Install Kandan on Ubuntu

If you’re looking to install Kandan chat application on a private stand alone server or to develop locally, then here is the path you must follow.

git clone https://github.com/kandanapp/kandan.git 
cd kandan

Lots of the gems require other libraries:

sudo apt-get install ruby1.9.1-dev ruby-bundler libxslt-dev libxml2-dev libpq-dev libsqlite3-dev

Some gems build native extensions:

sudo apt-get install gcc g++ make

For development-mode

sudo apt-get install nodejs # (execjs needs an execution environment)
gem install execjs # (Could possibly be added to the gemfile in the assets group)

Install the required gems:

bundle install

You can use the default database.yml to get started in development. For production you’ll need to edit config/database.yml to add something like this:

  adapter: postgresql
  host: localhost
  database: kandan_production
  pool: 5
  timeout: 5000
  # You might need these depending on your Postgres auth setup.
  username: kandan 
  password: something

Now, bootstrap the install. you can omit the db:create step if you have already created the DB referenced above:

bundle exec rake db:create db:migrate kandan:bootstrap

If you plan to serve the app directly from Thin (rather than through a proxy), you will need to configure Rails to serve assets in the production environment. In config/environments/production.rb:

config.serve_static_assets = true

Start the rails server

bundle exec thin start

Your app should be up and running now. The default admin user is Admin with password kandanappadmin, or you can sign up as another user.
