unicorn/nginx doesn't work after changing default capistrano deployment directory

Hi Everyone,

I installed a ruby on rails pre-packaged version to ubuntu 12.4. And use capistrano to deploy my app. I changed the default app directory from /home/rails to /var/www/apps/. The deployment was successful, but i got unicorn errors and the end result is timeout on the page. Please help me with this, this has confused me for quite a while, I can’t really figure out why.

solution for rails 3.2.x is to stop unicorn and uninstall rack 1.5.2:

service unicorn stop
gem uninstall rack -v 1.5.2

after that I have also uninstalled rack 1.5.2 dependencies:

gem uninstall actionpack-4.1.6
gem uninstall actionpack-4.0.2

, but I thing it is not necessary.

Than run bundle install and restart nginx:

service nginx restart

Finally start unicorn:

service unicorn start

It should work. After that I had to solve some other problems, but it were small things compare to this problem.

Cheers Kuba

so what’s the solution?

There’s your error: <br><blockquote>/usr/local/rvm/gems/ruby-2.0.0-p353/gems/bundler-1.3.5/lib/bundler/runtime.rb:33:in `block in setup’: You have already activated rack 1.5.2, but your Gemfile requires rack 1.4.5. Using bundle exec may solve this. (Gem::LoadError)</blockquote>
