get install apache2 php php-mysql

Filesystem

Configure your system as a Gluster Client, so you have /var/www on a GlusterFS. Make a simple webpage, that shows something uniq about the system. This way we can later on see which server HA-proxy redirects to,

index.php

   1 <?php
   2 echo gethostname();
   3 ?>
