Hi y’all;

A quick note to announce the release of mongrel\_cluster, a gem\_plugin  
for Mongrel. This plugin provides commands for managing multiple  
Mongrel processes behind a reverse-proxy server and load balancer.

To install:  
gem install mongrel\_cluster

Configure (use -h to options):  
mongrel\_rails cluster::configure

Start:  
mongrel\_rails cluster::start

I’ve posted a quick how-to on my blog:  
[http://fluxura.com/articles/2006/04/24/easy-mongrel-clustering-with-](http://fluxura.com/articles/2006/04/24/easy-mongrel-clustering-with-)  
mongrel\_cluster

This is the first of many open source releases to support simplified  
Ruby on Rails application deployment and is an extraction from my  
work on Rails Machine. Stay tuned for Capistrano tasks, rc scripts,  
and other good stuff. Give it a try and let me know how it works.

Thanks,  
Bradley Taylor

Very nice Bradley. Thanks!

Nice one Bradley!

This seems to get around the problems I was having with mongrel +  
capistrano where a new deployment and symlink update was not picked up  
by the mongrel processes (they were keeping the old symlink target on  
restart)

All I had to do was change in mongrel\_cluster.yml  
  
cwd: /path/to/application/releases/20060411090306  
  
which was automatically inserted by cluster::configure, to  
  
cwd: /path/to/application/current

That’s just from my preliminary testing so let me know if I’ve missed  
something, but failing any major problems this is going into  
production!

Many thanks,  
Dan

I’ve found a few bugs with respect to use with Capistrano and I  
should have fixes shortly. The next release, mongrel\_cluster 0.2,  
will fix the bugs and add a Capistrano task library. Thanks for  
trying it out!

I used it last night to deploy mongrel into production for one of my  
sites. I documented the process last night and although I am not the  
best capistrano user out there you might want to have a look at the  
tasks I wrote.

To be honest though, it was an absolute piece of cake thanks to your  
work.

Cheers,  
Dan
