Redirect loop problem with SSL

October 07, 2012 10:30PM
Hello, I am having a problem understanding exactly how to configure my nginx server to use SSL with Linode, RoR, Unicorn and spree ecommerce. This post will be kind of long, but this is just so you can see all the steps I have taken thus far. The first section will include all the steps I have taken to set up my linode instance. In this setup, the site displays, but I get the Redirect Loop when I try to log in. Someone suggested that I needed to set up separate server blocks for port 80 and port 443. After I did this (the nginx.conf for that set up will be at the end), every page gives me the Redirect loop. So, I clearly do not understand what I am doing and need a little nudge. Please help me.

--- error message ---

This webpage has a redirect loop

The webpage at https://50.116.18.21/login has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.

5. apt-get -y install curl git-core python-software-properties
6. add-apt-repository ppa:nginx/stable
7. apt-get -y update
8. apt-get -y install nginx
/*** Can I do the SSL stuff here??? ***/
#. mkdir /srv/ssl/
#. cd /srv/ssl
#. openssl req -new -x509 -days 365 -nodes -out /srv/ssl/nginx.pem -keyout /srv/ssl/nginx.key

9. service nginx start
10. apt-get -y install imagemagick
11. add-apt-repository ppa:pitti/postgresql
12. apt-get -y update
13. apt-get -y install postgresql libpq-dev
14. sudo -u postgres psql
15. \password
16. create user mayorio with password 'secret';

24. adduser deployer --ingroup admin
25. su deployer
26. cd
27. curl -L https://raw.github.com/fesplugas/rbenv-installer/master/bin/rbenv-installer | bash
28. vim ~/.bashrc # add rbenv to the top
29. put the following in the top:
--- begin snippet ---
export RBENV_ROOT="${HOME}/.rbenv"

if [ -d "${RBENV_ROOT}" ]; then
export PATH="${RBENV_ROOT}/bin:${PATH}"
eval "$(rbenv init -)"
fi
--- end snippet ---
30. . ~/.bashrc
31. rbenv bootstrap-ubuntu-10-04
32. rbenv install 1.9.3-p125
33. rbenv global 1.9.3-p125
34. gem install bundler --no-ri --no-rdoc
35. rbenv rehash
36. ssh git@github.com
37. switch back to local box
38. rails new mayorio -d postgresql
39. cd mayorio
*** 40 and 41 no longer necessary. they must have fixed it :)
40. edit Gemfile to add "gem 'cocaine', :git => 'git://github.com/thoughtbot/cocaine.git'" (make sure to do to newlines after for spree)
41. bundle install
*** see above ***
42. sudo -u postgres psql
43. create user mayorio with password 'secret';

48. bundle exec rake assets:precompile:nondigest
*** consider adding public/assets to .gitignore ***
49. edit .gitignore and add "/config/database.yml"
50. cp config/database.yml config/database.example.yml
51. git init
52. git add .
53. git commit -m "initial commit"
54. create github repo "mayorio"
55. git remote add origin git@github.com:mlybrand/mayorio.git
56. git push origin master
57. edit Gemfile to uncomment unicorn and capistrano lines
58. bundle
59. capify .
