我陷入了一个奇怪的问题，我正在寻找您的意见。
我的问题是：
在使用 Capistrano 在生产上部署我的应用程序后，当我进行 solr 重新索引时，它给了我以下错误：
$ bundle exec rake sunspot:reindex --trace
** Invoke sunspot:reindex (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute sunspot:reindex

从日志中可以清楚地看出，重新索引失败的原因有两个：
A. 无法创建核心：collection1
B. 在类路径中找不到资源“solrconfig.xml”
基于上述错误，以下是我尝试的技巧：
A. 检查 solr 的文件夹权限
B. 在 solr 中手动创建 collection1 并将 solrconfig.xml 复制到 /solr/collection1/conf 中。
C. 从 /data/APP_NAME/shared/bundled_gems/ruby/1.9.1/bundler/gems/sunspot-87e29212527f/sunspot_solr/solr 复制 lib 和 conf 文件夹并将其粘贴到 APP_NAME/solr/sunspot_rails 文件夹中。
但没有一个解决方案奏效。:-(
请建议。
[更新]：我的 Gemfile 看起来像这样：
gem "sunspot", "~> 1.3.3"
gem 'sunspot_rails', '~> 1.3.0'
gem 'sunspot_cell', :git => 'git://github.com/zheileman/sunspot_cell.git'

gem 'sunspot_solr', :git => "git://github.com/sunspot/sunspot.git"
[更新]：截至 2013 年 4 月 4 日：我尝试了以下步骤，但仍然没有运气：请检查详细信息，也许这将帮助您了解我是否朝着正确的方向前进。

4. Ensure config file is correct (solr/conf/schema.xml)
I used this link for schema.xml: http://stackoverflow.com/a/14700918/649868 and overwrite schema.xml file under {PATH_TO_APP}/solr/conf
5. Run Sunspot re-index
${PATH_TO_APP}: bundle exec rake sunspot:reindex
--backtrace
rake aborted!
RSolr::Error::Http - 404 Not Found
Error: Not Found
Request Data: "<?xml version=\"1.0\" encoding=\"UTF-8\"?><delete><query>type:JobSeeker</query></delete>"
我注意到的一件事是，当我执行 bundle exec rake sunspot:solr:start 命令并检查日志文件时，我发现了这一点：
SEVERE: null:org.apache.solr.common.SolrException: Unable to create core: development
Caused by: org.apache.solr.common.SolrException: Cannot create directory: /data/APP_NAME/current/solr/data/index
但是当我访问这个目录时，索引文件夹就在那里。
有趣的是，solr 在生产模式下创建了 solr.xml 文件，而在我的暂存环境中却没有。请参阅 solr.xml（更改后）：
<?xml version="1.0" encoding="UTF-8" ?>
<solr persistent="true">
<cores adminPath="/admin/cores" host="${host:}" hostPort="${jetty.port:}">
<core name="default" instanceDir="/data/APP_NAME/current/solr" dataDir="/data/APP_NAME/current/solr/data"/>
<core name="development" instanceDir="/data/APP_NAME/current/solr" dataDir="/data/APP_NAME/current/solr/data"/>
<core name="test" instanceDir="/data/APP_NAME/current/solr" dataDir="/data/APP_NAME/current/solr/data"/>
</cores>
</solr>
对此有任何想法吗？
[更新]：截至 2013 年 4 月 5 日，我在生产实例上部署了一个新版本，之后，当我这样做时：
$ RAILS_ENV=production bundle exec rake sunspot:reindex --trace
我懂了：
** Invoke sunspot:reindex (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute sunspot:reindex

Tasks: TOP => sunspot:reindex
下面是我的模型：
class OccupationData < ActiveRecord::Base
attr_accessible :onetsoc_code, :title, :description
searchable :auto_index => false do
text :title
text :description
end
end
尝试通过指定 RAILS_ENV=production 来运行所有 sunspot rake 任务，并交叉检查 SOLR 是否以 ROOT 或 deploy 运行，并得到以下信息：
/data/APP_NAME/current $ ps -ef | grep solr
deploy 2342 1 0 Apr04 ? 00:00:30 /usr/lib/jvm/sun-jdk-1.6/bin/java -Djetty.port=8983 -Dsolr.data.dir=/data/APP_NAME/releases/20130404095808/solr/data/production -Dsolr.solr.home=/data/APP_NAME/releases/20130404095808/solr -Djava.util.logging.config.file=/tmp/logging.properties20130404-2342-17k2tsp -jar start.jar
deploy 9770 9461 0 06:42 pts/0 00:00:00 grep --colour=auto solr
它告诉我 SOLR 正在部署中运行。我什至无法提供 SOLR 日志，因为失败的 sunspot:reindex 也不会生成任何日志级别信息。:-(
2013 年 4 月 9 日 - [更新] [解决方案]
在重新建立索引后，我终于找到了解决方案。该错误是由于 Gemfile 中提到的错误 gem 而发生的。
这是我的 Gemfile 的旧副本：
gem "sunspot", "~> 1.3.3"
gem 'sunspot_rails', '~> 1.3.0'
gem 'sunspot_cell', :git => 'git://github.com/zheileman/sunspot_cell.git'
gem 'sunspot_cell_jars', :git => 'https://github.com/mrcsparker/sunspot_cell_jars.git'
gem 'sunspot_solr', :git => "git://github.com/sunspot/sunspot.git"
当我浏览此链接：https ://github.com/mrcsparker/sunspot_cell_jars时，我知道我必须使用更新的 sunspot_solr gem 才能使其正常工作。
所以我正在使用：
gem 'sunspot_solr', :git => "https://github.com/mrcsparker/sunspot.git"
然后我再次使用“rails g 命令”创建了 JAR 文件，当运行 sunspot:reindex 时一切正常。希望这会对某人有所帮助。
