  19. 19. Capfile where the fun starts load 'deploy' if respond_to?(:namespace) # cap2 differentiator load 'includes/recipes/stages' load 'includes/recipes/mikamai' load 'includes/recipes/drupal' load 'includes/recipes/overrides' load 'includes/recipes/devs' # SCM Stuff configure to taste, just remember the repository set :repository, "git@github.com:mikamai/app.git" set :scm, :git set :branch, "master" set :repository_cache, "git_master" set :deploy_via, :remote_cache set :scm_verbose, true set :keep_releases, 3
  20. 20. includes/recipes where we put the “Good Stuff”™
  21. 21. devs.rb let’s tell capistrano about ourselves task :intinig do set :local_mysqldump, "/usr/local/mysql/bin/mysqldump" set :local_db_user, "root" set :local_db_password, "youwishItoldyou" set :local_db_name, "app_db" end task :paolo do set :local_mysqldump, "/Applications/MAMP/Library/bin/mysqldump" set :local_db_user, "root" set :local_db_password, "paolo" set :local_db_name, "stefano" end
  22. 22. drupal.rb change capistrano default behavior load File.dirname(__FILE__) + '/drupal/db' load File.dirname(__FILE__) + '/drupal/configure' after 'deploy:setup', 'drupal:setup' after 'deploy:symlink', 'drupal:symlink' before 'deploy:start', 'drupal:db:import:production' before 'deploy:restart', 'drupal:configure:stage' before 'deploy:start', 'drupal:configure:stage' namespace :drupal do task :setup, :except => { :no_release => true } do sudo "mkdir -p #{shared_path}/files" sudo "chmod a+w #{shared_path}/files" sudo "mkdir -p #{shared_path}/dumps" sudo "chown -R #{user}:#{user} #{deploy_to}" end task :symlink, :except => { :no_release => true } do sudo "ln -s #{shared_path}/files #{latest_release}" end end
  23. 23. drupal/configure.rb a small hack for multiple stages namespace :drupal do namespace :configure do task :stage do source = "#{latest_release}/sites/default/settings.#{stage_name}.php" dest = "#{latest_release}/sites/default/settings.php" sudo "cp #{source} #{dest}" end end end
  24. 24. drupal/db.rb mysql grinding namespace :local do desc "Dumps the local database" task :default, :roles => :db do raise RuntimeError.new("failed dump") unless system "#{local_mysqldump} -u #{local_db_user} -- password=#{local_db_password} #{local_db_name} > dump.local.sql" end namespace :upload do desc "Dumps and uploads the local database" task :default do drupal::db::dump::local::default put(File.read("dump.local.sql"), "#{shared_path}/dumps/dump.local.sql") run "mysql -u #{db_user} --password=#{db_password} #{db_name} < #{shared_path}/dumps/ dump.local.sql" end end end
  25. 25. drupal/db.rb mysql grinding / 2 namespace :remote do desc "Dumps the remote database" task :default, :roles => :db do filename = "#{Time.now.to_i.to_s}.dump.sql" run "cd #{shared_path}/dumps; #{remote_mysqldump} -u #{db_user} --password=#{db_password} #{db_name} > #{filename}" run "cd #{shared_path}/dumps; bzip2 #{filename}" end namespace :download do desc "Dumps and downloads the remote database" task :default do drupal::db::dump::remote::default latest end desc "Downloads the latest database dump" task :latest, :roles => :db do dumps = capture("ls -xt #{shared_path}/dumps").split.reverse get("#{shared_path}/dumps/#{dumps.last}", "./#{dumps.last}") end end end
  26. 26. mikamai.rb fix problems on our servers before 'deploy:restart', 'mikamai:permissions:fix' before 'deploy:start', 'mikamai:permissions:fix' namespace :mikamai do namespace :production do task :symlink, :except => { :no_release => true } do sudo "rm -rf /var/www/#{application}" sudo "ln -s #{latest_release} /var/www/#{application}" end end namespace :permissions do task :fix, :except => { :no_release => true } do sudo "chown -R www-data:www-data #{latest_release}" end end end
  27. 27. overrides.rb do as we say not as we do namespace :deploy do task :finalize_update, :except => { :no_release => true } do sudo "chmod -R g+w #{latest_release}" if fetch(:group_writable, true) end task :cold do update start end task :restart do end task :start do end end
  28. 28. stages.rb one for everyone set :application, "cool_app" desc "deploy to development environment" task :development do set :stage_name, "development" role :web, "danton.mikamai.com:8888", :primary => true role :db, "danton.mikamai.com:8888", :primary => true set :user, "drupal" set :password, "secret" set :remote_mysqldump, "/usr/bin/mysqldump" set :deploy_to, "/var/apps/#{application}" set :db_user, "dbuser" set :db_password, "supersecret" set :db_name, "appname" end
