Rails 应用程序：Solr 在执行搜索时抛出 RSolr::Error::Http - 404 Not Found

【中文标题】Rails 应用程序：Solr 在执行搜索时抛出 RSolr::Error::Http - 404 Not Found【英文标题】：Rails app: Solr throwing RSolr::Error::Http - 404 Not Found when executing search 【发布时间】：2013-11-14 14:38:48 【问题描述】：非常迷茫，因为我没有对一直有效的搜索进行任何更改，但不知何故我已经休息了。对于 Rails 来说相对较新，错误输出并没有给我足够的调试细节。
下面的相关代码 - 询问您是否想查看其他内容。
home.html.slim（搜索表单摘录）
= form_tag search_venues_path, method: :get, id: 'search' do |f|
.search-fields.span16
p = text_field_tag :q, '', placeholder: "Search for coffee, hotel, etc", class: 'span7 search-field'
p = text_field_tag :zip, '', placeholder: "Zip code or city name", class: 'span4 search-field'
p = submit_tag "Find it", class: "btn-main span4"
br
= hidden_field_tag :latitude, ''
= hidden_field_tag :longitude, ''
p.current_location.hidden.offset1
a Use my current location
VenuesController.rb（带搜索功能的节选）
def search
if params[:zip].blank? && params[:latitude].blank?
flash[:notice] = 'You must include a location to search.'
return redirect_to(root_path)
end
@venues = VenueSearch.search(params)
#@json = Venue.all.to_gmaps4rails
end
VenueSearch.rb
def self.search(params)
if params[:zip].present?
logger.info "The zip code is present"
logger.debug(Geocoder.coordinates(params[:zip]))
lat, long = Geocoder.coordinates(params[:zip])
else
lat = params[:latitude]
long = params[:longitude]
end
fake_distance = 20 * 0.6214 # 1.5 miles
Venue.search(include: [:venue_category, :venue_subcategory]) do
fulltext params[:q].gsub(/[^\s\w]/, ''), minimum_match: 2 do
boost_fields name: 5.0, name_without_punc: 5.0, category: 3.5, subcategory: 3.5, tags: 4.0
end
paginate page: params[:page]
order_by_geodist :location, lat, long
with(:location).in_radius(lat, long, fake_distance)
end
end

【问题讨论】：
您指出的 Solr 端点是什么？是否启动并运行？ @SrikanthVenugopalan 我已将我的 sunspot.yml 添加到问题的底部。你指的是这个吗？抱歉，如果没有，我真的很喜欢 Solr。 太棒了.. 我假设您可以从出现此错误的服务器上点击http://localhost:8983？
@SrikanthVenugopalan - 我之前可以在这里找到管理员：localhost:8983/solr/#/development - 但我将我的 solr gem 更新到 2.1.0，现在收到以下错误：screencast.com/t/rtXpIBbRisPq。有什么想法吗？
嗯 - 告诉我你的 Solr 实例没有启动，因为 SolrConfig 中的错误。你能看看你的 Solr (Jetty) 日志吗？它应该有一个堆栈跟踪
【参考方案1】：
我在从 2.0.0 升级到 sunspot 2.1.0 时遇到了同样的问题。
我通过在development: 块上将以下行添加到sunspot.yml（在我的rails 应用程序中的配置下）解决了这个问题（test 和production 可能需要一个）
solr_home: solr
所以我的 SOLR 安装在 rails-app-dir/solr 下，配置在 conf 下。
【讨论】：
此时此刻，你是我的英雄。这修复了我的开发环境中的 404 错误！我将尽快进行暂存，以在该环境中测试相同的添加。太感谢了。在此之前，我的搜索实际上也被破坏了——由于某种原因，位置搜索不起作用。如果我发布一个关于它的 SO 条目，我想知道你是否不介意找我？ :) 可悲的是，这并不能在生产中解决它:(关于如何让它工作的任何想法？此时我将你提到的用于开发的相同修复添加到生产块中。你知道吗需要为生产提供的具体参考？ 好吧 - 基本上这需要指向您的 SOLR 文件所在的位置。使用locate 或find shell 命令来解决这个问题。您基本上是在寻找数据/生产目录。寻找sunspot-solr-production.pid 的好人选
刚刚注意到有关铁轨的一些信息 - 太阳黑子数据文件。似乎 2.1.0 将数据存储在 gems - 目录下。我认为在 2.0.0 上它在 rails app solr/ 下。
虽然这并不能完全解决我的问题，但它让我知道从 2.0 迁移到 2.1 是我的问题。将 Gem 回滚到 2.0 并能够解决我的问题。现在我只需要弄清楚如何成功迁移到 2.1。【参考方案2】：
@Marko Taponen 的解决方案为我工作了一段时间，但现在我回来了，因为这个问题再次出现在我的 rpsec/capybara 测试中。
这是为我解决的问题：
在命令行上：
bundle exec rake sunspot:solr:stop
完成此操作后，我再次运行测试，它成功了。！
【讨论】：
【参考方案3】：我一直在寻找这个问题的答案，并了解 SOLR 管理页面为什么会崩溃。这是将 sunspot solr 从 2.0.0 升级到 2.1.0 时针对此问题的解决方案：
将此条目添加到 sunspot.yml 的开发部分：solr_home: solr 就像以下示例一样...
development:
solr:
hostname: localhost
port: 8982
log_level: INFO
path: /solr/development
solr_home: solr
【讨论】：
【参考方案4】：这些是您应该遵循的终端命令来解决您的问题：
ps aux | grep solr 获取 solr 进程 ID
sudo kill <ID>,<ID>是你从1中找到的ID
rm -r <path/to/solr>，删除项目中的 solr 目录以删除所有以前的索引
RAILS_ENV=production bundle exec rake sunspot:solr:start
将路径更改为 /solr/default 内 config/sunspot.yml
development:
solr:
hostname: localhost
port: 8982
log_level: INFO
path: /solr/default
RAILS_ENV=production bundle exec rake sunspot:solr:reindex
砰！问题解决了！我希望。
【讨论】：
这完全有效！我明天必须演示我的应用程序，在我找到你的答案之前它完全坏了！！ 为什么我不能多次为同一个答案投票？？？谢谢，谢谢，谢谢！！！ 工作就像一个魅力！我猜关键是将索引名称更改为/solr/default 任何想法如何使用自定义索引名称？
谢谢！解决方案是 /solr/default 部分:)
在我的情况下，我必须设置路径：/sorl，没有默认或开发【参考方案5】：
有人检查了您的项目的 ./solr 目录吗？
如果是这样，请将其删除，运行 rails g sunspot_rails:install 然后再次启动您的服务器。
这个已经咬了我两次了。
【讨论】：
【参考方案6】：还要检查是否从您的 gem 文件或应用程序根目录中的 solr 目录加载了 schema.xml！您最终可能会多次更改 schema.xml，但加载的文件可能是错误的。
【讨论】：
【参考方案7】：development:
solr:
hostname: localhost
port: 8982
log_level: INFO
path: /solr
auto_index_callback: after_commit
auto_remove_callback: after_commit
