Capistrano: RSolr：：Error：：HTTP-404在重新索引Solr时未找到

Question

我没有发现任何可能有助于解决我的问题的具体例子。在我更新Rails 4和Ruby 2之前，我曾让太阳黑子宝石与Capistrano一起工作。如果能帮助处理这个错误，我们将不胜感激。

Gemfile:

gem 'sunspot_rails', :github => 'hsbt/sunspot', :branch => 'enabled-rails4'
gem 'sunspot_solr', :github => 'hsbt/sunspot', :branch => 'enabled-rails4'

.gitignore

solr/pids
solr/default

config/deploy.rb

namespace :deploy do
  task :start do ; end
  task :stop do ; end
  task :restart, :roles => :app, :except => { :no_release => true } do
    run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
  end

  desc "Migrate Database"
  task :migrate_db do
    run "cd #{current_path} && rake db:migrate RAILS_ENV=production"
    run "touch #{current_path}/tmp/restart.txt"
  end

  desc "Create Solr Directory"
  task :setup_solr_data_dir do
    run "mkdir -p #{shared_path}/solr/data"
  end
end

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 sunspot-solr start --port=8983 --data-directory=#{shared_path}/solr/data --pid-dir=#{shared_path}/pids > /dev/null 2>&1 || true"
  end
  desc "stop solr"
  task :stop, :roles => :app, :except => { :no_release => true } do
    run ("cd #{current_path} && RAILS_ENV=#{rails_env} bundle exec sunspot-solr stop --port=8983 --data-directory=#{shared_path}/solr/data --pid-dir=#{shared_path}/pids > /dev/null 2>&1 || true")
  end
  desc "reindex the whole database"
  task :reindex, :roles => :app do
    stop
    run "rm -rf #{shared_path}/solr/data"
    start
    run "cd #{current_path} && yes | RAILS_ENV=#{rails_env} bundle exec rake sunspot:solr:reindex"
  end
end

after "deploy", "deploy:cleanup", "deploy:migrate_db",'deploy:setup_solr_data_dir', 'solr:start', 'solr:reindex'

Answer 1

看起来您的Solr服务器不响应您期望的端点。您的URL似乎是：localhost:8983/solr/default (处理程序在该URL下面是/update )。

那里有Solr端点吗？你能手动访问吗？

如果没有，我建议将开始命令更改为记录到一个文件，而不是/dev/null，并查看您得到了哪些异常。
