To reduce server load I'm wanting to start sphinx on demand as I have
over 80 websites all wanting to use sphinx but usually only 10 active
at any one time.
Obviously if ts is not running I get a connection refused exception
from riddle so all I need to do is trap that exception and start the
server.
To achieve this I have the following in a searches controller.
def index
@search_results = CustomMenu.search(params[:search], :include
=> :custom_page)
begin
if @search_results.blank?
flash[:notice] = 'Sorry, no search results found'
end
rescue Riddle::ConnectionError
start_search_engine
@search_results = CustomMenu.search(params[:search], :include
=> :custom_page)
end
end
def start_search_engine
Search.start_sphinx
end
and the search module looks like this
class Search
def self.start_sphinx
"rake thinking_sphinx:rebuild RAILS_ENV=#{Rails.env}"
res = "rake thinking_sphinx:start RAILS_ENV=#{Rails.env}"
puts("@@@@ Start sphinx #{res}")
end
end
However the start_sphinx method does not actually work though the
output returned in the puts statement shows
@@@@ Start sphinx rake thinking_sphinx:start RAILS_ENV=development but
the connection is refused in the view.
Sphinx will start if I run the rake task from the command line.
Any ideas as to what the best solution for this problem might be would
be greatly appreciated.
