I’m trying to setup a mongrel cluster. I’m relying on information collected from a number of sources but I’m relying heavily on [http://mongrel.rubyforge.org/docs/apache.html](http://mongrel.rubyforge.org/docs/apache.html). I have noted that a number of sources mention the necessity of having the mod\_balancer module installed in Apache. However, my primary source makes no mention of this; but instead, mentions only the requirement of having the mod\_proxy\_balancer module installed. I’m confused. In an effort to resolve the confusion, I’m hypothesizing that the references I’ve read to mod\_balancer were really just mal formed references to mod\_proxy\_balancer. I know, it’s a stretch, but I really don’t know how else to resolve the apparent conflict. Can someone please resolve the issue for me? Is there really a mod\_balancer module that needs to be installed; or, is the mod\_proxy\_balancer module sufficient? Thanks for any input. ``` ... doug ``` ---

What version of Apache? I use mod\_proxy\_balancer on 2.2.x. ---

> What version of Apache? I use mod\_proxy\_balancer on 2.2.x. Thanks for the input. I’m using Apache 2.2.3. If you could just please verify that you have a cluster working with the mod\_proxy\_balancer module installed and with no module identified as mod\_balancer installed, I think that would pretty much put the issue to bed for me. Thanks. ``` ... doug ``` P.S. I thought I had replied before; but, I guess something went amiss. Thanks again. ---

I have both 2.2.3 and 2.2.4 working with mongrel\_cluster. I posted my notes and comments on my blog at [http://www.rubyhead.com](http://www.rubyhead.com) (sorry about shameless self-promotion). Joon ---

I’m pretty sure your suspicion is right. mod\_proxy\_balancer is what you need. There is no mod\_balancer AFAIK. BTW, this works great and is easy to configure with mongrel\_cluster.
