Any ideas? Doing this on the command line on my remote server works
instantly.

BTW: I’ve successfully migrated to capistrano by following the steps
mentioned on the RoR blog entry. Easy! I can see this tool becoming
quite handy over time.
For some reason I have never been able to determine, lighttpd does
not like to be restarted via capistrano. Sometimes it hangs (as
you’re observing) and other times it appears to finish successfully,
but lighttpd never gets restarted.
I’ve never observed this behavior with any other application–just
lighttpd. Many other people have observed this as well. I wish I knew
of a workaround you could try, but this has really stumped me for a
long time.
You might want to look into using external fastcgi processes, instead
of lighttpd-spawned ones, so that you can restart the fcgi’s without
having to restart lighttpd. Other than that, I’m not sure what to you
tell you.
I’m still on ST, but all of my Rails apps are served by lighttpd spawned
fastcgi
processes. And on every one of them ./script/process/reaper is all I
ever need
to do, to reload my apps code. In fact, the only ST change I needed to
make was
setting it to just “run” not “sudo”. The rest just flat worked.

Thanks Jamis! Is there a quick way to see what exactly cap is doing? If
it means anything, I’m running ruby 1.8.4 rails 1.0 and lighty 1.4.8
I indeed would like to use externally spawned processes (reaper/spinner)
but I need to think about how to do this because my setup is a bit
awkward and I initially wasn’t going to bore you with that… Please
feel free to ignore this question as it’s kind of OT
I’m trying to run several apps using one installation. I have the app
installed in /w/tennis
Then I have individual club sites
/sites/club1
/sites/club2
/sites/club3
All these are plain symlinks to /w/tennis - except the CSS and some
images directories which should remain unique per site.
lighty.conf has this for each site (= vhost):
“bin-path” => “/sites/”+var.appname+"/public/dispatch.fcgi",
But capistrano wants to restart a different process:
executing “sudo /w/tennis/current/script/process/reaper”
servers: [“ror1.tienhuis.nl”]
[ror1.tienhuis.nl] executing command
** [out :: ror1.tienhuis.nl] Couldn’t find any process matching:
/w/tennis/current/public/dispatch.fcgi
command finished
I could use this in lighty.conf and reference the only real
dispatch.fcgi:
“bin-path” => “/w/tennis/public/dispatch.fcgi”
But then the environment gets screwed because Rails loads the wrong
paths.
So basically I’m a bit lost as two how to deploy multiple sites using
one “base installation”. If anybody has any good pointers, please let me
know!

The problem here is that the reaper doesn’t know what the name of
your dispatcher is. It tries to grep the process list to find a
matching one, and the default selection criteria are failing.
If you know some unique string for finding the dispatcher processes
in the list of running processes, you can write your own restart task:
I first used your clever “kill-grep” command which worked, but then I
looked closely at the reaper script and indeed saw it already has built
in support for finding other processes than the standard
public/dispatch.fcgi in the app directory. I now use this:
task :restart, :roles => :app do
send(run_method, “#{current_path}/script/process/reaper -d mystring”)
end
Where “mystring” identifies part of the path to dispatch.fcgi
This works great, it finds all relevant processes and restarts them.
Thanks a lot!
