Question

I want to run few commands when i start application on server.

So, i wrote such script in config/deploy.rb:

desc "Start sphinx" 
  task :start_sphinx, :roles => :app do
    run "cd #{current_path} && bundle install --without development test && bundle install --deployment && chmod 777 -R #{current_path}/tmp/ && rake thinking_sphinx:configure && rake thinking_sphinx:start"
  end

But when i print

$ cap deploy

It doesn’t work. So, please, tell me what is wrong!

Here is log from terminal:

$ cap deploy
  * executing `deploy'
  * executing `deploy:update'
 ** transaction: start
  * executing `deploy:update_code'

Answer 1

It looks like you are missing the callback. For example, if you wanted to run your script after the code has been updated, you can use an after callback like

after "deploy:update_code", "start_sphinx"

For more info on callbacks, check out the callbacks rdoc
