$ rake ts:start Failed to start searchd daemon. Check ../log/searchd.log. Failed to start searchd daemon. Check ../log/searchd.log Be sure to run thinking_sphinx:index before thinking_sphinx:startAlmost always is the case for me that searchd is already running / orphaned and needs to be killed. Run
$ps -ax | grep searchdshows that its already running

Yes, this can be achieved through redirecting rails log to standard output.
Write these at your console prompt:
ActiveRecord::Base.logger = Logger.new(STDOUT)
ActiveRecord::Base.connection_pool.clear_reloadable_connections!
Furthermore, you can put these lines in ~/.irbrc file, so that each time you don't need to manually write these 2 lines:
require 'rubygems'
if ENV.include?('RAILS_ENV') && ENV["RAILS_ENV"] == 'development'
ActiveRecord::Base.logger = Logger.new(STDOUT)
ActiveRecord::Base.connection_pool.clear_reloadable_connections!
end
