HowTo Install Redmine on Heroku¶

• Install Redmine locally

git clone git://github.com/redmine/redmine.git
cd redmine
git checkout 1.4-stable
cp config/database.yml.example config/database.yml
# edit config/database.yml
bundle install
rake config/initializers/session_store.rb

• create an Heroku app

heroku create

• remove from .gitignore these lines

/config/initializers/session_store.rb
/public/plugin_assets
/Gemfile.lock
/Gemfile.local

• configure heroku to run bundle install without sqlite group, otherwise it will fail

heroku config:add BUNDLE_WITHOUT="sqlite" 

• seems that Heroku cedar stack still doesn't support BUNDLE_WITHOUT so we have to comment sqlite groups on Gemfile

# edit Gemfile, comment sqlite groups
bundle install
git add Gemfile Gemfile.lock
git commit -m "remove sqlite gem from bundle" 

• commit changes and push to Heroku

git add -A
git commit -m "changes for heroku" 
git push heroku 1.4-stable:master

• migrate and populate database

heroku run rake db:migrate
heroku run rake redmine:load_default_data
