Gentoo, Pacemaker, and Apache

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...
