I've tried looking inside ./log in the rails application directory and there is nothing in any of the log files there. I've also tried looking at the web server logs themselves, and the access.log file shows an access to / and a request for the favicon, but nothing else, and the error.log is completely blank. I have run rails console and checked that I can do some basic things with my application. For example: >> rails console Loading development environment (Rails 3.0.3) irb(main):001:0> @p = Present.find(1) => #

The default Rails log level is info in production mode and debug in development http://stackoverflow.com/questions/26289738/rails-3-how-to-show-stack-trace-in-server-logs-for-500-internal-server-error-wh and test mode. To change the default log level, use config.log_level = :warn # In any environment initializer So, apparently, you need to modify your production environment initializer config to use :debug log level. However, this will cause logs to grow rapidly. If you encounter bugs, you should be solving them in development mode. In production it's common to tune the app just to fail silently with not-so-descriptive error message in case of an error. For hunting down environment-specific bugs, it's suggested to use a production-like staging enviromnent. share|improve this answer answered Oct 10 '14 at 0:07 D-side 6,3042936 Thanks! Is there a way to provide stack traces only on certain types of errors, e.g., 500 errors? –Crashalot Oct 10 '14 at 0:28 @Crashalot not sure, error 500 is an answer to a large number of problems. You could rescue specific exceptions in controller and print stack trace explicitly (I guess?) as suggested here: stackoverflow.com/questions/4260778/… –D-side Oct 10 '14 at 0:48 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

I installed passenger gem like this: sudo gem install passenger rvmsudo passenger-install-apache2-module and I configured apache settings as what the installation message says.
