#capistrano-rails-server gem#

Capistrano-rails-server is a collection of capistrano recipes for setting up production server for RoR. The current testing environment is Ubuntu 12.04 LTS.

Components: RVM, Nginx, Passenger, Postgresql, Postfix

Add this line to your application's Gemfile:

gem 'capistrano-rails-server', :require => false

And then execute:

$ bundle install

Run $ cap init in your app folder if you don't have deploy.rb in your config dir (details here).

Then include these lines to the end of your deploy.rb:

# uncomment this if you need non en-US locale for postgresql server
#set :postgresql_locale, "ru_RU"
#set :postgresql_rebuild, true

# uncomment this if you want to overwrite default config templates
#set :templates, {
#  "nginx_passenger.erb" => File.expand_path("../templates/my_cool_nginx_template.erb", __FILE__),
#  ...
#}

# uncomment this if you need another version of Ruby
#set_default :rvm_ruby_string, "2.0.0-p353"
# 
# see other available params in documentation 
# https://github.com/Drakula2k/capistrano-rails-server


# you can remove any recipe if you don't need it
set :capistrano_rails_server, [:base, :nginx, :passenger, :postgresql, :postfix, :rvm, :check, :key]
require 'capistrano-rails-server'

Create admin group:

# addgroup admin

Create user for deployment:

# adduser yourappuser --ingroup admin

(Optional) Edit /etc/sudoers file if you don't want to enter user's password several time during recipes running (don't forget to undo it after installing!):

replace line

%admin ALL=(ALL) ALL

with

%admin ALL=(ALL) NOPASSWD:ALL

After that run command to install all software needed:

$ cap deploy:install

And configure it:

$ cap deploy:setup

Thats all, now you can deploy your app:

$ cap deploy
