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|GlusterFS]]. The proxy in front of apache will be a combination of [[HA-proxy|HA-proxy]] and [[Corosync|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
