Hi guys, I’m trying to deploy my application but when I run cap  
deploy:cold I get the following error:

—ERROR--------------

—SCRIPT/SPIN--------

/home/app/current/script/process/spawner -p 8000 -i 3

Anyone have any ideas?

Make sure script/spin has the correct permissions on it (at least  
readable and executable) for the user that is being used to execute  
it.

Hi Jamis,

How could I do this with capistrano?

Many people are doing this with a task that gets called after the code  
is pushed out, something like this:

after “deploy:update\_code”, :fix\_script\_perms

task :fix\_script\_perms do  
run “chmod 755 #{latest\_release}/script/spin”  
end

Alternatively, if you’re using subversion, you can set the  
svn:executable property on script/spin and be done with it.

Thanks Jamis.

Is there a way to change the path of ruby in the dispatch files using  
capistrano? As I need to change #!D:/ruby/bin/ruby to #!/usr/bin/ruby

I’m sure you could use some sed or awk magic to do it, but neither of  
those tools are my forte, so I’ll defer to someone with more  
experience to give you a more detailed answer.

Why don’t you add this to your deploy.rb file instead of using spinner  
script?

set :mongrel\_conf,  
“/var/www/#{application}/current/config/mongrel\_cluster.yml”

namespace :deploy do  
namespace :mongrel do  
[:stop, :start, :restart].each do |t|  
desc “#{t.to\_s.capitalize} the mongrel appserver”  
task t, :roles =\> :app do  
#invoke\_command checks the use\_sudo variable to determine how to  
run th$  
invoke\_command “mongrel\_rails cluster::#{t.to\_s} -C  
#{mongrel\_conf}”, 😊  
end  
end  
end

desc “Custom restart task for mongrel cluster”  
task :restart, :roles =\> :app, :except =\> { :no\_release =\> true } do  
deploy.mongrel.restart  
end

desc “Custom start task for mongrel cluster”  
task :start, :roles =\> :app do  
deploy.mongrel.start  
end

desc “Custom stop task for mongrel cluster”  
task :stop, :roles =\> :app do  
deploy.mongrel.stop  
end  
end

It works great for me … I haven’t tried achieving the same with your  
approach because “I didn’t get it” when reading about it for the first  
time… This works, because it overrides the default tasks for restarting  
mongrel. So it works with “cap deploy” and of course with “cap  
deploy:mongrel:start” etc.

Maybe I’m wrong… would be grateful if someone commented on the  
differences between spinner script and this.

bye!
