Preconfigured Ruby on Rails with Assembla Tickets

This page describes how to set up and deploy to staging and production servers.

Required server software

You need nginx or apache, ruby, rails, mongrel. For Debian/Ubuntu server execute:

apt-get install nginx ruby1.8 rdoc1.8 irb1.8
apt-get install sudo subversion gcc make libstdc++6-dev ruby1.8-dev libmysql-ruby
cd /tmp
wget http://rubyforge.org/frs/download.php/29548/rubygems-1.0.1.tgz #from http://rubyforge.org/frs/?group_id=126
tar xzf rubygems-1.0.1.tgz
cd rubygems-1.0.1 && ruby setup.rb
gem install rails -v=2.0.2 -y
gem install mongrel -y
apt-get install librmagick-ruby # if you need image magick support 

Edit the deploy.rb capistrano script

Adjust your application settings in config/deploy.rb

• Replace all my_project string with your application_name.
• Set username and password for your repository by modifing scm_username and scm_password variables.
• Set your stage and production servers in role statements

Install capistrano gem:

gem install capistrano -y

Configure server, first time

Execute to setup application directories on servers:

cap deploy:setup

Create a folder /etc/rails/<application_name>
Create production db

# mysqladmin create <application_name>_production
# mysql
> GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP,ALTER,INDEX ON <application_name>_production.* TO <app_user>@localhost IDENTIFIED BY 'Str0ng-Passw0rd!';
> FLUSH PRIVILEGES;

Copy to above folder database.yml and configure production db
Copy nginx.conf from the file tab to the /etc/nginx/ folder and modify it to sweet your needs and reload config

/etc/init.d/nginx reload

Run on local computer:

cap deploy
cap deploy:migrate

Note: To deploy to production servers, use:

ruby script/production_deploy
export PRODUCTION=1 && cap deploy:migrate
# or execute on the server:
rake db:migrate RAILS_ENV=production

Setting up continuous integration

You will need to install capistrano gem on deploy machine:

gem install capistrano -y

Copy deploy_project.sh from Files tab to machine, checkout your project in ~/projects folder and setup a cron job with command: crontab -e
