A scalable MediaWiki Bundle

This bundle deploys Mediawiki, memcached, MySQL, and an haproxy. It requires a
minimum of 5 units. The mediawiki charm is placed behind the proxy so that you
can point DNS at the proxy and then scale the mediawiki unit up and down.

Usage

All you should do after deployment is expose haproxy, you can do this via the
GUI or via the CLI:

juju expose haproxy

To scale out mediawiki itself:

juju add-unit mediawiki

There's no need to configure memcached, it is included in this bundle to use
mediawiki already. The MySQL database is set up in a master->slave
configuration so you can scale the database as well with:

juju add-unit mysql-slave
