Gentoo, Pacemaker, and Apache

March 22, 2011

I’ve been playing around with creating HA Load Balancing Proxy servers with Apache on top of Pacemaker today.

Since Gentoo does it’s configuration a little differently than most distributions, this hit a hurdle.

Gentoo puts some Apache command line options in a file /etc/conf.d/apache2 these decide the vohosts that start and other “-D” values. Without these apache will fail to start.

As Pacemaker doesn’t know about this file, or these values, apache was failing to spawn, and I was getting an error.

Simply copying the -D values, into the HTTPOPTS variable in the /usr/lib/ocf/resource.d/heartbeat/apache file fixed the problem:

HTTPDOPTS=”-D DEFAULT_VHOST -D INFO -D SSL -D SSL_DEFAULT_VHOST -D LANGUAGE -D STATUS -D PROXY”

Now I have two load balancers, running in an active/passive configuration…

The Journey to IPv6 – Part One – The Request

March 9, 2011

Hopefully this will be the first in a series of posts exploring the testing and implementation of IPv6 in the network I administer. My ultimate goal is to have our public facing web servers dual stack, and accessible by both IPv4 and IPv6.

For the moment, I have a request in to our ISP for a /56 block which should be actioned in the next couple of days.

Wish me luck!
