Capistrano Tasks to setup and interact with SolR and SunSpot

solr_deploy_interactions.rb

namespace :deploy do
  # Ask whether to reindex before restarting Passenger
  task :restart, :roles => :app, :except => {:no_release => true} do
    solr.reindex if 'y' == Capistrano::CLI.ui.ask("\n\n Should I reindex all models? (anything but y will cancel)")
    run "touch #{File.join(current_path, 'tmp', 'restart.txt')}"
  end

  desc 'create shared data and pid dirs for Solr'
  task :setup_solr_shared_dirs do
    # conf dir is not shared as different versions need different configs
    %w(data pids).each do |path|
      run "mkdir -p #{shared_path}/solr/#{path}"    
    end
  end


  desc 'substituses current_path/solr/data and pids with symlinks to the shared dirs'
  task :link_to_solr_shared_dirs do
    %w(solr/data solr/pids).each do |solr_path|
      run "rm -fr #{current_path}/#{solr_path}" #removing might not be necessary with proper .gitignore setup
      run "ln -s #{shared_path}/#{solr_path} #{current_path}/#{solr_path}"
    end
  end
end

after 'deploy:setup', 'deploy:setup_solr_shared_dirs'
# rm and symlinks every time we finished uploading code and symlinking to the new release
after 'deploy:update', 'deploy:link_to_solr_shared_dirs'


# Tasks to interact with Solr and SunSpot
namespace :solr do
  desc "start solr"
  task :start, :roles => :app, :except => { :no_release => true } do
    run "cd #{current_path} && RAILS_ENV=#{rails_env} bundle exec rake sunspot:solr:start"
  end
  desc "stop solr"
  task :stop, :roles => :app, :except => { :no_release => true } do
    run "cd #{current_path} && RAILS_ENV=#{rails_env} bundle exec rake sunspot:solr:stop"
  end

  desc "stop solr, remove data, start solr, reindex all records"
  task :hard_reindex, :roles => :app do
    stop
    run "rm -rf #{shared_path}/solr/data/*"
    start
    reindex
  end


  desc "simple reindex" #note the yes | reindex to avoid the nil.chomp error
  task :reindex, roles: :app do
    run "cd #{current_path} && yes | RAILS_ENV=#{rails_env} bundle exec rake sunspot:solr:reindex"
  end
end

seems nice, I will try this.

My setup task is not being executed, should I add this in config/deploy.rb? how?

I had to change this part:

run "mkdir #{current_path}/solr"
%w(solr/data solr/pids).each do |solr_path|
  run "rm -fr #{current_path}/#{solr_path}" #removing might not be necessary with proper .gitignore setup

Also, to because shared folders were not being created I used:

before 'deploy:update', 'deploy:setup_solr_shared_dirs'

I am having this:

 Error - RSolr::Error::Http - 500 Internal Server Error - retrying...

when reindexing.
