Question

clear cache on Ruby on Rails on Ubuntu (nginx + unicorn)

I set up a new Ruby on Rails on Ubuntu (nginx + unicorn) droplet. The only thing I did was change the html in the default home page (/home/rails/app/views/home/index.html.erb).

Now when I load and reload the home page at http://104.131.230.147/ it switches between the original home page and the new one. I have checked with others to see if the behavior is the same for them and it is.

I’ve tried rake tmp:cache:clear rake assets:clean

What other options are there?

I have this same problem with Django+Ubuntu. I’m thankful that at least restarting gunicorn gets a temporary fix. I can’t seem to find any solution to this and I’m amazed that more people don’t have this problem.

Where is the caching coming from? Also, where is this “config.action_controller.perform_caching = false” change made?

I have also had problems with caching running Unicorn with multiple worker processes. If you’re using config.cache_store = :memory_store in your environments/production.rb that could be the issue. In this case it appears that the memory store is duplicated across the workers. Try switching settings to

config.action_controller.perform_caching = false

and see if the behavior stops. If so, you probably need to use a different caching strategy. See http://guides.rubyonrails.org/caching_with_rails.html#cache-stores

Are you restarting the unicorn server after changing the file? Run:

service unicorn restart

Also make sure that a copy of the page isn’t being cached in /home/rails/public/
