It looks like the restart of backgroundrb failed to start backgroundrb
because restart's stop-backgroundrb failed (nothing running, nothing
to stop), and quit the task.
If that's the case, perhaps a start_backgroundrb task is in order? I'm
controlling backgroundrb via god, and calling them from capistrano w/
the following task set:
$ cap -T |grep backgroundrb
cap restart_backgroundrb # restart backgroundrb servers
cap start_backgroundrb # start backgroundrb servers
cap stop_backgroundrb # stop backgroundrb servers
# Backgroundrb Server TASKS
%w(start stop restart).each do |cmd|
desc "#{cmd} backgroundrb servers"
task "#{cmd}_backgroundrb".to_sym, :roles => :app do
run "sudo #{god} #{cmd} backgroundrb"
end
end
hope that helps,
Erik
