7 Getting Started

8 What you need A server running Ubuntu 8.10 A user on the server who can sudo and access your Git repository A beer (optional)

9 Install Plugins script/plugin install git://github.com/railsmachine/moonshine.git script/plugin install git://github.com/railsmachine/moonshine_ssh.git script/plugin install git://github.com/railsmachine/ moonshine_iptables.git Install any other Moonshine plugins you want script/generate moonshine Generates conﬁg/moonshine.yml and app/manifests/

10 Gems Make sure all of your gems are declared in environment.rb rake moonshine:gems Generates gems.yml You need to do this any time you add/remove/change the gems

11 Edit moonshine.yml :ruby: ree :application: ultranetweb :user: rails :time_zone: UTC :deploy_to: /srv/ultranetweb :domain: ultranetweb.com :domain_aliases: - www.ultranetweb.com - assets1.ultranetweb.com # The entries in shared_children are created in #{application}/shared :shared_children: - system - log - pids - conﬁg :repository: git@github.com:robotmode/ultranetweb.git

12 Edit moonshine.yml :local_conﬁg: - conﬁg/database.yml :ssh :port: 9022 :allow_users: - jarin - rails :apt_gems: :paperclip: - imagemagick :passenger: :max_pool_size: 3 :use_global_queue: true :mysql: :innodb_buffer_pool_size: 128M

13 Edit application_manifest.rb Located in app/manifests/ # Installs Rails, Apache, Passenger, the database from database.yml, Postﬁx, # Cron, logrotate and NTP. recipe :default_stack plugin :ssh recipe :ssh plugin :iptables recipe :iptables

14 Edit application_manifest.rb Located in app/manifests/ def application_packages send_weekly_emails = "/usr/bin/rake -f #{configuration[:deploy_to]}/ current/Rakefile mailer:send_weekly_emails RAILS_ENV=#{ENV['RAILS_ENV']}" cron 'notifications:send_weekly_emails', :command => send_weekly_emails, :user => configuration[:user], :minute => 0, :hour => 3, :weekday => 1 # Only run the following on the 'staging' stage using capistrano-ext. on_stage 'staging' do file '/etc/motd', :ensure => :file, :content => "!!! STAGING SERVER !!!" end end

15 Capify and go! capify . conﬁg/deploy.rb: server "ultranetweb.com", :app, :web, :db, :primary => true Add to git git add . && git commit -am "added moonshine" && git push Bootstrap! cap deploy:setup Deploy! cap deploy

16 Now, cap deploy will… Verify your system conﬁg on each deploy Run migrations Install gems …and their system dependencies! Pull down submodules Keep your system conﬁguration in version control!

17 But what about other servers? You can have per-server manifests for your app servers, database servers, memcache, etc. set :moonshine_manifest, 'memcached_manifest' By default, Moonshine sets your database auto-increment to 10 to allow for easier database sharding later Check the Moonshine Google Group for more info
