Question

我想在服务器上启动应用程序时运行一些命令。

所以，我在 config / deploy.rb ：

中编写了这样的脚本

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

但是当我打印

$ cap deploy

它不起作用。所以，请告诉我有什么问题！

这是来自终端的日志：

看起来你错过了回调。例如，如果您想在代码更新后运行脚本，则可以使用后回调，如

after "deploy:update_code", "start_sphinx"

有关回调的更多信息，请查看callbacks rdoc

Rails 3 - 在cap：deploy之后脚本不运行
