Thinking sphinx doesn't start - "Failed to start searchd daemon"

Question

I try to start thinking sphinx on my server but it doesn't want to work.

I do:

$ rake thinking_sphinx:index && rake thinking_sphinx:start

And i get:

Be sure to run thinking_sphinx:index before thinking_sphinx:start

My server's system is Ubuntu 10.04. Also, on my local machine (Mac OS X) it works perfect.

My sphinx.yml:

development:
  bin_path: "/usr/local/bin"
  searchd_binary_name: searchd
  indexer_binary_name: indexer

test:
  bin_path: "/usr/local/bin"
  searchd_binary_name: searchd
  indexer_binary_name: indexer

config/deploy.rb

#Add RVM's lib directory to the load path.
$:.unshift(File.expand_path('./lib', ENV['rvm_path']))

#Load RVM's capistrano plugin.    
require "rvm/capistrano"
require 'bundler/capistrano'
#require 'thinking_sphinx/deploy/capistrano'

set :user, "root"                                                             #If you log into your server with a different user name than you are logged into your local machine with, you’ll need to tell Capistrano about that user name.

I solved it. I had sphinx process in the background, so i just killed it:

$ ps -efa | grep sphinx
root     23823     1  0 14:12 ?        00:00:00 searchd --pidfile --config /vol/www/apps/ror_tutorial/releases/20120202111104/config/production.sphinx.conf
root     27069 20413  0 14:49 pts/1    00:00:00 grep sphinx
$ kill 23823 

Then i started sphinx:

$ rake ts:start RAILS_ENV=production
Started successfully (pid 27097).
