[Cruisecontrolrb-users] CruiseControl in Daemon mode?

[Billy Kimble]

Guys,

I recently installed CruiseControl and I love it. So much that I want  
to run it on its own server to handle all of my building needs. I  
installed it, added projects, ran it, and everything was groovy. I  
decided to stick the process in the background via:

./cruise start &

And it put it in the background just fine too. Everything was kosher  
until I tried logging out of my server. CruiseControl seemed to not  
want to relinquish control of my SSH connection. I thought perhaps it  
was a fluke on my connection so I just forcefully disconnected and  
tried triggering CC to build, which failed with the following message:

It appears that CruiseControl always wants a console to write to. I  
thought this was because of WEBRICK so I forced it to start in Daemon  
mode. Unfortunately that did not work and I am now at a loss. Is  
there something special I need to do to get CruiseControl to build  
projects in the background, so I can start it up as a service and let  
it do its work?  I am running CentOS 5 and Ruby 1.8.6. Any insight  
would be greatly appreciated.
